Abstract
Injection moulding is one of the most important melt processes for thermoplastics. With PVC, and especially uPVC, its operation is complicated by two factors: the susceptibility of PVC polymers to heat degradation, and their high melt viscosity. These factors can give rise to problems: they necessitate particularly careful control of the thermal input, melt temperature, and pressures in the process. However, in recent years the difficulties have been considerably eased by the development of effective, sophisticated electronic means of process control, and by the advent of ‘easy flow’ uPVC moulding compounds.
