Metal Injection Molding (MIM) Medical Parts

Product Description

Metal injection molding (MIM) is a high-tech near net shaping process to mass-produce small metal parts with complex shape, high precision and good performance. We have accumulated twenty years of experience with tools designing and machining, self-binder system and advanced debinding-sintering furnace. Stainless steel, low alloy steel, tool steel, heavy alloy, tungsten carbide of MIM parts of AT&M with high accuracy, intensity and complexity have been widely used in medical, automotive, mechanical and consumer applications. Over 80% of MIM parts exported to abroad, such as Japan, USA and E. U. The factory has certificated with ISO9001/14000, GB/T28001 and TS-16949.
Characteristics
More homogeneous microstructure, higher density between 95%-100% of theoretical density
Surface without polishing better than Ra. 1.0 tolerance without rework can be 0.3%-0.5% of blueprint dimensions
Consistent quality and high production efficiency, raw materials can be reused in mass production, costs can be sharply reduced
Applications:
Medical, Automotive, IT, Mechanical, Consumer applications
