Job description

Injection Molding Process Technician (1st Shift) Job Description Injection Molding Process Technician (1st Shift)

Your Mission

The Injection Molding Process Technician is responsible for setting up, starting, monitoring, troubleshooting, and optimizing nine injection molding machines. All nine machines are equipped with RJG eDART process monitoring systems and utilize cavity pressure for transfer from injection (fill) to pack/hold.

This position is responsible for maintaining stable, repeatable molding processes using cavity pressure data, ensuring consistent part quality, minimizing downtime and scrap, and achieving production targets. The technician must be proficient in interpreting cavity pressure curves, monitoring process limits, troubleshooting molding defects, and maintaining approved process parameters.

The successful candidate will take ownership of the assigned molding area, ensuring all nine machines operate safely, efficiently, and consistently while meeting quality requirements and production schedules.

How you will make a difference

A. Machine Setup and Process Control

• Set up, start, adjust, and optimize injection molding machines according to approved setup sheets and process specifications.
• Perform mold changes, material changes, color changes, and production changeovers.
• Establish and maintain approved process parameters, including injection speed, pressure, barrel temperatures, mold temperatures, cooling time, pack/hold settings, and cycle time.
• Set up and verify cavity-pressure-based transfer from injection to pack/hold according to established process requirements.
• Ensure transfer is controlled by the approved cavity pressure setpoint or pressure-based transfer criteria rather than relying solely on screw position or elapsed time.

B. RJG eDART and Cavity Pressure Process Monitoring

• Operate, monitor, and troubleshoot RJG eDART process monitoring systems installed on all nine injection molding machines.
• Interpret cavity pressure curves to evaluate process stability, transfer performance, packing behavior, and overall molding consistency.
• Monitor cavity pressure at transfer, peak cavity pressure, pressure rise, curve shape, and other established process indicators.
• Verify that cavity pressure-based transfer is functioning correctly and consistently on each machine.
• Monitor eDART alarms, process limits, and out-of-specification conditions and respond according to established procedures.
• Identify abnormal pressure profiles and investigate potential causes, including material variation, mold conditions, blocked or damaged sensors, machine performance, and process settings.
• Recognize changes in cavity pressure signatures that may indicate short shots, flash, dimensional variation, sink, warpage, or other quality concerns.
• Verify that cavity pressure sensors and monitoring channels are functioning properly and that the correct signals are associated with the applicable mold cavities.

C. Troubleshooting and Process Optimization

• Identify and correct molding defects, including short shots, flash, sink marks, warpage, burn marks, splay, contamination, and dimensional defects.
• Troubleshoot machine, mold, material, auxiliary equipment, and process-related problems.
• Use cavity pressure profiles and eDART data to determine whether process abnormalities originate from the machine, mold, material, sensors, or process settings.
• Optimize cycle times while maintaining approved cavity pressure profiles and part quality.

D. Production Oversight

• Maintain awareness of production status, cycle times, machine performance, and job priorities across all nine machines.
• Prioritize machine checks and troubleshooting based on production needs, alarms, process deviations, and quality risks.
• Monitor machine alarms, cycle interruptions, downtime, and production rates.
• Respond promptly to machine stoppages, eDART alarms, process deviations, and quality concerns.

E. Quality Assurance

• Ensure molded parts meet established dimensional, visual, and functional requirements.
• Perform or support first-piece inspections and required in-process quality checks.
• Verify that the correct resin, colorant, mold, and approved process specifications are being used.

F. Materials and Auxiliary Equipment

• Verify material requirements before production begins.
• Ensure proper resin drying, handling, blending, and loading according to material specifications.
• Monitor dryers, material loaders, temperature controllers, mold temperature units, water lines, and other auxiliary equipment.

What you should be good at

• High school diploma or GED required; technical training in plastics processing or manufacturing preferred.
• Minimum of three years of injection molding experience preferred, including machine setup, processing, and troubleshooting.
• Demonstrated ability to independently set up, process, and troubleshoot injection molding machines.
• Hands-on experience with RJG eDART systems and cavity pressure monitoring required.
• Demonstrated understanding of cavity-pressure-based transfer from injection to pack/hold required.
• Ability to interpret cavity pressure curves and identify process deviations.
• Knowledge of injection molding defects, process variables, and corrective actions.
• Experience with mold changes, resin changes, dryers, material loaders, temperature controllers, and auxiliary equipment.
• Ability to read and follow setup sheets, work instructions, control plans, and quality specifications.
• Basic computer skills for process documentation, production reporting, and data review.
• Strong mechanical aptitude, troubleshooting ability, attention to detail, and problem-solving skills.
• Ability to manage priorities and respond effectively to issues across nine machines.
• Ability to work independently while communicating effectively with production and support teams.
