Polyurethane Moulding Process

The Polyurethane Moulding Process

We process polyurethane using the two principal methods of open pour casting and closed injection moulding. Each process has key benefits depending on order volumes, product complexity and the required physical properties of the component’s end use.

This production flexibility means that we are best placed to provide our customer with the best solution whether producing high volumes or single run bespoke items.

Our in-house precision engineering unit offers the capability to design and manufacture unique open and closed mould tools to meet all product requirements.  Our mould tools are manufactured from durable alloys to ensure they produce quality products every time over many years of service.

The Product Produced

We have produced many custom products to match customer requirement.  Our most common products include:

  • Wheels
  • Buffers
  • Coatings
  • Rings
  • Rods
  • Sheets
Polyurethane Materials

Polyurethane Moulding Materials

We manufacture bespoke products using a range of elastomer based polyurethane systems each with a specific chemical formulation depending on the required application and service environment of the end component. Our systems include both MDI and TDI Isocyanates, Polyester and Polyether Polyols.

Our processing equipment has the capability of varying the hardness of our materials anywhere within the range of 50 Shore A to 80 Shore D, and colours can be specified to suit the customer requirements, with commonly specified colours being: Black, Red, Yellow, Green, Orange and Blue.

The polyurethane materials we use in our casting and moulding processes are sourced from the industry’s leading suppliers and are supplied to us having been tested and approved to the highest standards.
