PROCEDIMIENTO PARA LA PREPARACION DE UTILES DE SOPORTE PARA HILERA DE EXTRUSION. |
摘要 |
<p>A process for preparation of support tooling for extruding dies is described in which a substantial reduction in machining is experienced by utilizing a pattern destroying precision casting system in which the pattern is adjusted to shrinkage and provided with a die orifice opening staged up in size to suit the particular support role of the tooling as in a backer or bolster. This is significant because such support elements are regarded as one-of-a-kind structures. Finish machining and treatment requires minimal time and at substantial energy reduction. The pattern is prepared from a destructible or vaporizable plastic material replaced by the molten metal conforming to the mold configuration.</p> |
