Cost reduction of 50% through simplification of processing by converting from irregularly shaped castings to split plates.

Examples of cost reduction through the processing of plate materials rather than casting, depending on the production lot.

Cost reduction through segmented processing of aluminum castings (a shift in thinking) [Before Improvement] ● Machining was done on aluminum castings (AC4C) ● The lot size was 3-5 pieces, with outer circumference processing and hole drilling ※ Considering the quantity, too much time was spent on setup, which reflected in the price [After Improvement] ● Stopped integration and separated each plate for machining ※ Eliminated the time spent on setup, resulting in significant cost reduction Collecting standard machined parts for casting usually leads to cost reduction. In the case of this component, the relationship between lot size and setup time negatively impacted costs, making it more expensive, so we deliberately chose the standard method. I believe this is also one idea. Additionally, by reverting to standard machining, we no longer needed to use specialized machinery, allowing us to shorten delivery times as well. ● Cost reduction effect: Existing product was 120,000 yen ↓ 60,000 yen (50% cost reduction) ■ Key Point: It is commonly understood that casting requires fewer processing steps, but when the production lot is small, setup time counts as processing time, so we are focusing on this aspect.
