Extrusion International 6-2021

27 Extrusion International 6/2021 Guill Tool & Engineering www.guill.com In-House Rheology Lab launched „ Guill Tool, manufacturers of extrusion tooling for the global market, has opened an in-house rheology laboratory, making it the only extrusion tooling manufacturer in the industry with such a capability. Seeking to obtain better results and minimize the time it takes between testing and production, Guill built its own rheology lab in their facility inWestWarwick, Rhode Island, USA. The lab features several keymachines that ensureoptimum results, when testingmaterials, especially newcompounds to be extruded. The testing equipment includes a Hybrid Rotational Rheometer, a Differential Scanning Calorimeter, and a Thermal Conductivity Meter. Third-party testing facilities are typically not experienced in ex- trusion processes. Guill, however, can not only gather data the sameway third-party testers can, but canalso interpret that data as it applies speci fi cally to extrusion. Likewise, third-parties sim- ply supply data, not recommendations. Guill is nowequipped to both test its customer’s materials and work with them to create extrusion tooling that will give them a competitive edge. Accu- rate simulation and interpretation by extrusion experts greatly reduces the number of physical reworks needed, as the tooling has a greater chance of producing a good product at the outset. In-house testing also speeds up the turnaround on test results, reducing delays during the tool design process and offering bet- ter control over the processes and test parameters. The new Guill rheology lab processes standard materials, cus- tom formulae and it is equipped to mix materials. These materi- als include plastics, thermoplastic elastomers, all types of rubber and silicone. Information from the lab is transmitted directly to the Guill engineering department via computer link for review by the design team. The labwill be offered for use by extruders and chemical formu- lators, among others in the industry.

Of course perfect cleanliness is also essential for temperature regu- lation. The new low-leakage couplers fromMeusburger provide the optimal foundation for this. The new E 25... low-leakage couplers have a fl at-face valve on both sides. This ensures that no empty space is createdwhen de- coupling sonomedia can escape, which allows for cleanproduc- tion and user safety. The long pilot guarantees complete sealing and durability, and thanks to the O-ring seal on the fi tting, the coupler can be screwed in clean and quick – without any thread sealant at all. The low-leakage couplers are available with hose or quick- fi t nozzle and with thread in straight and 90° angled versions, available in the common nominal widths DN6 and DN9. Cou- plers with convenient one-hand operation engage automati- cally. The minimal pressure drop is due to the optimised fl ow geometry. Low-Leakage Couplers The standard version is already equippedwith special sealing for water up to 150° C and oil up to 200° C. The threaded version is also available in a high-temperature version with a turquoise ring for identi fi cation. The special FKM seals installed in them are specially designed for hot water up to 180° C and temper- ing oil up to 220° C and are extremely durable. This guarantees optimal process safety in the production.
