$30/hr. to $33 hr. based on experience

Edge Plastics, Inc. is a polypropylene injection molding manufacturer headquartered in Mansfield, Ohio. We mold and ship storage totes and related housewares for some of the largest retailers in North America, running 37 injection molding machines from 260 to 1,500 tons around the clock. Our tooling is the heart of the business - when a mold runs clean, we ship on time.

That is why this role matters.

We are a hands-on, no-bureaucracy shop. Decisions get made on the floor, good ideas get implemented quickly, and the people who keep our tooling running are recognized for it.

The Tool Specialist is responsible for the condition, performance, and service life of Edge Plastics’ injection molds. This is a working tool room position: you will perform scheduled preventive maintenance, diagnose and repair molds both in the press and on the bench, and support production with fast, correct fixes when a tool goes down. You will work directly with process technicians, mold setters, and the plant leadership to sustain rated cycle times and part quality.

• Scheduled PM: Perform preventive maintenance on molds per the PM schedule and cycle-count intervals - disassemble, clean, inspect, and reassemble tools to established standards.
• Clean and degrease cavities, cores, slides, and ejector systems; remove gas residue, mold release build-up, and plate-out from polypropylene.
• Inspect and clear vents, gates, runners, and sub-gates to maintain fill and pack.
• Lubricate and service leader pins, bushings, slides, wear plates, cam actions, and ejector components.
• Flush, descale, and pressure-test cooling lines and manifolds; locate and correct restrictions and water leaks.
• Inspect hot runner systems - nozzle tips, heater bands, thermocouples, valve gates - and check circuits for continuity and proper control.
• Apply rust preventative and stage tools properly for storage - maintain mold storage racks and the tool crib.

• Diagnose tooling issues: Determine whether a defect is tool related or process related and communicate findings clearly to the process and production teams.
• Repair and replace ejector pins, sleeves, core pins, lifters, slides, springs, dowels, wear components, and inserts.
• Repair parting line damage, mismatch, flash conditions, and pinched or hobbed steel.
• Weld, machine, stone, polish, and blend mold steel to restore surface, texture, and dimension.
• Machine replacement components using manual mill, lathe, surface grinder, and bench equipment; perform basic fitting and spotting.
• Perform in-press repairs safely and efficiently to minimize downtime and make the call when a tool must come out.
• Support hydraulic, pneumatic, and electrical connections on tooling - core pulls, unscrewing units, hot runner controllers, and safety interlocks.

• Support mold changes and start-ups; verify tool condition, water, and safety straps before a tool goes into the press.
• Assist with first-article and dimensional checks after repair to confirm the tool is producing acceptable parts.
• Participate in new tool
