PVT 500 This new testing apparatus from Goettfert can be used by plastics processors, including compounders and injection molders, to evaluate how various kinds of molten plastics will shrink in the mold; as an option, the device also can measure thermal conductivity. The device has a constant high piston force of 20 kilonewtons.
What’s new? The apparatus, which employs a technology that was formerly available only as an option on Goettfert’s capillary rheometer. The PVT 500 also employs a new, external cooling system.
Benefits Cost-effective materials testing and versatility. Goettfert says the instrument’s price compares favorably to other technologies. Also, the PVT 500 can handle temperatures of up 932 degrees Fahrenheit and, with the new cooling system, it can cool plastics from a molten state of about 400 degrees Fahrenheit to 345 degrees Fahrenheit in just one minute. By studying the effects of shrinkage, plastics processors can optimize their parts.
