A process of moulding thermoplastics, ideal for the production of medium and large hollow items. Typical products suitable for rotational moulding, sometimes called rotomoulding, include tanks and containers, kayaks, garden products and furniture - the list is endless!

As with all processes and materials, it is important to weigh up the advantages against the disadvantages. For the design engineer it is important to have a basic understanding of the parameters of rotomoulding and its limitations. However, this is where the expertise of Rota Design comes in, guiding you through the pitfalls and capitalising on the positive benefits where appropriate.

A great advantage of rotational moulding to consider is the relatively cheap tooling costs especially in comparison to injection and blow moulding. A low initial investment provides an entry point for lower volume production with much faster time to market. Diversity of products and overall production cost in the rotomoulding industry are positive factors which make for many exciting and innovative products.
