Hebei Juliang Technology Co., Ltd. is one of the leading manufacturers and suppliers of air cooled handheld laser rust cleaner in China. Please feel free to buy CE approved machinery made in China here from our factory. All customized machines are with high quality and competitive price.
Think of a handheld fiber laser rust remover as a super-precise tool. It uses a laser beam to zap rust, paint, and oxides off metal, but it doesn't damage the underlying material. There are no harsh chemicals, no rough abrasives, and no extra mess to deal with afterwards. Just aim the laser at the spot, pull the trigger, and the gunk turns into dust you can easily vacuum up.
This is a real game-changer for everyday workshop tasks. It's perfect for getting surfaces ready for welding, restoring old equipment, cleaning molds, or any job where you'd typically grab an angle grinder or sandblaster. Plus, it's air-cooled, so no need for water chillers, coolant hoses, or worrying about freezing in winter. Just plug it into a standard single-phase outlet and you're good to go.
We've spent enough time in real workshops to know that a machine is only as good as what it's made of. Here's the logic behind our material choices-because "it's built tough" doesn't cut it when you're explaining this to a fabricator who's seen machines fall apart after six months.
To ensure long-term stability and precise optical alignment, our welded steel chassis receives a stress relief treatment. Welding can introduce internal stresses that gradually cause distortion, particularly with movement on uneven surfaces or exposure to varying temperatures. This essential step prevents these issues, keeping your machine aligned and reliable for years to come.
Injection-molded components form the control unit's housing, offering genuine shock absorption and dust protection. These aren't just thin plastic covers; they're engineered to effectively block grinding dust and metal particles from the sensitive electronics, which is often why other 'compact' units break down too soon.
Weighing less than 1.2kg, the cleaning head is light enough for operators to use throughout a full shift without fatigue becoming a safety concern. Its armored delivery cable is built to withstand the rough conditions of working around heavy equipment, unlike the delicate fiber found in lab setups.
This unit is air-cooled by design. Unlike water-cooled systems, which need upkeep like coolant changes and risk freezing in unheated spaces, air cooling sidesteps those issues. We've confirmed its thermal performance can handle ambient temperatures as high as 40°C, meaning the laser source will perform reliably even in hot, tight environments.
This method cleans without damaging the substrate. Grinding is abrasive and removes material, but laser ablation targets only the contamination. Its short pulse duration prevents heat from reaching the base metal, thus preserving metallurgical properties and avoiding heat-affected zones. This is crucial for preparing critical weld joints or cleaning delicate components.
Adjustable parameters for different materials and coatings. Power, pulse frequency, and scan speed are all adjustable through the interface. You can store up to 50 presets-so when you switch from cleaning mill scale off structural steel to removing paint from aluminum, you're not dialing in from scratch each time
Wide scan width (up to 150mm) covers more area per pass, which directly translates to faster cleaning and less operator time. On carbon steel paint removal, cleaning rates consistently outperform continuous-wave lasers at comparable power because pulsed operation concentrates energy more efficiently
Plug-and-play setup. Connect to standard AC220V power, attach the cleaning head, and you're running. No specialized utilities, no facility modifications-just open the crate and get to work

A structural steel fabricator in Southeast Asia was spending too much time on surface prep.
Their workflow: receive hot-rolled steel sections, grind off mill scale and surface rust with angle grinders, weld assemblies, then grind weld seams clean before painting. Each team of two operators spent about 45 minutes per large beam just on grinding. Labor cost, consumable cost, noise, dust, and safety hazards.
They bought a 200W air-cooled handheld pulsed laser cleaner from us. Here's what changed:
Prep time dropped to 12-15 minutes per beam-one operator instead of two.
Surface finish became more consistent-no gouging from over-grinding, no missed patches.
Weld quality improved measurably because oxide layers were fully removed before welding, reducing porosity and rework -9.
Grinding consumable consumption dropped by over 70%.
The unexpected benefit: they now clean parts immediately before welding, rather than days in advance, eliminating the re-rust issue they had with pre-ground material sitting in a humid shop.
Raw Material Incoming: Steel plate, profiles, electronic components, optical modules-all from qualified suppliers with traceability.
