While standard 20W or 30W fiber lasers are sufficient for basic surface marking, they struggle with deep engraving tasks, requiring multiple slow passes that generate excessive heat. The 50W Fiber Laser Marking Machine For Deep Metal Engraving solves this production bottleneck. Powered by a robust 50W fiber laser source, this machine delivers a massive spike in peak power. It is specifically engineered to vaporize metal rapidly, making it the industry standard for deep 3D engraving on steel molds, serializing firearms, and even cutting thin precious metals (like 0.5mm gold and silver) for custom jewelry. For B2B fabrication shops, upgrading to a 50W system drastically reduces cycle times per part, significantly increasing your daily production output and overall profitability.

High-Power Deep Engraving

The 50W laser source provides the necessary energy density to carve deep trenches into hard metals (stainless steel, brass, titanium, and tool steel) quickly, producing crisp, high-contrast 3D reliefs and permanent serial numbers.

Thin Metal Cutting Capability

By utilizing high-speed, multi-pass hatching strategies in the software, the 50W machine can cleanly cut through thin sheets of gold, silver, and brass (up to 0.5mm - 0.8mm), making it a highly versatile tool for custom jewelry fabrication.

Genuine EZCAD Software

The machine is driven by the industry-standard EZCAD control board. The software is highly intuitive, supports automated serialization (barcodes, QR codes, sequential numbers), and imports vector files directly from AutoCAD or Adobe Illustrator.

 High-Speed Galvanometer Scanner

Equipped with an industrial-grade Sino-Galvo scanning head. It operates at a carving speed of up to 7,000 mm/s with a repeating precision of ±0.002mm, ensuring absolute consistency during high-volume batch production.

Zero Maintenance (Air-Cooled)

The solid-state fiber laser requires no water chillers, no flashlamp replacements, and no consumable inks or gases. The built-in air-cooling system ensures stable 24/7 operation with an expected laser source lifespan of over 100,000 hours.

"Many clients ask if they really need 50W instead of 30W. If you are only marking black text on aluminum, 30W is fine. However, if your business involves engraving deep logos into hard P20 mold steel, or cutting out custom name-necklaces from 0.5mm silver sheets, 50W is mandatory. A 30W laser will take 20 passes to achieve a certain depth, building up residual heat that can warp thin metal parts. The 50W laser achieves the same depth in just 5 passes. It vaporizes the material so quickly that the surrounding metal stays cool. For jewelry workshops and industrial mold makers, this 60% reduction in processing time means the machine pays for itself within the first few months of operation."

Metal Components & Fasteners: Ideal for tracing codes, serial numbers, and logos on gears, brackets, and hydraulic fittings.

Souvenir & Gift Industry: Custom engraving on items like dog tags, flasks, wallets, and slate coasters.

Firearms Industry: Permanent marking of serial numbers and ID information for legal traceability.

Jewelry & Accessories: Delivers subtle and permanent decorative engravings on high-end metal pieces.

Tools & Dies: Crisp micro-etching on precision cutting tools and industrial dies.

Q: Can this 50W machine mark on plastics?
A: It depends on the plastic. A 1064nm fiber laser works excellently on hard, opaque plastics like ABS, PVC, and PC (often used in electrical switches and automotive buttons). However, it will pass straight through transparent plastics or acrylics without marking them. For clear acrylic or wood, you need a CO2 laser.

Q: Do I need to buy a separate rotary attachment for cylindrical parts?
A: The machine comes pre-wired with an aviation plug for a rotary axis. If you need to engrave rings, tumblers, or mechanical shafts, you can purchase our optional rotary chuck. The EZCAD software has a built-in rotary marking module that makes setup very simple.

Q: How deep can the 50W laser engrave into stainless steel?
A: With optimized parameters and multiple passes, the 50W laser can easily engrave 0.5mm to 1.0mm deep into stainless steel or brass. This is ideal for creating mold cavities, custom coins, or deep firearm engravings that must comply with ATF depth regulations.

Q: What is the warranty and technical support policy?
A: We provide a standard 2-year factory warranty for the entire machine. We also offer lifetime remote technical support. Our English-speaking engineers can assist your operators via video call or TeamViewer to help set up specific engraving parameters.

Q: How is the machine shipped for international orders?
A: The machine is securely packed in a vacuum-sealed, export-grade wooden crate to prevent moisture and shock damage. We can arrange shipping via sea freight (LCL) or fast air courier (DHL/FedEx) directly to your workshop door.
