After processing, the pipe making mold must undergo a heat treatment process to ensure the surface hardness of the pipe making mold. In this way, the pipe welding process can effectively save wear and tear, extend the life cycle of the welded pipe mold, and reduce costs for the enterprise. So how many kinds of mold heat treatment methods? Let me briefly explain to you.

Pipe making mold heat treatment methods include vacuum heat treatment, nitriding treatment, cryogenic treatment, etc. These can change the hardened layer on the surface of the mold. The effects of different mold heat treatment methods are also different, and the prices are also different, so that the price of pipe making molds is different. The cooling methods after mold heat treatment are oil cooling, air coolingcoolin Cryogenic cooling costs highly. Each welded pipe mold manufacturer has different requirements, different work methods, and different kinds of effects. It depends on the requirements of the merchants. There is still a lot of knowledge about the heat treatment of the welded pipe mold. I will not say that much.
