This is very important part of the pipe making machine, to use the moulds help to produce different sizes of pipes. We have mature skills, rich experience and standardized production managment and have achieved strong competitive power in this industry. Regarding to the roller sets, there have materials Cr12Mov and SKD11 Or depends on customers’ requirements. The pipe moulds Hardness ranges 60~63HRC, tolerance ranges about ±0.04mm, which can ensure the high precision. The moulds we made can achieve good surface treatment of round pipe with roundness in ±0.05mm and for square pipe plane, subtense angle Not exceeding ±0.05mm.
