Here are piston,compressed valve base and connecting rod bas in the shock absorber.Shock absorber has a complex construction,it’s small but has multiple holes,it also requires high precession and good elasticity,all of the producing demands require PIM process. From 1970 s,it started to produce piston and connecting rod by PIM process. At present,each car consumes 3-6kg PIM components annually,while it is …

Materials of PIM Comparing with traditional casting process,PIM has its own chemical formation,physical property and mechanical property,such as interspace ,material organization,no segregation. PIM processes save material and producing energy,have better property and high precision,  its products are adequate to be mass produced. On the other hand,PIM processes could produce the products with complex construction,PIM industry in automotive parts has a bright future. PIM …

In recent years,china automotive industry has been keeping enhancing, in the mean time,there is lack of huge demand of quantity and good added value. China automotive PIM market potential is going to be the growth of a blowout type. According to statistics, consumption of automotive PIM products is in the majority of total consumption of PIM products.it is 90% in America,it …
