Rotational moulding is one of the most versatile plastic manufacturing methods, much enhanced by the range of specialist polyethylene and polypropylene materials available. Rotational moulding has the creativity, the productivity, the quality, the simplicity, and the professional standards that are required in product design and production. Simple in concept, rotational moulding is considered by those in the industry to be as much an art as a science in view of the importance of human judgement in the quality of the finished product.
