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

We would like to introduce a case where the manufacturing method was converted from die-cast parts to pressed parts. Aluminum is characterized by being lighter than iron products, contributing to the weight reduction of automotive parts. It was developed with the aim of achieving even greater weight reduction than die-casting. 【Technical Overview】 ■ Conversion from die-cast parts to pressed parts ■ Developed with the aim of weight reduction ■ Contributes to the weight reduction of automotive parts *For more details, please refer to the PDF document or feel free to contact us.

【Carbon Neutrality Case Study】 Replacing parts originally made of high-tensile strength steel (590 material) with high-strength aluminum for carbon neutrality: A challenge for weight reduction.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

We would like to introduce a case study of deep drawing press processing using SAPH440 material. The metal press "deep drawing processing" technology is a method we excel at. Production is carried out using hydraulic presses and general-purpose crank presses. By producing all the molds in-house, we can reduce the initial costs for our customers' development. At Higuchi Manufacturing, we undertake everything from "ultra-deep drawing press processing of SAPH440 material" to parts manufacturing and production equipment related to molds. 【Technical Overview】 ■ SAPH = Hot-rolled steel sheets for automotive structural use (JIS G3113) are materials originally used for automotive frames and suspensions, maintaining high strength even with a thickness of 2.0mm. ■ The (total length ÷ outer diameter) ratio secures dimensions of over 300%. ■ All molds produced are made in-house. ■ It is possible to reduce initial costs in development. *For more details, please refer to the PDF document or feel free to contact us.
