Copper’s extreme reflectivity and high thermal conductivity make it notoriously difficult to mark. HeatSign’s specialized fiber laser engravers—featuring built-in optical isolators and up to 50W of peak power—safely deliver deep, high-contrast, and permanent marks on all copper alloys without damaging the laser source.
Protects Your Equipment. Pure copper reflects laser light like a mirror, which can destroy standard lasers. Every HeatSign machine includes a standard integrated optical isolator that blocks destructive back-reflections, guaranteeing 50,000+ hours of damage-free operation.
Overcomes Rapid Heat Loss. Copper conducts heat so quickly that ordinary lasers fail to leave a mark. Our systems deliver extreme peak power to instantly vaporize the surface, creating crisp, high-contrast black or deep engravings before the heat has time to spread.
Maintenance-Free Production. Eliminate the need for messy inks and toxic chemical etchants. Featuring an efficient air-cooled design, our machines require zero consumables—delivering continuous, eco-friendly reliability whether you are plugged in at a desk or running on battery power.
Because copper requires intense, concentrated energy to overcome its thermal conductivity, we only recommend our highest-performing fiber laser architectures. Choose the form factor that fits your production line.

Choose the HS-FL Desktop Series if: You process small to medium-sized pure copper parts (like PCB foils or micro-connectors) and require maximum clarity or deep engraving. The high-speed Galvo scanner delivers ultimate efficiency and precision for batch processing.
Choose the HS-PFL30M-B Handheld if: Your workpieces are massive, extremely heavy, or already installed (such as heavy electrical busbars or large valves). The true cordless design allows you to “bring the laser to the part,” completely eliminating expensive material handling costs.
💡 Expert Tip: The “Power Rule” for Copper
Because pure copper dissipates heat almost instantly, low-power lasers often fail to leave a clear mark before the heat spreads.
30W is the recommended starting point to achieve high-contrast “Surface Black Marking.”
50W or 60W is the gold standard for “Industrial Deep Engraving.” The extreme peak power instantly vaporizes the copper surface, preventing thermal distortion on the surrounding metal.
Copper alloys can be tricky to mark. Take the guesswork out of your investment—let our engineers recommend the perfect system for your specific part size and depth requirements.
Witness the power of our high-peak fiber lasers. In this real-world demo, see how the machine delivers razor-sharp, high-contrast markings on brass components in seconds—proving its industrial capability on the toughest metals.
Because our machines overcome pure copper’s rapid heat dissipation without warping the material, they are the trusted choice across high-demand industrial sectors.

What Customers Say
This is a real find for those who need to make laser engraving on various materials. This machine is the real engine of our business.
Our company has acquired an engraving machine in order to introduce new technological methods of laser printing into the business. So, let’s about the positive sides of a 20W Fiber Laser Marking Machine. These are primarily the ease of operation and reliability of the machine. The introduction of this equipment in the production process significantly increased the productivity of the workshop, and also expanded the range of products offered to our customers. So do not doubt the efficiency of this equipment, it is worth its money.
Manufacturing small hi-tech parts for the tech industry is a challenge because precision and smart design are the name of the game – not forgetting keeping every millimeter of the part in one piece, of course.

Very effective marking machines available here! The result of Laser marking machine proved to be better than expected!
Yes. While copper’s mirror-like surface can destroy standard lasers, all HeatSign fiber lasers are equipped with a built-in optical isolator. This completely blocks destructive back-reflections, keeping the 50,000-hour laser source 100% safe.
Absolutely. Because copper dissipates heat quickly, standard lasers fail to leave a mark. By using our 35W or 60W machines with optimized parameters (like 95% power and 25kHz frequency), the laser instantly vaporizes the surface to create a permanent, high-contrast black oxidation layer.
No. Our fiber lasers use incredibly short, concentrated pulses. This minimizes the heat-affected zone (HAZ), allowing you to engrave crisp QR codes on copper components as thin as 0.2mm without any physical warping or edge melting.
The 50W HS-FL series is our deep-etching powerhouse. It can easily achieve depths of 0.01mm in a single cycle (and deeper with multiple passes), making it ideal for heavy industrial tracking that must survive harsh environments and abrasion.
No. The handheld unit features a built-in, highly secure Linux touchscreen system. You can design text, QR codes, and serial numbers directly on the screen, or simply import your logos and graphics via a USB flash drive.
The unit is powered by a high-capacity 24V lithium battery that provides 4 to 6 hours of continuous working time. It also features an auto-rest screen design that puts the machine to sleep after 60 seconds of inactivity to conserve power.
