2016 five years to break down trend of steel prices mainly by asset allocation under the drought risk transfer, macro economy improves, macro factors such as comfortable on the financing side and the fundamentals of supply and demand balance, cost drive factors such as the impact. 1, the macroeconomic environment improved obviously 2014-15 years experience in the economy fell back quickly, the domestic economy this year or for some respite.In the first three quarters year-on-year GDP growth at 6.7%, obvious steady growth in 2016.Domestic manufacturing purchasing managers' index (PMI) from then started showing signs of recovery in the second quarter, third quarter appeared relatively strong rise;PPI index ended 54 consecutive months in negative territory, become a full member in September.Supply side injected new vitality into the economic reform.By eliminating backward production capacity, industrial enterprises to leverage, make domestic industries from deflation pattern, domestic inflation and moderate rise.The economy stabilises picks up is one of the important influence factors of commodity prices is strong. 2, under the background of asset allocation waste money wheel dynamic effect is obvious Domestic steel products in 2016 financial manifest attributes and rebar, for example, phase spot both correlation coefficient as high as 98%, linkage effect is obvious.Steel futures prices is one of important factors influencing spot market movements.Due to large amounts of money to accelerate the volatility of futures products, harden drop stop number increased significantly, according to figures from the zhuo and information, as of December 7, 16 rebar zhang drop stop, and only four times in 2015, capital hype phenomenon is obvious. 3, the continuous depreciation under the effect of raw material costs significantly higher 2016 RMB exchange rate has been falling for commodities form relatively obvious cost support.Iron ore and other bulk raw materials price premium effect is obvious, it is also a domestic goods especially industrial products one of the important factors in the price of the renminbi devaluation leads to purchase raw materials costs, and raise industrial manufacturing costs.Excluding depreciation caused by raw material prices, some domestic raw materials such as coke pushing the rise in prices is also an important factor of steel cost.In 2016, according to zhuo gen information monitoring data show that domestic coking coal price from 600 yuan/ton price increases to a maximum of 2120 yuan/ton rose more than 200%, the coke in the steel raw material costs accounted for more than iron ore in early October.In October after the steel prices rising prices, driven mainly by coke is a typical cost-push up. 4, supply side reforms to boost capacity and environmental factors rising steel prices 2016 and baosteel, wisco, published throughout all the provinces to aggregate ironmaking production task is 45.555 million tons, 87.99 million tons of steel.The effective capacity total more than 40 million tons of iron and steel, hebei effective capacity of more than 19 million tons, with ironmaking effective production capacity of 9 million tons.And in the second half of intermediate frequency furnace steelmaking inspection, to a large extent affected the supply of steel market expectations, in the key stage of steel price form relatively obvious support;Other environmental factors also play an important role in 2016, tangshan exposition, the G20 meeting in hangzhou and after November fog governance also help 5, a slowdown in exports Domestic steel prices rose sharply weakened price advantage, square steel export tax rebate check, anti-dumping, export growth, but the overall level is higher. In the first half of growth momentum, up to 10.94 million tons (June), the second half of the overall exports showed a trend of decline, at the level of 1 million tons per month.October 1 - China's exports of steel 92.74 million tons, up 0.7% from a year earlier.Imported steel 10.91 million tons, up 2.1% from a year earlier. 6, China's steel exports mainly depends on Asia China's steel exports in the first 10 big destination countries of Asia, southeast Asia, six, two east Asia, South Asia, west Asia 1;Is the largest South Korea 12.2 million tons, 8.9% growth, Vietnam, 10.07 million tons, 21.2%.Southeast Asia, large-scale infrastructure construction demand rapid growth over the last two years. 7, continue to inventory The improvement of relations between supply and demand and circulation mode change (increase steel mills, traders straight for circulation, shrink back to peak hard) market inventory, steel association focused on inventory levels back to 13 years.Five varieties market inventory: in the same period last year, 8.42 million tons, 7.85 million tons this year, plate stock just drop, thread. 8, the improvement of relations between supply and demand Steel straight for direct proportion. Bank loans, traders prefer stable profit project distribution, shrinking in number 12-14 years traders, such as financing, transformation, bankruptcy after hard to recover. 9, the downstream demand is difficult to see the growth Infrastructure, real estate investment growth, manufacturing investment decline. 10, in October 2016, the national investment in fixed assets 48.4429 trillion yuan (excluding farmers), year-on-year growth of 8.3%, in the name of forecast of 8.2%.Infrastructure construction and real estate growth, enterprise profit decline, capital shortage restrict their investment, low capacity utilization, cause the loss of manufacturing investment growth.

