Hybrid Extrusion Tooling

A new version of the 800 series, known as 800 Series Hybrid, seeks to overcome the challenges associated with standard extrusion applications such as difficult-to-process materials and demanding applications where there is zero fault tolerance. The challenge was to create a hybrid design that incorporates the benefits of layer overlapping while reducing unnecessary complexity and making the technology more cost-affordable. This was achieved by overlapping layers in each semi-deflector, using a single cone.

Features of the 800 Series Hybrid include eliminating weld lines in materials; reduced sensitivity to changes in viscosity; reduced sensitivity to changes in line speed; myriad material and multi-layer application possibilities; works in all tubing and jacketing applications with a wide range of materials; and more.

The 800 Series Hybrid extrusion tool reduces stagnation since overlapping layers are more inherently balanced than single layers and also because each semi-deflector is “tuned to flush.” Conventional deflectors must simultaneously achieve a balance between flushing, balancing, and eliminating the weld line. There is less difference between the slowest moving material and the fastest moving material in the deflector channels, thus making the viscosity more consistent in the deflector.
