Slivers are the result of the aluminum interfacing with the cutting sections or punches.
Die cut aluminum sheet.
Improper clearance will reduce the die service life or burrs and lead to secondary cutting the irregular opening will increase the demounting force etc.
Aluminum is non magnetic and provides good thermal and electrical conductivity.
To reduce the production of slivers the severity of friction at the point where the two surfaces interface must be reduced.
The cutting surface of the die is the edge of hardened steel strips known as steel rule.

Die cut products stocks a variety of aluminum grades and tempers such as h12 h14 h19 t2 t4 and many others.
Besides the die clearance is subject to the material and thickness generally for carbon steel plate 12 18 of the thickness is best.
Aluminum can be anodized to strengthen its corrosion resistance create a harder surface and provide a decorative finish when appearance is necessary.
This weakens the aluminium and creates a fracture line.
These steel rules are usually located using saw or laser cut grooves in plywood.
Instead we recommend using a diamond blade that s rated to cut ferrous metal.
With the aid of a straight edge and a sharp knife score both sides of the aluminium sheet.
Steel rule die also known as cookie cutter dies are used for cutting sheet metal and softer materials such as plastics wood cork felt fabrics and paperboard.
