Product Description
CISRI Metal Injection Molding (MIM) plant has the capabilities to achieve an annual production of 300 tons of MIM products of different alloy powders, Annual output extends to 120 million pieces. Now we can research and develop many kinds of alloys and various new products to meet the demand of precision parts for many industries. It 's honored to be the certified supplier for more than ten renowned companies around the world. With 90% of the products exported to Japan, USA and Europe.
Main product series:
W, Mo, tungsten alloy products; Tool steel products; SUS316L, SUS440C, and 17-4pH stainless steel products; Low alloy steel products; Super-alloy and heat resistant alloy products; Titanium alloy products
Metal Injection Molding (MIM) advantage:
1. Directly manufacturing small sized part (0.1-200g) with complicated geometric shapes
2. The parts tolerance can be held to +/-0.1~0.5%, glabrous surface, up to Ra3.2.
3. The parts made by Metal Injection Molding (MIM) have high relative density (95%-99%),
4. More consistent microstructure and higher mechanical property.
5. High efficency and economic solution for mass production in high volume.
6. Extensive processing for many materials
