What's the MIM technology and its advantages and features.
it’s suit to do mass production with complicated shapes;
1, MIM is an advanced metal forming technology that use injection molding machine to manufacturing precision and complex metal parts, which combines the advantage of PM and plastic injection molding.
it can use all kind of metal material(such as stainless steel, iron, ceramic and titanium, etc)
its relative density can achieve more than 98%
its finished products is close to final products, reducing the post-treatment cost, and then save production cost
compared with tranditional CNC and precision casting process, the structure are more even and preformance is much better
compared with PM(Powder Metallurgy), MIM can produce more complex shape and better preformance metal products.
