Metal Injection Molding Titanium Alloy Mobile Phone Middle Frame MIM Parts

In addition, titanium alloy has the characteristics of low thermal conductivity, severe work hardening, high affinity with cutting tools, and small plastic deformation. Stainless steel has high high temperature strength and high temperature hardness, large cutting force, chips are not easy to break, easy to bond with cutting tools, and low thermal conductivity. Due to the poor cutting performance of the processed material, the blank is usually a bar material-which means that a lot of metal needs to be removed.

Metal injection molding completely changes this situation. Titanium feed is made by mixing titanium powder with a binder. MIM (Metal Injection Molding) is the abbreviation of metal injection molding. It is a molding method in which a plasticized mixture of metal powder and its binder is injected into a model. It is to mix the selected powder with a binder first, then granulate the mixture and inject it into the required shape.

Metal Injection Molding (MIM) Production Process and Application Overview

The MIM manufacturing process generally includes: mixing and granulation, injection molding, degreasing, sintering and secondary treatment.

Main Technical Features Of Mim Process

1. Suitable for forming various powder materials, the product application is very wide;

2. High raw material utilization rate, high degree of production automation, suitable for continuous mass production.

3. Can directly form small parts with complex geometric shapes (0.03g~200g);

4. High part size accuracy (±0.1%~±0.5%), good surface finish (roughness 1~5μm);

5. High product relative density (95~100%), uniform organization, excellent performance;

MIM process combines the flexibility of injection molding design with the high strength and integrity of precision metal to achieve a low-cost solution for extremely complex geometric parts. The MIM process is divided into four unique processing steps (mixing, molding, degreasing and sintering) to achieve the production of parts, and whether surface treatment is required is determined according to product characteristics.
