Consideration on Surface Modification of Steel Dies to Reducing the Plastic Sticking in the Forming Process

Plastic parts such as syringe, phone cases, containers, etc. are formed in the mold under the molten temperature and with the high pressure. Plastic sticking to the mold surface during forming process is a serious practical problem for the manufacturing. The sticking limits mold lifetime, reduces pr...
