Micro-injection moulding

The research characterisation of micro scale polymer flow behaviour at the melt/tool interface using rapid tooling and novel condition monitoring techniques. This includes:

  • characterisation of demoulding and studies on the influence of injection and cavity pressure on the demoulding force in micro-injection moulding.
  • manufacturing routes for replicating micro and nano surface structures with bio-mimetic applications, and applying novel diamond like carbon surface structuring for micro injection mould masters.
  • investigating rapid tooling solutions for micro lens prototypes, and soft tooling for producing small series of polymer micro parts.

Research focus

The main focus of this research is in:

  • micro-injection moulding.
  • tooling.
  • process factors.
  • potential uses of Bulk Metallic Glass (BMG) materials in micro injection moulding.
  • gas compression and air evacuation in high speed polymer melt transfer.
  • the behaviour of polymer melts including the slip stick phenomena over highly polished and rough engineered surfaces.
  • the application of direct piezo pressure measurement in micro cavities.
