How To Choose The Right Handheld Laser Cleaning Machine?


As we all know, metals are prone to rust. Many industrial fields are closely related to metals, such as molds, rail transit, aerospace, etc. Once rust occurs, it will affect performance and service life. Do you know how to choose a suitable laser cleaning machine for rust removal? This article briefly discusses the selection of handheld laser cleaning machines.

How To Choose The Right Handheld Laser Cleaning Machine?

Here are some considerations when choosing a handheld laser cleaning machine.

1. Consider the Cleaning Requirements

Rust removal, paint removal, and oxidation layer removal on metal surfaces are the most widely used for laser cleaning. There are differences in essential parameters such as wavelength and power of different lasers. Different materials and stains have different requirements for laser wavelength, power, etc. In actual cleaning work, different laser cleaning methods need to be selected according to actual conditions.


New Energy/Power Battery

Lithium Battery Pole Piece Cleaning, Cover Cleaning, Blue Film Cleaning

Aerospace Engineering

Cleaning of Engine Parts Before and After Welding; Cleaning of Launch Vehicle Storage Boxes Before and After Welding; Removal of Paint and Release Agents from Composite Materials; Mold Cleaning

Mold Products

Removing carbon deposits from tire molds, packaging molds, injection molds, sealing ring molds, food molds, etc.

3c Industry

Paint removal from selected areas of circuit boards and cleaning of PVD coating fixtures

Car Manufacturer

Body cleaning before welding, wheel hub cleaning, body paint removal, silent tire cleaning

Ocean Ship

Pre- and post-welding cleaning, parts paint removal, oil removal cleaning

Bridge and Highway Maintenance

Paint and rust removal of bridge structural parts; paint removal of highway guardrails


Aluminum alloy body cleaning before and after welding; automatic wheel set cleaning, bogie cleaning, motor cleaning, etc.

Offshore oil production platform coating removal; pipeline paint removal, rust removal, etc.

Food Industry

Cleaning of soy sauce fermentation tanks, metal baking pans, molds, etc.

Thermos Cup

Removing paint from the bottom and walls of the thermos cup

Other Industry

Cleaning of metal oil filters and filter tubes; stainless steel polishing; laser rust and oxide removal

Different cleaning requirements require different types of cleaning equipment. Common laser cleaning machines include continuous and pulse laser cleaning machines.

  • Pulse laser cleaning machine

Simply put, the pulse laser cleaning machine will not cause damage to the original parts and is suitable for products with high cleaning requirements. The parameter adjustment dimension is higher, and the range is wider. It can meet the surface cleaning of various materials.

  • Continuous laser cleaning machine

In actual laser cleaning applications, continuous laser cleaning machines are rarely used. There are also a few applications, such as large steel structures, pipelines, etc. Due to their large size, fast heat dissipation, and low requirements on substrate damage, continuous fiber lasers can be selected.

2. Power Selection

Power is one of the key parameters of a laser cleaning machine and directly impacts the cleaning effect. The higher the power of the laser cleaning machine, the faster the cleaning speed. Of course, the parameter setting issues during actual cleaning also need to be considered.

The common laser cleaning machines on the market are divided into pulse and continuous types. Pulse type is 100W, 200W, and 300W; while continuous type is 1000W, 1500W, 2000W, and 3000W.
For example, the 3000W laser cleaning machine is suitable for cleaning thick rust layers, paint layers, deep oil stains, surface roughening, weld cleaning, and other processes. The 3000W laser cleaning machine has greater power, faster cleaning speed, and higher efficiency.

3. Stability of Equipment Operation

When we choose a laser cleaning machine, the stability of equipment operation is a significant reference factor. Stability directly affects the quality and efficiency of cleaning. If the equipment operates unstable, it may cause damage to the original parts.

4. Convenience of Operation

The convenience of operation and subsequent equipment maintenance are needed to be considered. There are many benefits to using a handheld laser cleaning machine. They are more compact and portable than traditional cleaning machines. This makes them easier to operate in tight spaces. They also use less electricity and produce less noise, making them more environmentally friendly.

Recommended Handheld Laser Cleaning Machines

To meet the rust removal needs, ZLTECH Laser has launched handheld laser cleaning machines for metal cleaning.

1. Benefits create profits. The handheld laser cleaning machine is simple to operate, quick to use, and has no user threshold. Compared with traditional grinding, chemical reagent cleaning, and other methods, it greatly reduces labor intensity.

2. “Ready to use and operate when powered on.” This means that it has no consumables and reduces production and labor costs.

3. Synchronous cleaning and synchronized processing can be realized without polluting the environment, shortening the time spent on workpiece cleaning. Improving efficiency means increasing income, allowing users to achieve the purpose of “invest once and get rid of it forever.”
