Test Specimen Manufacturing

Smithers Rapra has small-scale processing capabilities for both plastics and rubber. Our facilities are commonly used for the manufacture of test samples, but can also be utilized for short production runs and molding of new materials.

We can process most polymers. Our equipment is capable of processing common materials such as polyolefins all the way through to the high temperature engineering plastics such as PES, PPS and PEEK. We also have experience with water soluble polymers and bio-based polymers.

Our core techniques include compounding, extrusion and injection molding - all peformed by an experienced team of polymer technologists. 

Plastic Materials

At our Shawbury, UK laboratory, we can injection mold test bars on our two injection molding machines or compression mold plaques on our processes. These samples can then be taken away for testing or we can test them in our UKAS accredited laboratory.

We can also put lines together to produce blown films or cast film and sheet, coat wire or extrude pipe. Again, these samples can either be taken away for testing or we can assist as required.

Smithers Rapra can also compound the materials prior to shaping so that new additives can be tested.  Ideally, you bring the materials and formulation, and we will do the rest. We can also source the materials, if required.

Rubber Materials

For rubber we can offer a small batch mixing service in both our US and UK laboratories. We can also provide cure information and production of simple test shapes.

Materials Testing

Our laboratories are ISO 17025 accredited and can perform a range of physical and chemical tests on plastics and rubber. The Smithers Rapra team of experts can develop a custom testing program to suit your individual requirements, based on material type and intended end-use.
