Course Title: Advanced Injection Mold Design

10 Professional Development Hours/1.0 CEUs

Course Description: The Advanced Injection Mold Design course begins by comparing the many different types of materials that are typically used in plastic injection molds. This course goes on to discuss the alloy properties necessary in injection molds, such as harshness, durability, machinability, and polishability. In addition, the course covers the different machining methods such as Electrical Discharge Machining (EDM), or Diffused Discharged Machining (DDM), and others. Finally, the course highlights the many surface treatments available today that a mold builder and/or molder may take advantage of to fight against increased wear and tear on the injection mold.

Overall Course Objectives:

Increase knowledge on tool steels and alloy properties.
Develop an understanding on types of machining (mechanical and electrical) methods.
Recognize the different mold coatings used to protect mold surfaces.
