DESCRIPTION
MIM is a new near net forming technology of metal parts formed by introducing modern plastic injection molding technology into the field of powder metallurgy. It is a high and new technology developing rapidly in the field of powder metallurgy and industry in recent years. The MIM process steps are: firstly, to meet the requirements of the MIM metal powder and organic binder in a certain temperature under the condition of the appropriate method mix into uniform feeding, then after granulating in heating plasticizing state with injection molding machine into a mold cavity to obtain billet, after chemical degreasing treatment or solvent extraction method, finally the sintering densification of the final product.
Features of MIM products:
1. The geometric shape of parts has a high degree of freedom, which can be used to produce metal parts with complex shapes in a single forming just like plastic products;
2. MIM products have uniform density, good smoothness, and the surface roughness can reach Ra 0.80 ~ 1.6m. The weight range is 0.1 ~ 200g. High dimensional accuracy (±0.1% ~ ±0.3%), generally no need for follow-up processing; 3. Wide range of applicable materials, wide application fields, high utilization rate of raw materials, high degree of production automation, simple process, which can realize continuous mass production;
4, product quality is stable, reliable performance, the relative density of products can reach 95% ~ 99%, can be carburized, quenching, tempering and other heat treatment. Product strength, hardness, elongation and other mechanical properties, good wear resistance, fatigue resistance, uniform organization;
It is generally believed that the development of MIM technology will lead to a revolution of parts forming and processing technology, which is praised as "the most popular parts forming technology in the 21st century".
Production process:
1: product technical exchange → product design → mold design → mold manufacturing
2: metal, ceramic powder, adhesive → mixing → injection molding → adhesive removal → sintering → deep processing (as required)→ inspection → finished products
