How to make up for the defects of carbide component components of metal powder injection

The production process of carbonized components is first composite. It is a combination of mixed metal powder and adhesive. It is capable and can produce high -quality products in the control environment. There will be some defects during parts, so thezhongweitechnical team believes that it is better to solve some good measures.

1. Powder select links. In addition to the basic requirements such as granularity distribution and granularity, etc., the hard alloy powder also requires the high purity of the powder to be high and cannot use powder and impurities. The pores are formed in China, causing product defects.

2. Production feed link. Hard alloy powder requires the appropriate adhesive when mixed, and the hard alloy powder and adhesives are fully mixed. During the mixing process, the temperature should be strictly controlled to avoid the volatility and uneven distribution of the adhesive, so that the mixed post -feeding feed It has good streaming performance and viscosity to avoid defects in future links.

3. Form the green link. zhongweiPrecision  believes that this is a key component in the production of hard alloy parts. In order to avoid product defects, it is necessary to pay attention to the reasonable control of mold temperature, feeding volume, injection pressure, pressure time, injection speed, etc. during injection molding process. Effectively avoid injecting green defects.

Some of them are metal injection molded parts precisely made for automobile complete machine factory

4. Skill off the session. Hard alloy skipping, during the dehydration process, if the heating speed of the skilled furnace is too fast, it will cause carbonic defects in the parts. Dahong's new material proposes to use the method of gradually heating up the lipid.
