Core Responsibilities

Primary Functions

  • Prepare, set up and maintain molds and cores to specified patterns and tooling requirements, ensuring proper dimensions, gating and riser systems for quality iron castings.
  • Heat, charge and monitor the furnace (cupola, induction, or electric arc) to achieve and maintain proper molten iron chemistry and temperature for the scheduled pours.
  • Safely handle and transport ladles, crucibles and molten metal using cranes, hoists and tongs; follow approved rigging and crane signals to ensure safe pours.
  • Execute pouring operations with precision, controlling flow rate, pour height and turbulence to minimize inclusions, cold shuts and other casting defects.
  • Inspect patterns, cores and mold assemblies prior to pouring to verify alignment, venting, and core lock; make adjustments and repairs to tooling when necessary.
  • Perform shakeout, break-out and initial fettling of castings, removing sand, risers, gates and burrs while minimizing damage to the casting surface and geometry.
  • Conduct cleaning, grinding, shot blasting and surface finishing operations to meet dimensional tolerances and surface quality standards.
  • Identify and record casting defects (shrinkage, porosity, hot tears, cold shuts, misruns) and perform corrective actions in coordination with metallurgists and quality control.
  • Sample molten metal and finished castings for chemical analysis, hardness testing and microstructure verification; document results and escalate nonconforming conditions.
  • Follow and apply heat-treatment schedules (normalizing, annealing, quenching) where required and coordinate with heat treat team for controlled cooling and distortion control.
  • Read and interpret engineering drawings, dimensional tolerances, and routing sheets to set up operations and verify final part acceptance criteria.
  • Maintain accurate production records including pour logs, melt records, inspection reports and scrap/rework documentation in accordance with company and regulatory requirements.
  • Operate and maintain core ovens, core shooters, sand mixers, rammers and other foundry support equipment to ensure consistent mold and core quality.
  • Perform routine preventive maintenance and minor repairs on casting equipment, furnaces, cranes and tooling; report major issues to maintenance for timely resolution.
  • Implement and adhere to lockout/tagout, confined space and hot work safety protocols to protect personnel and equipment in the melting and pouring areas.
  • Support root cause investigations and corrective action plans for recurring casting issues by collecting data, running controlled trials, and validating process changes.
  • Train and mentor junior casters and temporary staff on safe pouring practices, mold handling, finishing techniques and quality expectations.
  • Manage and optimize sand control parameters (moisture, clay content, grain size) and refractories to reduce scrap and extend tooling life.
  • Coordinate with pattern shop to troubleshoot pattern wear, dimensional drift and to implement design changes that improve castability and reduce rework.
  • Participate in continuous improvement and lean manufacturing initiatives to reduce cycle time, lower scrap rate, and improve yield in the casting process.
  • Ensure compliance with environmental regulations for foundry operations, including proper handling of dust, slag, spent sand, and metallurgical waste streams.
  • Assist in scheduling and production planning to meet delivery dates, balancing furnace capacity, shift loads and secondary operations throughput.
  • Use basic process control and instrumentation (pyrometers, thermocouples, spectrometers) to monitor and adjust casting parameters for consistent metallurgical results.

Secondary Functions

  • Support continuous improvement projects by contributing front-line casting expertise, running pilot process changes, and validating outcomes.
  • Collaborate with quality engineering to implement inspection checkpoints and statistical process control (SPC) for critical dimensions and metallurgical properties.
  • Assist in maintaining supply inventories of refractories, consumables, cores and patterns; communicate shortages and lead times to planning.
  • Participate in cross-functional safety audits, daily pre-shift meetings, and 5S/visual management activities to improve shop-floor organization.
  • Provide input to tooling purchases and pattern redesigns to improve maintainability, reduce cycle times, and lower scrap rates.
  • Support ad-hoc customer or engineering requests for engineering samples, prototype castings, and process capability data.
  • Contribute to training materials and standard operating procedures (SOPs) for casting processes, safety, and maintenance tasks.
  • Help troubleshoot furnace and ancillary equipment malfunctions and suggest practical, low-cost improvements to increase uptime.
  • Maintain accurate documentation of process changes, nonconformances, and corrective actions to support audits and continuous improvement efforts.
  • Mentor newer team members on foundry best practices, safety awareness, and quality expectations to build team capability and resilience.
