Mold laser welding machining principle


The principle of laser processing: the laser emitted by the laser generator passes through a series of processing, and the energy is highly concentrated in a small range after the lens focus. If the processed material absorbs the laser well, the material in the irradiated area will quickly heat up because of absorbing the energy absorption of the laser. Depending on the properties of the material (such as melting point, boiling point, the temperature causing chemical changes), the workpiece will undergo a series of physical or chemical changes, such as melting, gasification, generation of oxides, discoloration, and so on. This is the principle of laser processing.



Advanced processing mode, high efficiency


Compared with the traditional machining, the focused laser is like a very fine invisible tool, which "burns" the surface of the local area of the object point by point. It is characterized by no contact with the workpiece, no mechanical extrusion or mechanical stress, so it does not change the physical properties of the processed articles; because the size of the laser focusing is small, the thermal influence area is small, and the processing is fine, some conventional processes can be completed.



In-kind Shooting




Applied range


Large precision injection molding, die casting mold repair, beryllium copper mold, aluminum casting, sand hole, copper casting, air hole repair. Welding and supplementary welding processing of large-piece products.



Performance characteristics

Attachment and consumables


Open hair mold laser welding machine protection lens 
Description of accessories: During the use of the mold laser welding machine, there will often be the phenomenon of iron splashing on the laser lens when melting. The lens plays a role in protecting the internal focusing lens. If there is too much iron adhesion to the protective lens affecting the laser power, the lens needs to be replaced.
  Mold laser welding machine welding wire pen
Parts description: this laser wire pen with a lock, can lock the 0.3-0.6 welding wire, especially for the case of deep hole and deep groove is not easy to hold the welding wire welding, welding wire pen plays a role in stable wire, is an indispensable tool for mold laser repair.

Mold laser welder foot switch
Description of accessories: in the use of laser welding machine, according to different situations, will continuously step, put the laser control foot, long time use will cause the aging or failure of the foot switch, found failure, consider replacing the foot switch.
  Inlet die laser welding wire
Consumable description: This series of laser welding wire, imported from Germany, packaged by sealed plastic cylinder, mainly for the laser repair welding of mold with high requirements, can meet the laser welding of mirror mold, nitride mold, high hardness mold and other molds.

Laser welding wire of the open mold
Consumable description: This series of laser welding wire, made of imported mold welding wire for fine processing, divided into different materials, can meet the laser repair welding quality of most molds, cost-effective.
  Mold laser welder light bulb
Consumable description: lighting bulbs in use for a period of time, due to the life of the bulb, will appear aging or damage, need to be replaced in time.
