Emerging
Entry / Apprentice
  1. Basic precision measuring instruments — identify and use under direct supervision to check surface dimensions of cast or molded parts against specification sheets.
  2. Automatic molding machine operation — observe under close guidance to detect obvious jams or product defects on a production floor.
  3. Metal or plastic casting machine startup procedures — follow step-by-step written instructions with a supervisor present during initial on-the-job training.
  4. Machine valves and dials — adjust pressure, temperature, and feed rate settings as directed by a lead operator on a single assigned machine.
  5. Work orders and basic blueprints — read and interpret with guidance to identify required temperatures, cycle times, and material sequences for a production run.
  6. Meters and gauges — monitor and record temperature and pressure readings at scheduled intervals using a provided log sheet.
  7. Water cooling hoses — connect to die cooling ports using hand tools under direct supervision following a standard safety checklist.
  8. Dies and mold components — remove from machines at the end of a production run following lock-out/tag-out procedures with trainer oversight.
  9. Defective parts — recognize and segregate from conforming product using visual inspection criteria provided on a quality reference card.
  10. Workplace safety rules and machine guarding requirements — follow consistently during all assigned tasks in a molding or casting production cell.
Developing
Mid-level / Established
  1. Precision calipers, micrometers, and gauges — apply routinely and independently to verify dimensional conformance of molded or cast metal and plastic parts.
  2. Continuous automatic machine operation — monitor across a full shift, identifying early signs of malfunction or drift and making minor adjustments without supervisor direction.
  3. Metal and thermoplastic molding or coremaking machines — set up and operate for standard production runs, following process sheets with minimal oversight.
  4. Temperature, pressure, and cycle-time parameters — regulate by turning valves and dials to maintain consistent output quality during routine production.
  5. Blueprints and production work orders — read independently to plan setup sequences, select tooling, and verify material requirements before a run begins.
  6. Gauge and meter readings — record accurately in shift logs or spreadsheet software, flagging out-of-range values and notifying a lead operator promptly.
  7. Die cooling system connections — complete efficiently using hand tools, confirming flow and leak-free seals before authorizing machine start.
  8. Post-run die removal — perform safely and efficiently, inspecting removed tooling for wear and reporting findings to maintenance or tooling staff.
  9. In-process quality checks — conduct at defined intervals using inspection criteria, distinguishing acceptable variation from non-conforming conditions.
  10. Production pace and task sequencing — manage within a shift to meet daily output targets while maintaining machine uptime and product quality standards.
Proficient
Senior / Expert IC
  1. Complex or multi-cavity molds and dies — set up and fine-tune autonomously across a range of metal and plastic materials, resolving non-standard process conditions independently.
  2. Automatic and semi-automatic casting or molding lines — monitor across multiple machines simultaneously, diagnosing root causes of recurring jams or quality drift and implementing corrective actions.
  3. Process parameter optimization — adjust temperature, pressure, speed, and cycle-time profiles to improve yield and reduce scrap on challenging or new production jobs.
  4. Full blueprint and engineering specification packages — interpret without assistance to plan complete production sequences, tooling requirements, and quality control checkpoints.
  5. Statistical process control data — analyze using analytical or industrial control software to identify trends and prevent defects before they reach downstream operations.
  6. Industrial control software and CAM software — configure machine programs and verify tool paths to support setup of new or modified molds and casting tools.
  7. Tooling wear and dimensional drift — diagnose from inspection data and coordinate corrective tooling adjustments with maintenance or tool-room staff to restore conformance.
  8. Non-routine or off-spec material conditions — evaluate, determine appropriate process modifications, and document decisions in ERP or production tracking systems.
  9. Cross-shift quality and production records — review and synthesize to identify systemic issues and recommend process or procedural improvements to supervisors.
  10. Junior operators and new hires — guide through machine setups, quality inspections, and safety protocols, sharing technical knowledge gained from hands-on production experience.
Advanced
Lead / Principal / Executive
  1. Molding, coremaking, and casting process standards — establish and maintain across an entire production department, ensuring alignment with engineering specifications and customer quality requirements.
  2. Shift-level production planning and scheduling — direct using ERP software to balance machine capacity, material availability, and labor resources for maximum throughput.
  3. Departmental quality control systems — design and implement, including inspection sampling plans, acceptance criteria, and corrective action workflows for metal and plastic casting operations.
  4. Capital equipment selection and tooling investments — evaluate and recommend by applying deep knowledge of casting and molding processes, machine capabilities, and production economics.
  5. Process improvement initiatives — lead using data from industrial control and analytical software to drive measurable reductions in scrap, cycle time, and downtime across the operation.
  6. Technical training curriculum for machine operators — develop and deliver, covering safe machine operation, blueprint reading, precision measurement, and quality inspection for Job Zone 2 production staff.
  7. Cross-functional collaboration with engineering, maintenance, and quality teams — facilitate to resolve complex tooling, material, or process failures that exceed the scope of floor-level troubleshooting.
  8. Workplace safety programs for molding and casting environments — champion by setting behavioral standards, conducting audits, and driving compliance with lock-out/tag-out and hazardous material protocols.
  9. Operator performance and skill development — assess systematically and create individualized development plans that advance staff from emerging to proficient competency levels.
  10. Production metrics and key performance indicators — report to plant leadership using spreadsheet and ERP data, translating floor-level operational data into strategic recommendations for continuous improvement.