The global economy continues to weaken, overseas export trade depression, many fastener enterprises both at home and abroad, is facing a severe test.Accelerate the economic transformation and structure upgrade is imminent, to develop overseas market is undoubtedly the current fastener industry development of important ways. From the fourth quarter of 2011 to the first half of 2012, the influence of the objective environment, fastener industry development speed or will slow, but since the third quarter of 2012, as the policy in place, the eighteenth big meeting, and the upcoming series of development policy, etc., can promote the further development of the industry.And must adhere to innovation and restructuring, will continue to closely rely on cars, new energy, aerospace, shipbuilding, urban traffic, IT, electronic appliances, construction and other key industries, accelerate the fastener product optimization and upgrading, promoting the healthy and steady development of fastener industry. According to the China fastener industry transformation and upgrading of production and marketing demand forecasting and analysis report preview "statistics: global fastener market size of more than $50 billion, 2012 Chinese fasteners production also is expected to reach 6.8 million tons.But compared with the United States, Japan and other manufacturing powerhouse, fastener industry of our country there is a big gap. Mechanical industry Machinery industry is a major one of the users of fasteners.Due to China for a mechanical components in the important position in the mechanical industry know late, lack of long-term investment, and the poor, poor foundation, weak industry foundation.Especially as China to raise the level of the host machine foundation behind the host becomes increasingly bottlenecks.Today, although the technology transfer, technical innovation, scientific research and development, etc., countries give some support, but compared with the current market demand and foreign level, there is still a big gap, specific displays in: product variety, low level of less, the quality is not stable, early high failure rate, poor reliability. Fasteners as a foundation for machinery industry main product, the development of mechanical industry, also put forward higher request of fastener products.Domestic standard fastener has been oversupplied and high-grade fasteners (high temperature, special shape, titanium compound, specific performance and other fasteners) in short supply, more dependent on imports.National okmo limit "common standard fastener" as development products, "high strength" "encourage the development of current products.High strength fasteners, with the improvement of national industrialization level and technological progress, gradually increase usage. High strength automobile fasteners The visit and survey the 13 domestic automobile fasteners company, companies have been surveyed through TS16949 system certification.About 1500, an average of 1 cars fasteners bolt for the total time of each car is about 2.5 ~ 3.2 h.The type and quality of visible fasteners has important influence on the quality of the host level and vehicle.In this paper, from the process of production of high strength thread fasteners, localization of high strength thread fasteners and supplier quality management is analyzed. High strength thread fasteners products process High strength of threaded fasteners production process for raw material restructuring - cold heading forming - thread processing (thread rolling or rub silk) to heat treatment and surface treatment, sorting, packaging, 10.9 magnitude generally adopts the thread rolling process after heat treatment. Auto fastener materials High strength bolts used steel grades of 8.8 bolt with 35 steel, 45 # steel, ML35 steel;10.9 with 35 crmo bolts;40 cr;12.9 bolt with 35 crmo, 42 crmo, SCM435. Basic raw materials used in domestic fastener is hot rolled state, while the production of fasteners, such as the Japanese steel is basically can cold heading directly state, users need not pretreatment, can reduce cost from the link. Common failure forms of fastener failure have assemble stretch, fatigue fracture and delayed fracture.

"Economic and trade fair" held by the association of fasteners, based on industry, held for many years, has become a tradition in fastener industry, support and welcome of the insiders.Fastener association will adhere to the good tradition, in line with the aim of for industry, for the member service, according to the characteristics and advantages of the industry, through the theme report, information release, exhibition and product display, trade talks, free exchange, business consulting service for the industry, form of all the companies in a timely manner to understand the current industry situation and market demand, access to information, and seek common development. trade, technology symposium in fasteners, tight media show in 2017 in China (jiaxing) fastener industry expo, China fastener national council, "China fastener", "China zhejiang fasteners, tight media and the promotion of micro film exhibition attracted a lot of peer attention, more customers with live directly sign the bill.Tight in the media has been committed to build the most professional fastener enterprises show exchanges platform, become a fastener enterprises show their window, also be fasteners, the driving force for the enterprise to the wider world.

