Engineering Plastics

Engineering PlasticsIf there is an industrial application for specialised plastics then James Walker has probably made a product for it.

We produce hydraulic and pneumatic seals, diaphragms, hot cast polyurethane components, spin cast and high volume injection mouldings.

These products, which range in size from as little as 10mm diameter to in excess of 2500mm with individual components weighing up to 1000kg,  are used in a wide range of industries from food and drink to railways, power generation and subsea oil and gas.

Whatever the application we are able to provide the ideal material for the job including our own range of high-specification proprietary Devlon®

Custom Moulding Engineered Plastics

We custom mould components in a wide range of engineering plastics using the latest techniques and equipment.

Utilising a 3 component  hot cast polyurethane system offering high hydrolysis resistance, high  abrasion resistance and good mechanical properties.

  • Hardness available from 60° Shore A to 60° Shore D
  • Any colour supplied to order
  • Applications include Tube Test Seals, Rollers, couplings, wear parts, scraper blades and general castings

Food Quality Products

We manufacture numerous precision components for the food processing and beverage sectors.

Standard and custom-designed components manufactured in polyurethane and numerous thermoplastics. Many of the plastic Materials are compliant with Water Regulations Advisory Scheme (WRAS) and Food and Drug Administration (FDA) standards and therefore suitable for use in bottling, canning and food handling equipment.

High Specification Engineering Plastics

Our Devlon® materials are amongst the toughest and hardest-wearing thermoplastics. By monomer casting and machining to exacting specifications, we produce complex components from 10mm to over 2500mm OD, and weighing up to 1000kg.

  • Resistant to impact and shock loading
  • Zero corrosion; resistant to water absorption and mould growth
  • Low friction
  • One-sixth the weight of bronze
  • Exceptional resistance to wear and abrasion
  • Extensive cost savings

Our Devlon V-API grade can now be instantly identified as authentic material through the use of James Walker Positive Material Identification Technology, protecting our customers from the risks of using lower-performance imitation materials.
