A useful injection molding technician job description tells candidates what the role owns on your plant floor: which presses and materials they work with, whether they perform setups or changeovers, how quality checks are handled, and when they escalate process or equipment issues. The template below is employer-facing and customizable. It is not a universal job standard: define each responsibility around your actual process, training, equipment, and safety procedures.

Injection Molding Process Technician Job Description Template
Job title: [Injection Molding Process Technician / Molding Technician / your plant’s title]
Location: [City, State]
Shift and schedule: [Shift, days, and schedule]
Reports to: [Production Supervisor / Process Engineering Manager / other role]
Work arrangement: [On-site location and relevant work environment]
Position summary
[Company] is hiring an [Injection Molding Process Technician] to support [products, molding cells, and shift]. This role is responsible for [the specific setup, process-monitoring, quality, and documentation duties assigned at this facility]. The technician works with [operators, quality, maintenance, and engineering] to follow approved work instructions, identify process or product issues, and communicate them to the right owner.
Use the brackets to describe your operation. State whether this person runs production, completes setups or mold changes, adjusts approved process settings, supports troubleshooting, or leads technical work. Do not combine all of those duties under “technician” unless the position actually includes them.
Core responsibilities
Select and tailor the responsibilities that belong to this position:
- Follow the approved setup sheets, work instructions, and production priorities for assigned molding machines and cells.
- Monitor and record the process information specified by the plant’s control plan, and raise out-of-range conditions through the defined escalation process.
- Support mold setup, changeovers, startups, and shutdowns when those tasks are part of the role and the employee is trained and authorized to perform them.
- Inspect parts and review documented quality checks at the frequency and acceptance criteria set by the plant; identify, contain, document, and escalate suspected nonconforming product according to site procedures.
- Work with production, quality, maintenance, and engineering to investigate recurring process or product concerns and communicate findings at shift handoff.
- Maintain accurate production, setup, quality, and downtime records in the plant’s required systems.
- Keep the work area and equipment in the condition required by the plant’s housekeeping and safety procedures; stop and escalate work when a safety condition is unclear or unsafe.
Qualifications to specify
Separate true requirements from preferences so qualified applicants can tell whether they should apply.
- Relevant experience: Identify the experience that matters for your operation—such as injection molding production, process monitoring, setups, mold changes, troubleshooting, or a defined combination.
- Equipment and process scope: Name the press types, controls, auxiliary equipment, materials, products, or mold complexity the employee will encounter. Include only equipment and processes used at this facility.
- Quality and documentation: State the inspection methods, measurement tools, quality systems, and recordkeeping the role actually uses.
- Training: List required licenses, certifications, or training only when the position or applicable site procedure requires them. Otherwise, explain what training is provided.
- Physical and schedule requirements: Describe the actual shift, work setting, and essential job requirements accurately, using your organization’s established job-analysis process.
O*NET groups molding, coremaking, and casting machine setters and operators in a broad occupation. Its profile is useful as a general reference for machine-operation and production tasks, but it is not a ready-made specification for every injection molding technician role. Review the O*NET occupation profile and then define the work at your plant.
Clarify where this role starts and ends
Job titles vary across plants. An operator may primarily run a documented process and inspect output; a process technician may own additional setup, process monitoring, or troubleshooting duties; a process engineer may be accountable for broader process design or improvement. Those boundaries are not universal. In your posting, name the decisions the technician can make independently, the changes that require approval, and the issues that should go to engineering or maintenance.
Use a consistent interview scorecard
Ask candidates for specific examples, then score each area against the same job-related criteria:
- Process scope: “Tell us about the machines, materials, products, and shift responsibilities in your most relevant role.”
- Setup and changeover: “Which setup or changeover steps were you trained and authorized to perform? How did you confirm the approved instructions?”
- Quality response: “Describe a time you found a part or process concern. What did you document, contain, and communicate?”
- Troubleshooting and escalation: “Give an example of a recurring process issue. What information did you gather, and when did you involve maintenance, quality, or engineering?”
- Safety and handoff: “How do you confirm the applicable site procedure before work, and what do you do when a condition or instruction is unclear?”
Use a simple, consistent rating scale and document evidence from the answer. Keep interview questions tied to the actual role and evaluate candidates against the same criteria.
Make safety responsibilities specific to the site
Injection molding equipment can expose workers to moving parts, pinch points, hot surfaces, and other hazards. OSHA’s plastics-machinery guidance discusses guarding for horizontal injection molding machines and notes the importance of an effective lockout/tagout program and appropriate protective equipment when required. Review OSHA’s machine-specific guidance and connect the job posting to your plant’s current safety program, equipment instructions, and training. This template is not a substitute for a safety assessment or site procedure.
Before you publish the job opening
- Confirm the title reflects the work and level of authority.
- Specify the machines, products, materials, shift, reporting line, and responsibilities that distinguish this job.
- Separate minimum qualifications from preferred experience and state what training is available.
- Include the location and compensation information your organization is prepared to share.
- Review the posting with the hiring manager, HR, and the people responsible for quality and safety.
