2t×D1×P3　60°Staggered
（Open Area 22.7%）		　SUS304L
6t×D3×P5　60°Staggered
（Open Area 32.6%）

Holes smaller than plate thickness can be punch-pressed,
reducing the cost even lower than that of the machining process!!

About

Enables punching holes of sizes smaller than plate thickness.
(Vertical and horizontal arrows are of the same length.)

Enables processing at a shorter pitch that has been conventionally impossible.With a given hole size, a higher strength can be obtained by using a thicker plate.
(Example)Stainless Steel Plate
Thickness: 2.5t　→　Hole Size: 1.5
Thickness: 3.0t　→　Hole Size: 2.0
