UV laser marking on plastic is a process of labeling or engraving plastic materials with the help of a UV laser beam. UV laser marking is a non-contact, non-destructive process that can produce high-quality and permanent markings on various plastic materials.
The markings made are exact, accurate, and have high contrast. The following sections will discuss the advantages, applications, types of lasers used, process, and safety measures for UV laser marking plastic.
UV laser marking is a process of labeling or engraving plastic materials with the help of a UV laser beam. The UV laser beam is focused on the plastic material’s surface, resulting in a localized reaction that produces high-quality and permanent markings on the fabric.
The UV laser beam creates a very high energy density, which causes the plastic material to melt, vaporize, or undergo a chemical reaction, resulting in permanent markings on the fabric.
There are several advantages of using UV laser marking on plastic materials. Some of the benefits are as follows:
UV laser marking on plastic materials has various applications in the manufacturing and industrial products industry. Some of the applications are as follows:
Two types of lasers are used for UV laser marking on plastic materials – solid-state lasers and gas lasers.
Solid-state lasers are the most commonly used for UV laser marking on plastic materials. They generate a high-intensity UV laser beam using a crystal or glass medium. Solid-state lasers are compact, efficient, and have long lifespans, making them ideal for industrial applications.
On the other hand, gas lasers use a gas medium, such as argon or krypton, to generate a UV laser beam. Gas lasers are less commonly used for UV laser marking on plastic materials due to their low efficiency and high cost.
The process of UV laser marking on plastic materials involves the following steps:
UV laser marking on plastic materials can be hazardous if proper safety measures are not taken. Some of the safety measures to be taken are as follows:
To ensure successful UV laser marking on plastic materials, MAC LASER has summarized the following tips:
UV laser marking on plastic materials is a high-precision, high-contrast, and permanent marking process with various applications in manufacturing and industrial products. Manufacturers can achieve accurate and reliable markings on their plastic products by following proper safety measures and tips for successful marking.
Is UV laser marking on plastic materials safe for the environment?
Yes, UV laser marking on plastic materials is safe for the environment as it does not produce harmful chemicals or emissions.
Can UV laser marking on plastic materials be used for food packaging?
Yes, UV laser marking on plastic materials can be used for food packaging as it produces permanent markings that do not fade away quickly.
What is the maximum plastic material thickness that can be marked using a UV laser?
The maximum thickness of plastic material that can be marked using UV laser marking depends on the type of laser used and its power. Generally, solid-state lasers can keep plastic materials up to 3mm in thickness.
Today,we will recommend you RFH UV laser brand from China.
RFH UV Laser Marking Module used for paint stripping on plastic
To meet the market demand, RFH newly developed S9 series UV laser in 2020. Comparing with its kinds, S9 series UV laser features with rugged sealed cavity, extremely compact size, simple and robust, high stability, high efficiency, high reliability and excellent laser beam quality.Its compact design suggests no necessity in building big light path, which greatly reduces space and cost and makes it easy to be installed into UV laser marking machines. In addition, S9 series cavity structure is more stability and more excellent scalability, which means the same laser cavity can be produces multi-power lasers , and the stability of different power ranges is greatly improved
