High Performance Moulding

Course Description
  • The candidate will be introduced to melt preparation by the selection of correct processing parameters for the type and grade of thermoplastics material being processed during this course.
  • The candidate will understand the importance and technologies related to effective mould temperature control and its relevance to productivity and part quality/dimensional control.
  • The candidate will understand the importance of effective part removal and its relevance to productivity and part quality/dimensional control.
  • The candidate will be introduced to the concepts and methods of achieving the most consistent and economic process cycle for injection moulded components.
  • The candidate will be introduced to pressure/temperature transducer technology.
  • The candidate will use RJG’s PRO-OP™ software during the optimisation exercises.
