Maintenance roles in injection molding involve inspecting, troubleshooting, and repairing hydraulic, mechanical, and electrical systems on molding presses and tooling. Responsibilities split into machine upkeep, mold care, and scheduled preventive tasks to minimize costly production downtime.

Machine Maintenance Responsibilities
