Design & Production

By combining and leveraging our know-hows and state-of-the-art analyzing technologies accumulated over the years, we meet and exceed your expectations on highly rigid and functional die design. Dies are fabricated upon close consultation with our customers from die design stage and by utilizing CAE analysis. We also limit the lead time by conducting formability analysis to reduce the number of required die tryouts, for early start-up of production.
