PET preform mould requires high precision, the difficulty lies in the thin wall of the test tube, the concentricity of the mold is difficult, the output of the test tube is relatively large, 8 cavities, 16 cavities, 32 cavities are relatively common, so the steel material of the mold should be selec

The long-term use temperature of PET preform mould can reach 120 ℃, and its electrical insulation is excellent. Even at high temperature and high frequency, its electrical properties are still good, but its corona resistance, creep resistance, fatigue resistance, and friction resistance are poor. ,

PET preform mould is designed by 3D computer drawing, which can be matched with various brands of machines at home and abroad. Molds for PET easy-open cans, mineral water bottles, hot-filling bottles, carbonated beverage bottles, liquor packaging boxes, etc. What are the characteristics of PET prefo
