FORMING METHOD AND APPARATUS HAVING A HYDROSTATIC PRESSING MEDIUM |
摘要 |
<p>A method and apparatus for forming a workpiece having a desired configuration as well as an associated preform assembly are provided. The forming method and apparatus as well as the preform assembly include a hydrostatic pressing medium, such as a layer of glass, disposed within the die cavity proximate to at least one side of the workpiece. The hydrostatic pressing medium is configured to have a relatively low viscosity at the temperatures at which the workpiece is processed, thereby facilitating the relatively even application of pressure to the workpiece. As such, a workpiece having a complex configuration may be formed utilizing a single acting die.</p> |
