Advances in Near Net Shape Polymer Manufacturing Through Microcellular Injection Moulding

  • Chapter
  • First Online:
Near Net Shape Manufacturing Processes

Part of the book series: Materials Forming, Machining and Tribology ((MFMT))

Abstract

Injection moulding (IM) is a well-established manufacturing process for cost-effective replication of polymer-based components. Advanced IM processes have been developed; modifying the final polymer part produced to create microcellular structures. Through the creation of microcellular materials, not only can the final weight be reduced but also, the near net shape can be improved. Microcellular Injection Moulding (MIM) shows high potential to improve near net shape of polymer parts and, the green aspect of polymer manufacturing platforms. This chapter aims to present the significant developments that have been achieved to enhance the MIM technology. Aspects covered include co-injection moulding, core back processing, gas counter pressure, vario-thermal moulding and mould coating. The resulting characteristics of each enhancing technique is presented.