T nut standard. T nut standard GB/T37-88 T nut gb rules on the thread specification for the M5 - M48, class B T bolt T bolt size standards as shown in figure (unit: mm)

Stamping products especially the steel t nuts, can be found everywhere in our life, but you know there are stamping parts service life? Tensile service life of the stamping parts, in addition to depends on the reasonable mould structure, the manufacture of high precision, good effect of heat treatment and correctly choose punching, stretching the outside factors, such as stamping parts installation accuracy, mold the correct use, maintenance and maintenance is also an important link, the following points should be paid attention to: (1) the tensile stamping parts installation should strictly check before use, remove dirt, check whether tensile stamping parts of the guide sleeve and mold good lubrication. (2) the tensile stamping punch and die blade wear should stop using, when grinding in time, otherwise it will rapidly expanding mold parts wear degree, accelerate the mould wear and tear, lower the quality of stamping and die life. (3) guarantee the life of the tensile stamping parts, of the mould to change the spring, should also be regularly to prevent spring fatigue damage impact tensile stamping use.

In our life a lot of products are metal stamping parts, we are clearly that in metal stamping parts processing, if there is no correct operation, probably in the process of machining, metal stamping parts will become a waste, in order to solve this situation, how do we prevent metal stamping parts to scrap? Main measures of prevention of metal stamping parts into waste parts: 1, metal stamping parts used in the raw materials must be consistent with provisions of technical conditions, strict inspection specifications and grades of raw materials, at the same time require high dimensional accuracy and surface quality of workpiece in laboratory tests. 2, used by the press and die tooling equipment, to ensure that in the normal working condition before work. 3, for the procedure specified in each link to, strictly abide by it. 4, in stamping process to ensure that the mold cavity clean, to organize an organized workplace processed workpiece to be well organized. 5, establish a strict inspection system in the production process, stamping pieces must be comprehensive inspection, after inspection qualified can be put into production, at the same time, strengthen the inspection, when accidents should be handled in a timely manner. 6, adhere to the civilization system of production, such as artifacts and transfer ware must use the appropriate workstation, otherwise it will press and bruising affect the workpiece surface quality of workpiece surface.

Stamping is to rely on press and die for sheet, strip, pipe and profiles, such as external force, to produce plastic deformation or separation, to obtain the required shape and size of the workpiece forming method (stamping).Stamping and forging belong to plastic processing (or pressure processing), called the forging press.Stamping of billet is mainly hot rolling and cold rolling steel plate and steel belt. Stamping parts of the light weight and thin thickness, good rigidity.Its size tolerance is depended by mold guarantee, so the quality is stable, generally do not need then through mechanical cutting can be used.Cold stamping metal organization and mechanical performance is superior to the original blank, the surface is smooth and beautiful.Cold stamping tolerance grade and surface state is better than that of hot stamping. Large quantities of medium and small stamping parts production is generally adopted complex mold or multi-station progressive dies.In modern high-speed transfer press as the center, configuration with an open-book, correct, finished product collection, transmission and tooling libraries and quick die change equipment, and use the computer program control, can form high productivity of fully automatic stamping production line.Using new mould material and all kinds of surface treatment technology, improve the mould structure, can get high accuracy and life of the stamping die, so as to improve the quality of stamping parts and stamping parts manufacturing cost. Stamping production process and equipment is developing unceasingly, in addition to the use of traditional press and steel mould manufacturing stamping parts, hydraulic forming and spinning forming, molding, explosive forming, electric water forming and electromagnetic forming and other special stamping forming technology is developing rapidly, the stamping technology level to a new height.Special stamping process is especially suitable for many kinds of medium and small batch production of (or even dozens) parts.For ordinary stamping process, can use simple mould, low melting point alloy mould, group stamping molds and flexible manufacturing systems, etc., organize many varieties of small batch parts stamping processing. All in all, stamping with high productivity, low processing cost, high material utilization, simple operation, easy to realize mechanization and automation, and a series of advantages.Use the composite process such as stamping and welding, bonding, make the parts structure more reasonable, more convenient processing, can use a relatively simple process to create more complex structure.

