Plastic Part Failure Analysis

Fee: $1,095
Instructor: Mike Sepe

Who Should Attend:

Product designers, molders, and mold designers can benefit from this two-day seminar. Engineering and training managers can also benefit from a better appreciation of the characteristics of plastic part quality and performance. Buyers can gain an understanding of the importance of designer and quality specifications.

Course Outline:

Elements of a successful plastic product
1. Part design
2. Mold design
3. Material selection
4. Processing
Principles of plastic part design
1. Nominal walls
2. Ribs and other projections
3. Holes and other depressions
4. Designing for manufacturing and assembly (DFMA)
5. Design properties versus inherent properties of materials
Mold design considerations
1. Mold steel selection
2. Managing polymer flow in the mold - runners and gates
3. Cavitation and the effect on balanced flow
4. The economics of cavitation
5. Hot runners versus conventional cold runners
6. Mold temperature control
7. Draft angles and ejection
Material selection
1. Defining the application environment - time, temperature, stresses, etc.
2. Amorphous and semi-crystalline polymers
3. The importance of molecular weight
4. Structural choices within a polymer family
5. Property modifiers and additives
6. Regulatory considerations - UL, NSF, FDA
7. Performance and processability
8. Establishing the cost/performance balance
Processing
1. The fundamentals of polymer flow
2. The effect of material structure on sound processing decisions
3. Machine selection
4. Process control strategies
5. The quest for Six Sigma
Failure analysis tools
1. Material testing - composition and degradation
  1. Molecular weight evaluations
  2. Thermal analysis - DSC, TGA, DMA, TMA
  3. Spectroscopy - FTIR, EDS, XPS, SIMS
2. Microscopy - cross sections and scanning electron microscopy
3. Physical property evaluation - your part is not a tensile bar
4. FEA and its relation to the application environment
5. Advanced characterization of mechanical properties
The failure analysis process
1. Gathering background information
2. Focusing on the four fundamentals of a successful product
3. Conducting the appropriate evaluations
4. Establishing root cause
5. Fixing what is broken
6. Understanding the interactions of multiple causes
7. The role of designs of experiment
8. The cost/benefit analysis of problem solving
9. Following up
Case studies
