The Advantages of Polyurethane

Polyurethane is ideal for the cost effective creation of tough, rigid, structural mouldings without the high start-up costs of traditional plastic injection moulding processes.

Why Choose Polyurethane?

  • Tough, Rigid Mouldings
  • Cost-Effective Low-Volume Production
  • Excellent Strength-to-Weight Ratio
  • Design Flexibility
  • Durable and Long-Lasting
  • Customisable Finishes

What is it?

Our Polyurethane is a rigid self-skinning expanded foam system specifically blended to produce tough rigid and structural mouldings to a high specification.

What is it good for?

Low-run batch quantities of mouldings for electronics enclosures and devices that benefit from varying wall sections from 1 – 40mm locally that can create an integral chassis in conjunction with strength and aesthetics. It is an excellent material for handheld devices or those requiring the benefits of the material’s excellent insulation properties or buoyancy.

What is the Process?

Reactive Injection Moulding (RIM) – a injected reactive mixture of polyol resin with a curing agent into a closed aluminium mould . The mixture rapidly expands forcing air from the tool and filling the cavity with a rigid, structural foam that has a hard skin and softer inner molecular core with an average density of 600 kg/m3.

Why is it Cost Effective?

Aluminium Tooling is a fraction of the cost of plastic injection mould tools with the benefit that start-up costs and modifications are considerably cheaper with short lead times.

If your requirements are 20-1,500 units per annum and your project has a high intrinsic value this process is ideal for your project.

Mouldings are exceptionally durable and can last decades. Its strength and rigidity mean far fewer breakages than other similar processes.
