X Regrind Usage for TY27MX

Abstract

TY27MX is a high-runner catalog from ABB Caribe. Since the first quarter of 2020, high levels of scrap were detected at the production line caused by process variation and inherent conditions. Resin X regrind usage was selected as the best method to achieve scrap reduction of 15% and optimize material consumption. A regrind material validation was performed in order to assure catalog’s functional performance and acceptable quality criteria. Internal quality procedure establishes that all parts must comply with RBT, Tensile Strength and Insertion Force specifications. A total of 48 parts per hour (3 hours total) were tested representing the molded full shot. RBT results were favorable, with all parts complying with the 2.50% maximum criteria. Likewise, all parts performed successfully during tensile testing complying with the 120 pounds minimum requirement. Also, insertion testing was positive with all parts complying with 6.00 pounds maximum force. Since TY27MX’s properties were not compromised with the material mixture, regrind usage can be used permanently as part of the process. Key Terms ⎯ Insertion, RBT, Regrind, Resin X, Tensile, TY27MX.
