Testing & Quality Control

There are a wide variety of instruments used to maintain part quality in processing. Materials companies and compounders typically use rheometers, tensile testers and other laboratory instruments that help predict how its material will behave in the real world once it is made into a part. Compounders and processors alike rely on color-matching and formulation devices to keep quality consistent.
