Pulse laser cleaning machine and continuous laser cleaning machine

Pulse laser cleaning machine and continuous laser cleaning machine are two common laser cleaning equipment, which have some differences in principle, application scope, cleaning effect, equipment cost, and operation. Below, we will analyze these differences and compare the two cleaning methods in detail.

Difference 1: Differences in principle

Pulse laser cleaning machine: The pulse laser cleaning machine uses high-energy and high-frequency pulse laser beams to instantly heat and cool the surface of objects, forming an instantaneous temperature gradient and thermal stress, causing pollutants and thin coatings to detach from the surface. The principle is to generate high temperature and pressure instantly through the brief and high-energy irradiation of laser pulses, which quickly evaporate or crush pollutants, achieving a cleaning effect.

Continuous laser cleaning: Continuous laser cleaning is the process of continuously emitting a laser beam to heat the surface of an object, achieving a cleaning effect. The characteristic of continuous laser is the continuous and stable output of energy, which often has a mild cleaning effect on the surface of objects.

Difference 2: Differences in application scope

Pulse laser cleaning machine: Pulse 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 pollutants, such as paint, oxides, welding slag, etc. Due to the characteristics of high energy and short action time, pulse laser cleaning is suitable for cleaning objects with high surface requirements.

Continuous laser cleaning: Continuous laser cleaning has certain applications in medical device disinfection, paper cleaning, and other fields. Compared to pulsed laser, continuous laser has lower energy and is more suitable for cleaning objects that require continuous heating.
