What is regrind?
Regrind is plastic material recovered from runners, sprues, or rejected parts that is ground up and reused in the process of plastic injection molding resulting in last waste and better material utilization. The big caveat: regrind usage is carefully controlled. Regrind isn't automatically equivalent to virgin resin. Every time plastic is processed through the molding machine, it experiences heat and pressure which can affect the polymer. At ADC we have carefully controlled regrind percentages if used in molding.
