Lesson 2: Design Types

In the first lesson of this section, you learned the five stages of conducting a DOE strategy and how to use various charts and graphs to analyze experimental data. In this lesson you will learn about several design types and how they can be applied to DOE. Understanding the theory and framework of establishing a DOE strategy is an important skill for part designers, mold designers, and molders.

In this lesson you will learn: the definition of a full-factorial designed experiment; how to use tree diagrams and tables to visualize full-factorial designs; a basic overview of the Taguchi method and how it can be used to maintain a reasonable number of unique molding tests; how to set up and analyze a designed experiment using an injection molding DOE software package; and how to analyze graphical outputs.

Goals of DOE (Level 2): 

  • Learn the theory and framework of establishing a DOE strategy and how to apply this knowledge to real-world molding examples
  • Learn the five stages of conducting a DOE strategy and how to utilize various charts and graphs to analyze the data
  • Learn about several design types and how they can be applied to DOE

Section Description: 

Design of Experiments, or DOE, is a powerful mathematical tool that can be successfully applied to new mold trials and troubleshooting potentially challenging processes. Anyone with a fundamental understanding of injection molding can utilize experimental design techniques. This section covers the fundamentals of DOE and how to apply a DOE strategy for molding quality parts.

Recommendation: Expert-Level Operators, Technicians, & Designers
