- Develop, implement, and maintain standard operating procedures (SOPs) for each stage of the casting process — from pattern design and molding to pouring, cooling, fettling, and finishing
- Ensure adherence to foundry quality control standards, including control of raw materials, mold preparation, furnace parameters, pouring temperatures, and cooling rates.
- Controlling the chemistry of all cast grinding/ castings, using daily spectrometer results to adjust alloy additions and chromium recovery so each batch of molten steel is correct before it is poured.
- Oversee heat treatment: parameters, hardening, oil quenching and tempering, the controlled heating and cooling that gives each product its final hardness.
- Manage product testing, including hardness checks drop testing, which proves the product will survive repeated impact in a mill without cracking or breaking.
- Analyse daily laboratory and production data to spot deviations early, find root causes and agree corrective actions with the melt shop, casting and heat treatment teams.
- Produce weekly process control reports by product and monthly reports for senior management, covering defects, rework, scrap and test pass rates.
- Supervise and appraise quality inspectors against measurable targets (KPIs) and plan their development through training and job rotation so that they understand the whole process.
- Drive continuous improvement, ISO 9001 practice and safety standards, including projects to improve the quality of the products.

Projects
Reduced the defect rate on high chrome mill balls, across all sizes, from an average of 9% to 3.5%, cutting rejected and reworked balls by more than half., Designed and implemented an emergency tapping switch on the furnace platforms, placed away from the furnace, so operators can pour off molten metal in an emergency without standing next to the furnace, protecting both people and equipment., Developing a storage solution for Heavy Fuel Oil, a thick fuel that solidifies as it cools, so it stays usable and less is wasted.
