Understanding Injection Moulding of Thermoplastics

Understanding Injection Moulding of Thermoplastics
The key to optimum plastic part design. This conference will be online via MS Teams.
The course focuses on the complex phenomena behind the Injection Molding process with a strong emphasis on the understanding of parts’ problems (aspect, shrinkage, warpage, weld lines, burns, etc.) and their relationship with material properties (amorphous, semi-cystalline, filled, unfilled) and the process itself. Each day different topics will be covered.

25 August
  • Introduction to the process
  • Fundamentals of rheology including pressure dependence of viscosity

26 August
  • Basic fiber orientation
  • Flow in simple geometries
  • Thermal effects and frozen skin dynamics

27 August
  • Cosmetic issues and weldlines
  • Fundamentals of the packing phase

28 August
  • Residual stresses
  • Shrinkage and warpage
  • Conclusions
Seminar Content
  • basic polymer thermal and rheological behaviour
  • effect of pressure on polymer properties
  • the flow process in Injection Molding
  • part geometry and flow pattern
  • compressibility, phase change and PVT data
  • what is crystallinity and how does it affect processing
  • the packing phase: key to the dimensional quality of the part
  • effective part, mould and process design for proper cavity packing
  • understanding the shrinkage build-up
  • part warpage mechanisms: designing for minimum warpage, according to material properties and part shape
  • warpage: the special case of fibre filled materials
  • the concept of residual stresses: the compromise with warpage
  • final conclusions and wrap-up – seminar evaluation by the participants
  • The seminar is not specifically about Injection Molding Simulation. However, the intention is to clearly help those among the participants who are “Flow Analysis users” to gain a thorough understanding of the concepts that form the basis of the existing code. Model assumptions and corresponding limitations will be highlighted and discussed.
