Precautions in Metal Injection Moulding Production

Choose high quality metal powder

In a certain temperature range, higher sintering temperature and higher sintering density increase with sintering temperature. In a certain range, the larger the powder size is, the larger the sintering density is. The spherical powder is conducive to increase the vibration density, increase the bearing capacity and increase the sintering density.

Powder to binder ratio

The viscosity increases with the increase of solid content. When the solid content reaches 62%, the viscosity of metal powder increases sharply after injection, 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 binder is too large, the solid content is too low, which affects the degreasing and sintering shrinkage, which has a great impact on the quality of metal powder metallurgy products.

MIM injection molding technology can not only produce complex and accurate new material products, but also mass production, with perfect physical properties and surface properties. The surface can be mirror polished, which is a high-performance near net molding technology, with high precision, good quality, fast molding, high efficiency and low production cost.
