Understanding the Core Technology of the YLH-Series Fiber Laser Marking Machine
The foundation of the YLH-Series is its advanced 1064nm wavelength fiber laser source. Unlike traditional CO2 lasers that use gas or YAG lasers that use crystal rods, the fiber laser marking machine utilizes an optical fiber doped with rare-earth elements.
This technological shift offers several critical advantages:
- Beam Quality: The YLH-Series delivers a nearly perfect Gaussian beam, allowing for a minimum line width of 0.01mm.
- Energy Efficiency: These machines operate with ultra-low power consumption (typically under 500W), making the YLH-Series an eco-friendly choice for sustainable factories.
- Longevity: The Raycus fiber source is rated for 100,000 hours, meaning the machine can run for over 10 years in a standard 24/7 production environment without requiring a source replacement.

Comparing the YLH-20L, YLH-30L, and YLH-50L Power Configurations
One size does not fit all in industrial marking. The YLH-Series is strategically divided into three wattage categories to serve different material depths and production speeds.
The YLH-20L Fiber Laser: Precision Surface Marking
The YLH-20L is designed for high-contrast labeling on delicate materials. It is the go-to choice for electronic components where heat management is vital. It creates a crisp, clear mark on the surface of aluminum and rigid plastics without penetrating deep into the substrate.
The YLH-30L Fiber Laser: The Versatile Industry All-Rounder
The YLH-30L is the most popular model for general manufacturing. It offers a faster material removal rate than the 20W version, making it ideal for automotive part marking and hardware tools. It balances speed and price, providing a quick ROI for medium-scale workshops.
The YLH-50L Fiber Laser: Deep Engraving and High-Speed Throughput
For heavy-duty applications, the YLH-50L is the powerhouse of the series. With higher peak power, it can achieve deep metal engraving in hardened steel and brass. It is also capable of cutting thin metal sheets (up to 1mm), effectively acting as a micro-cutting station for jewelry nameplates or shims.
Material Compatibility of the YLH-Series Metal Laser Engraver
The YLH-Series Fiber Laser Marking Machine is optimized for high-reflectivity metals and specific polymers. Its 1064nm wavelength is absorbed efficiently by almost all metallic surfaces.
- Ferrous Metals: Stainless steel, carbon steel, and tool steel. On stainless steel, the YLH-Series can achieve “color marking” by varying the frequency to create controlled oxide layers.
- Non-Ferrous Metals: Aluminum (anodized or raw), copper, brass, and titanium. The YLH-50L is particularly effective at overcoming the high reflectivity of copper.
- Precious Metals: Gold, silver, and platinum. This makes the machine an essential tool for jewelry laser engraving.
- Engineering Plastics: ABS, PVC, and Polycarbonate. The laser triggers a chemical “foaming” or color-change effect in the plastic, resulting in a permanent mark that cannot be rubbed off.
Strategic Applications of the YLH-Series Fiber Laser Marking Machine in the Automotive Industry
In the automotive sector, every component must be traceable for safety and warranty purposes. The YLH-Series Fiber Laser Marking Machine is integrated into assembly lines to provide:
- VIN Plate Marking: High-contrast marking on aluminum or steel plates.
- Engine Component Traceability: Engraving heat-resistant codes on engine blocks, pistons, and valves.
- Backlit Button Marking: “Day and Night” marking where the laser removes the top black paint layer of a car button to reveal the translucent plastic beneath for illumination.
Precision Marking with the YLH-Series Fiber Laser Marking Machine in Electronics and Semiconductors
As consumer electronics shrink, the demand for microscopic marking grows. The YLH-Series features a high-speed Sino-Galvo scanner, enabling marking speeds of up to 12,000 mm/s.
- Microchip Marking: The YLH-20L can engrave legible characters as small as 0.2mm on semiconductor housings.
- PCB Identification: Permanent marking of tracking codes on printed circuit boards that withstand the high heat of soldering ovens.
- Consumer Branding: Logo engraving on mobile phone frames and laptop chassis.
Medical Device Compliance and the YLH-Series Fiber Laser Marking Machine Precision Standards
Medical devices require “UDI” (Unique Device Identification) that is permanent and non-toxic. The YLH-Series Fiber Laser Marking Machine is the preferred choice because:
- Non-Contact Process: The laser does not physically touch the tool, preventing contamination.
- Corrosion Resistance: The marking process on surgical steel can be tuned (annealing) to ensure the mark does not rust during repeated autoclave sterilization cycles.
- Precision: Marking on ultra-thin needles and catheters without compromising structural integrity.
Integrating the YLH-Series Fiber Laser Marking Machine with Industrial Automation and EZCAD Software
The YLH-Series is not just a standalone tool; it is a smart device. It comes equipped with EZCAD 2.12 Professional Software, which supports:
- Variable Data: Automatically generating serial numbers, date codes, and timestamps.
- Vector and Raster Graphics: Importing designs from AutoCAD, CorelDraw, and Photoshop (PLT, DXF, BMP, JPG).
- Rotary Axis Integration: The YLH-Series can be fitted with a rotary chuck for 360-degree marking on cylindrical objects like rings, pipes, or bottles.
- I/O Interfacing: Allowing the machine to be triggered by a foot pedal or an automated PLC (Programmable Logic Controller) on a conveyor belt.
