Extrusion 4-2022

mendations. Guill is now equipped to both test its customer’s materials and work with them to create extrusion tool- ing that will give them a competitive edge. Accurate simulation and interpre- tation by extrusion experts greatly reduc- es 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, reduc- ing delays during the tool design process 57 Extrusion 4/2022 ➠ Guill Tool & Engineering www.guill.com Guill Tool, manufacturers of extrusion tooling for the global market, has open- ed an in-house rheology laboratory, mak- ing it the only extrusion tooling manu- facturer in the industry with such a capa- bility. Seeking to obtain better results and minimize the time it takes between test- ing and production, Guill built its own rheology lab in their facility in West War- wick, Rhode Island, USA. The lab featur- es several key machines that ensure optimum results, when testing materials, especially new compounds to be extrud- ed. The testing equipment includes a Hy- brid Rotational Rheometer, a Differential Scanning Calorimeter, and a Thermal Conductivity Meter. Third-party testing facilities are typically not experienced in extrusion 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 recom- In-House Rheology Lab launched and offering better control over the pro- cesses and test parameters. The new Guill rheology lab processes standard materials, custom formulae and it is equipped to mix materials. These ma- terials include plastics, thermoplastic elas- tomers, all types of rubber and silicone. Information from the lab is transmitted directly to the Guill engineering depart- ment via computer link for review by the design team. The lab will be offered for use by extrud- ers and chemical formulators, among others in the industry.
