Matters needing attention in the operation of MIM injection molding process

2019-12-10

1, how to choose metal powder

Metal MIM injection molding process: pf-3f, phenolic -5 floor sintered density, pf-10f pf-15f four metal powders at different sintering temperatures. It can be seen that within a certain temperature range, the higher the sintering temperature the greater the sintering density, the smaller the sintering temperature. Within a certain range, the larger the size of the powder, the greater the sintering density. Spherical powder is conducive to improving the density of vibration, improving load-bearing ability improving sintering density.

2. How to choose the gate overflow hole?

The door should be in a higher position in space, then drop the melt in the mold friction feed, drop the injection pressure, reduce the possibility of product deformation. In addition, the planning of the flash point is also very important. The flash point is used for loading during cold injection molding to ensure product consistency.

3. The share of metal powder binder.

MIM injection molding process points: viscosity with solid content added, when the solid content reaches 62%, after injection, viscosity sharply added, so that the solid content limit (maximum 62%). When the binder is enough, there is a gap between the two, which will affect the powder products. The mechanical strength of the binder is too high, the solid content is too low, affecting the defatting sintering shortening rate.

The metal MIM injection molding technology only has the shape of the plastic injection molding technology, but also has the characteristics of its shape mass production, has the physical, chemical mechanical characteristics which are close to fine casting forging. It has a common advantage in the preparation of near net shape products with three dimensional messy shapes, even arrangement of structure high performance.
