Our team designs and manufactures precision-molded seals, gaskets, and custom rubber components that perform in the most demanding environments. We take pride in craftsmanship, collaboration, and a culture built on innovation and reliability.

Key Responsibilities

Optimize mold designs for manufacturability, cycle time reduction, part quality, venting, gating, and automation compatibility. Collaborate with product engineering, manufacturing, quality, and process engineering teams to ensure tooling meets functional and production requirements. Develop and maintain tooling documentation, revision control, BOMs, maintenance standards, and engineering change records.

Generate mold design concepts (Solidworks) to support new products, or re-design tooling for existing products to improve efficiency. Lead tooling troubleshooting activities related to flash, short shots, air entrapment, knit lines, dimensional variation, and cosmetic defects. Coordinate with external tool shops, suppliers, and internal machining teams during tool fabrication and qualification.

Recommend improvements for tooling reliability, preventive maintenance, and process capability. Support continuous improvement initiatives related to tooling performance, scrap reduction, and manufacturing efficiency. Create detailed 3D CAD models, mold layouts, and manufacturing drawings. Support mold flow analysis, tolerance stack-ups, shrinkage calculations, and DFM reviews.

Participate in mold trials, process validations, FAI activities, and production launches. Ensure compliance with customer specifications, ISO standards, safety requirements, and industry regulations. Ability to travel to Tooling vendors as needed, travel time up to 10% Required Qualifications Bachelor’s degree in Mechanical Engineering, Manufacturing Engineering, Tool Engineering, or related field.

8+ years of experience in injection mold design, preferably with Liquid Silicone Rubber (LSR) or elastomeric materials. Proficiency with CAD software such as Solid. Works, or AutoCAD. Strong understanding of injection molding principles, mold construction, hot runner systems, venting, cooling, and automation. Experience interpreting GD&T and engineering drawings.

Knowledge of mold manufacturing processes including CNC machining, EDM, polishing, and tool assembly. Strong analytical and problem-solving skills. Excellent communication and project coordination abilities.

Preferred Qualifications

Proficient at mold design using Solid-Works (3D Design, tooling for molding). Experience with medical-grade or high-precision LSR components. Experience with multi-cavity, cold deck, or valve gate LSR tooling systems. Understanding of validation protocols (IQ/OQ/PQ). Knowledge of cleanroom manufacturing environments. Lean manufacturing or Six Sigma experience.
