l After that, drilling the hole and set the water way in the preform mould and also do other treatment.
l Preform moulds high speed milling machine and finish processing
After we finish the rough tooling then does the finish milling, which is ensure the mould accuracy and not deformation. We will do all the finishing processing on the core/cavity/screw/mould base.
