Extrusion International 3-2023

22 Extrusion International 3/2023 INDUSTRY NEWS In-House Rheology Lab launched  Guill Tool, manufacturers of ex- trusion tooling for the global mar- ket, has opened an in-house rheol- ogy 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 facil- ity in West Warwick, Rhode Island, USA. The lab features several key machines that ensure optimum re- sults, when testing materials, espe- cially new compounds to be extrud- ed. 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 extru- sion processes. Guill, however, can not only gather data the same way third-party testers can, but can also interpret that data as it applies specifically to extrusion. Likewise, third-parties simply supply data, not recommendations. Guill is now equipped 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 reduc- es the number of physical reworks needed, as the tooling has a greater chance of producing a good prod- uct at the outset. In-house testing also speeds up the turnaround on test results, reducing delays during the tool design process and offering better control over the processes and test parameters. The new Guill rheology lab pro- cesses standard materials, custom formulae and it is equipped to mix materials. These materials include plastics, thermoplastic elastomers, all types of rubber and silicone. In- formation from the lab is transmit- ted directly to the Guill engineering department via computer link for review by the design team. The lab will be offered for use by extruders and chemical formula- tors, among others in the industry. Please contact Guill for full details.

Lines are installed in 3 different sites located in Europe and owned by major plastic processors. All projects comprise the engineering and subsequent construction, installation and start-up of turn-key lines dedicated to the recycling of polyolefin, either polypro - pylene or polyethylene, with different density and pos- sibility to add fillers and/or modifiers depending on the single set-up. The selected extruders have enhanced degassing sys- tems for efficient extraction of contaminants. The high torque of the extruders also provides an optimal fill - ing of the screw and therefore a maximum production output in the range of 2 to 4 tons per hour depend- ing on size of extruders, filtering tasks and type and/or density of the scrap. Single systems of the line are generally integrated into ICMA’s control panel, and all cabinets have remote con- trol gates for efficient post-sale service.
