| titleOfInvention |
Extrusion dies having different shaped input and output orifices and an intermediate region of uniform variation in cross-section per unit of distance |
| abstract |
An extrusion die is made by stretching a flexible membrane having one end held in a shape conforming to the input end of the die and the other end maintained in conformity with the desired profile of the part to be extruded. A fluid having hardening properties is applied to one surface of the distended membrane. Once the material has hardened, the flexible diaphragm is stripped away, and the resultant contour is coated with a material to form the contour of the die. This contour is cast in a shell, with appropriate heat and heat sensing elements, to form the die. |
