Rotational Moulding

Rotational moulding was a common moulding process in 1940, however, it was superseded by other moulding techniques since it was deemed a slow process for small numbers of finished goods. However, the past decade has seen rotational moulding revolutionised, and an upsurge in its use. Also known as BrE moulding, rotational moulding, uses a heated hollow mould which is filled with material and then slowly heated and rotated to allow the material to stick to the mould. Rotocasting is a similar process to rotational moulding but the mould itself is not heated. Spin casting is often confused with rotational moulding but it uses utilising self-curing resins or white metal in a high-speed centrifugal casting machine (not slowly turned). Products manufactured by rotational moulding include storage tanks, furniture, road signs and bollards, planters, pet houses, toys, bins and refuse containers, doll parts, road cones, footballs, helmets, canoes, rowing boats, kayak hulls and playground slides.
