Rotational Moulding

Learn more about rotational moulding

Rotational moulding is a manufacturing process used primarily to create seamless, stress-free, hollow products.

Additional processes can be added; for example filling with polyurethane foam or epoxy filler. Rotational moulding offers the opportunity to manufacture stress-free parts with uniform wall thickness and complex shapes at a relatively low production cost.

Moulds are first filled with small plastic pellets. The mould is then heated and rotated, using centrifugal force to coat the inner walls of the moulds with plastic. No additional pressure is required during the casting.
