Maximizing the value of regrind

摘要

With today's consumers demanding ever more sustainable, reused materials in end products, it's become ever more important to optimize resin usage - which means, in part, optimizing the use of regrind.Regrind is material that has undergone at least one processing method such as molding or extrusion, and the subsequent sprue, runners, flash, rejected parts, et cetera are ground or chopped. To develop a strategy that optimizes the value of regrind, it's important to know the issues involved. Appropriate shop floor procedures and discipline must also be in place to avoid potentially catastrophic results.
