Building a Plastic Injection Moulding Machine

摘要

During 1976, as part of a Design Technology teacher training course, the construction of a steel mould for plastic injection moulding formed the basis of a practical assignment. The mould that I designed and made was used to produce a series of two and one half inches wide caterpillar track links. It was anticipated that a set of links so formed would provide the tracks for a radio controlled, one metre long model tracked vehicle to be built as a final year practical project.
