As part of innovative solutions developed for Australia’s pipeline construction industry, Richmond Wheels and Castors designed and manufactured two polyurethane moulding tools.
Pipe rollers were required for the Gorgon Project in Western Australia. There were several challenges in developing the pipe rollers and an economical polyurethane moulding tool that would allow for multiple polyurethane pours of 100kg each to meet the delivery schedule of the project.
Designing and manufacturing two polyurethane moulding tools out of specially moulded 94A polyurethane, Richmond successfully poured, baked and turned 20 pipe rollers, each weighing 400kg.
Polyurethane moulding tools provide enormous benefits for time-constrained projects as they reduce the manufacturing time as well as cost when compared to traditional steel or aluminium tooling.
Key features of Richmond’s in-house polyurethane moulding tools:
- Polyurethane machine with 2 x 200kg tanks capable of vacuum degassing to eliminate trapped air within the mix
- Ability to constantly pour polyurethane with one tank being filled while the other is in use
- 2-tank design gives the flexibility to machine-pour different materials throughout the day
- Allows for tonnes of material to be processed every day with perfectly mixed, air-free consistency
Four ovens are also provided for curing the polyurethane after pouring, allowing the user to pour and cure up to four different types of polyurethane at the correct curing temperatures.
