We successfully achieved cost reduction by producing a component, which previously required post-press cutting to create 0.35mm-deep grooves on the inner walls (0.7mm thickness) of a square-drawn part, using simultaneous press processing at 8 locations.

Additionally, the outer surface shows almost no traces of the inner groove processing, making it suitable for use as an exterior component.

Approximate dimensions: 45mm × 45mm, height 7mm
Material: Brass (C2680 1/4H)
