Extrusion 1-2019

54 kompakt Extrusion 1/2019 In order for a manufacturer to select the measurement and control solution X-Ray Measurement Technology for Single and Multilayer Products S has especially been developed for any kind of foamed pipe, vulcanized pro- ducts, hydraulic hoses, etc. RAYEX ® S measures and controls diameter, ovality, wall thickness and eccentricity of single and multilayer products with up to four layers. It provides precise measuring va- lues and highest reliability for pipe and hoses with an outside diameter of up to 80mm. The system features the latest X- ray technology and software solutions. In combination with the data acquisition and processor system, an automatic con- trol of the line is possible. By controlling line speed or extruder speed the parame- ters are controlled to the nominal value. The display shows all measurement values numerically and graphically as Measuring unit RAYEX ® S with the best price-performance ratio, the suitable technology must be chosen.

This was achiev- ed by overlapping layers in each semi-de- flector, using a single cone. The highly efficient design of the 800 Series Hybrid reduces cost and size, as opposed to other methods of overlapping layers. Essential benefits of the 800 Series Hybrid include eliminating weld lines in materials through patent- ed overlapping technology, pro- ducing a more consistent fi- nished product; reduced sensiti- vity to changes in viscosity; re- duced 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; low residence time; compact design and a low toleran- ce stack-up error factor, all resulting in improved concentricity. The 800 Series Hybrid extrusion tool greatly reduces stagnation, because overlapping layers are more inherently balanced than single layers and also be- cause each semi-deflector is “tuned to Guill announced the introduction of a new version of its popular 800 series, known as 800 Series Hybrid. In some ex- trusion applications that utilize cross- heads 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. Ad- ditional errors include difficult-to- process materials and demanding appli- cations where there is zero fault toler- ance. Seeking to design the next generation multi-layer die to overcome these chal- lenges, the engineers at Guill looked for a way to incorporate this technology into an updated version of the 800 Series. This led to the creation of the 800 Series Hybrid. The inherent benefits of the 800 Series are retained, including compact design, low residence time and a com- mon deflector bore that eliminates toler- ance stack up. The challenge was to create a hybrid design that incorporates the benefits of layer overlapping, while New 800 Series Hybrid Extrusion Tooling announced flush.” Conventional deflectors must si- multaneously achieve a balance between flushing, balancing and eliminating the weld line. There is less difference be- tween the slowest moving material and the fastest moving material in the deflec- tor channels, thus making the viscosity more consistent in the deflector.
