Laser Cleaning Machines for Residue Removal
Residue removal is a common challenge in many industries, particularly in precision molds, where leftover oil, carbon, and contaminants can affect product quality. Laser cleaning provides a non-contact, highly efficient solution, making it ideal for mould cleaning applications.
Laser cleaning has become an ideal choice for residue or mould cleaning due to its many advantages and advanced technologies.
- Its core advantage lies in non-contact cleaning. This can avoid mechanical stress and medium wear on the mold surface. Laser cleaning is particularly suitable for the cleaning needs of etched and mirror moulds;
- High-precision cleaning can remove micron-level residues, grease, and carbon deposits. This can effectively maintain the geometric accuracy and surface quality of the mould;
- Through flexible fiber optic probes, it can also penetrate microstructures such as ejector holes and exhaust grooves. This can solve the problem of cleaning dead corners.
During the working process, the laser beam irradiates the mould surface, causing the contaminants to heat up and vaporize or peel off instantly. The metal substrate with a high melting point can be well protected.
In terms of technology, the power range of the equipment is adjustable between 100W and 1000W. There are several options for models, including pull rod types and backpack types. It supports adjusting the cleaning line width to meet the needs of different molds. The system features a built-in cleaning database that automatically matches the cleaning parameters for various materials. The laser beam moves with high precision, enhancing the uniformity and efficiency of the cleaning process.
In terms of environmental protection and safety, this technology does not require chemical reagents and does not produce secondary pollution. It can be used with an industrial vacuum system to collect dust generated during the cleaning process. Operators only need to wear protective glasses to work safely. The entire machine operates with minimal noise and is suitable for clean production line environments.
Currently, laser cleaning is widely used in mould cleaning applications, including injection moulding, die casting, rubber vulcanization, and glass processing. It is particularly suitable for precision mould cleaning scenarios that require extremely high standards for surface accuracy and repeatability.

How to Choose a Pulse Laser Cleaning Machine
for Mould Cleaning?
1. Equipment portability
Laser cleaning machines must have good portability in the mold industry. Good portability can adapt to multi-station and complex layout working environments. The lightweight backpack and trolley box design allow the equipment to be easily moved between workshops. They are particularly suitable for cleaning online molds. This reduces the disassembly process and improves work efficiency. Some models are equipped with flexible optical fibers to enter the internal structure of the mold to complete precise cleaning, greatly improving scene adaptability.
2. Cooling system
A stable heat dissipation system is required during the operation of laser equipment to maintain high performance. The air cooling system is suitable for small- to medium-power models. The structure is compact and easy to move, but the cooling capacity is limited. The water cooling system is suitable for medium and high-power models. It is recommended to adopt a dual-temperature dual-control structure to control the temperature zone of the laser and the optical system, respectively. This ensures that the equipment operates at a constant temperature during continuous cleaning, effectively extending its service life.
3. Degree of intelligence
Modern laser cleaning equipment is generally equipped with an intelligent control system. This can greatly reduce the difficulty of operation. Through the built-in process database, the operator can select preset parameters according to the mold material. A quick start and high consistency cleaning effect can be achieved. At the same time, intelligent functions such as graphical interface, real-time monitoring, and fault alarm further enhance the ease of use and equipment safety. Non-professionals can quickly operate them.
4. Beam mode
Spot control is a key factor affecting cleaning quality. Laser equipment usually supports swing mode adjustment. Multiple parameters, such as scanning width, speed, and filling spacing, can also be adjusted. This enables precise control of the beam on the cleaning surface. This function ensures that when processing molds with different textures, it can be thoroughly cleaned without damaging the original surface structure. Therefore, laser cleaning is particularly suitable for high-demand mold surfaces such as etching and polishing.
5. Laser power
Laser power directly determines cleaning efficiency and pollutant treatment capacity. Low-power equipment is suitable for maintenance cleaning with light residues. Medium-power equipment can handle moderate pollution, such as PVD residues and oxide layers. High-power equipment can quickly remove thick carbon deposits and metal sintering layers. The power range is flexible and adjustable. One device is suitable for a variety of working conditions. This greatly improves applicability and return on investment.
6. Economic efficiency
Compared with traditional chemical, dry ice, or sandblasting cleaning methods, laser cleaning has almost zero consumables. Daily expenses only include electricity. No frequent replacement of cleaning agents or abrasives is required. Long-term use costs are extremely low. The equipment is easy to maintain, and the main consumables are protective lenses and filters, with a service life of tens of thousands of hours. Laser cleaning is an ideal solution with obvious cost and environmental advantages in high-frequency cleaning scenarios.

FAQs
Will laser cleaning damage the mold surface, particularly the etched or polished surface? How to ensure accuracy?
Traditional cleaning causes blurred texture or dimensional deviation. Laser cleaning offers precise energy control, and texture protection is superior to mechanical grinding.
Can deep holes/narrow gaps (such as ejector holes and exhaust grooves) be thoroughly cleaned?
Chemical cleaning does not penetrate enough, and dry ice cleaning cannot reach dead corners. Laser cleaning can do it. Through flexible fiber optic probes, it can also penetrate microstructures such as ejector holes and exhaust grooves. This can solve the problem of cleaning dead corners.
How to deal with dust after laser cleaning? Does it pollute the workshop?
The laser cleaning equipment is designed with a reserved fixture. The machine can be equipped with a vacuum cleaner with an activated carbon double filter system.
Can it be cleaned online (without disassembling the mold)? How much impact does it have on the production line?
Equipped with a robotic arm and a slide rail system, online cleaning can be achieved. This can avoid mold disassembly, which is time-consuming and labor-intensive.
Is the laser cleaning machine difficult to operate? Can workers master it quickly?
Traditional cleaning methods are cumbersome and rely on experience. Laser cleaning is different. The laser cleaning machine has preset cleaning parameters and can be started at any time. The operation is simple. Workers only require basic training to begin working.
