<p>A rotational moulding process replicates a product by conveying fusible materials of one or more compositions during a moulding procedure through an opening into a heated mould rotating in one axis inside an oven. Large products are feasible. A multi-layered product wall is constructed using for example an optionally dyed exterior and foaming granules in a middle layer. A bell-shaped product capable of conversion into a dwelling is made in this manner inside a metal mould, open at one end and slowly rotating about a horizontal axis in an oven.</p> |
