Mold Tool Maker

About the Role

We are seeking a skilled Mold Tool Maker to maintain, repair, and modify our inventory of over 100 active plastic injection molds. In this role, you will focus on mold repair, preventative maintenance, engineering change modifications, and spotting in new molds or details—not building new molds from scratch.

Responsibilities

• Diagnose and repair damaged, worn, or malfunctioning injection molds to minimize production downtime.
• Modify existing mold components and details to reflect engineering design updates.
• Spot in and fit new molds, core/cavity inserts, and replacement details to ensure precise shut-offs.
• Set up and operate manual toolroom machinery including mills, lathes, and grinders (no CNC operation required).
• Perform high-precision TIG and micro-laser welding to repair parting lines, gates, and worn tool details.
• Execute precise hand polishing, fitting, deburring, and bench assembly of complex mold components.
• Perform routine mold teardowns, cleanings, inspections, and lubrication per production schedules.

Requirements

• Minimum 3–5 years of dedicated experience in plastic injection mold repair or toolmaking.
• Proven proficiency in both TIG welding and precision laser welding for tool steels.
• Strong competency operating manual toolroom equipment (mills, lathes, surface grinders).
• Ability to read and accurately interpret 2D engineering drawings, blueprints, and tool schematics.
• Expert use of precision measuring instruments including micrometers, calipers, indicators, and height gauges.
• Strong mechanical troubleshooting skills to identify tool wear, flashing issues, and parting line defects.

Physical Requirements

• Ability to safely lift and maneuver heavy mold components up to 50 lbs.
• Excellent hand-eye coordination and manual dexterity for prolonged, intricate bench work.

Position Type: Regular, on-site at our Spartanburg, SC manufacturing plant.
