Hot runner titanium zirconium molybdenum bar is rectangle molybdenum alloy bar, and used in hot runner system for its good performance.
TZM bar is making from molybdenum powder and doped powders. It has been much difficilty in manufacturing, because of the mixing of titanium and zirconium with molybdenum. Molyddenum bar is made directly from moly powder, but TZM should be more processes of mixing. And sincerely it took more time than molybdenum. After mixing, the powder is going to the rubber mold for shaping into bar, then sintering, swaging in order to increase the hardness and density. Finally for testing.
