Status of Self-made POM Feedstock for PIM

POM based feedstock was first invented by the BASF. This feedstock system has been around for over 25 years since 1996. In China, there were over 70% of MIM companies have accepted and widely adopted MIM product manufacturing since 2002. In the early years, stainless steel and iron-based metal alloy powders were only used for POM base feedstock. After the patent expired, more than 50 Chinese companies have researched and manufactured POM based feedstock materials. Based on Dr Q own research and experience, this feedstock has also been successfully applied to other metals including metal(include cobalt, nickel, tungsten, titanium, and aluminum) and alloys. Also expanded to include ceramic materials, alumina, zirconia, and ferrite oxide. POM based feedstock can be de-binding using oxalic acid catalysis, significantly reducing the environmental hazards of PIM industry. This report provides a comprehensive description of the current status of POM based feedstock development.
