Core Responsibilities

Primary Functions

Prepare and inspect reusable and expendable molds and cores by setting patterns, packing sand, applying binders, and assembling cores to ensure dimensional stability and proper venting prior to pouring.
Measure, charge, and operate melting furnaces (induction, cupola, or crucible) to achieve specified alloy chemistry and temperature targets, following metallurgy controls and heat charts.
Skim, flux, and degas molten metal as required, monitoring temperature and composition with pyrometers and spectrometers to meet casting specifications and metallurgical requirements.
Execute manual pouring of molten metal into molds and cores using ladles or automatic pouring aids, controlling pour speed, turbulence, and gating engagement to minimize defects such as porosity and cold shuts.
Monitor and control gating systems and riser placement during pour operations; adjust techniques on-the-fly to compensate for mold variability and achieve sound castings.
Remove cooling castings from molds, perform gutting, shakeout, and primary cleaning operations safely using hand tools and power equipment to separate casting from molding materials.
Perform hand fettling, grinding, shot blasting, trimming, and surface finishing to remove gates, risers, flash, and parting lines while maintaining dimensional tolerance and surface finish standards.
Conduct visual and dimensional inspections of castings against blueprints and engineering drawings, using calipers, micrometers, gauges, and templates to verify critical features.
Identify and document casting defects (e.g., shrinkage, cold laps, inclusions) and root-cause issues; recommend corrective actions for mold preparation, gating, or process parameters.
Maintain strict compliance with foundry safety practices, including use of PPE, hot work permits, and handling of hazardous materials; participate in toolbox talks and safety audits.
Maintain production records, batch logs, metal charge records, and heat identification tags to support traceability and metallurgical compliance.
Collaborate with patternmakers and engineers to suggest design or gating modifications to improve castability, reduce scrap, and increase yield on complex geometries.
Train and mentor junior casters and foundry assistants on safe pour practices, mold preparation techniques, and finishing operations to build team capability.
Operate and maintain hand tools, grinders, band saws, presses, and power finishing equipment; perform routine preventive maintenance and report equipment issues to maintenance personnel.
Coordinate with heat treat and NDT teams to ensure proper post-cast processing schedules and inspection plans, including radiography, ultrasonic testing, and hardness checks.
Implement process improvements to optimize cycle times, reduce material waste, and improve first-pass yield using foundry best practices and lean manufacturing principles.
Follow and execute specific casting procedures for specialty processes such as investment casting, shell molds, or centrifugal casting as required by product or customer specification.
Ensure proper storage, handling and disposal of foundry materials such as refractory mixes, binders, reclaim sand, and chemical additives in accordance with MSDS and environmental regulations.
Read and interpret engineering drawings, prints, and CAD-derived templates to set up molds and fixtures for complex cast parts, ensuring orientation and dimensional criticalities are met.
Maintain a clean, organized work area and contribute to 5S and continuous improvement activities to improve foundry workflow and reduce safety hazards.

Secondary Functions

Assist with sample preparation and metallographic sectioning for quality investigations and lab testing when requested.
Support inventory control by reporting sand, alloy, and consumable levels and assisting in material requisitions to prevent production interruptions.
Participate in cross-functional troubleshooting with engineering and maintenance to diagnose recurring defects, mechanical failures, or equipment misalignments.
Provide input to standard operating procedures (SOPs) and work instructions based on hands-on experience and process observations.
Participate in continuous improvement projects to reduce scrap, energy consumption, and cycle time while maintaining casting integrity.
Assist in training programs and skills assessments for new hires and temporary staff assigned to casting operations.
Support root cause investigations by providing production insights and contributing to corrective action documentation.
Perform basic environmental monitoring and housekeeping tasks to ensure compliance with plant housekeeping and environmental guidelines.
Communicate with production planning to prioritize orders and adjust work sequencing to meet customer delivery dates.
Participate in weekly safety and quality meetings, contributing feedback and suggestions to improve overall foundry performance.
