Core Functions and Advantages of the Curved Knife Die：
Excellent Anti-Interference Ability (Clearance): When a workpiece needs secondary or multiple bending operations (for example, making a box with four high sides, a deep U-shaped groove, or products with return flanges/dead edges), a standard straight blade punch will directly hit the already bent vertical edges. The bent blade/gooseneck die, with its recessed 'curved' shape, can perfectly avoid these obstacles.
