The catalytic debinding is a new degreasing process developed in recent years, which is also called Metamold Degreasing Process. Its working principle is that the organic carrier molecules are broken down into smaller and volatile molecules by using catalysts. 

Since the emergence of MIM technology, a variety of cemented carbide MIM process paths have been formed with the different binder systems, and degreasing methods have also varied. Wiech was the first one that used in large scale. 

Based on solvent extraction degreasing process, a new degreasing process was developed after improvement, which is so called water extraction degreasing. The binder during the process can be divided into two parts.

Tungsten alloy fishing sinker, a kind of fishing equipment, is one of the most important tools in sea fishing tools. Its fishing line can be thrown faster and farther, and you can fully enjoy fishing.
