Core Responsibilities

Primary Functions

Analyze and interpret complex engineering drawings, blueprints, sketches, and 3D models to determine the optimal sequence of operations for fabricating tools, dies, or fixtures.
Set up and skillfully operate a wide variety of conventional and CNC machine tools, including lathes, milling machines, surface grinders, and EDM machines, to machine components to extremely tight tolerances.
Perform intricate and precise bench work, including filing, grinding, stoning, and lapping, to ensure the perfect fitting, alignment, and smooth operation of all die components.
Assemble newly fabricated dies, jigs, fixtures, and other tooling, meticulously verifying dimensions, alignments, and clearances using precision measuring instruments like micrometers, calipers, and height gauges.
Conduct comprehensive trial runs of new or repaired dies in stamping presses or injection molding machines to validate performance and ensure produced parts meet strict quality standards.
Troubleshoot and diagnose complex functional issues with in-production tooling in a timely manner to minimize costly downtime, identifying root causes of malfunctions such as wear, misalignment, or breakage.
Execute preventative maintenance schedules and perform systematic repairs on a wide range of stamping dies (progressive, transfer, line), injection molds, and other production tooling to extend their operational lifespan.
Skillfully modify and rework existing tooling based on engineering change notifications (ECNs) or to proactively improve production efficiency, part quality, and overall performance.
Utilize CAD/CAM software (such as SolidWorks, AutoCAD, or Mastercam) to review tool designs, generate machine tool paths, or make minor modifications to component geometry.
Collaborate closely with cross-functional teams, including Engineering, Quality Assurance, and Production, to resolve complex tooling-related issues and contribute to continuous improvement initiatives.
Meticulously document all repair, maintenance, and modification activities in maintenance logs or a Computerized Maintenance Management System (CMMS) for traceability and future reference.
Inspect finished dies and molds for surface smoothness, contour conformity, and functional defects, ensuring they are polished and fully prepared for the production environment.
Select the most appropriate metals, alloys, and other materials for tooling components based on design specifications, stress requirements, and material properties.
Perform or oversee heat treating, hardening, and tempering processes on tool steel components to achieve the desired levels of durability and wear resistance.
Operate overhead cranes, forklifts, and other material handling equipment with a focus on safety to transport and position heavy dies and tooling components within the facility.
Champion a clean, organized, and safe work environment in the tool room, consistently adhering to all company safety policies and 5S principles.
Design, develop, and fabricate custom gauges, templates, and holding fixtures to support both in-process manufacturing and final quality inspection procedures.
Provide technical guidance, mentorship, and on-the-job training to apprentices and less experienced technicians, sharing knowledge of best practices and advanced techniques.
Actively participate in design review meetings for new tooling, providing critical, experience-based feedback on manufacturability, maintainability, and long-term durability.
Estimate the time, materials, and resources required for various tool fabrication or complex repair jobs to assist in project planning, scheduling, and costing.
Verify the conformance of machined or purchased components to specifications using advanced metrology equipment such as Coordinate Measuring Machines (CMMs) or optical comparators.
Manage the inventory of spare parts, tooling components, and raw materials, initiating purchase requisitions as needed to maintain optimal stock levels and prevent production delays.

Secondary Functions

Support production and engineering teams with ad-hoc tooling adjustments and on-the-floor troubleshooting.
Contribute to the organization's continuous improvement, lean manufacturing, and waste reduction initiatives.
Collaborate with quality assurance to translate part defect analysis into effective tooling correction requirements.
Participate in daily production meetings, shift handovers, and safety reviews within the manufacturing department.
