Products & Services
If 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®
We produce cast and injection moulded balls for food processing and general applications.
We are able to offer injection moulded balls in a wide variety of materials for special applications. Materials include nylon, polyethylene, etc. We can also customise balls to suit specific needs. For example: to operate with nylon screens, stainless screens, or with very abrasive particles both wet and dry.More Info
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.More Info
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.More Info
