Polymeric tooling boards are currently used by the aerospace and automotive industries primarily for master-mold manufacturing. Generally, they don’t possess the required thermal stability, conductivity and thermal expansion values required to laminate high-temp prepregs. The industry standards are currently aluminum and other metallic alloys, despite their weight, cost and lengthy machining time. Our objective was to develop a highly-conductive polyurethane board, with low CTE, and offer a process improvement to current aerospace and automotive tooling methods.
- Be aware of alternatives to metals and epoxy boards for moulds/master models manufacturing
- Appreciate the benefits of using a conductive board for high temperature moulds
- Evaluate a cost-effective alternative to aluminum and metal alloys for the manufacturing of moulds devoted to prototypes and small series
