Bending

• avoiding cracks and rupture

• reduce springback effect

• increase angle of bend

• reduce bend radius

Wire Drawing

Deep Drawing

• drawability

• depth of draw

• finish drawing

• influence material flow

Deep Drawing Tool

• diameter punch 48mm

• isolating layer on blankholder and die

Deep Drawing Dilas

• flat temperature profile

• limited temperature
