Dualform is a patented process incorporating a special Double Acting Hydraulic Press. This process enables the simultaneous manufacture of matched top and bottom dies within the press, which in turn are used for the manufacture of finished pressed panels. More than 250 Dualform presses have been sold worldwide.
Dualform tools are cast using a unique, low melting point, alloy called ‘Jewelite’, housed in a special bath situated within the press toolspace. After use, the tools are melted down in situ and new tools are cast. The process can be completed in approximately 3 hours on the smaller presses and under 24 hours on the larger Dualform models. The operation can easily be repeated for each new (or repeat) batch of pressed components.
The Dualform Process enables the manufacturer to make significant savings both in production and in tooling costs. From the creation of matched top and bottom dies to the production of finished components, the Dualform process provides the manufacturer with total production flexibility and a dramatically reduced time-to-market for new products and designs.
Minimal tooling costs and quick tool manufacture ensure that Dualform is an extremely cost effective method of prototype engineering and low volume production.
