Perspex is a brand name for very high quality acrylic sheets. The manufacturer makes these sheets to very high standards. Items made of acrylic sheets are used in a wide range of applications. Acrylic items can be manufactured in factories similar to plastic items but some applications require custom designed acrylic sheets. Such items are prepared with the help of laser cutting machines. There are many benefits of Perspex laser cutting service. The item prepared through this process has very smooth edges. There are no signs of burrs, deformity, colour change, burn marks or scratches. Because of these advantages, the custom-designed acrylic item can be used even in premium commercial applications.
Laser cutting service for Perspex is available on all range of its acrylic sheets. Many manufacturers have very large cutting machines with cutting bed that can measure as high as 2400mm x 1200mm. The powerful laser is able to cut up to 25mm thick Perspex sheet. Raster engraving and etching services for acrylic sheets measuring up to 1200mm x 700mm are available. Customers in need of further polishing can ask for diamond and flame polishing services. The cutting laser machine operates automatically after the CAD file of the artwork has been uploaded to its computer system.
There are different types of lasers used for this purpose. The CO2 laser melts, burns or vaporises the material to cut the sheet. Very fine detail and cutting quality can be achieved due to very narrow beam of the laser. The laser in the cutting machine is reflected off several mirrors before it is narrowed down in a finely focused beam. This sharp beam is used to cut or engrave material surface. The first step in the Perspex cutting process is to prepare the artwork. The vector artwork should only have the outline of the artwork. The outline should be in hairline thickness or thinner than that. The material and artwork are checked by the service company technicians. If everything is correct, the next step of laser sheet cutting process is initiated.
A protective backing is placed to protect the Perspex sheet surface from the burn and heat marks. Once the cutting process is complete, the residual protective backing is peeled away. The sheet is placed on the machine bed and its cutting system is configured for the artwork. The machine’s speed, frequency and power are adjusted to the type of acrylic sheet being cut or engraved. The machine cuts the Perspex sheet as per the outline strokes of the drawing.
Perspex laser cutting service can be used to cut small, medium, large or very large acrylic sheets. A laser cut gives the end item very high quality finish. There is no loss of transparency, colour and smoothness of the sheet. A Perspex sheet is a durable material for making products like store display systems and outdoor signage. It does not lose its quality, colour and properties even after stored in the harsh outdoor conditions for years.
