HeatSign Fiber Laser Marking Machines
Fiber lasers are one of a group of solid-state lasers and are the most modern and popular laser marking technologies in the market today. They are low-maintenance and use an efficient solid-state laser source.
Fiber laser marking machines also offer unprecedented versatility, as a wide range of materials can be marked using this technology. With that kind of versatility, this kind of technology is applicable for both light commercial and heavy industrial activities.
Our HeatSign fiber laser marking machines use an IR cooling system to remain in top shape during operations and feature absolutely zero consumables. These laser marking machines are also environmentally friendly and extremely reliable. They can be used on metals, ceramics, and various plastics.
Currently, our most popular offering machine is the HS-FL20 Fiber Laser Marking Machine. This line of laser marking machines includes an environmentally friendly 20-watt laser engraver system. The cooling system is highly efficient, while the engraving marking is permanent and of high quality.
HeatSign also can customize machine features that make the marking of your goods much easier, such as auto weigh feature:
- Auto-weighing feature allowing you to get accurate weight measurements of your product and auto mark data on that. You could check the video link as follows.s
• The ability to record, ma,rk and classify goods for precision production. This works particularly well with jewelry. For example, you want to weigh and mark some gold rings. You can have them classified such that rings weighing from 0 to 5kg fall under classification A, rings weighing from 5.5 to 10kg will be classified B, and so on, then auto laser mark on that.

How HeatSign’s Auto-Weighing Feature Supercharges Your Production Line
HeatSign’s fiber laser marking machines now come with an auto-weighing function—and it’s a real game-changer for automated production. Instead of weighing and marking products in two separate steps, this smart system does both in one seamless flow.
Here’s How It Works
Products roll in on a conveyor → get weighed on the spot → the weight data is instantly sent to the laser → the machine marks it right onto the product.
No stops. No delays. No extra hands needed.
Why It Matters
-
Less manual work – Your team can focus on higher-value tasks
-
More accuracy – Real-time data = no human error
-
Faster production – Weigh + mark in one smooth motion
-
Better traceability – Every item leaves your line ready for the supply chain
Can Your Marking System Handle All Your Products?
Auto-weighing laser marking systems are designed to handle a wide range of product types and materials, making them highly versatile for various industries. These systems can mark metals, plastics, glass, ceramics, textiles, and even food packaging materials with precision. By adjusting the laser’s power settings and using specialized software, manufacturers can customize markings to meet specific requirements without compromising the integrity of the material.
For example:
-
Metals: Laser marking can engrave serial numbers or weight data onto automotive components like engine parts or aerospace parts, ensuring durability under extreme conditions.
-
Plastics: Fiber lasers can mark high-contrast identifiers on materials like polypropylene or nylon without causing deformation. This is particularly useful in industries such as electronics or medical devices.
-
Food Packaging: Laser systems can mark expiration dates, batch codes, and QR codes directly onto flexible packaging films or aluminum cans. This ensures compliance with food safety regulations while maintaining product integrity.y
Where Can You Use Auto-Weighing Laser Marking? Pretty Much Everywhere.
HeatSign’s auto-weighing laser marking systems aren’t just powerful—they’re built to flex across industries. Whether you’re in automotive, food, or healthcare, this solution keeps you compliant, traceable, and efficient.

FAQs
What is the key advantage of an 'auto-weighing' laser marking system for a production line?
The key advantage is that it combines two steps into one seamless flow. The system automatically weighs the product and then instantly sends that data to the laser, which marks it directly onto the item. The guide notes that this process requires no stops, no delays, and no extra hands.
For marking on food packaging like flexible films, how is this system a better choice than an ink-based one?
For food packaging, this system is a better choice because it is a clean, permanent, and eco-friendly process. The guide emphasizes that it uses no ink or chemicals, so there is no mess and no risk of contamination, ensuring it is compliant with food safety labeling rules.
What are the main integration options available for connecting this system to a factory's network?
The system is designed for modern factory integration. The technical specifications list several connectivity options, including Ethernet/IP, PROFINET, and PROFIBUS, and it is also noted for its compatibility with existing ERP and MES systems.
The guide states that the system has an 'autofocus' feature. Why is this useful for a production line?
The autofocus feature is useful because it allows the machine to automatically adjust for products of varying heights. This is a key feature for a dynamic production line, as it ensures the laser remains perfectly focused for a clear mark without needing manual adjustments for each different item.
