UV Laser Marking Machine

UV laser printers make clear, easy-to-see marks that don’t fade, which is excellent for industries where tracking and safety matter most. These printers are used by makers of medicine, medical tools, and beauty products to keep codes readable from start to finish. They can mark soft materials gently, meet strict rules and keep products safe.

Product Information Overview

Precision UV Laser Marking for High-Quality Metal Surfaces

UV laser marking machines give noticeable and exact marks on metal, perfect for industries that need sharp and detailed ID. They use a short UV light that marks gently, even on coated or heat-sensitive metals. This makes neat, clean codes, logos, and text that are easy to read and stay for a long time.

PRODUCT OVERVIEW

The UV laser works at a wavelength that is one-third of the usual laser (1064 nm), putting it in the UV light range. It’s often called a “UV laser printer.” It’s also known as a THG laser, made by changing 1064 nm to 532 nm with a special crystal, then to 355 nm with another. Because UV light is easily absorbed and doesn’t create much heat, this process is called “cold marking.”

The laser’s light size affects how small the laser dot can be. UV lasers use a shorter light (355 nm), which helps the beam focus on tiny spots. This lets the laser make very exact marks, even on small or detailed parts of a product. That’s why UV lasers are great for fine marking without heat damage.

The shorter light wave makes a smaller laser point, helping the laser mark tiny or detailed spots very clearly. This makes UV lasers great for jobs needing tiny text, logos, or numbers in tight spaces, like in electronics, medical tools, beauty packs, or chip labels. They make clean, sharp, lasting marks without touching or heating, keeping even soft parts safe and strong.

Product Advantages

Industry trend

Makers of PET packaging now use “thin-walled” PET to save money and cut waste. But this thin material can easily burn or bend with regular laser marking. UV laser printers fix this problem by using soft, low-heat light to mark without harm. They give clear, correct marks while keeping the weak surface safe and damage-free.

Stricter rules for drug packaging and labelling have led many companies to switch from ink systems to laser marking. Laser marking helps them follow the rules, track products better, and keep packaging safe. This method also keeps labels clear and correct, making sure product details stay readable and trusted from start to end.

HDPE (High-density polyethene) bottles are still widely used to pack medicine because they are strong and safe. These bottles need clear and lasting labels to help track the product. UV laser printers do this well by making dark, clear marks on the light surface of HDPE bottles. These labels are easy to read, stay on long, and follow industry rules.

Minimizes thermal impact

Photolysis treatment inhibits damage

UV lasers give off intense light that can break the bonds between molecules. This helps mark or process materials without creating heat on the surface, reducing damage and providing very accurate results.

Photolysis treatment inhibits damage

It also works well on shiny metals like gold, silver, and copper without creating too much heat. This helps avoid black marks and rough edges, keeps the surface smooth, and allows precise, accurate markings that resist rust.

Photolysis treatment inhibits damage

As electronics get smaller, the plastic covering them becomes thinner. A regular laser (1064nm) might go through this thin plastic and damage the parts inside. A UV laser (355nm) is a better choice because the surface absorbs it and doesn’t go deep, protecting the inside from damage.

Product Applications

CO₂ lasers use carbon dioxide gas to create clear and consistent marks on many materials, such as cardboard, glass, coated metals, paper, plastics, and acrylic. These lasers are known for being accurate and adaptable. They make permanent, high-contrast marks without touching the material, keeping delicate surfaces safe and undamaged.

CO₂ lasers work quickly, helping increase productivity in busy factories. They need little maintenance and last a long time. They are also eco-friendly because they don’t use inks or chemicals and create little waste. With adjustable settings and easy installation, they can be customized for different materials and production lines, making them a valuable and cost-effective tool for manufacturers.

list of items

Each CO₂ laser printer comes with everything needed for easy setup and use. It includes the laser unit for clear, permanent markings, an electric control box to manage the system, and a precise encoder to ensure accurate marking based on the production line’s speed. A sensor is also included to detect products and automatically trigger the laser when needed.

The system has a simple touchscreen for easy use, letting you change settings, track performance, and manage marking tasks. A strong lifting bracket helps mount the printer easily, adjusting to your production line’s height and layout. It also comes with all the wiring you need and complete manuals for setup and fixing problems.
