Laser Rust Removal & Sandblasting Machine Rust Removal, Which One is Better?

May 09, 2022

Laser rust removal mainly uses a laser beam to work on the workpiece with rust stains. High-frequency high-energy laser pulses irradiate the surface of the workpiece, and the coating layer can instantly absorb the focused laser energy, so that the oil stains, rust spots or coatings on the surface can be instantly Evaporation or peeling, a cleaning method that effectively removes surface attachments or surface coatings at high speed, and laser pulses with very short action time will not damage the metal substrate under appropriate parameters.


The rust removal of the sandblasting machine mainly uses compressed air as the power to form a high-speed jet beam and then spray it to the surface of the workpiece to be treated at a high speed, so that the surface of the workpiece can be changed.


Both laser derusting and sandblasting are mainly used for the treatment of various pollutants such as rust stains on some workpieces, but the efficiency and mode of action of the two are different. Laser derusting can be carried out directly during processing, while sandblasting It is necessary to remove the excess material on the surface of the workpiece to achieve a better rust removal effect. In contrast, the processing efficiency of laser rust removal is higher than that of sandblasting machine; secondly, the operation steps of sandblasting machine are a bit cumbersome, not to mention low efficiency, sometimes it may damage the workpiece, not clean, and cause environmental pollution, etc. and other phenomena, and laser rust removal is a green, non-destructive cleaning and low-cost cleaning processing method.


Laser rust removal does not require any chemicals, and the waste after rust removal is solid and harmless powder, which can completely solve the environmental pollution problem caused by chemical rust removal; and laser rust removal is a non-contact processing method, let alone worry about it. Damage or deformation to the workpiece, and the initial investment of the laser rust removal system is high, but it can be used stably for a long time, with a service life of up to 10 years, low operating cost, high speed, high efficiency, time saving, and can be quickly obtained. The return on investment, in the long run, is lower cost than the blast machine method.


In contrast, the overall advantages of laser rust removal are higher than those of sandblasting machines, and the efficiency is also better!
