>> 16 cavities pneumatic valve hot runner preform mould

Computer simulates tensile test is adopted in preform mould manufacture. By using multilevel and double conicity location technology, each cavity lock the mould soly to ensure mould coaxiality error between 0.05 and 0.06mm. Mould cavity steel and core steel are S136 (imported from Sweden) and 718 with hardness ＞HRC45. Screw is made according to international standard of nitriding steel with hardness ＞HRC60. Hot runner is from Japan. Free of cutting sprue to save labor. Advanced processing equipment adopted to make inchangeable cavities and cores. Fully automation production can be realized to compete with world level moulds