Frame Fabrication: The chassis and support structures are welded in-house using jigs to maintain alignment during welding. Tolerance control is tighter than you'd expect for a handheld system because optical alignment depends on a stable frame.
Stress Relief: Welded frames go through thermal stress relief to minimize distortion. This isn't optional-it's what keeps the machine stable over years of use.
Machining: Critical mounting surfaces are precision-machined to ensure the optical path stays aligned. This step is why our machines maintain consistent cleaning performance even after being moved around a shop.
Assembly: Laser source, optical path, control electronics, cooling system, and housing are assembled on dedicated workstations. Each module is tested individually before integration.
System Testing: Full functional test: laser output verification, parameter adjustment range, cleaning performance on standard test coupons, thermal stability check, and safety interlock validation.
Packing: Foam-lined crates with corner protection. Everything is double-checked for shipping security.
Shipment: Documentation, spare consumables, and calibration records are included in the crate.
Q: Can this remove thick epoxy paint or powder coatings?
A: Yes, but thickness matters. For coatings over about 200 microns, you'll need multiple passes or higher power. For very thick coatings (1mm+), mechanical stripping or media blasting is often faster. We can test your sample if you're unsure.
Q: How do I know if 200W or 300W is right for me?
A: Tell us what you're cleaning and how fast you need it done. For weld prep and rust removal on steel, 200W works for most shops. If you're cleaning heavily corroded equipment or running high volumes, 300W pays off in time saved.
Q: Can I see a sample before buying?
A: Yes. We run free sample cleaning tests at our facility on your material. You send us a sample piece, and we'll clean it and show you the results. This is the best way to confirm performance before purchase .
Q: What's the typical delivery time?
A: Standard units usually ship within 15-20 working days after order confirmation. Custom configurations (different cable lengths, specific laser source brands) may take slightly longer. We'll confirm timing when you order.
Q: Is the air-cooled system powerful enough for a hot workshop without air conditioning?
A: Yes, we validated thermal performance up to 40°C ambient. Unlike water-cooled units, this one doesn't need coolant changes or freeze protection. Just keep the intake filter clean-if it clogs, cooling drops off. Monthly filter check avoids that.
Q: Does the 200W model use the same cleaning head and cable as the 300W?
A: Yes, the cleaning head, armored cable, and optics are identical across power levels. You can order a 300W unit later and swap heads if needed. We don't lock you into different accessories per model-keeps spares simple.
Q: Can I customize cable length beyond the standard 5 meters?
A: Yes, we offer 10m and 15m options for working in large fabrications or hard-to-reach areas. Longer cables add some signal loss, so we adjust the calibration at the factory. Just specify your typical reach requirement when ordering.
Q: What's the actual process for returning a unit for repair if needed?
A: You pack the machine, send it to our facility. We test performance, diagnose the fault, quote repair if out of warranty, then fix, burn-in test for 24 hours, and ship back. If still under warranty and not user-damaged, repair is free-you only cover shipping.
Q: How do I verify the machine is performing to spec when it arrives?
A: We include a test coupon of standard carbon steel with known coating thickness. Run our recommended settings on that sample-if it cleans completely in one pass at the specified speed, the laser is within tolerance. If not, we troubleshoot remotely or replace.
Lao Zhang's mechanical processing plant recently received an urgent order, but stubborn oil stains on the parts became a major obstacle. Manual scrubbing was not only inefficient but also frequently delayed delivery deadlines. After hearing from fellow industry peers about the excellent reputation of Hebei Juliang's cleaning machines, he decided to give it a try and contacted the manufacturer.
To his surprise, customer service responded promptly, recommending a suitable model based on his cleaning needs and providing detailed instructions on equipment operation. Upon delivery, Lao Zhang found the installation extremely simple. During the initial test run, the high-pressure water stream precisely cleaned the parts-within just a few minutes, components previously covered in grease and grime were restored to like-new condition, with even the tiniest crevices thoroughly cleaned.
What impressed Lao Zhang even more was the machine's low operating noise and significantly lower water consumption than expected. Now, the plant's cleaning efficiency has increased several times over, and the surface finish of the parts meets all quality standards. Customers have been consistently praising the results during inspections. Lao Zhang now tells everyone he knows that purchasing the Hebei Juliang cleaning machine was truly the right choice-he's found the perfect helper for his business.
