Typical Application Examples
The elastic strip forming mold works at ℃. The original 3-steel die-casting mold has a low service life because the elastic strips produce scratches and pull marks, which affect product quality. After switching to steel, The mold has stable dimensions, good heat resistance, wear resistance and thermal hardness, and its service life has been increased from the original 3~ pieces to 3~ pieces.
