Tacoma, Washington – General Plastics Manufacturing Company has introduced the Last-A-Foam FR-4800 high-temperature tooling board. The thermally stable board is designed for applications with challenging performance requirements in the aerospace, automotive and composite manufacturing industries.
General Plastics foam tooling board replaces metal
The company claims it fills a gap for companies producing high-tolerance parts who need a tooling system that is cost-effective, and dimensionally predictable and stable.
Last-A-Foam FR-4800 can be used up to peak temperatures of 249°C, and continuous use temperatures up to 204°C. It can be used as an alternative to metallic tooling as its coefficient of thermal expansion is similar to that of aluminium.
The product enables the manufacture of tools and parts for prototypes, concept proofs and short-run production parts, the company said.
‘It can be easily and quickly machined to very complex shapes, and deliver the needed foam master in less time and less overall cost than other tooling methods,’ said Mitchell Johnson, CEO and president at General Plastics.
