Rota Moulding is a proudly Western Australian business based in Midvale, specialising in high-quality rotational moulding solutions, predominantly polyethylene (plastic) tanks.
With a team of 10 skilled staff, we manufacture durable polyethylene products for private, commercial, and government customers across Australia.
Founded in 1985, Rota Moulding was one of the early pioneers of rotational moulding in Western Australia.
Rota Moulding is now led by Colby Hauser, who brings a hands-on, growth-focused approach to the business, with a commitment to strengthening customer relationships, improving capability, and investing in the future of local manufacturing.
Rota Moulding has long been an active supporter of the Western Australian community.
For over a decade, we have sponsored cycling clubs and events, supplying water tanks and equipment to support riders and trail development across the state. We are also proud supporters of the Starlight Children’s Foundation, contributing to the incredible work they do to brighten the lives of sick children and their families.
We are committed to responsible manufacturing and reducing environmental impact.
Our products are built to last, with a typical lifespan of 25+ years. We also operate a recycling program to ensure unused materials and production offcuts are reprocessed locally in Western Australia. By using high-grade, clean polyethylene, we ensure that waste is minimised and valuable materials are kept in circulation.
