Job Summary: Tooling Engineer III is a senior-level role responsible for leading the design, development, and qualification of plastic injection molds and tooling systems. This position plays a critical role in ensuring tooling meets performance, quality, and costobjectivesfor both prototype and production environments. Key Responsibilities: Lead the design and development of injection molds for plastic components using 2D/3D CAD software. Collaborate with internal teams and external vendors to define tooling specifications and ensure mold performance meets standards. Review customer drawings and specifications to assess feasibility and tooling requirements. Conduct tolerance stack-up analysis and apply GD&T principles for molded part inspection and tooling design. Manage tooling projects including budgeting, scheduling, and reporting to project stakeholders. Organize and lead mold design reviews, ensuring documentation is updated and standardized. Plan, coordinate, and execute mold trials tovalidatetooling performance and part quality. Analyze trial results and implement design or process changes tooptimizemold functionality. Work closely with process engineers and technicians during mold sampling and troubleshooting. Document mold trial procedures, outcomes, and corrective actions for continuous improvement. Support tooling trials, validations, and troubleshooting tooptimizemold performance and part quality. Providetechnical guidance to manufacturing teams andassistin resolving tooling-related production issues. Oversee refurbishment and maintenance of existing molds and tooling systems. Maintain detailed documentation including specifications, drawings, and work instructions. Tools Used in Mold Trials: Injection Molding Machine (IMM):Horizontal or vertical machines used to inject molten plastic into molds. Temperature Control Units:Maintainconsistent mold and melt temperatures to prevent defects. Cavity and Core Inserts:Define the shape and internal features of molded parts. Sprue, Runner, and Gate Systems:Direct molten plastic into mold cavities efficiently. Mold Flow Analysis Software:Simulate andoptimizeplastic flow within the mold. Pressure and Temperature Sensors:Monitorreal-time conditions during trials. Robotic Automation Systems:Assistwith part removal and handling during trials. Inspection Tools:Calipers, CMMs, and visual inspection systems for part validation. Trial Documentation Templates:Used to record parameters like injection pressure, speed, cooling time, and part quality. Qualifications: Bachelor's degree in mechanical engineering, Plastics Engineering, or related field. 5+ years of experience in plastic injection mold design and tooling development. Proficiencyin CAD software (e.g., SolidWorks, AutoCAD, NX). Strong understanding of polymer materials, mold-making techniques, and machining processes. Experience with GD&T, tolerance analysis, and ANSI/ISO standards. Knowledge of plastic part design for manufacturability and cosmetic quality. Excellent project management, communication, and problem-solving skills. Preferred Skills: Experience with mold flow analysis and CAE tools. Familiarity with GMP, ISO, and FDA regulatory requirements. Hands-on experience in mold sampling, validation, and troubleshooting. Ability to lead cross-functional teams and mentor junior engineers
