【Carbon Neutrality Case Study】 Replacing parts originally made of high-tensile strength steel (590 material) with high-strength aluminum for carbon neutrality: A challenge towards weight reduction. This results in a 60% weight reduction compared to high-tensile materials. If processed at room temperature, the material would crack and be unprocessable. However, by focusing on the aging characteristics of duralumin, a processing method was developed that improves formability while maintaining material strength, successfully allowing for product processing. Nonetheless, there are still many challenges, such as determining the processing limits for each method, and evaluating the precision and strength of the products, especially since cracks can occur during bending if the bending radius is too small.

Press-formed product: A component that was joined by welding two parts is now completed as a single press-formed part. Old method: Stamped part + Stamped part ⇒ Joining process New method: Stamped part, only one component By completing the process in just one press operation, CO2 emissions are reduced by 62.9%. We have proposals to solve our customers' problems with our technical capabilities towards carbon neutrality.

Successfully performed processing without installing heating and cooling devices in the mold. Conducted blanking using CFRTP and carried out molding after heating. The transportation from heating to the mold will be a challenge moving forward.

Conventional: Products that were assembled by welding drawn parts and pipe tubes New method: Products realized solely through press processing (deep drawing) from sheet material

• others

Achieving net shaping of plate forging processing with cutting-less technology Thickness variation of up to 4mm through plate forging with material addition and reduction Enables approximately 30% cost reduction compared to conventional forged + machined products

We would like to introduce a case study of deep drawing press processing using ultra-high strength materials. The metal press "deep drawing processing" technology is a method that our company excels at. By producing all the molds in-house, we can reduce the initial costs for our customers' development.
