Process Description
A custom formulated mixture of Metal Powder and binder is injected into a mold. After removal of the green part from the mold, the binder is removed and the part is sintered (solid state diffused) in a controlled atmosphere furnace. The process is very similar to plastic injection molding and high pressure die casting since it can provide much the same shapes and configuration features. |
