If very good deformation resistance is not required a thermoplastic material such as SBS or Hytrel can be used. These materials are formed by heating processes, normally injection moulding or extrusion . Before you go you should see our comparison table to confirm your choice. If you are not sure how a process works click on that plastics process and we will show you how it works, and give further examples. Extrusion - Extrusion is used to make continuous sections only.
Parts can however be slit, cut, drilled as secondary operation.
Materials are generally thermosetting type materials such as epoxy. Chemically curing resins are injected at very low pressures,or drawn into a mould under a vacuum. Long cure times mean that this is an expensive production process. Limitation of high tooling cost for most applications. Parts are formed by injecting soft or liquid material into a complete mould under very high pressures.
