1, the first is the choice of raw material of resin, high density PE pipe resin is according to the material used by LCL and MRS value choice. In which MRS is different, so when choosing resin, want to combine the use of products to select the correct raw material properties and molding process requirements.
2, colorants, chooses the colorant should has good compatibility with resin, water extraction rate is low, its pay want to consider the influence of the molding machine and mold, PE pipe colorants in resin melt molding process, will lead to product surface deposition in the mold surface quality defects.
3, production equipment, polyethylene pipe, PE water supply pipeline equipment has: extruder, head, or mold, vacuum sizing device, cooling device, tractors and so on.
4, auxiliary equipment, the cooling device has a fixed pipe diameter, PE pipe appearance bright and clean degree increase, pipe mechanics performance improvement. The stability of the traction device, make pipes with a certain thickness and tolerance dimensions.
