Die-cutting capabilities
Possibilities to cut sizes according to customer specification
Maximum Dimension of a Die-Cut Piece:
240 mm (width) x 380 mm (length)
Minimum Thickness:
Obviously this is dependant on the "handle-ability" of a product but 0.012 mm polyester film has been processed without difficulty.
Maximum Thickness (cut to date):
Polyester Film : 0.250 mm
Aluminium Foil : 0.300 mm
Copper Foil : 0.150 mm
During the die-cutting of a thick product (i.e. + 0.100 mm) a characteristic curvature can occur. This can be particularly noticeable with a metal foil product.
Minimum Distance between Two Cutting Blades on Die:
1.5 mm - This distance equates to the minimum distance between any two die-cut areas.
Minimum Diameter of Circular Shapes:
Hole through a part: 1.5 mm
Dots: 3.0 mm
Typical Tolerances:
We quote a standard tolerance for our die-cut pieces of: +/- 0.2 mm.
However it is important to note that in many cases we can achieve a tolerance value better than this. Since each die-cut piece is individual then we can give very accurate tolerance values once the piece has been die-cut and evaluated.
90° Angles:
Due to the method of die-cutting tool manufacture, where die-cutting lines meet, it is impossible to achieve an exact 90o angle. A type of "radius angle" will always be produced.
Soldering Window:
We recommend the following minimum sizes for solder window:
Circle: 4 mm diameter
Rectangle: 3.5 mm X 5.0 mm
Minimum Outer Margin Dimension:
e.g. Copper foil 0.035 mm + polyester film 0.025 mm: 0.5 mm
For other foil/ film combinations the margin would have to be increased.
Forms of Die-Cut Pieces:
- Butt-Cut: a continuous line of rectangular/ square die-cut pieces with no spacing between the pieces supplied on an interliner
- Individual Die-Cut Shapes on a Roll: a line of individually separated die-cut shapes supplied on an interliner in roll form
- Chopped Pieces: die-cut pieces supplied individually not in roll form, (e.g. A4 sheet)
Maximum Width of Printing:
236 mm
Maximum Print Repeat Length:
300 mm
Scored Interliner:
Where individual pieces are supplied on an interliner, the interliner can be scored. This allows partial removal of the interliner to expose the die-cut piece. This will facilitate the easy removal of the die-cut piece.
