Yantai Dongruitai Welding and Cutting Equipment Co., Ltd. is one of the leading manufacturers and suppliers of metal fiber laser marker in China. We are committed to providing high quality customized machines with low price. Welcome to wholesale the newest metal fiber laser marker made in China here from our factory. 1 years warranty is available.

Permanent, high-contrast traceability marking can be achieved without the need for consumable inks or regular replacement of worn tools, which is crucial for high-speed production. Our compact metal fiber laser marker features a pulsed 1064nm fiber laser engine paired with high-speed digital galvanometer scanners. This system is designed for Direct Part Marking (DPM), serial numbers, QR codes, and fine logos, enabling clear micro-details as small as 1mm letters while maintaining stable operation in factory environments.

Engineering Advantages

High Beam Quality (M² < 2) & Fine Edge Resolution

Challenge: Fine component identification requires microscopic precision without burrs or thermal distortion on delicate electronic metal pins, surgical tools, or bearing surfaces.
Our Solution: Operating with an optical beam quality factor of M² < 2 and a 1064nm pulsed wavelength, the laser spot remains tightly focused.
Production Effect: This fiber marking laser machine can achieve a minimum character height of 1×1 mm for English letters (2×2 mm for Chinese characters), with a repeat accuracy of 0.0123 mm. It is capable of engraving clear and distortion-free marks, making it suitable for high-density barcodes and fine anti-counterfeiting microtext.

High-Speed Galvanometer Scanning (7000 mm/s)

The Application Challenge: Marking cycle time directly impacts the overall production line throughput.
Our Solution: Utilize a high-performance digital galvanometers driver optics deliver marking speeds up to 7000 mm/s.
Production Effect: Fast beam repositioning dramatically trims single-part dwell times, enabling seamless inline processing or high-volume batch loading without causing floor bottlenecks.

Air-Cooled Structure

Challenge: Traditional water-cooled lasers require coolant refills, filter replacements, are larger in size, occupy more space, and result in more complex equipment layouts.
Our Solution: The integrated air-cooling system efficiently dissipates heat generated by the 1064nm pulsed solid-state laser core. Total system power consumption remains under 500W.
Function: Disabling external chillers can reduce energy costs, eliminate the risk of refrigerant leaks, and significantly lower maintenance costs during continuous production.

Frequently Asked Questions

Q1: What is the main operational difference between 20W, 30W, 50W, and 70W fiber lasers?

A: All power options achieve identical high accuracy (0.0123 mm). Higher wattage options (50W/70W) deliver deeper metal penetration per pulse and faster cycle speeds on hard alloys like carbon steel, whereas 20W/30W models excel at surface discoloration, light etching, and barcode marking on thin metals.

Q2: What vector and graphic software formats does the control system support?

A: The laser system runs on Windows (Win 7/8/10) and supports industry-standard marking software (EZCAD). It imports DXF, PLT, AI, DST, BMP, JPG, and automatically generates sequential serial numbers, dates, batch numbers, and 1D/2D barcodes.

Q3: How long do the laser sources last, and what routine maintenance is needed?

A: The solid-state fiber laser engine offers an operational lifespan up to 100,000 hours. Because the system uses internal air cooling and contains no wear-and-tear lamps or mirrors, no routine consumable replacements are required-simply keep the F-theta lens clean with optical wipes.
