[Case Study] Prevention of Foreign Matter Contamination in Food Manufacturing Lines and Reduction of Inspection Work

A case where Nord-Lock washers were proposed to prevent the loosening and falling out of screws.

Here is a case where we proposed the "Nord-Lock Washer" to a food processing manufacturer. In the final stage of packing the manufactured liquid, screws used in the equipment line fell off and were shipped without anyone noticing, resulting in contamination of the product. After our proposal, there have been no signs of screw detachment, and the emergency measure of inspection work has been eliminated, leading to a reduction in the burden on the workers. [Overview of the Issue] ■ Screws used in the equipment line fell off and were shipped while contaminating the product without anyone noticing. ■ The issue was discovered by chance during an inspection at a retail store, leading to a halt in production and a recall of all products. ■ Since then, all areas with potential for detachment have been addressed with emergency measures. ■ The inspection work before starting operations has become an excessive burden, so we want to implement a fundamental solution. *For more details, please refer to the related links or feel free to contact us.
