Extrusion/Die Practical 100 PR Extrusion Die Specification – How to Obtain Repeatable Performance R.F. Dickson and A. Kindlihagen -- Hydro Aluminum Technology Center, USA Computer software can automatically design dies that balance port flow, offering high productivities and stable geometries. Changes in bearing angle/length affect extrusion speed and shape produced by a die. No accepted industry standard exists for specifying bearing angle and bearing length tolerances when purchasing dies. Specification for die manufacturing standards and simple verification methods for die-makers to meet these standards are proposed. |
