Injection Mold Set Up (Plastic)

Injection molding equipment

Program Overview

New Richmond

Injection molding machine setters set up and tend machines that transform plastic compounds into a wide variety of consumer goods such as toys, tubing and auto parts. They install plastic injection molds on the molding machine; make necessary connections of the electrical, hydraulic and cooling systems to the mold; insure that the correct plastic material, plastic melt temperatures, shot size, injection speed and pressures are set; and cycle the machine and adjust the molding parameters until acceptable parts are produced. 

Units of instruction include electricity, hydraulics and pneumatics; statistical process control; plastic mold design and blueprint reading; technical mathematics; basic tool room machine shop operations; and an overview of many of the plastic molding processes other than injection molding.
