We would like to introduce a case where our proposal led to the reduction of unnecessary processes and resources related to materials and plating treatment. As background, in the insert molding and assembly processes, we had to cut and discard part of the terminals to secure the necessary workspace. As a result, despite the terminals not being used, costs for materials and plating treatment were incurred, leading to higher manufacturing and plating costs than necessary. Therefore, we proposed a method to transfer the terminals to a different transport band after plating and re-crimp them in a manner suitable for the conditions of the subsequent process. This significantly contributed to the reduction of manufacturing and plating costs. **Features** - **Challenges** - Costs for materials and plating treatment were incurred despite the terminals not being used. - **Effects** - Achieved approximately 40% cost reduction compared to conventional methods. - Reduction of unnecessary processes and resources related to materials and plating treatment. - Enabled flexible responses to space constraints in insert molding and assembly processes. *For more details, please download the PDF or feel free to contact us.*

We will introduce a case study that achieved cost reduction and space-saving in the production of assembly equipment for electronic components and similar items. The challenges faced by our customer included the need for a significant initial investment of several tens of millions of yen per unit to introduce new assembly machines, which placed a heavy financial burden on them. Additionally, the requirement for installation space of about 8 to 10 meters per line posed significant challenges in terms of layout constraints and space allocation within the factory. By utilizing molds, we proposed a replacement for the conventional assembly machines. This allowed for more effective use of the limited factory space and enabled the establishment of a flexible system that can adapt to future line expansions and process reviews. [Case Overview] ■Challenges - The introduction of new assembly machines posed a significant financial burden. - There was a need for layout constraints and space allocation within the factory. ■Effects - Significant reduction in initial investment costs. - Improved flexibility in factory layout, contributing to space-saving. *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case where our proposed new method significantly reduced the area requiring gold plating. The customer faced a challenge where, amidst soaring gold prices, it was necessary to allow for margins in terminal design to accommodate post-plating insert molding and assembly processes. However, gold was being used in areas that were actually unnecessary, leading to plating costs exceeding expectations. To address this, we manufactured terminals while minimizing the margins and performed gold plating. After that, we implemented pitch conversion by crimping the terminals to a different band with a long pitch. This allowed us to limit the area requiring plating to the absolute minimum, significantly reducing unnecessary gold plating. 【Case Overview】 ■Challenge - Excessive plating costs due to rising gold prices. ■Effect - The proposed new method significantly reduced the area requiring gold plating. - Achieved approximately 50% reduction in gold plating costs compared to conventional methods. - Made a significant contribution to optimizing product costs while responding to rising gold prices. *For more details, please download the PDF or feel free to contact us.
