Up to $25.00/hr • Waukesha County / Greater Milwaukee Area • 4-Day Work Week (Fri/Sat/Sun Off) • Air-Conditioned Shop • Direct-Hire

The Opportunity: Secure a permanent, stable professional home with a premier, family-owned plastics OEM known for incredible employee longevity (with multiple team members boasting 10 to 20+ years of tenure). Open strictly due to a well-earned retirement, this dedicated bench-work role operates within a highly modernized, meticulously clean, and fully air-conditioned toolroom. The organization treats its technical staff with immense professional respect, offering a rock-solid schedule featuring a three-day weekend, every single week—no rotations, no exceptions.

• EXPERIENCE DEPTH: 1+ years of dedicated, hands-on injection mold maintenance, troubleshooting, and bench repair experience required
• TECHNICAL FOCUS: Highly precise bench work and tool maintenance—this is a dedicated repair room track (you will not be setting molds into production presses)
• EQUIPMENT & TOOLING: Deep structural familiarity with multi-cavity tooling, hot runner systems, valve gates, electrical zones, and hydraulic core-pull cylinders
• EARNING POTENTIAL: Up to $25.00 per hour starting base (fully scaling with custom mold-build or toolmaking experience) + comprehensive corporate benefits package
• WORK SCHEDULE: Monday through Thursday, 6:00 AM – 4:30 PM | Enjoy a guaranteed 3-day weekend (Friday, Saturday, and Sunday off)
• LOCATION: Waukesha County / Greater Milwaukee corridor (100% onsite role; must reside within a dependable 45-minute daily driving radius)
• COMPLIANCE: United States Citizens or Green Card holders only; corporate visa sponsorship or relocation assistance is not available

If you are a mold technician or toolroom specialist who is tired of the high-stress chaos of high-volume contract molders, unpredictable weekend mandatory overtime, and sweltering summer shop floors, this direct-hire position is a significant quality-of-life upgrade. Because our client is an established OEM that designs and manufactures its own proprietary product lines, the daily pace is controlled, highly organized, and focused entirely on quality craftsmanship over frantic part counts.

You will have total technical ownership over your bench, executing detailed tool tear-downs, component polishing, and preventative maintenance cycles that maximize tool life. This is a rare chance to step into a high-functioning position vacated by a retiring veteran, backed by an elite team of long-tenured professionals who actively collaborate and support one another.

• Precision Bench Tooling: Leading the technical maintenance, failure diagnosis, and close-tolerance repair of high-precision plastic injection molds.
• Tear-Down & Inspection: Disassembling complex tooling, cleaning plates, polishing parting lines, and inspecting cores, cavities, ejector pins, and bushings for wear or damage.
• Hot Runner Troubleshooting: Diagnosing, wiring, and repairing multi-zone hot runner systems, valve gate sequences, electrical thermocouple connections, and hydraulic manifolds.
• Manual Machining: Utilizing manual toolroom equipment—including surface grinders, vertical mills, lathes, and drill presses—to machine or modify secondary inserts, pins, and fixtures.
• Quality & Bench Testing: Conducting rigorous bench testing for water jacket blocks, scale accumulation, leaks, and electrical continuity before releasing tools back to the production floor.
• Documentation & PM Tracking: Maintaining clean digital and physical records of tooling modifications, preventative maintenance schedules, and localized spare parts inventories.
• Safe Rigging: Operating overhead bridge cranes and forklifts to safely transport, split, and manipulate heavy mold frames and bolster blocks.

• Mold Room Pedigree: A minimum of 1 year of verifiable experience troubleshooting and repairing injection molds within a plastic manufacturing environment.
• Toolroom Independence: Proven capability to safely and independently operate standard manual toolroom machinery to fabricate or fit components.
• Diagnostic Skills: A strong analytical mindset capable of tracing electrical shorts in hot runner cables or identifying the root cause of flashing and parting-line defects.
• Employment Stability: A reliable, progressive professional history showcasing strong attendance and multi-year tenures; frequent job-hopping is a disqualifier.
• Technical Pluses: Prior hands-on experience with micro-laser welding, a formal tool and die apprenticeship, or a Toolmaker certification is highly advantageous.
