The heat treatment process in MIM production

After 30 years of development, our country Guangdong area is finally formed today's complete market economy oriented pattern of specialized production heat treatment. Of course, now the Guangdong heat treatment industry in addition to produce mold and its accessories, also produce a large number of mechanical parts, hardware accessories, etc. But the mold heat treatment is still the main products of the industry, now still occupies more than 60% market share. At present, Guangdong heat treatment industry group has about 600 factories, most factories has mold processing business.

In mid and late 1980’s, the endeavor to reform and opening up of market economy are springing up in Guangdong area. Household electrical appliances, light industry machinery, metal products, furniture, and aluminum and stainless steel material manufacturing developed rapidly. Especially the Pearl R0iver Delta region, as the pioneer of reform and opening up, the market consciousness, exploring spirit, reform, and economic development and capital accumulation are changing with each passing day.

Due to the drive force of rapid development of the manufacturing industry chain, a considerable scale heat treatment industry group was born at the right moment in Guangdong where is almost blank in before. And experienced social production, mass production and until the specialized production process. While the start of Guangdong heat treatment industry, has connected with the development of die and mould industry. According to introducing, due to the manufacturing industry fast development, the mould demand is very big, thus different sizes of mould processing plants in the Pearl River Delta region dotted with soon.

But heat treatment as a key processing in mold manufacturing chain, in the 80's almost could not be found in the Pearl River Delta region, guangdong has no professional heat treatment factory. Large number of molds had to be sent to Guangzhou large enterprises and institutions of higher learning and scientific research institutes affiliated internal heat treatment factory for heat treatment. But doing so often have the "far water does not put out near fire" feeling, to the entrepreneurs who see "time is money, efficiency is life" at the forefront of reform and opening-up, there is no other better ways. It is in this background, firstly in the Pearl River Delta region began to initiate some private heat treatment factories engaged in the mold heat treatment. In these private heat treatment factories, some attached to the mold factory, some are professional factories providing services to featured products. Nanhai district, Foshan city, such as large-scale aluminum manufacturing industry "raises" a lot of heat treatment factories specialized production of aluminum extrusion die. Demand for MIM mould are also moving in Shenzhen area promoted Shenzhen mold industry and the development of heat treatment industry. 

breaking pads made with powder metallurgy

With increasing car ownership in our country, the production of brake pad is also increasing year by year. Brake pads is the key components of train brake system. The quality of the high-speed rail brake pads is directly related to the train speed can slow down and stop in time, called "the patron saint of life".
With the rapid development of high-speed railway in China, its various performance requirements also corresponding increase, especially puts forward more strict requirements on braking performance. The braking power and speed of the train is cubic relationship, that is to say, the train speed double then braking power requires increased 8 times. High-speed train braking force mainly include electric braking force and friction, the friction braking is train safe parking final guarantee. Friction braking force comes from the friction between the brake disc and brake pads on the braking system. And in the braking system brake pads performance has very big affect on the train braking effect. Brake pad materials at home and abroad mainly experience metal, alloy and powder metallurgy etc.
In the world there is only a few countries such as Germany, France and Japan can produce high-speed train brake pad. Among them Germany Knorr company Monopolies more than 80% of the global high iron brake pads market. High-speed trains in China since its opening,  the brake pads of braking system relies on imports for long-term. Import brake pads has problems aush as high price, long cycle of supply, spare parts supply not in time and poor after-sales service. High-speed rail brake pads is n technology protection period before 2012, has been importing foreign products. In recent years the domestic represented by Tianyishangjia and PuRan private enterprises gradually enter the field of high-speed rail brake pads. Tianyishangjia in September 2013 got seven models 5 types of brake pads CRCC certificate of railways product, PuRan got CRCC certification in 2014. In 2015, BoShen tool has finished the high-speed train brakes 1:1 brake friction wear performance test.

Powder metallurgy become one of the three largest benefit links of wearable devices

Since the beginning of the "smart wave acceleration innovation, Chinese enterprises rise" report to repeated analysis Google will lead the wave of innovation for the next five years. Apple will accelerate innovation, wearable devices will be another hot spot after smartphones, further analysis is as follows:"from small to big, and then from big to small" the cycle of 2009 apples open smartphone wave, As smartphones screensize grow from 3.5 inch to 5-6 inches, now it is limited. Future consumer electronics innovation will enter the era of frombig to small size, all kinds of wearable will be released next year densely. Smart watches, apple iWatch went draw ahead(there will be the product distribution of all kinds of class), Google xWatch behind, a large number of imitators. 

Smart glasses, GoogleGlass user version is more and more close, a large number of imitators to follow up, besides xEye etc. new products also in research and development. Wearable devices via bluetooth 4.0 technology and sensor technology will further solve human entertainment, social, life, education and health care needs. And explore and innovate applications outside of all kinds of consumer electronics.

FPC, mems, and powder metallurgy: three big benefit links of wearable devices. The weekly newspaper and report
analysis for many times, after the outbreak of wearable equipment mems, FPC and powder metallurgy are the three most benefit industries. The combination of these three application will bring more user experience, more data sensing, more deformation application. Make people's entertainment, work, social, education and health care demand combine better.
