Day 1: Injection Molding & GD&T Fundamentals

Describe the injection molding cycle and the function of key mold components (core, cavity, runners, gates).

Compare key automotive thermoplastics (PP, ABS, PC/ABS, PA6) based on mechanical, thermal, and chemical properties.

Identify common injection molding defects (weld lines, short shots, warpage, sink marks) and their root causes.

Apply golden rules for part design, including draft angles for textured surfaces and rib-to-wall thickness ratios.

Select an appropriate gate type and location for a given automotive part geometry.

Define datums and establish a datum reference frame (A-B-C) for a simple part.

Interpret and apply position tolerance to a feature pattern and profile of a surface tolerance to a curved feature.

Describe how a 2D drawing with GD&T callouts is created and how design data is structured in a PLM system.
