Plastic Part Failure Analysis

 

Look at failures in plastic products and their prevention from the standpoint of the fundamentals of part design, mold design, material selection, processing, and product testing and validation. Discuss the importance of each of these areas. Review the tools used to conduct failure analysis with an emphasis on practical application and a standard approach to methodology. Case studies are provided as illustrations of how these principles and tools are applied.

Elements of a Successful Plastic Product

  • Part design
  • Mold design
  • Material selection
  • Processing

Principles of Plastic Part Design

  • Nominal walls
  • Ribs and other projections
  • Holes and other depressions
  • Designing for manufacturing and assembly (DFMA)
  • Design properties versus inherent properties of materials

Mold Design Considerations

  • Mold steel selection
  • Managing polymer flow in the mold – runners and gates
  • Cavitation and the effect on balanced flow
  • The economics of cavitation
  • Hot runners versus conventional cold runners
  • Mold temperature control
  • Draft angles and ejection

Material Selection

  • Defining the application environment – time, temperature, stresses
  • Amorphous and semi-crystalline polymers
  • The importance of molecular weight
  • Structural choices within a polymer family
  • Property modifiers and additives
  • Regulatory considerations – UL, NSF, FDA
