Plastic Injection Mold Set Up Technician

Mold & Machine Setup Perform mold changes on injection molding machines safely and efficiently. Set up and prepare Niigata and Toyo injection molding machines for production. Install and properly secure molds, including connecting water lines, hot runners, hydraulics, and other required connections. Set and verify machine parameters based on setup sheets, work instructions, and established process standards. Set barrel and mold temperatures, injection speeds, pressures, screw speeds, back pressure, cooling time, and other process parameters. Set up and verify auxiliary equipment including dryers, loaders, chillers, temperature controllers, granulators, robots, and material handling equipment. Verify the correct mold, material, color, inserts, and production components before starting a job. Ensure all machine, mold, and auxiliary equipment connections are properly installed before startup. Machine Startup & Process SetupBring injection molding machines from startup to stable production conditions. Purge and prepare machines for production as required. Establish the proper molding process and make adjustments to achieve consistent, quality parts. Run initial samples after mold changes and make necessary process adjustments. Verify that parts meet established quality, dimensional, and appearance requirements before releasing the machine to production. Monitor machine operation during startup and throughout the production run. Ensure machine settings are documented and maintained according to company standards. Troubleshooting Troubleshoot injection molding machines, molds, materials, and auxiliary equipment. Diagnose and correct molding defects including: Short shots FlashSink marks WarpageBurn marks SplayWeld lines Flow marks DiscolorationDimensional variation Part sticking Inconsistent filling Determine whether problems are related to machine settings, mold conditions, material, temperature, cooling, or equipment. Make appropriate process adjustments to correct problems while maintaining part quality and cycle-time requirements. Troubleshoot machine alarms and production interruptions. Identify mechanical, hydraulic, pneumatic, or electrical issues and determine when Maintenance support is required. Work with Maintenance, Quality, Engineering, and Production to resolve recurring problems. Help identify root causes and implement solutions that prevent repeat issues. Production Support Support production operators after setup and ensure they have a properly running process. Respond to machine and process problems throughout the shift. Minimize machine downtime, scrap, and production interruptions. Monitor cycle times and process consistency. Assist with mold changes and job changes as production schedules require. Help maintain efficient production while meeting quality and safety requirements. Communicate machine, mold, material, and process issues to the appropriate Supervisor or Manager. Quality & Documentation Follow setup sheets, process instructions, and documenting setup parameters and process changes.
