Low cost tooling technique for producing pultrusion dies

摘要

A pultrusion die is usually fashioned of multiple pieces. One or more die components, and possibly all die components, can be formed by facing less precisely machined and finished tooling materials with highly polished sheet metal. Other possible die components can be formed from conventionally machined and polished steel surfaces. The surfaces that will form the inside of the die are highly polished. The components are fastened together in a pattern that will assure uniform pressure and good heat transfer among the components. The entrance and exit orifices are optionally provided with beveled edges to improve entrance of materials into and release of the finished product from the die.
