Blowing machine die from the die body (mold heart, die cylinder mold ring) and a heater (heating coil), regardless of the composition of two. First selection is to choose the appropriate material.
The second step is forged, forged material into the rough part of the embryos die, forged over the molecular structure of the embryo is more dense. The third is carried lathe, die in accordance with the design drawings car out of the die, in the lathe, as far as possible with high precision lathes, lathes and technology experienced chef car. The fourth is polished, the car good runner mold part polished finish better, blown film, the better, the less the Silk Road. The fifth is chrome, the flow path portion of the polished chrome-plated mold, the flow path portion of a layer of hard chromium, increase the wear resistance and corrosion resistance of the die and then polishing can not damage the mold retention and easy to produce coke material. Finally, the part of the mold is installed, and then put the heating coil even done.
