Abstract

A method for moulding of thermoplastic materials in particular so as to improve on the part quality by eliminating defects such as weld-lines, etc. The method involves rapidly heating a mould cavity 612 to a predetermined temperature using hot dehumidified air (via heating line route 604), followed by application of vacuum over the mould cavity so that the moulding material is held rapidly towards the mould before application of super-cold water (via cooling line 608) for the rapid cooling of the moulded article. It comprises of a standard conventional injection moulding machine, a tool (or mould) and a separate, independent, external self-contained control system which may be readily attached to and removed from the moulding machine, the tool (or mould) as well as any other auxiliary equipment needed for the injection moulding process. The tool or mould could be either standard cavity mould or multiple cavities mould moving in a sequential motion or injection-compression moulding.
