Syllabus

 

Day 1

  • Introduction to Scientific Processing and Scientific Molding
  • Challenges in Injection Molding Process Development
  • Required basics of Polymer Morphology, the PVT diagram, Data Sheets
  • The 11+2 Inputs and 10 Output of an Injection Molding Process
  • Process Development 1: Scientific Molding
  • Melt Preparation
  • The 6-Step Study
  • Process developed after the SIM studies
  • Challenges with the process developed by SIM only

 

Day 2

  • Process Development 2: Design of Experiments (DOE)
  • What is a DOE?
  • History of DOEs
  • Is SIM the same as DOE?
  • The theory and Basics of DOE
  • Types of Experimental Designs
  • Orthogonal Arrays
  • Interactions
  • Confounding and Aliasing of factors

 

Additional Topics Covered

  • Factor Selection for Injection Molding
  • Tornado Charts, Main Effect Plots,
  • Use of Software for Analysis
  • Using DOE analysis in production for reducing inspection, improving part quality, reducing scrap
  • Measurement Sample Collection, replicates
  • Randomization
  • ANOVA, choosing meaningful Highs and Lows
  • ‘Bad Data’: Garbage In, Garbage Out!
  • Challenges in measurements in multicavity molds
  • Reducing inspection of DOE samples
  • Simple Plan to get started with DOEs


Note: This is a hands-on class where we will be performing experiments at the molding machine, measuring parts and analyzing the results.
