This catalog is a collection of case studies aimed at customers facing management and cost challenges related to multi-process (using multiple presses). It includes topics such as "integration of multiple parts," "part distortion due to heat treatment processes," and "outsourcing management of multiple processes." We have also received positive feedback regarding quality control and significant cost benefits. We encourage you to take a look. 【Contents】 ■ Issue 1: <Multiple press processes for a single product> ■ Issue 2: <Material costs and machining costs as a percentage of product cost> ■ Issue 3: <Work time and cost issues for processing multiple holes> ■ Issue 4: <Integration of multiple parts> ■ Issue 5: <Part distortion due to heat treatment processes> ■ Issue 6: <Machining time> ■ Issue 7: <Lead time and cost for prototype creation> ■ Issue 8: <Outsourcing management of multiple processes> *For more details, please refer to the PDF document or feel free to contact us.

The customer was facing issues with cost, quality, and production capacity due to the use of multiple presses for production. Therefore, we proposed completing the forged products in one stroke using our AIDA UL2000 ton press. By feeding the material into the press entrance, the finished products can be discharged from the press exit, allowing for improvements in quality (including slit holes and engraving processes), cost, and lead time. 【Case Overview】 ■Challenge: Production using multiple presses led to issues with cost, quality, and production capacity. ■Solution: Completion using the AIDA UL2000 ton press. ■Effect: Improvements were achieved in quality, cost, and lead time. *For more details, please refer to the PDF document or feel free to contact us.

Are you concerned about the rising material costs and cutting costs that affect product costs due to global material price increases? Our company can reduce cutting costs and input material costs by decreasing the volume of materials used through our unique cold forging technology, which allows for quality shape changes within a single stroke. By improving material yield through forging shape changes, we can reduce both material costs and cutting costs (shortening cutting time). 【Overview】 ■ Issue: Material costs and cutting costs in product costs ■ Solution: Improvement of material yield through forging shape changes ■ Effects: Approximately 15% increase in material yield Reduction in both material costs and cutting costs (shortening cutting time) *For more details, please request materials or view the PDF data available for download.

The customer was struggling with significant work time and costs arising from processing multiple holes. Our forging press achieves the processing of closely spaced multiple holes in a single stroke. As a result, we were able to produce multiple holes with high quality in the forging process, significantly reducing work time and leading to substantial cost reductions. 【Case Summary】 ■ Issue: Significant work time and costs incurred in processing multiple holes ■ Solution: Achieved processing of closely spaced multiple holes in a single stroke with a forging press ■ Effects: - Produced multiple holes with high quality in the forging process - Significantly reduced work time and achieved substantial cost reductions *For more details, please refer to the PDF document or feel free to contact us.

The customer was troubled by excessive processes, costs, and the effort required for corrections due to core runout caused by the two-part configuration. Therefore, we proposed the integration of the two parts using work hardening through cold forging. As a result, we achieved multiple improvements, including reductions in cost, weight, elimination of heat treatment, process reduction, and the elimination of correction work due to excellent concentricity. 【Case Overview】 ■ Issue: Excessive processes, costs, and effort for corrections due to core runout caused by the two-part configuration. ■ Solution: Integration of the two parts using work hardening through cold forging. ■ Effects: Achieved multiple improvements such as reductions in cost, weight, elimination of heat treatment, process reduction, and elimination of correction work due to excellent concentricity. *For more details, please refer to the PDF document or feel free to contact us.

The customer was troubled by distortion caused by heat treatment. Therefore, we proposed the abolition of heat treatment and a switch from hot forging to cold forging. As a result, they were freed from the need for full inspection due to heat treatment distortion. 【Case Summary】 ■Issue: Distortion due to heat treatment ■Solution: Abolition of heat treatment and switch from hot forging to cold forging ■Effect: Freed from full inspection due to heat treatment distortion *For more details, please refer to the PDF document or feel free to contact us.

The customer was troubled by the costs incurred from the working time due to full cutting. Therefore, we proposed a near-net shape unique to ultra-precision cold forging. We achieved high precision and eliminated partial cutting in the cold forging process. As a result, we were able to find a reduction in total costs for products that can be handled by cold forging. 【Case Summary】 ■Issue: Working time from full cutting = Cost ■Solution: Near-net shape unique to ultra-precision cold forging ■Effect: Found a reduction in total costs *For more details, please refer to the PDF document or feel free to contact us.

The customer was struggling with whether to create molds for prototypes based on different conditions or to prepare them using full machining, which would require a lot of money and time, as part of the pre-mass production stage. Therefore, we proposed the production of prototype workpieces from stock materials. Using a 6kw laser, we provided prototype workpieces (a small number of various types with a 1mm difference) immediately. As a result, we were able to reduce the costs of prototype molds and lead times. 【Case Summary】 ■Issue: Struggling with prototyping as a pre-mass production stage ■Solution: Produced prototype workpieces from stock materials using a 6kw laser ■Effect: Reduced costs of prototype molds and lead times *For more details, please refer to the PDF document or feel free to contact us.

The customer needed to manage multiple outsourcing tasks and was facing challenges. Our company completes everything from materials to forging within a single factory. We can also handle each process individually. As a result, we have demonstrated the effectiveness of quality control and significant cost advantages, receiving positive feedback from our customers. 【Case Summary】 ■ Issue: Need to manage multiple outsourcing tasks ■ Solution: Complete everything from materials to forging within a single factory ■ Effect: Quality control and significant cost advantages *For more details, please refer to the PDF document or feel free to contact us.
