Hot compression moulding is one of the better techniques employed to make zero defect products. This paper mainly discusses about the conversion of a conventional hydraulic press into a high pressure, high temperature compression moulding unit at a low cost using local state of the art methodology. A normal press used for blanking, drawing and various metal forming operations is modified here by addition of top and bottom platens with heating coils controlled by PID controllers to operate up to 500°c within which high Temperature Plastics, Aluminium, Tin, Lead, Magnesium etc. can be hot compacted with foil films and reinforcements or can be hot forged with matching dies. In this paper, hot compression moulding as a sound technique for manufacturing zero defect thermoplastic and advanced thermoplastic based composites is demonstrated and emphasized based on a defect evaluation of the moulded parts using an ultrasound scanning technique.
