4 major issues of PIM Technology

In the late 90s, there were nearly 300 PIM factories running around the world. However, the real problem is slowly emerging, how to solve the following 4 issues became the key to PIM!

1 defect control: how can we eliminate weld marks, cracks, voids, and other defects?

2 improve process yield: when you form a yield of only 80%, it is difficult to be profitable.

3 dimensional control: as far as possible to achieve the same size, the same shape of the product.

4 carbon control: bonding agent is very easy to pollute the product, so it is difficult to achieve the specific requirements of the carbon content of heat treatment steel; therefore, even today, low carbon stainless steel is very difficult to do it out of PIM.
