Your production line runs fast. You cannot afford a marking system that slows it down. When you need to add permanent, complex QR codes, batch numbers, or anti-counterfeit logos to thousands of caps per hour, standard methods simply fail.
HeatSign’s “Marking on the Fly” Laser Systems sync directly with your conveyor belt. We deliver instant, high-contrast, and melt-free traceability on moving caps—without ever stopping your production line.
If you are running a high-speed, high-volume bottling line, every second of downtime costs you money. When it comes to adding complex QR codes or batch numbers, standard marking methods are simply holding your production floor hostage:
Zero Ink, Zero Clogging. Continuous Inkjet (CIJ) printers bleed money on expensive solvents and constantly halt production lines with clogged nozzles. HeatSign utilizes 30W Flying Fiber and 10W UV Lasers to engrave permanent, smudge-proof codes directly into the material, delivering 100,000+ hours of maintenance-free operation with zero daily consumable costs.
Marks “On the Fly” Without Stopping. Standard desktop lasers require products to physically pause under the lens, instantly bottlenecking high-speed bottling lines. HeatSign utilizes advanced rotary encoders and photoelectric sensors to auto-sync our lasers with your conveyor, effortlessly tracking and engraving complex QR codes in just 91 milliseconds while caps move at full speed.
Marks Thin Plastics Without Melting. Standard thermal lasers will instantly burn, warp, or yellow delicate PE and PET motor oil caps. HeatSign utilizes a premium 10W UV Laser to perform a “cold” photochemical reaction, instantly generating ultra-high-contrast marks on sensitive plastics with absolutely zero thermal damage.
When it comes to high-volume bottling and packaging, one laser does not fit all. Whether you are running sensitive plastic beverage caps or tough metal oil closures, you need a system that syncs perfectly with your conveyor. Meet our top-performing “marking on the fly” lasers built specifically for the packaging industry:
Both of our “Marking on the Fly” systems come standard with advanced rotary encoders and photoelectric sensors, meaning both will easily sync with your fastest conveyor belts. Your decision does not depend on speed—it depends entirely on the material of your closures. Using the wrong laser wavelength can lead to melted plastics or faint, unreadable codes. Use this quick selection matrix to find your perfect match:

👉 Rule #1: If your cap can melt, go UV. If you are marking high-volume plastic motor oil caps or thin beverage closures, the 10W UV Laser is your only safe choice to guarantee a flawless QR code without destroying your inventory.
👉 Rule #2: If it’s metal, go Fiber. If your production line handles aluminum caps, metal crowns, or exceptionally hard opaque plastics, the 60W Fiber Laser delivers the brute-force speed and zero-maintenance reliability you need.
Cap materials and conveyor line speeds vary wildly. Don’t risk bottlenecking your high-volume production or melting your inventory on guesswork. Let our technical engineers evaluate your specific closure material, required line speed (m/min), and daily throughput. We will recommend the exact “marking on the fly” technology you need.

Not at all. Our flying laser systems are specifically designed for continuous “marking on the fly.” Equipped with high-speed Galvo scanners (up to 12,000 mm/s) and auto-syncing rotary encoders, they engrave QR codes and batch numbers in milliseconds while the cap is moving, easily keeping up with conveyor speeds of up to 350m/min.
If you use a standard thermal laser, yes. However, this is exactly why we recommend our 10W UV Laser System for thin plastics. It utilizes a “cold” photochemical reaction rather than intense heat, guaranteeing a high-contrast, permanent mark with absolutely zero thermal damage, warping, or yellowing.
Every HeatSign flying laser comes standard with an industrial rotary encoder and a photoelectric sensor. The sensor detects the approaching cap, and the encoder constantly feeds the exact real-time speed of your conveyor belt to the laser’s software. If your line speeds up or slows down, the laser automatically adjusts, ensuring the mark is never stretched or distorted.
Absolutely zero. This is the biggest financial advantage of switching to a flying laser. There are no ink cartridges to buy, no makeup solvents to replace, and no nozzles to unclog. Your daily consumable cost drops to $0, and the solid-state laser source is built to last up to 100,000 hours.
