THERE ARE FOUR WAYS TO PRINT ON PLASTIC:
1. Laser marking
2. Screen Printing
3. Heat transfer
4. UV Inkjet printing
But if you want to achieve a permanent clear effect laser marking is the most appropriate one of processing technology.
Because if you use screen printing, heat transfer, or ink-jet printing process is not enough environmental protection, screen printing of defective products, the mark is not clear, quality assurance needs to increase the strength of inspection, and it is difficult to adjust to better results, long-term use is also prone to Burr, fuzzy, broken lines and other situations, a waste of human and material resources, costs remain high.
The laser is an excellent solution to this problem, laser marking has never faded and does not fall off the effect, has zero consumables pollution-free, has low operating costs, and environmental protection, and is widely used by businesses.
The principle of laser marking is through the laser beam in various material surface markings. The effect of marking is to expose a deep layer of material by evaporation from the surface, to make a mark by causing a chemical or physical change in the surface material by the energy of light, or to burn off some material by the power of light, show the pattern or text to be etched.
Laser marking can print various characters, symbols, and patterns on the surface of plastic products. Even very small plastic products can be conveniently processed by laser, it can be used to mark all kinds of text, LOGO, product numbers, serial numbers, production dates, barcodes, and so on, and the product number, serial number, or date, time can automatically jump number, very practical and environmental protection.
ADVANTAGES OF LASER MARKING
- Contactless marking of plastic parts
- Suitable for soft, rough, tiered, or curved surfaces
- Marking without printing ink and solvents
- No pre-treatment of plastic parts
- Maximum flexibility for complex and fast-changing layouts
- Wear-resistant, chemical-resistant, and light-resistant
- Product safety is ensured by lasting and forgery-proof labeling
- High processing efficiency, computer control, easy to automate
- Personalization
THE APPLICATION OF DOME LASER MARKING ADDITIVES:
Most general-purpose plastics and some engineering plastics, such as PP, PE, PVC, PBT, PET, PA, ABS, POM, PS, PC, TUP, Pus, and Eva, can also be used for plastic alloys, such as PC/ABS, etc. laser marking clear bright handwriting, can be marked with black, white handwriting.
Amount added: 3-5/1000, depending on the transparency of the plastic and the color of the mark for black, white, and gray. According to the different plastic raw materials provided by manufacturers, the company can give the recommended formula to match it, in order to achieve the best effect of laser marking on plastic.
Suitable for laser marking machine light source type and wavelength range: CO2 Laser, Ray Laser, Nd solid laser, infrared laser, wavelength range: 308-1064nm.
Can be identified in: natural color plastic, white plastic, colored plastic, and black plastic laser printing label has been successfully commercialized applications including livestock ear, light switch cover, cosmetic packaging materials, ABS keyboards, HDPE, viz., PET and PVC rigid containers and container lids for automotive interior buttons and door knobs, dashboards, commercial machinery, nylon and PBT electrical connectors for automotive and non-automotive applications, hood components such as safes and air caps, anti-counterfeiting labels, container latches, stationery, appliance shells and so on.
