Effects of Plastic Material on Cooling Time in Plastic Injection Moulding
A numerical analysis using a finite volume approach was carried out to study the effect of the plastic material on the cooling time in plastic injection moulding. The polymethyl methacrylate (PMMA) and polycarbonate (PC) was selected as plastic material which was injected inside the mould. The mould was consisted of two stainless steels and designed based on the actual platen dimension of a plastic injection machine. The horizontal cooling water channels were used for the cooling of the plastic parts. It was found that the cooling time of the PC in plastic injection mouldingwas smaller than those of PMMA material.
