Core Responsibilities

Primary Functions

Strategically build and prepare 'trees' by attaching multiple wax patterns to a central sprue, meticulously optimizing for metal flow, gas release, and ensuring complete, uniform fills for each piece.
Operate and maintain advanced casting equipment, including programmable burnout kilns, vacuum casting machines, and centrifugal casters, ensuring all machinery is calibrated for optimal performance and safety.
Meticulously prepare and invest wax trees, precisely mixing investment powder to the correct consistency and utilizing vacuum techniques to eliminate all air bubbles, creating flawless, high-resolution molds.
Calculate, weigh, and melt specific quantities of precious metals and alloys, such as gold, platinum, silver, and palladium, adhering to strict temperature controls and protocols to achieve desired karats and colors.
Execute multi-stage burnout cycles for investment molds based on pre-defined schedules, guaranteeing the complete elimination of wax and the proper curing of the mold for superior casting quality.
Perform the critical casting process, expertly pouring molten metal into heated molds using either vacuum-assist or centrifugal force to achieve dense, porosity-free results for intricate designs.
Manage the devesting and quenching process, carefully breaking away the investment material to reveal the cast metal tree without shocking or damaging the freshly cast, delicate jewelry pieces.
Expertly clip castings from the tree and meticulously grind down sprues using various hand tools and machinery, preparing the raw jewelry for subsequent finishing, pre-polishing, and stone-setting stages.
Conduct rigorous, post-cast quality control inspections on all raw castings, using magnification to identify and diagnose defects such as porosity, shrinkage, flashing, or incomplete fills.
Create, maintain, and categorize high-quality rubber or silicone molds from master models using a vulcanizer or room-temperature vulcanizing (RTV) compounds, ensuring longevity and detail retention.
Operate modern wax injection machines to produce thousands of consistent, high-detail wax patterns, skillfully adjusting temperature, flow, and pressure settings to accommodate various mold complexities.
Maintain a detailed, comprehensive log of all casting operations, diligently recording metal types, weights, casting parameters, flask temperatures, and quality control outcomes for traceability and process analysis.
Manage the inventory of casting grain, master alloys, and other essential supplies like investment powder and crucible liners, forecasting needs and coordinating with procurement to prevent production stoppages.
Skillfully refine and reclaim precious metal from sprues, gates, filings, and defective castings through established processes to minimize waste, reduce costs, and maximize material yield.
Collaborate closely with CAD designers and model makers to provide critical feedback on design castability, suggesting modifications to geometry, thickness, or details to improve casting success rates.
Act as the primary troubleshooter for casting issues, systematically analyzing defects to determine root causes and adjusting process variables like treeing strategy, burnout cycles, or casting temperatures to resolve them.
Champion and adhere to all environmental health and safety regulations, including the proper use of personal protective equipment (PPE) when handling molten metals, chemicals, and high-temperature equipment.
Perform routine preventative maintenance, cleaning, and calibration on all casting, mold-making, and processing equipment to ensure consistent operation, safety, and department longevity.
Develop, refine, and document standard operating procedures (SOPs) for all casting-related processes to ensure consistency across the team and to facilitate effective training for new personnel.
Stay current with emerging casting technologies, innovative materials, and advanced techniques by reading trade publications and attending workshops, recommending and implementing process improvements to enhance quality and efficiency.
Liaise effectively with the finishing, polishing, and stone-setting departments to ensure a smooth hand-off of cast pieces and to understand how casting quality impacts downstream production requirements.

Secondary Functions

Maintain exceptional cleanliness and organization within the casting department to ensure safety and efficiency.
Assist in training and mentoring apprentices or junior casting technicians on best practices and safety protocols.
Contribute to the organization's data strategy and roadmap by providing accurate production data.
Collaborate with business units to translate data needs into engineering requirements.
Participate in sprint planning and agile ceremonies within the data engineering team.
