Injection moulding

The injection-moulding process is described as follows: a thermoplastic in the form of granules or powder passes from a feed hopper into a barrel, where it is heated until it softens. It is then forced through a nozzle into a relatively cold mould, which is then clamped tightly closed. When the plastic has had sufficient time to solidify, the mould opens, the article is ejected, and the cycle is repeated [35].1
