Responsibilities

• Build, construct, and CNC machine master patterns, plugs, and molds from scratch using hardwood, plywood, Ren Shape/polyurethane tooling boards, and epoxy.
• Set up and operate 3-axis and 5-axis CNC routers and mills to precisely machine, trim, and finish 3D-printed polymer patterns into production-ready thermoforming plugs.
• Modify, repair, and rework existing cast aluminum molds when engineering changes or production wear require updates; perform precise drilling, milling, and manual bench work on aluminum tooling.
• Sand, fill, polish, and apply heat-resistant coatings to machined 3D prints, wood, Ren board, and aluminum surfaces to achieve optimal, defect-free finishes.
• Inspect all tooling to guarantee proper draft angles for clean part release, and drill or clear precise vacuum vent holes to optimize production airflow.
• Load, test, and optimize CNC programs; perform basic G-code edits at the controller to accommodate variations in wood, printed polymers, and cast aluminum.
• Use calipers, micrometers, and depth gauges to inspect finished tools, ensuring they maintain tight engineering tolerances (± 0.005").
