Guill Tool & Engineering, a manufacturer of extrusion tooling for the global market, has opened an in-house rheology laboratory at its facility in West Warwick, RI. The testing equipment includes a hybrid rotational rheometer, differential scanning calorimeter and thermal conductivity meter.
Third-party testing facilities typically are inexperienced in extrusion processes, said the company. By contrast, Guill not only can gather data similarly to third-party testers, but it has the expertise to interpret data as it applies specifically to extrusion. Guill is now equipped to test its customers’ materials and work with them to create compatible extrusion tooling that will give them a competitive edge.
Accurate 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, according to Guill. In-house testing also accelerates turnaround time on test results, reducing delays during the tool design process and improving control over processes and test parameters.
The new rheology lab processes standard materials and custom formulas and is equipped to mix materials, including 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 lab is available to extruders and chemical formulators, among others in the industry.
