摘要:
The present invention discloses a method for designing a profile extrusion die for shaping a polymer resin material into a profile having a plurality of sections. In the present invention, a plurality of operating conditions for shaping the resin material into the profile are determined. The dimensions of each of the plurality of sections of the profile are then specified. The profile dimensions include width and thickness. Extrusion information for the polymer resin including die swell/drawdown and flow balance is obtained. Die dimensions for shaping the profile in accordance with the operating conditions, the profile dimensions, and the extrusion information are then determined.
