The 800 Series Hybrid, according to Guill, retains the benefits of the overall 800 series: compact design, low residence time and a common deflector bore that eliminates tolerance stack up. But company officials say the 800 Series Hybrid also boasts a hybrid design that incorporates the benefits of layer overlapping while reducing unnecessary complexity and making the technology more cost-affordable for customers.
The result is a more affordable smaller extrusion tool for producing overlapping layers — a method used to reduce errors from gels breaking through a thin wall, weld lines, inconsistent wall thickness, plus material and process variations, according to Guill.
Guill officials say the 800 Series Hybrid’s benefits include:
- Eliminating weld lines in materials through patented overlapping technology;
- Producing a more consistent finished product;
- Reduced sensitivity to changes in viscosity and changes in line speed.
Said Guill: “The 800 Series Hybrid extrusion tool greatly reduces stagnation, because 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.”
