Tips for Using a Laser to Cut Plastics.
When cutting acrylic for signs, display systems or other advertising and
marketing display stands, you can improve your immediate quality with the
following tips. Also available corrugated plastic signs that can be cut into
The laser output needed depends on the thickness of the acrylic sheet and the
productivity required. The higher the laser output available, the faster the
acrylic can be cut
In principle it is very easy to cut acrylic. Generally speaking, the maximum
laser output is set and the speed is adjusted so that the material is cut
through. High-quality cutting results, however, can only be achieved with
carefully selected parameters.
At slow speeds, the cut edges achieved are rather
more polished. However, if cutting is too slow, the resulting cut is wide and
extends outwards towards the bottom. However, this also depends on the point of
focus and the focal length used. Use a focal length of 2.5 inch for thicknesses
between 3 and 8 mm, for thicker materials the focal length set should be 5 inch.
The focus should not lie on the surface but approximately a third of the way
inside the material. Striation increases with speeds that are too high. The gas
flow should be set as low as possible to achieve the best possible quality.
However, a higher gas flow allows faster cutting speeds.
Tips for cutting acrylic.
The acrylic used is also very important. Acrylic may be cast or extruded. Cast
acrylic is excellently suited to laser cutting. With extruded acrylic, the cut
edges become milky after cutting due to the stresses released. It is also
important to achieve clean adjustment of the beam since the cut edges are not
vertical if there is any astigmatism and exhibit different angles depending on
the direction of displacement. Therefore, the selection of a laser source with
good beam quality is particularly crucial.
Also, it is particularly important to prevent reflections of the laser beam as
far as possible since they cause visible unevenness in the cut edges. For this
reason, the material may not lie completely flat on the processing surface. Use
a special cutting table for this purpose. As a result the beam will barely be
reflected and you will get clean-cut edges.
Some jobs where a lot of cap material is being removed become coated with dust
and residue. This can happen on pieces that contain large open areas of text or
graphics, or on jobs where a lot of detail is being removed all across the
surface, particularly as seen in photo laser engraving.
These dust particles can
smear into the substrate and ruin the job if they are wiped with a dry or, even
worse, a wet cloth. This dust contains colorants and is so fine that when mixed
with any fluid almost immediately turns into a kind of paint. The best way to
eliminate the dust without ruining the background is to place transfer or
masking tape over the entire surface. Press it down and squeegee it in place
several times. Peel it off, and the dust particles will adhere to the masking.
Usually after one application of the masking, the sign can be cleaned using a
spray cleaner and cloth. On some jobs, especially photos, two or three
applications of masking may be necessary.
Laser Cutting Colored Acrylic or Colored Panels
Your choice of color can also affect laser settings. Some colors (such as blue
or red) contain more pigment. Depending on the size of your graphic, WE may have
to adjust your path directions and cutting speed setting to achieve the cleanest
marking possible. Call our sign designers anytime for advice.
Quality, speed and precision are the focal points behind every part we cut.
Laser cutting should not stress or distort materials, allowing your components to
maintain their strength and durability. Call us anytime for advice on laser
cutting for the signage industry. WE CAN CUT EXPERT SHAPES AND LETTERS Computer
