Prodution Supervisor – Injection Molding (Plastics Manufacturing)

If you’ve spent time on a production floor and know injection molding isn’t something you manage from a desk, this role is built for you.

This is a hands-on leadership position at a smaller plastics facility producing 5-gallon buckets. You’ll have real ownership over operations, driving production, solving problems in real time, and leading a tight-knit team where your impact is visible every day.

What You’ll Be Doing

You won’t just be overseeing production; you’ll be in it.

• Lead a team of 6 across production, maintenance, quality, and shipping
• Run daily injection molding operations, including scheduling and staffing
• Monitor and improve machine uptime, cycle efficiency, and throughput
• Manage scrap reduction, downtime tracking, and labor efficiency
• Oversee machine setup, mold/tooling changes, and process adjustments
• Coordinate preventative maintenance to keep equipment running reliably
• Ensure product meets quality specs, tolerances, and customer requirements
• Maintain control of raw materials, WIP, and finished goods inventory
• Troubleshoot processing issues, mechanical problems, and production bottlenecks
• Track and report KPIs (production output, scrap rates, downtime, OEE)
• Drive continuous improvement initiatives on the floor
• Enforce safety standards and 5S practices in a manufacturing environment

Technical Skills That Matter

This role is ideal for someone who understands how plastic parts are made, not just managed.

• Injection molding processes (setup, cycle optimization, troubleshooting)
• Experience with thermoplastics and molding parameters (temperature, pressure, cooling, cycle time)
• Familiarity with molds, tooling changes, and machine setup
• Understanding of preventative maintenance systems and equipment reliability
• Ability to analyze scrap, downtime, and production data
• Exposure to quality control processes and product specifications
• Working knowledge of production scheduling and workflow coordination
• Comfortable using spreadsheets, production reports, and basic systems

What They’re Looking For

• 3–5 years of experience in manufacturing or production leadership
• Background in injection molding or plastics manufacturing is strongly preferred
• Someone who leads from the floor, not from behind a desk
• Strong problem-solving and decision-making skills
• Ability to manage shifting priorities in a fast-paced production environment
• No degree required—hands-on experience matters more

Work Environment

• Active role on the production floor, expect to be on your feet and engaged
• Manufacturing setting with heat, noise, and moving equipment
• Occasional lifting of materials or finished goods
