It is possible to process complex shapes with a multi-stage part former with up to 9 stages.
We provide cold forging processing of precision parts that enables high performance. By utilizing a layout and special mold structure, we achieve processing that is generally difficult. Additionally, our forging technology that exceeds limits reduces secondary processing and lowers processing costs. 【Features】 ■ A consistent production system with numerous dedicated machines that balances high quality and mass production. ■ An environmentally conscious processing method that minimizes material waste and reduces material costs. ■ Good surface roughness and minimal dimensional variation ensure stable press-fitting and assembly. ■ A thorough commitment not only to quality but also to appearance and tactile feel. *For more details, please download the PDF or feel free to contact us.
