Engineering Technician: Injection Molding

Job Description

Core Responsibilities

Advanced Injection Molding Diagnostics & Technical Problem Solving

• Serve as a primary technical escalation point for complex, chronic, or high-impact injection molding problems beyond standard production troubleshooting and routine process adjustments.
• Independently diagnose manufacturing problems across Process, Machine, Mold, Material, Controls, Automation, auxiliary equipment, and operating practices, including interactions between these systems.
• Analyze molding parameters, machine and process data, alarm histories, equipment behavior, production trends, and product defects to isolate technical failure modes and sources of manufacturing variation.
• Lead structured root cause investigations, develop evidence-based conclusions and corrective-action recommendations, and coordinate Engineering, Maintenance, Automation, Quality, and other specialized resources when required.
• Verify corrective-action effectiveness through process capability, quality, equipment, and sustained production results, emphasizing elimination of systemic causes rather than repeated correction of symptoms.

Scientific Molding & Advanced Process Analysis

• Apply advanced scientific molding principles to troubleshoot, develop, evaluate, and optimize injection molding processes and establish robust, repeatable processing windows.
• Execute and interpret advanced molding studies including fill, pressure-loss, gate-seal, viscosity, cooling, process-window, capability, and other structured technical studies.
• Analyze relationships between machine settings, actual process conditions, material behavior, mold performance, environmental conditions, automation, and finished-product quality.
• Apply statistical methods, process capability analysis, structured trials, and Design of Experiments (DOE), where applicable, to identify significant variables and develop technically supported recommendations.
• Optimize molding processes to improve cycle time, scrap, uptime, productivity, capability, and OEE while maintaining established safety, quality, and process-control requirements.

Molding Machine, Controls & Automation Diagnostics

• Utilize molding-machine controls, HMI diagnostics, alarm histories, process-monitoring systems, and manufacturing data to diagnose complex process and equipment abnormalities.
• Diagnose interactions among molding machines, molds, hot runner systems, auxiliary equipment, material-handling systems, automation, robotics, and downstream processes.
• Analyze PLC/HMI diagnostic information, sensors, I/O status, alarms, interlocks, machine sequences, and equipment feedback to distinguish process issues from controls, automation, electrical, or mechanical problems.
• Read and interpret technical drawings, mold documentation, control diagrams, electrical schematics, process specifications, and equipment documentation required for advanced diagnostics.
• Provide Engineering, Machine Maintenance, Mold Maintenance, and Automation teams with technical evidence and execute process verification and stabilization following repairs, modifications, controls changes, or significant maintenance events.

Qualification, Validation & Manufacturing Readiness

• Execute technical qualification and validation activities for injection molds, molding processes, equipment, materials, and associated manufacturing systems through structured studies, trials, data analysis, and capability evaluations.
• Evaluate mold and process performance following repairs, engineering modifications, transfers, equipment changes, and new production launches, identifying risks to stable and capable manufacturing.
• Execute technical test plans and validation protocols, analyze results against established acceptance criteria, and document findings, manufacturing risks, process capability, and recommendations.
• Support equipment commissioning, installation, startup, production acceptance, and manufacturing readiness, including participation in FAT/SAT activities where applicable.
• Evaluate and verify process capability and stability during production ramp-up and new product introduction using objective manufacturing data to confirm repeatable operation within approved processing windows and quality requirements.

Manufacturing Data, Technical Leadership & Continuous Improvement

• Analyze real-time and historical process, equipment, quality, cycle-time, downtime, scrap, capability, and OEE data to identify abnormal conditions, recurring failure modes, and technical relationships not evident through routine troubleshooting.
• Translate complex manufacturing information into documented technical findings, recommendations, corrective actions, and data-driven diagnostic or monitoring methods that support process optimization and prevention of manufacturing losses.
• Serve as an advanced injection molding technical resource for Process Technicians, Setters, Operators, Maintenance Technicians, Production Teams, and cross-functional technical partners.
• Provide technical direction and coaching in scientific molding, structured troubleshooting, process controls, root cause analysis, manufacturing data interpretation, and disciplined technical problem solving.
• Develop and improve troubleshooting standards, diagnostic methodologies, technical documentation, process-control practices, and injection molding best practices while supporting knowledge transfer and continuous improvement across local and global molding organizations.

Experience

• Minimum 5 years of progressively advanced technical experience in injection molding within a high-volume manufacturing environment, including responsibilities beyond routine machine setup, process adjustment, and standard production troubleshooting.
• Demonstrated advanced expertise in scientific molding, injection molding process development, complex diagnostics, process optimization, and establishment or evaluation of robust processing windows.
• Demonstrated experience independently executing advanced molding studies, technical trials, structured root cause investigations, process capability evaluations, and qualification or validation activities.
• Advanced understanding of interactions among molding machines, molds, materials, hot runner systems, process parameters, auxiliary equipment, controls, automation, and product quality, including the ability to diagnose multi-system manufacturing problems.
• Experience supporting mold qualifications, process validations, equipment commissioning/startups, production launches, manufacturing-readiness activities, and technical corrective actions while independently organizing complex technical investigations and engaging cross-functional resources.

Education & Technical Training

• Associate degree, technical diploma, apprenticeship, military technical training, recognized technical certification, or equivalent combination of technical education, training, and directly relevant advanced injection molding experience.
• Technical education or training in plastics technology, injection molding, manufacturing engineering technology, mechatronics, industrial technology, automation, controls, tooling, or a related technical discipline is preferred.
• Advanced Scientific Molding, RJG, AIM, Paulson, or equivalent injection molding training or certification is preferred.
• Technical training in industrial controls, automation, mechatronics, PLC-controlled equipment, robotics, or industrial electronics is preferred.
• A bachelor's degree in Engineering is not required.

Knowledge, Skills & Abilities

• Advanced technical knowledge of injection molding processes, scientific molding principles, process capability, process variation, and manufacturing stability.
• Advanced analytical and diagnostic capability with the ability to independently investigate complex interactions among Process, Machine, Mold, Material, Controls, Automation, and operational factors.
• Ability to execute and interpret advanced molding studies, technical trials, capability evaluations, qualification and validation activities, and manufacturing data analysis.
• Working technical knowledge of molding-machine controls and automated manufacturing systems, including PLC/HMI diagnostics, sensors, I/O, alarms, interlocks, machine sequencing, and applicable technical drawings and documentation.
• Strong technical leadership, communication, documentation, and coaching capability with the ability to translate complex technical findings into actionable recommendations and work effectively across Operations, Engineering, Maintenance, Automation, and Quality.
