Acute Angle Die is a specialized tooling component used in metal stamping, punching, and press brake forming operations to create bends, cuts, or formed features with angles less than 90 degrees. Unlike standard dies designed for right-angle or obtuse-angle applications, acute angle dies are engineered to produce sharp, precise angles while minimizing material distortion and springback.
These dies are commonly used in industries where high-precision sheet metal fabrication is required, including automotive, aerospace, electronics, and industrial equipment manufacturing.
Acute Angle Die
An acute angle die works in conjunction with a punch to shape metal into a specific angle.
A sheet metal workpiece is positioned over the die opening.
The punch descends and forces the material into the die cavity.
The die controls the final angle and shape of the bend or formed feature.
After the punch retracts, the material retains the desired geometry.
Because acute angles generate higher stress concentrations than standard bends, die geometry must be carefully designed to ensure accurate results.
Different manufacturing applications require different die configurations.

When designing an acute angle die, engineers must evaluate several critical factors.
The selected angle directly affects:
Bend accuracy
Material flow
Springback behavior
The opening must match:
Material thickness
Required bend radius
Production requirements
Different materials respond differently during bending.
Examples:
Mild steel
Stainless steel
Aluminum
Copper alloys
Higher production volumes often justify premium tool materials and coatings.
Several variables influence the price of an acute angle die.
More intricate die geometries require additional engineering and machining.
Premium materials increase cost but improve lifespan.
Tighter tolerances require advanced manufacturing techniques.
Specialized coatings add cost while extending service life.
Larger orders typically reduce the cost per unit.
