The fifth generation of metal processing technology - metal powder injection molding

The fifth generation metal metal powder should have the following characteristics:

1. Fine particle size: The smaller the powder particles, the larger the surface area, which is beneficial to enhancing the activity and plasticity of metal powder and improving the compactness and mechanical properties of molded products.

2. Uniform particles: Uniform distribution of particles can ensure the uniformity and consistency of feeding, avoid problems such as holes and defects, and improve the quality of the product.

3. Close to spherical: Spherical particles have lower surface energy and better fluidity, which is conducive to the fluidity of feeding and the smooth progress of the molding process.

4. Easy debonding: The debonding performance of metal powder affects the feeding and demoulding operations during the molding process. Good metal powder should have good debonding performance to reduce losses and defects during the molding process.

5. Uniform sintering shrinkage: Metal powder will shrink during the sintering process. Good metal powder should have uniform shrinkage properties to avoid problems with product deformation or dimensional inconsistency.

To sum up, good metal powder should have the characteristics of fine particle size, uniform particles, nearly spherical shape, easy debonding and uniform sintering shrinkage to ensure the performance and quality of MIM products.
