Thermoset Moulding

Complex specialist precision mouldings.


Often used to facilitate production of metal replacement components. We are able to produce high strength complex objects which are commonly used for electrical switches and connectors.


Components can be made accurately with thicker sections with minimal internal stresses giving superb strength and stability.

Thermoset Injection Moulding

Thermoset, or thermosetting, plastics are synthetic materials that strengthen during being heated that cannot be successfully re-moulded or reheated after their initial heat-forming unlike thermoplastics. Therefore thermosetting plastics have a number of advantages.


  • High surface leaking resistance (Insulation)
  • Excellent mechanical resistance
  • Excellent strength retention even under high temperatures
  • Weather resistance
  • Fire resistance
  • Good impact resistance

These attributes make thermoset ideal for producing electrical connectors, an area that AMS specialise in. We are able to offer extremely accurate tightly tolerance injection moulded electrical connectors including insert moulding of complex electrical contact surfaces.


Additionally, thermosetting moulding compounds due to its irreversible cross-linking chemical process after curing lends itself to high temperature components for producing vehicle engine components such as turbocharger housings which previously have been made out of metal.
