How are ‘Rotomoulded’ water tanks made?

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 […]