Welding nuts is mechanical equipment closely connected parts, through the inside of the thread, the same specifications nut and screw, can be connected together, for example, the M4-0.7 nut only with M4-0.7 screw (in the nut, the M4 refers to the nut inside diameter is about 4 mm, 0.7 refers to the distance between the two thread is 0.7 mm). The use of special welding materials such as aluminum alloy, stainless steel, mild steel with high strength, excellent welding performance characteristics.Welding nut, it is a nut, and bolt or screw fastening screw together to the function of parts, all production machinery must be an original, welding nut is mechanical equipment closely connected parts, through the inside of the thread, the same specifications welding nut and screw, can be connected together. Above is what I share with you about the knowledge of the welding nut, hope will be helpful to you.

As we all know our t nuts is made by stamping process,how to ensure the safety during the stamping ,let us have a introduction about it. 1. The semi-automatic and manual punch press brake switch must be installed with both hands, it is forbidden to start switch pedal or one hand press. 2. High impact after adjusted the machine, after normal stamping, close the soundproof box (except 8065 border edge packaging products). 3.

Drilling and milling machine, gloves are forbidden;When using grinding machine to wearing surgical masks and eye shield, protect yourself. 20. Pay attention to drag the mould to prevent falling on the ground (to put the flat car in minimum to just die). 21. It is strictly prohibited to the electrician personnel and maintenance of electrical machines. 22. It is strictly prohibited to air pressure gun aimed at one blow, easy to hurt the eyes. 23. Operators need to wear ear plugs. 24. When he found the machine abnormal switch off the power supply first, then call the technician on duty in time, cannot do STH without authorization. 25. The new employee the first day at work, the team leader must be good to his safety operation specification, the first week to learn every day a safety operation procedures. 26. The machine, be sure to dispatch the machine to the single action, it is forbidden to play moving strip. 27. Under the switch can't store any flammable and explosive. Chase chase 28. Operators are strictly prohibited in the workplace, in order to avoid the wrestling, down products, or hurt yourself. 29. According to the equipment point check card equipment check check content, to pay special attention to punch guidance and brake equipment operation is normal, single and even the impact and function. 30. In small punch (10 t) are installed on the mould, to loosen the guide rail locking device, install the lower die, and then adjust the guide rail travel, until it meets the requirements and locked tightly solid device, the other in a high impact on die, must hit single stroke and lock on the mold after the mold after the hydraulic clamping lock, again for a check-up before production., 31. The discharge or hand took the embryo of a single to send, must use the special tool (pliers, hook), it is strictly prohibited to unarmed, take the embryo.Single switch to hand injury, to double the switch.The machine can't leak, otherwise you will fall down.The power supply not exposed, dangerous. 32. Should wear gloves when pressing plate, concentration, otherwise the injured hand. 33. In the work, first check whether there is any abnormal on equipment operation, such as single, even not clear, the operation is ineffective or electrical failure, to immediately stop looking for technician on duty to deal with in a timely manner. 34. Press foot switch is strictly prohibited, the machine comes with all down. 35. Clean, check the equipment, it must be cut off the power supply after the operation. 36. Cut off power supply, cleaning, scrubbing and working mesa, remove the mold maintenance warehouse, a weekly regularly check the oil lubrication system.

Steel material all over the world, there are 60 ~ 70% is plank, most of which is made by stamping products.Car body, chassis, fuel tank, radiator fin, the boiler steam drum, container shell, motor, electric iron core silicon steel sheet stamping processing.Instruments and meters, household appliances, bicycles, office machinery, household utensils, and other products, also have a large number of stamping parts. Compared with the castings, forgings, pressing with a thin, uniform, the characteristics of light and strong.Stamping can make other methods are difficult to manufacture with rib stiffener, flanging, ups and downs, or artifacts, in order to improve its stiffness.Because use precision mould, workpiece precision can reach micron grade, and repeat precision is high, the specification is consistent, can punch a hole nest, convex sets, etc. Stamping machine Cold stamping generally no longer by machining, or only need a small amount of machining.Hot stamping precision and surface state is lower than the cold stamping parts, but it's still better than the castings, forgings, cutting processing capacity.

The sheet metal surface and internal performance of stamping has great influence on the quality of the finished sheet metal stampings product, request stamping material thickness precision, uniform;Smooth surface, no spots, no scar, no scratch, no surface crack, etc.;Yield strength evenly, no obvious directivity;High uniform elongation;Showed low;Low strain hardening.Stamping is efficient production methods, the use of compound die, especially the multi-station progressive die, it can be finished in a pressure on multichannel stamping process, realize the pick-up uncoiling, leveling, cutting to the forming and finishing of automatic production.High production efficiency, good working conditions, low production cost, general can produce hundreds of pieces per minute. Stamping is mainly classified by technology, can be divided into separation process and forming process two kinds big.Separation process is also called the blanking, and its purpose is to make from the sheet metal stamping parts along the contour line must be separated, and at the same time guarantee the quality requirements of the separation section.Forming process is designed to make sheet metal under the condition of not to break the billet occurred plastic deformation, made into the required shape and size of the workpiece.In the actual production, is often a variety of process integrated applied to an artifact.Cutting, bending, shear, deep drawing, bulging, spinning, correction is several main stamping process.

