Rotomoulding or rotational moulding is a low pressure, high temperature plastic forming process that uses heat and biaxial rotation (i.e., angular rotation on two axes) to produce hollow, single-piece parts.
Disadvantages are long production cycles —only one or two cycles per hour can typically occur, compared to other processes like injection molding, where parts can be formed in a few seconds. Rotomoulding does have great advantages. Manufacturing big, hollow parts such as water tanks is much easier by rotational molding than any other method. Rotational moulds are significantly cheaper than other types of mould.
Very little plastic material is wasted using rotomoulding for water tanks, and excess material can often be re-used, making it a very economically and environmentally viable manufacturing process.
The rotational molding process consists of 4 basic steps:
