[Case Study] Cost Reduction through Changes in the Manufacturing Method of Mass-Produced Screws

A case where the manufacturing method was changed from cutting processing to forging processing, resulting in a 70% cost reduction in the customer's purchase price.

We would like to introduce a case where we proposed "reducing the manufacturing process and increasing production lots" to an industrial machinery manufacturer. The customer was purchasing low-head type special-shaped hexagon socket bolts M2 from an e-commerce site, but due to high unit prices and an increasing quantity needed, they expressed a desire to reduce costs. We proposed a change in the manufacturing method, which was adopted without any issues and was equivalent to or better than the conventional products, resulting in significant cost reductions. [Case Overview] ■ Issues - Costs had become excessively high - The shape was not particularly difficult to manufacture, despite being outside JIS standards ■ Requirements for Solving the Issues - Reduction of costly machining processes - Establishing a production lot that ensures stable lead times *For more details, please refer to the related links or feel free to contact us.
