Pulsed laser cleaning machine and continuous laser cleaning machine are two common types of laser cleaning equipment. They differ in terms of principles, application scope, cleaning effect, equipment cost, and operation. Below, we will analyze these differences and conduct a detailed comparison of the two cleaning methods.
Difference 1: Differences in principles
Pulsed Laser Cleaning Machine: The pulsed laser cleaning machine uses a high-energy, high-frequency pulsed laser beam to instantly heat and cool the surface of the object, creating a temporary temperature gradient and thermal stress, causing contaminants and thin coatings to fall off the surface. The principle is to achieve cleaning by the brief and high-energy irradiation of the laser pulse, which instantly generates high temperature and high pressure, rapidly evaporating or breaking down the contaminants, thus achieving the cleaning effect.
Continuous Laser Cleaning Machine: Continuous laser cleaning involves continuously emitting laser beams to heat the surface of an object, thereby achieving the cleaning effect. The characteristic of continuous laser is that it outputs energy continuously and stably, and its cleaning effect on the object’s surface is often relatively mild.
Difference 2: Differences in application scope
Pulsed Laser Cleaning Machine: Pulsed laser cleaning machines are widely used in various industries, such as automotive manufacturing, electronic equipment, aerospace, semiconductor processing, etc. It can be used to remove various contaminants, such as paint, oxides, welding slag, etc. Due to the high energy and short action time of pulsed laser cleaning, it is suitable for cleaning objects with high surface requirements.
Continuous Laser Cleaning Machine: Continuous laser cleaning has certain applications in fields such as medical device disinfection and paper cleaning. Compared to pulsed laser, continuous laser energy is lower and is more suitable for cleaning objects that require continuous heating effects.
Difference 3: Comparison of Cleaning Effects
Pulsed Laser Cleaning Machine: The pulsed laser cleaning machine can generate instantaneous high temperature and high pressure, effectively removing contaminants from the surface of objects, and has a good cleaning effect. Due to the minimal impact of the pulsed laser cleaning machine on the substrate, it can clean various surfaces more safely.
Continuous Laser Cleaning Machine: Due to the relatively low temperature of continuous lasers, the cleaning effect is relatively weak and it is unable to handle fragile or easily molten materials. However, continuous laser cleaning usually has some effect on cleaning rough surfaces.
Difference 4: Differences in equipment costs and operational aspects
Pulsed laser cleaning machine: Pulsed laser cleaning machines usually have a relatively high equipment cost because they can achieve zero damage during batch processing and are suitable for cleaning products with strict requirements on the base material surface. At the same time, operators need to have certain professional knowledge and skills to ensure safe operation.
Continuous laser cleaning machine: Compared with pulsed laser cleaning machines, the equipment cost of continuous laser cleaning machines is lower and is suitable for large-scale industrial cleaning requirements.
