Rapid heating injection moulding: An experimental surface temperature study

Rapid heat cycle moulding (RHCM) is a recent set of injection technologies that allow a full temperature control in a mould.Between all technologies available in terms of heating and cooling, electrical resistance heating and water cooling were chosen for this study.The mould design has a capital im...