Some possible problems in the process of metal stamping parts: 1, adhesive, scratches: due to the friction material and punch or concave die in parts or die surface bad; 2, burr: mainly happens on the shear modulus and blanking die, blade clearance between big or hours will produce burr; 3, the line displacement: forming parts, the first contact with the mould parts of the squeezed and formed a line; A foreign body in 4, intensive: uncoiling line (iron, rubber, dust) mixed with causes convex concave; 5, twists and turns: due to the uneven stress, drawbead matching bad or press the slider control bad parts r Angle parts or embossed parts causing twists and turns, strain; 6, wrinkles, due to poor press slide block adjustment, low precision press, air cushion and inappropriate pressure adjustment, punch or caused big edge or r r parts of wrinkles.

Now let us make a introduction for how to test for the stamping products of courses including the test for T nuts products. A. touch test With a clean cloth to clean the surface of the outer covering parts.Inspector need to wear the touch gloves along the longitudinal pressing close to touch on the surface of the stamping, the inspection method depends on the checker's experience.Abrasive grinding if necessary by detection of suspicious areas and verified, but this method is an effective method of quick inspection. B. oilstone grinding 1. First of all, with a clean cloth to clean the surface of the outer covering parts, and then polished with oil stone (20 x 20 x 100 mm or greater), there is circular and hard-to-reach places with relatively small abrasive polishing (for example: 8 x 100 mm semicircle sharpening stone) 2. The selection of abrasive particle size depends on the surface condition (such as roughness, galvanized, etc.).Suggest using fine-grained whetstone.Oilstone grinding basically along the longitudinal direction, and a good joint on the surface of the stamping parts and some special place can also supplement horizontal grinding. 3. Stamping flexible grinding yarn network With a clean cloth to clean the surface of the outer covering parts.With flexible sand nets to stamping surface along the longitudinal grinding to the surface of the whole, any pitting, indentation can easily be found.

1. The same two locking T nuts screw with a bolt, attach a tightening torque between two nut, bolt connection is reliable.The second is a dedicated locknut, need and a locking washers are used together.Dedicated locknut is not hexagonal nut, but a round nut, the nut on the circumference of a circle with three, four, six or eight gap (depending on the size of nut and manufacturers products vary), these a few gap is the focus of tightening tools, and locking washers bayonet card into place. 2. Within the cylindrical surface of the locking t nuts to round thread runs through the thread hole is drilled surface (usually 2, outer circle like 90 distribution), used to screw into the small diameter countersunk head screws, the purpose is to put a thread under direction of the centripetal force, prevent loosen lock nut.Sales on the market at present the quality of a good lock nut on the nut of the inner circle surface with consistent with the lock nut thread copper pieces, used to avoid the radial head screw direct contact with the locked thread and damage to the latter.

The T nuts is commonly used in life and industrial fasteners, one of the biggest problems and hidden dangers in using is loose and sliding, that how to prevent the screw nut and other fastener in use is not loose, not to tell you some locking points below: The first is a locking screw friction.This is the most widely used a way of locking, this way between the thread deputy produce a positive pressure does not change with the external force, to produce a can prevent thread pair of relative rotating friction.The positive pressure by axial or two at the same time to the compression screw pair.If use T nuts,elastic washer, double nut, locking nut, nylon insert lock nut and so on.This way of locking nut for disassembly is more convenient, but in the case of shock, vibration and variable load, the beginning bolt pre-tightening force caused by loose will be reduced, with the increase of vibration frequency, slowly increase, loss of pre-tightening force will eventually lead to loose nut, screw thread connection failure. The second way is to mechanical locking screws.Is to use stop limit screw directly is the relative rotation vice.If use split pin, the steel wire and check washer and so on.Due to not stop pre-tightening force, nut loose back to the stop position when the locking piece to stop work, so, in fact this way instead of locking to prevent loss. The third way is rushed locking screws riveting.After tightening by adopting the method of impact point, welding, bonding, make vice lose caused by the characteristics of connecting thread not detachable connection.The shortcoming of this approach is a bolt rod can be used only once, and remove the very difficult, must destroy the bolt can remove. The fourth way is locking screw structure.Structure is the use of thread vice themselves, that is way down thread locking.Before three kinds of locking approach relies on a third party into the locking force, is mainly refers to the friction, the locking effect is good or bad depends on the size of the force of a third party.The locking structure does not rely on any third party, only rely on their own structure.Mode locking down namely thread locking structure, is currently the most advanced and best way of locking, but not known to most people.

