Core Responsibilities

Primary Functions

Perform comprehensive preventative maintenance on complex injection molds, stamping dies, and fixtures according to established schedules and procedures to prevent unexpected failures.
Conduct detailed troubleshooting and root cause analysis of tooling-related defects in production parts, such as flash, shorts, burns, or dimensional inaccuracies.
Execute timely and precise corrective repairs on damaged or worn tooling, which may include welding, grinding, stoning, polishing, and fitting of intricate components.
Set up, operate, and maintain a variety of toolroom equipment, including manual lathes, milling machines, surface grinders, and CNC machines, to fabricate or modify tool components.
Interpret and work from complex engineering drawings, blueprints, 2D/3D CAD models, and technical specifications to ensure all work meets strict dimensional requirements.
Perform final tool assembly and disassembly, ensuring all components are correctly fitted, timed, and functioning according to design specifications.
Conduct thorough in-press servicing and troubleshooting of tooling to resolve production issues directly on the manufacturing floor, minimizing equipment downtime.
Utilize a wide range of precision measurement instruments, such as micrometers, calipers, height gauges, and indicators, to inspect and verify the dimensions of new, repaired, and modified tooling.
á- Document all maintenance, repair, and modification activities meticulously in the maintenance management system (CMMS) to maintain accurate historical records for each tool.
Manage and maintain an organized inventory of spare tooling components, inserts, and hardware, and initiate requisitions for new parts as needed.
Collaborate directly with the production and processing teams to optimize tool performance, reduce cycle times, and improve overall part quality.
Participate in the design review process for new tooling, providing critical feedback on manufacturability, maintainability, and durability.
Polish and finish mold cavities, cores, and other surfaces to required specifications, often dealing with very fine or mirror-like finishes (e.g., SPI A-1).
Safely operate overhead cranes, forklifts, and other material handling equipment to transport and position heavy tooling and components.
Develop and implement robust lockout/tagout (LOTO) procedures when performing maintenance on tools both in and out of the press.
Support engineering change orders (ECOs) by performing necessary modifications to existing tooling accurately and efficiently.
Evaluate the condition of production tooling to recommend major overhauls, refurbishments, or replacement to engineering and management.
Develop and refine standardized work instructions and procedures for common tool maintenance and repair tasks.
Respond urgently to unscheduled machine-down situations, demonstrating a sense of urgency to diagnose and fix tooling problems to get production running again.
Adhere to all company safety policies and promote a culture of safety and 5S/6S organization within the toolroom environment.
Spot and repair water, oil, or hydraulic leaks on molds and dies, including the replacement of O-rings, seals, and fittings.

Secondary Functions

Assist engineering and quality teams with new tool trials, providing hands-on support and feedback during the validation process.
Champion and actively participate in continuous improvement initiatives, such as Kaizen events, to enhance toolroom efficiency and tooling performance.
Mentor and provide technical guidance to apprentices or junior technicians, sharing knowledge of best practices in tool maintenance and repair.
Support the evaluation and implementation of new toolroom technologies, equipment, and repair techniques to improve departmental capabilities.
