Abstract

In a rotational moulding apparatus the mould, on support means (not shown), is located in a heating chamber 1 below spraying heads 12 supplied by a pump 7 from a tank 2 containing a liquid or liquefiable solid heating medium e.g. a liquefiable eutectic salt, the supply circuit including a heat exchanger 9 and valves 11 and 13. An air heater 3 supplies, under the control of valves 5, the conduits 4 to heat the material in the tank 2 and supply and return conduits to the heating chamber 1. The valves 11 and 13 may be electrically controlled so that one is open when the other is closed. The output of the heat exchanger 9 may be controlled in dependence of the temperature of the liquid in pipe 10 and the pump 7 may be controlled not to operate if the heat exchanger 9 is not adequately heated.
