Injection Molding Process Technician

Injection Molding Set up and Operation

• Set up, start, operate, stop, and monitor injection molding machines in accordance with approved setup sheets, work instructions, production schedules, and safety requirements.
• Verify the correct preparation of molds, raw materials, robots, dryers, temperature controllers, material handling systems, label-feeding systems, and other auxiliary equipment.
• Load and verify approved machine recipes and process parameters.
• Conduct production startups following mold, material, label, product, color, or recipe changes.
• Confirm that machine safety devices, mold protection settings, process conditions, and auxiliary equipment are functioning correctly before releasing the line for production.

• Monitor process parameters, machine performance, cycle time, output, scrap, and process stability.
• Adjust process parameters within approved operating limits to maintain product quality and production performance.
• Identify process drift, abnormal machine behavior, and recurring process deviations.
• Record relevant parameter changes and escalation any adjustment required outside the approved process window.

• Perform or support mold, material, label, color, and product changeovers in accordance with approved procedures.
• Verify mold identification, utility connections, line clearance, material preparation, machine recipe, robot program, label setup, and auxiliary equipment configuration.
• Conduct startup trials and restore stable production within approved conditions.
• Obtain the required Quality approval before regular production release.

• Diagnose and correct common injection molding defects affecting product appearance, dimensions, fit, sealing, functionality, and cavity-to-cavity consistency.
• Identify defects such as incomplete filling, flash, deformation, dimensional variation, gate defects, ejection marks, contamination, and recurring cavity-related variation.
• Identify IML defects, including missing, incorrect, doubled, misaligned, folded, damaged, poorly adhered, or visually non-conforming labels.
• Troubleshoot issues involving material feeding, process parameters, hot-runner performance, cooling, ejection, robotic handling, label feeding, positioning, static charging, presence detection, and cycle synchronization.
• Determine whether the probable cause is related to the process, material, mold, machine, robot, automation, label, or operating method.
• Restore stable production when the issue is within the position's training and authorization.
• Escalate complex process, equipment, tooling, automation, or quality issues to the appropriate technical function.

• Conduct routine inspections of machines, molds, robots, label systems, and auxiliary equipment.
• Perform cleaning, lubrication, basic adjustments, and approved autonomous maintenance activities.
• Identify abnormal noise, vibration, leakage, temperature, wear, alarms, or equipment behavior.
• Support preventive maintenance and technical interventions.
• Do not perform specialized electrical, hydraulic, pneumatic, mechanical, automation, or tooling repairs unless trained and authorized.

• Act as the primary injection molding technical resource during the assigned shift.
• Respond to startups, process interruptions, product defects, changeovers, and production instability.
• Determine whether production may continue, requires adjustment, must be placed on hold, or must be escalated.
• Provide a complete technical handover to the incoming shift.
• Support and coach Injection Molding Operators in machine operation, quality checks, process discipline, and standard procedures.

• High school diploma or equivalent required.
• Technical education in plastics processing, injection molding, mechatronics, maintenance, or manufacturing is preferred.
• At least two to three years of hands-on injection molding experience preferred.
• Practical experience in machine setup, production startup, process adjustment, troubleshooting, and defect resolution.
• Experience with mold changes, robots, auxiliary equipment, and IML systems is valued.
• Ability to work independently as the primary injection molding technical resource during the assigned shift.
• Basic computer skills for production, process, quality, and maintenance-support records.
• Ability to complete the company's technical training and internal qualification program.
