Tool Design Engineer

Flambeau Inc.
United States, Wisconsin, Baraboo
Mar 05, 2026

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.

Essential Duties:

* Design injection and extrusion blow molds for manufacturing plastic parts, ensuring they meet customer specifications and requirements.

* Use CAD software (e.g., Siemens NX ,SolidWorks) 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.
