Acrylic (PMMA, polymethyl methacrylate) is a transparent, strong and easy-to-process thermoplastic plastic that is widely used in various industries due to its excellent physical properties and aesthetics. The following are common acrylic products:
Advertising signs: including store signs, signboards, light boxes, display stands, POP displays, etc.
Office supplies: such as business card boxes, file racks, pen holders, display boards, medals and trophies, etc.
Home decoration: photo frames, decorative paintings, vases, storage boxes, bathroom supplies, etc.
Retail displays: cosmetic display stands, jewelry display stands, product price tags, sample display boxes
Industrial accessories: instrument panels, equipment observation windows, control buttons, signs and nameplates
Electronic products: mobile phone holders, tablet computer holders, LED lampshades, display housings
Crafts: carved artworks, souvenirs, customized gifts, wedding supplies
When laser engraving or marking on acrylic products, the following are usually marked:
Brand logo: company logo, brand name, trademark and other visual identification elements
Product information: model, specification, material, production date, batch number, etc.
Instructions: operating guide, precautions, safety warnings, etc.
Serial number: unique identification code, anti-counterfeiting code, traceability code, etc.
Decorative patterns: artistic patterns, personalized designs, commemorative text
QR code/barcode: used for product tracking, marketing interaction or information query
Functional marking: scale lines, positioning marks, alignment instructions, etc.
Fiber laser marking machine has a significant advantage in marking and engraving acrylic materials due to its unique technical characteristics.
1. High-precision processing capability
The diameter of the fiber laser beam is extremely small (up to 20μm), which can achieve ultra-fine marking on acrylic materials, suitable for processing requirements of complex patterns, fine text and micron-level precision. This precision is particularly suitable for marking high-end electronic product accessories and precision instrument panels.
2. Non-contact processing
Laser processing does not require physical contact with the material surface, avoiding the problems of acrylic cracking, deformation or stress concentration that may be caused by traditional mechanical engraving, especially for the processing of thin acrylic plates. It is safer and more reliable.
3. Excellent edge quality
The engraving edge produced by fiber laser on acrylic is smooth and burr-free, and no secondary processing is required. Compared with CO2 laser, the heat-affected zone produced by fiber laser is smaller, which reduces the melting edge or atomization phenomenon of acrylic due to thermal effects.
4. Excellent contrast performance
By precisely controlling the laser parameters, an ideal light and dark contrast effect can be produced on transparent or colored acrylic. Especially when engraving on the back, it can form a unique three-dimensional visual effect, which is widely used in light guide plates, decorations and advertising logos.
5. High-efficiency processing speed
The marking speed of the fiber laser marking machine can usually reach more than 7000mm/s, which greatly improves the production efficiency of acrylic products and is suitable for the rapid delivery of large-volume orders. The adjustable pulse frequency makes it adaptable to the processing needs of acrylics of different thicknesses.
6. Wide material adaptability
The same fiber laser equipment can handle the marking needs of transparent, translucent and various colored acrylics without changing equipment or adjusting parameters significantly. It can also adapt to the marking of composite materials of acrylic and other materials.
7. Environmental protection and energy saving characteristics
Compared with traditional processing methods, the fiber laser marking process does not produce pollutants such as dust and wastewater, and has low energy consumption (generally the power of the fiber laser marking machine is between 20W-50W), which meets the environmental protection requirements of modern manufacturing industry.
8. Long-term marking effect
The mark formed by the laser inside the acrylic will not fade due to daily friction, cleaning agent wiping or environmental changes, and has excellent durability. The anti-ultraviolet property is also better than ink printing, which is suitable for acrylic products used outdoors.
9. Flexible automation integration
The fiber laser marking machine can be easily integrated into the automated production line, and can be used with a robot or conveyor system to achieve online marking of acrylic products, meeting the production needs of Industry 4.0.
