- FY2026AdvancedAnnual report
「We achieved automation by designing dedicated resonant anvils and developing a mechanical structure that suppresses vibration transmission. Compared with equipment that welds individual terminals, the cycle time has been reduced, the process is now almost fully automated with no need for human intervention, and dissimilar-metal bonded busbars can be supplied at lower cost.」
The company states that it developed equipment to almost fully automate ultrasonic bonding of dissimilar metals for EV busbars, achieving shorter cycle times and lower costs. - FY2024AdvancedAnnual report
「To address the expected further growth in demand for lithium-ion batteries and the need for lower prices as the electric-vehicle market expands, we have worked on ultrasonic bonding technology for battery busbars, joining dissimilar metals such as copper and aluminum, as well as full automation. We produced prototypes and a development model of a fully automated system and are conducting high-volume trials.」
For EV battery busbars, the company is advancing ultrasonic bonding of dissimilar copper and aluminum metals and full automation, and has progressed to the mass-production validation stage using prototypes and fully automated equipment. - FY2022AdvancedAnnual report
「We participated in the development of AGVs for the automated transport of completed vehicles and developed wire harnesses, high-voltage power cables and power boxes for high-output power distribution to efficiently connect all power, signal and CAN circuits.」
In wire-harness-related operations, the company is expanding its development scope to products supporting EVs and automated transport, including AGVs, high-voltage power cables and power boxes. - FY2021AdvancedAnnual report
「We completed the development design of three types of EV power boxes, two for two-wheel vehicles with stringent vibration and waterproofing requirements and one for outboard motors. In addition, regarding connection, the primary function required of wire harnesses, we developed a new connection component using an ultrasonic welding process that reduces contact resistance to the minimum and eliminates current loss. It has been adopted for marine products.」
Development design of three EV power box models was completed, and connection components using an ultrasonic welding process were adopted for marine products. Wire-harness-related development has progressed to a stage close to mass production and customer adoption. - FY2020AdvancedAnnual report
「For the EV junction block units, two-wheel vehicle fuse boxes and CAN control units for which development began in the previous fiscal year, we have entered the mass-production preparation stage.」
Development of EV junction block units and other products has progressed to the mass-production preparation stage. - FY2019AdvancedAnnual report
「As part of these efforts, we promoted the design, evaluation and proposal of harness component parts. During the current fiscal year, amid the shift toward EVs, adoption was decided for several relatively large unit components, including EV junction block units, fuse boxes and CAN control units, and development is under way.」
Customer adoption was decided for several large unit components, including EV junction blocks, and development is under way. - FY2018First statedAnnual report
「As part of these efforts, we promoted the design, evaluation and proposal of harness component parts. During the current fiscal year, we developed 106 new projects, all of which were adopted and installed in customer products. We also began developing junction blocks for EVs in response to the shift toward EVs.」
The company developed 106 new harness component projects during the current fiscal year, all of which were adopted and installed in customer products, and disclosed the start of development of junction blocks for EVs.
