design different knids of mold structure,such as Long Tail Mold, Short Tail Mold,Pneumatic Valve Mold,etc. old cavity from 1 to 48. lectric control system with simulating stretch testing to improve yield rate. dopt advanced technique to make each cavity self-lock,and ensure mold concentricity(tolerance less than 0.08mm). the materials of core and cavity are made of mirror corrosion resistance or plastic mold steel imported from Sweden or Germany. international standard screw neck, imported nitrided steel with high hardness and long life time. dopt advanced hot runner system with point to point control system,ensure uniform heating,which brings high-quality products. alves gate mold without tail,reduce the labor force. t least 2 million times life-time guarantee.
