Use of Automation in Injection Molding Case Study
A manufacturer of Portable Test Kits and Instruments to detect and quantify contaminants in soil, water and oil required a new Breakaway Cap for use in the field. To find a find a solution J&L Plastic Molding developed automation to improve the injection molding process.

De-Gating
To De-Gate the parts from the runner system, J&L uses end-of-arm robotics to pick the runner system and parts from the mold. The end-of-arm robotics then positions the runner system and parts to a cutting fixture to separate the parts from the runner system.
