Hybrid extrusion tooling.
The 800 Series Hybrid extrusion tooling has been introduced. In some extrusion applications that utilize crossheads and inlines, layers of the exact same material are applied multiple times, using a single die. This method is used to reduce the propensity for errors caused by gels breaking through a thin wall, weld lines, inconsistent wall thickness, plus material and process variations. Additional errors are said to include difficult-to-process materials and demanding applications where there is zero fault tolerance. The inherent benefits of the 800 Series are said to be retained in the 800 Series Hybrid, including compact design, low residence time and a common deflector bore that eliminates tolerance stack up. The challenge was said to be to create a hybrid design that incorporates the benefits of layer overlapping, while reducing unnecessary complexity and making the technology more cost-affordable for customers. This was achieved by overlapping layers in each semi-deflector, using a single cone. The highly efficient design of the 800 Series Hybrid is said to reduce cost and size, as opposed to other methods of overlapping layers. (Guill Tool & Engineering)
