Keep the protective masking on
Article: Laser Cutting Technical Help
As a general rule, the thicker the material you are using, the higher
the need for adjustments to your laser file. It is important to use a slower
cutting speed with thicker materials to eliminate the risk of smoke residue and
recommended that the paper or clear protective masking be left in place when
vector cutting. The masking protects the plastic from excessive burning. If
wrinkles or bubbles in the masking are present, it is important that the masking
be smoothed or removed before cutting. Gases trapped under the masking can
damage your work. Leave the protective covering we supply until the very last
moment of installation.
This image shows the protective covering left on the
letters until the last moment of installation.
When needed we may also apply an additional 2nd layered protective cover.
Occasionally, we may reverse cut the materials to protect the face panel gloss
or appearance. When this occurs, Experience shows that the most effective method
for vector cutting is to cut from the front to back. This requires the on-screen
image to be negative in order for the cut piece to be right reading and to place
the material in the laser bed face down. It also requires cutting directly on
the laser bed, not on a honeycomb insert. (When the laser hits the edges of the
honeycomb cells, it bounces back causing a pitting that may mark the surface of
the material it is in contact with.)
Whenever it is convenient, leave the
factory masking on the front surface and if good results are still not being
achieved, try spraying the bed with water to absorb heat before laying the
material face down with the masking on. If two passes still prove necessary,
adjust the first setting so the cut travels nearly all the way through the
substrate. The second cut, the one affecting the face of the material, should be
adjusted to a much cooler setting, just enough to cut through the remaining
substrate and cap.
mm start points. The designer team set an initial blast point at
zero millimetres x zero millimetres. This gives your graphic design control
incredible accuracy. Let us know if your design is intricate or requires
multi layer application. Because we use the zero, zero technique, you work
will be very accurate. You may also like to read about the kerf values for
high accuracy cutting.
The protective mask is left on around non cut areas during cutting.
If you watch the favourite video below, you will notice lots of sparks flying
away up and over the material, for this type of metal processing - cutting, a
softened water solution is used that protects the highly polished metal surface.
