Quality Control for Manufactured Weight Plates

The study aims to prove the need for higher quality production of weight plates which fall under US6746380B2 (expired May 10, 2021), assigned to USA Sports Inc. Literature justifies quality control standards. Selected literature validates posed hypotheses, and a product study is completed using weight plate specimens selected for physical quality testing to prove the common (repeated offense) existence of weight plates which fall out of the designated weight tolerance. Findings of physical product testing are collected and set against each other to determine differences in levels of quality control. Through extensive product testing (quantified within the study’s research methodology), novel quality control ideals are identified for product improvement in the study’s recommendations. Next steps are suggested to improve the understanding and utilization of quality control to work toward creating a sustainable and consistently high-quality product. Findings from the study are available to be used amongst companies in the fitness industry who produce weight plates.
