Teaches the design and operation of the T-type, the Coathanger, and the Curved Manifold sheet die designs, as well as how the restrictor bar and the die gap adjustment are used to control plastic flow through the sheet die.
Plastics EXTRUDER for supplying a steady source of plastic melt to the die through BREAKER PLATE. Understanding of screw plasticising ∓ temperature profile is important. Optimised screw design to handle specified polymer is required. Understanding function of BREAKER PLATE. a means of COOLING and SIZING SYSTEM.
Plastic Flow, LLC, Hancock, Mich., has just released a new version of its polyXtrue extrusion die design software. The new version can run inside Autodesk Inventor as an add-in, as well as many other new advanced analysis capabilities.
