the development of powder metallurgy technology in injection molding

Powder metallurgy forming technology is an important part.Powder metallurgy new technology, new craft appear constantly, will promote the rapid development of high technology industry, will also bring bright prospect material engineering and manufacturing technology.At present, the powder metallurgy industry overall technical level is low, backward technology and equipment, great gap compared with advanced foreign technology.Therefore, vigorously developing powder metallurgy new technology research, to enhance the grade of the powder metallurgical products in China and the technical level, shorten the gap with foreign advanced level has very important significance.

Powder Injection Molding is Sustainable

From point view of energy sustainability, general manufacturing process need a few traditional heating and re-heating process to forming. But when use atomized steel or iron powder, only  need melting scrap steel one time. All other hot working operations are carried out under the temperature below the melting point, which not only saving energy, and can be made into the final shape with required material performance and mechanical performance. By contrast of material utilization in powder injection molding process, found that the energy of manufacturing powder injection molding parts is 44% of required by forging, machining parts.

the application of powder metallurgy gear

The powder metallurgy parts in automobile, motorcycle proportion rising, is one of the most widely used powder metallurgical gears.Whether by weight or by the number of parts, powder metallurgy in automobile, motorcycle gear proportion are is far greater than any other in the field of powder metallurgy parts.Therefore, from automobiles and motorcycles in the proportion of powder metallurgy parts increases as you can see, powder metallurgy gear in the powder metallurgy parts in a position of rapid development.If the component characteristics, belongs to structural parts, gear and structural parts in the entire iron base parts of absolute weight also is far greater than other categories of powder metallurgy parts.

How to Improve Powder Metallurgy Stainless Steel Performance?

Due to the internal pore, mechanical properties as well as wear and corrosion resistance of powder metallurgy stainless steel decreased greatly, which seriously limits its application. Studies show that almost all performance of powder metallurgy stainless steel increase along with density increase. Therefore, how to improve the density of powder metallurgy stainless steel, reduce its porosity, are key problems to improve the performance of powder metallurgy stainless steel.

The MIM Process of Three Steps

MIM process(http://www.zcmim.com/helps/mimprocess.html) requires three steps:

(1) In condition of heating, pressure, injection the mixture of powdered metal and thermoplastics (or other binder) into mold cavity (similar to thermoplastic injection molding).

(2) Removing binder by heating or melting, only the metal powder left.

(3) Sintering the metal powder. Sintering temperature should be lower than the melting point of metal, but enough to make metal powder combined into solid metal (actual solid metal density is more than 96%).

Metal Injection Molding Process Applied in Sewing Machine Parts

Metal injection molding(http://www.zcmim.com/faq.shtml) technology was first introduced by national 863 plan, to produce high density, high precision, high strength, complicated 3D shape parts. It has the advantages of low cost, high efficiency, good consistency and good abrasion resistance, strong ability to resist high temperature, and easy to mass production. With the production of sewing machine industry as example, traditional production method is generally take cold extrusion process. Though its cost for blank is lower, it requires more than 200 times procedures, high artificial cost and low efficiency. Shuttle blank with metal injection only needs lathing once on each side, as much as 10 procedures can complete finish goods, saving more than 100 procedures than traditional process, greatly shorten the production cycle and save a large amount of labor.

application of powder injection molding technology drying machine

The application of powder injection molding technology is our immeasurable. Technology of powder metallurgy injection molding is also used in many places. The drying machine has a very significant effect on the application. Rotary metal powder dryer by rotary body, lifting plate, driving device, and the device made of a sealing ring, when the metal powder is transferred to the top, then enters the cylinder, can be copied to the rear plate rotation, in the dryer inclined, the metal powder by gravity and rotary force the role of slow down, on the other hand, has been repeatedly copying board toss, toss the metal powder after drying cylinder continuous uniform fall to form a uniform metal powder like a curtain flow. The drying of the metal powder is accomplished by the heat exchange with the strong hot air flow in the cylinder.
