Dies and mandrels are the most important parts of elbow, tee, reducer and cap etc. pipe fittings machines. They are precision casting parts and forging parts.

All the dies and mandrels are processed by CNC rough machining, precision machining and two times heating treatment. Two times heating treatment makes the hardness of molds and mandrels up to HRC52-HRC56.

Precision machining and perfect hardness ensures the qualified rate of products and long life span of the dies and mandrels.
