ENERGY SAVINGS BY THE USE OF GAS ASSISTED INJECTION MOULDING

摘要

The potential for energy savings in by the use of gas-assisted injection moulding is examined.Data are presented from two industrial moulds,one internal,and the other external gas-assisted.In addition,data from a laboratory internal gas-assisted mould are also examined. It is concluded that energy savings on a per-part basis may be realised by the use of gas-assisted injection moulding,however savings in cycle time and material may outweigh the energy savings.
