The Wattsan UV TT is an advanced ultraviolet laser marking machine designed to handle even the most challenging materials, including gemstones, highly reflective metals, microchips, and chip substrates. Operating at speeds of up to 7,000 mm/s, this machine is capable of applying images and lettering that can only be seen under a microscope. This article provides an in-depth overview of the key features and functions of this laser marking machine.
Versatile material processing
The Wattsan UV TT stands out due to its ability to handle a wider range of materials compared to fiber and CO2 markers. This versatility is primarily due to its 355-nanometer wavelength, which is ideal for processing most metals as well as non-metallic materials, including:
- Wood
- Glass (borosilicate, armored, optical)
- Plastic
- Stone and ceramics
- Textiles and leather
The laser’s wavelength not only determines the range of materials it can process but also influences the spot size of the laser beam. A smaller spot size results in higher precision, minimal thermal impact, and increased power density. For instance:
- CO2 laser spot diameter: 1 mm
- Fiber laser spot diameter: 0.1 mm
- UV laser spot diameter: 0.0355 mm
This means that, despite its relatively low power, the UV laser is highly efficient. The concentrated power allows for clean, precise markings without overheating or distorting the material. This is especially advantageous when marking or cutting paper, as it avoids carbonization and ensures clean edges.
Precision in specialized applications
While the machine is suitable for various materials, it excels in industries that require extreme precision, such as jewelry manufacturing and microtechnology.
- Jewelry industry: the machine can mark not only precious metals but also precious stones. Its ability to process various types of glass—such as borosilicate, armored, and optical—allows for intricate, controlled markings. The UV laser’s small heat-affected zone ensures precision without damaging delicate surfaces.
- Microengineering: the UV TT is ideal for marking flexible printed circuit board (PCB) materials, ceramic composites, and resin-based substrates. It can create circuits, highlight elements, and even pierce PCBs to produce pockets for microchips. This precision is achieved without damaging the layered structure of the materials.
- Plastic processing: the machine can mark even the most sensitive plastics without compromising their structure. It can handle everything from rigid plastics to soft materials like polybags, ensuring clear and precise markings.
- Metal marking: the machine effectively marks all types of metals, producing bright, durable, and colorful markings on materials like stainless steel, titanium, and copper. The fine-tuning of frequency, ranging from 20 to 150 kHz, allows for the adjustment of color shades when marking metals.
High-speed performance and durable design
Operating at speeds of up to 7,000 mm/s, the machine ensures efficient processing without compromising quality. It can be equipped with either a 3 W or 5 W JPT emitter, depending on the application requirements. It is designed for continuous operation, capable of functioning 24/7, 365 days a year, ensuring high productivity.
Control is facilitated through EZCAD software, which offers extensive settings tailored to various materials and tasks. Additional convenient features include:
- Integrated barcode and QR code generator
- Sequential numbering for tracking purposes
- Customizable lenses for working areas ranging from 75×75 mm to 300×300 mm
- Optional rotary device for marking cylindrical objects
- Adjustable scanning units that can be repositioned or suspended for marking large or irregularly shaped items.
Conclusion
The Wattsan UV TT is an optimal solution for precision marking of fragile, delicate, or complex materials such as copper, microchips, printed circuits, diamonds, rubies, solar cells, medical instruments, certain plastics, and glass. Its key advantages include:
- High-speed operation
- Minimal thermal impact
- Ultra-fine laser beam for detailed markings
- Versatility across various materials
These features make the machine a preferred choice for industries where accuracy, reliability, and material integrity are paramount. Whether for intricate jewelry markings or advanced microtechnology applications, this machine delivers superior results with efficiency and precision.
