We would like to introduce a case of a cover that prevents scratches on the nut area during the cleaning of aluminum wheels for vehicles. In the past, we faced the issue of warping, which was unavoidable in non-mass-produced items, leading to significant deviations in dimensions and tolerances. There were concerns about whether we would need to create molds, which would incur substantial costs. Therefore, we considered the causes of warping due to "shrinkage differences" in conventional machining and employed our unique high-precision cutting technology to balance the "residual stress," which is the cause of the shrinkage differences. As a result, we were able to control warping in single-item machining and achieve dimensional tolerances in the 100-micron range. 【Overview】 <Challenges> ■ In non-mass-produced items, warping was unavoidable, leading to significant deviations in dimensions and tolerances. ■ Creating molds would incur substantial costs, making mass production necessary for profitability. <Solution> ■ By considering the yield point of the "residual stress," which is the cause of shrinkage differences, we achieved warping control in single-item machining using our unique high-precision cutting and processing technology. *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce an example of improvement of existing products based on our VA proposal. With conventional work supports, the weight was significant, making it impossible to remove oil, which led to quality issues in the next process. Both manual and machine operations experienced significant time losses during the attachment and detachment processes. As a solution, we improved the design to achieve significant weight reduction without compromising strength, allowing for oil removal. This not only enhanced quality but also made the attachment and detachment processes smoother, resulting in substantial time savings. [Overview] <Challenges> - Although there were efforts to improve the work supports, significant warping occurred, leading to a decrease in dimensional accuracy, which made us abandon the initiative. <Solution> - Thanks to Meisei's high-precision warping control technology, we were able to maintain dimensional accuracy while realizing the customer's ideal. *For more details, please refer to the PDF document or feel free to contact us.
