Metal injection molding with cemented carbide
The MIM-metal injection molding with cemented carbide is a new technology.Cemented carbide with high hardness, high strength, good wear resistance, corrosion resistance, high temperature resistant,which is an indispensable material in metal processing, mining, oil drilling, defense and military. Traditional methods of cemented carbide production is powder metallurgy( PM process), it can only produce simple products, which limit the application range …
Pore sealing method of powder metallurgy products
Because of powder metallurgy products contain a certain porosity, direct plating could’t reach a good surface quality, while remaining in part the pores plating solution is difficult to remove and cause internal corrosion. Secondly, during the electroplating process, when the article from one tank to another tank when the liquid remaining in the pores of the solution can contaminate the …
Powder metallurgy die
Powder metallurgy die slide block in a wedge mechanism similar to injection mold and die casting mold side parting and core pulling mechanism, just two different roles, the former is in order to solve the problem of powder metallurgical product density consistency and along the axis of the unequal height size in the powder used in the profile with powder …
Why powder metallurgy sintered parts is small
Powder metallurgy forming technology, most pressing forming and injection molding parts, so that the size and shape of the complex degree is limited. Powder metallurgy products have higher hardness and wear resistance, but as the shaft fatigue resistance can not be guaranteed, a small defect, it may lead to the destruction of. Powder metallurgy is unsuitable for the larger gear, the …

Powder metallurgy HSS Cutting Performance
In recent years, along with the powder metallurgy HSS Cutting Performance, high speed steel tool market share rose. Compared with ordinary high-speed steel cutting tools, powder metallurgy HSS Tool higher hardness, toughness and better, more resistant to wear, so in some application areas, powder metallurgy high-speed steel has gradually replaced the brittleness, in cutting impact prone to shatter the whole …
Powder metallurgy car parts
Powder metallurgy car parts powder metallurgy structural parts are mainly used in automobile manufacturing. In the early 60 century yntil the powder metallurgy technology was born,the parts was produced by powder metallurgy technology for the most part is oily self-lubricating bearing metal.With the progress of technology and continuously improve the performance of powder metallurgy parts, after 1965, the development of powder metallurgy structural …

The similarities and differences of powder metallurgy and casting process
Powder metallurgy is a metal powder as raw material, through pressure molding, sintering and subsequent processing of metal products, now can also ceramic forming, tungsten alloy forming, powder metallurgy is a machine with less or no excellent batch production method, can under the lower cost, making complex shape, high structure strength of the parts, under the low cost of mass …
Precision Powder Metallurgy Sinter Mechanical Parts MIM Factory
The sintering Purpose-to increase strength & hardness of a green compact Carried out at a temperature below the highest melting constituent. Furnaces may be either the electric resistance,gasfired or oil fired type. Principal variables-temperature(generally within 70-90% of the melting point of metal or alloy),time(10min.-8 hours)&furnace atmosphere. Sintering process is concerned with -diffusion(surface of particles as temperature rises) -densification(decreases porosity,increase particle …
