Steve Hurst of Johnston Sweepers - Broanmain Plastics customer

“Traditionally, exterior components on our machines were cast from Aluminium. Wilf and the team at Broanmain encouraged us to review this way of thinking, as they were able to offer a range of durable materials and sensible tooling prices. We started several years ago with one component and now have over twenty two components in series production.”
