Rotomoulding is a cost-efficient method for medium and small production lines in particular and creates complex geometries for plastic parts as well as basic ones. The parts are manufactured by filling a steel or aluminium mould made up of two or more parts with raw material in powder form. The raw material is heated, then it melts and settles visibly on the sides of the mould – and the wall thickness of the plastic part is built up layer by layer as a result. After controlled cooling, the finished product is removed.
