Precautions in MIM Technology Production of Metal Injection Molding

Precautions in MIM Technology Production of Metal Injection Molding

Metal injection molding (MIM) is a kind of precision molding technology for metal and ceramic parts, which is widely used in powder metallurgy. It can not only produce precision parts, but also mass production. Manufacturing, net near molding technology, is currently widely used in automotive, digital electronics, medical equipment, tools, hardware, aviation and other fields to help the development of various fields. What are the precautions for the production of metal injection molding MIM technology? ABCDPrecise Powder Metallurgy Sharing:

1: Select high-quality metal powder

In a certain temperature range, the higher the sintering temperature, the higher the sintering density, the higher the sintering temperature. In a certain range, the larger the powder size is, the greater the sintering density is. Spherical powder is conducive to increasing the vibration density, bearing capacity and sintering density.

2: Proportion of powder to binder

The viscosity increases with the increase of solid content. When the solid content reaches 62%, the viscosity of the metal powder after injection increases sharply, so the limit value of solid content (MAX62%). When the adhesive is insufficient, there will be a gap between the two, which will affect the powder. If the mechanical strength of the adhesive is too large, the solid content is too low, affecting degreasing and sintering shrinkage, which has a great impact on the quality of metal powder metallurgy products.

3: Gate design

The gate shall be designed to be high, which can reduce the melt feeding amount in the mold, reduce the injection pressure and avoid product deformation. In addition, the overflow hole is designed to be loaded during cold material injection molding to ensure the consistency of powder metallurgy products.

MIM technology of metal injection molding can not only produce complex and accurate new material products, but also mass production. It has perfect physical properties and surface properties. The surface can be mirror polished. It is a high-performance near net molding technology with high precision, good quality, fast molding, high efficiency and low production cost. This is the precautions for MIM technology production of metal injection molding. You need to know more friends. Please pay attention to the update of the official website of zhongwei Precision.
