Abstract:

The physical and mechanical properties of injection moulded thermoplastic mouldings depend on the moulding conditions employed. Some of the variables to be considered are barrel temperature, barrel residence time, injection speed, size and position of gate, mould temperature and the use of regrind material. The effect of these variables on the properties of two materials, polysulphone and polyethylene terephthalate, has been measured and the most suitable moulding conditions established. Polysulphone has been shown to be tolerant to a wide range of moulding conditions but polyethylene terephthalate needs much more care. Author
