Rotational Moulding is not just a process from the past; it has much to offer current designers looking for flexibility. The range of materials, design options and post-moulding operations available mean that rotomoulding can supply a solution to any short run situation where other processes such as injection moulding would be uneconomic. The addition of inserts and in-mould graphics adds another dimension to the attractiveness of this process. The basic process is outlined, together with comments relating to toolmaking, materials, inserts, design and decoration. To make a part, pre-determined amounts of ground polymer are introduced into a hollow mould which is rotated and heated until the plastic solidifies. After cooling, the part is removed from the tool and the process can begin again. Common materials include polyethylene and polypropylene but nylons can also be found as well as amorphous materials. Tooling is often aluminium. Post-moulding operations are common. Parts are stress free.