Welding nut Welding nut is a nut is suitable for welding nut, generally can be welded and thicker and welding materials, welding is equivalent to two separate parts into a whole, with a high temperature metal melt together and then cooling, in the middle will join alloy, internal is a function of molecular force, intensity is generally larger than the maternal strength [1].Welding parameters of the experiment to see the size of the weld fusion, according to the size of the fusion adjustment of welding parameters, until the elimination of defects.Of course, the quality of welding and pre-welding treatment, ash removal, grease, etc. Production process editor The welding nut is a kind of fastener with internal thread and used in conjunction with the bolt. The welding nut is a kind of fastener with internal thread and used in conjunction with the bolt.A mechanical part having an internal thread and used in conjunction with a screw to transmit motion or power. Standard editor GB/T, DIN, BS, JB Advantages and disadvantages editor However, due to high temperature, the connected parts will be deformed and cannot be removed. Moreover, some active metals cannot be welded with normal methods, such as aluminum and magnesium. Therefore, it is necessary to protect gas or argon arc welding, which requires processing technology and precision

About the hardware mold manufacturing process performance and use performance, hebei xinyu metal products co., LTD. According to the experience to tell everyone metal mold manufacturing generally through forging, cutting processing, heat treatment and other procedures.In order to ensure the quality of metal mold manufacturing, reduce the production cost, the material should have a good malleability, cutting, hardenability, hardenability and grinding;It should also have a small oxidation, decarburization sensitivity and quenching deformation cracking tendency. Hardware mold manufacturing process performance: 1. Forgability: it has low deformation resistance of hot forging, good plasticity, wide forging temperature range, low tendency of forging cracking and precipitation of reticular carbide. 2. Annealing technology: spheroidization annealing has a wide temperature range, low hardness, small fluctuation range and high spheroidization rate. 3. Machinability: large cutting amount, low tool loss and low machining surface roughness. 4, oxidation, decarburization sensitivity: high temperature heating antioxidant capacity is good, decarburization rate is slow, is not sensitive to the heating medium, produce pitting tendency is small. 5. Hardening: uniform and high surface hardness after quenching. 6, hardenability: after quenching can obtain a deeper hardening layer, the use of moderate quenching medium can be hardened. 7. Quenching deformation and cracking tendency: the conventional quenching volume changes little, the shape of warping and distortion is slight, and the abnormal deformation tendency is low.Conventional quenching cracking sensitivity is low, not sensitive to quenching temperature and workpiece shape. 8. Grinderability: the grinding wheel has a relatively small loss, a large amount of grinding without burns, and is not sensitive to the quality and cooling conditions of the grinding wheel, so it is not easy for grinding damage and grinding cracks to occur. Hardware mold manufacturing performance: 1, small density: plastic density is small, to reduce the weight of mechanical equipment and energy saving is of great significance, especially for vehicles, ships, aircraft, spacecraft. 2, specific strength and specific stiffness high: the absolute strength of plastic is not as high as the metal, but the plastic density is small, so than the intensity (sigma b/ rho), than the stiffness (E/ rho) is quite high.Especially with a variety of high-strength fiber, flake and powder metal or non-metal filler made of reinforced plastic, its strength and stiffness than metal is higher. 3, good chemical stability: the vast majority of plastics have a good resistance to acid, alkali, salt, water and gas performance, in general conditions, they do not react with these substances. 4, electrical insulation, insulation, adiabatic performance is good. 5, wear and self-lubrication: plastic friction coefficient small, good wear resistance, a good self-lubrication, plus high specific strength, transmission noise is small, it can be in the liquid medium, semi-dry or even dry friction conditions effectively work.It can be made into bearing, gear, CAM and pulley machine parts, very suitable for the speed is not high, the load is not big occasions. 6.
