Tool Design Engineer

General Summary

A Tool Design Engineer is responsible for designing molds for thermoplastic injection and extrusion blow molding processes. This position requires a strong understanding of mold design principles, material properties, and manufacturing techniques to ensure efficient, high‑quality mold production. The designer will collaborate with engineers, production teams, and suppliers to create cost‑effective, durable, and precise molds that meet product specifications and quality standards.

• Design injection and extrusion blow molds for manufacturing plastic parts, ensuring they meet customer specifications and requirements.
• Use CAD software (e.g., Siemens NX, Solid Works) to create detailed mold designs and 3D models.
• Specify appropriate mold materials and determine the necessary mold features (e.g., gate location, cooling systems, venting, and parting lines) to reduce cycle times and improve part quality.
• Design tooling for complex features, such as undercuts, inserts, slides, and ejection systems.
• Ensure that the tooling is robust and that it meets the established criteria and specifications.
• Evaluate and recommend improvements to existing mold designs to increase efficiency, reduce wear, or lower production costs.
• Work closely with product engineers, toolmakers, and production teams to refine designs and ensure compatibility with injection and extrusion blow molding processes.
• Coordinate with suppliers to source materials and components for mold production.
• Troubleshoot mold issues and recommend corrective actions to improve production quality.

• Degree in Mechanical Engineering or Plastics Technology or Engineering related degree preferred.

• 3-5 years of experience in new tool design.
• 5 years of experience in a plastics molding environment preferred.
• Experienced with safe working practices.
• Some background in product design.

• Comprehensive knowledge and experience in the design and construction of plastic injection molds.
• Substantial knowledge and experience in the design and construction of extrusion blow molds.
• Comprehensive knowledge and experience in the development of mold concepts.
• Must have strong time management skills.
• Have strong collaboration, communication and presentation skills, both oral and written.
• Detail‑oriented with a focus on precision and quality.
• Proficient in mold flow analysis and simulations.

• This is largely a sedentary role, requiring use of typical office equipment such as a computer, copy machine, laptop and cell phone. May be required to lift up to 40 pounds occasionally. Most work is completed in a corporate office environment.
