• Performance checks: cooling lines, vents, and parting lines.
• Rapid response: emergency fixes that get production moving again.
• Process support: trials, startups, and parameter changes with Process Techs and Operators.
• Continuous improvement: identify recurring tooling issues and recommend pragmatic fixes.
• Documentation: keep PMs and repair records crisp and complete.
• Precision work: welding, machining, grinding, polishing, and fine handwork.
• Recreation by measurement: reverse engineer damaged components with CAD and manual metrology.
