How to carve acrylic by laser
Acrylic materials are widely used. They are cheap and have good laser absorption rate. They can be used to make all kinds of products, including all kinds of signs, gifts and prizes. Most people usually choose transparent acrylic because it is very popular and easy to engrave.
Most of goods from our life need to mark or engrave logo,mark our own name to be original and exclusive.Such as a gift for a girlfriend,boyfriend,for mather or classmates,mark her name,then it will be specifically design for him.Brings happy.
So the laser marking machine going into our life daily,and becoming more and more generalization.
Howweld manufacturer have a small table type machine suitable for engrave gifts,small products,precisition products,watch,or mark logo on paper,iphone,mobile phone shell etc.With very good price.Fiber laser source.
To use laser engraving acrylic materials, we must first understand the general classification of the materials. Acrylic generally refers to thermal plastics made by various brands. Acrylic plate is divided into two categories: casting plate and extrusion plate according to the production process
1.Acrylic casting board: high molecular weight, excellent stiffness, strength and excellent chemical resistance. This kind of plate is characterized by small batch processing, incomparable flexibility in color system and surface texture effect, complete product specifications and suitable for various special purposes. (when laser engraving, cast acrylic will be transformed into the cold material pursued in many custom applications.
It can be molded into different shapes and sizes, and it is often used to make awards due to its good optical quality.)
2.Acrylic extruded plate: compared with cast plate, extruded plate has lower molecular weight and weaker mechanical properties. However, this feature is conducive to bending and thermoforming, and is conducive to rapid plastic vacuum suction molding when dealing with large-size plates.
At the same time, the thickness tolerance of extruded plate is smaller than that of cast plate.
It is easier to make extruded acrylic than cast acrylic, which makes extruded acrylic cheaper.
In addition, the extruded acrylic laser engraving is clean and smooth, and the edge is flame polished. Laser engraving products look very clear, not like the frosted appearance after casting acrylic engraving. It is also softer and easy to stick during rotary engraving.
The effect of laser engraving acrylic is the best at low power and high speed. If your acrylic material has a coating or other additives, please increase the power by 10%, but keep the speed of use on unpainted acrylic. This provides more energy for the laser to cut the paint.
The materials discussed will determine the ideal frequency setting for your laser. However, if cast acrylic is used, you can carve at a high frequency of 10000 – 20000 Hz, and if extruded acrylic is used, you may want to carve at a lower frequency of 2000 – 5000 Hz.
Lower frequencies result in lower pulses, increasing pulse energy or reducing constant energy in acrylic acid. This phenomenon results in less boiling, less flame and slower cutting speed.
