Custom / Contract Moulding

From concept to production, we deliver custom rotational moulding solutions.

For over 40 years, Rota Moulding has worked with customers to develop production-grade polyethylene products, from initial concepts and CAD files through to tooling and full-scale manufacturing.

All work is completed locally at our Midvale facility, providing greater control, flexibility and responsiveness.

Frequently Asked Questions

Yes. We regularly work from initial concepts, sketches and reference ideas, as well as detailed drawings and CAD files. We can assist in developing these into production-ready moulded products.

Yes. We can support design development, including CAD modelling and refinement to ensure the product is suitable for rotational moulding and end-use performance.

Minimum order quantities vary depending on the product and tooling requirements. We typically support low to medium production runs and can advise based on your specific application.

Timeframes vary depending on complexity, tooling and production requirements. A typical project may range from several weeks for development and tooling through to ongoing production once established.

Yes. Prototyping and initial production runs are often used to validate design, fit and performance before moving to full production.

We primarily use UV stabilised polyethylene (several grades and specs available), selected for its durability, chemical resistance and suitability for a wide range of applications.

Yes. We offer contract manufacturing where customers supply their own tooling and we produce to specification.

No. We specialise in rotational moulding, which uses moulds to produce consistent, durable products rather than fabricated plastic assemblies.
