Laser processing

Overview

Laser processing technology is a new technology that develops rapidly in the 21st century. Because the optical system can make the laser focus into a very small spot, laser processing can obtain extremely high energy density and extremely high temperature, at which all kinds of hard materials will be melted and vaporized instantly, and then the melt is driven by the steam pressure generated by gasification, and sprayed out at a high speed. Thus, the special processing method of workpiece processing is realized. The comprehensive technology of laser processing includes drilling, grooving, cutting, welding, marking, surface treatment and micro-machining, etc.

Laser drilling

Laser drilling with the help of the laser’s extremely high power density characteristics, so that the processed material is instantly melted and vaporized, and the melted material is pushed out by the huge pressure of the steam, forming a hole. Laser drilling is being widely used in the processing of watches and instruments related to the workpiece, mechanical equipment and parts production.

Laser cutting

Laser cutting uses the laser beam, because it can focus and form a very high power density spot, so the material can be rapidly heated to the temperature of gasification, forming a small hole, and then with the light beam and the relative movement of the material, resulting in small and continuous slit, to achieve the purpose of cutting.
Electronic laser cutting:
SMT module, FPC, pen shell, mobile phone back cover, touch pen tube, electronic cigarette tube, ring, drink straw, valve core tube, valve core, heat pipe, electrode tube, etc.
Medical laser cutting:
sea wave tube, ultrasonic knife, snake bone, catheter, stent, needle, planer knife, developing ring, etc.

Laser welding

Laser welding irradiates the laser beam that meets the power density requirements to the surface of the material that needs to be welded, increases its local temperature to the melting point, makes the binding part of the material melt into a liquid, and then cools and solidifies, so that the two materials are fused together to achieve the purpose of welding. Laser welding is widely used in aerospace industry, shipbuilding and other fields.
