Laser processing technology is now valued in major economies around the world, and its application and promotion is fast. Laser manufacturing can be found in various industrial fields. In the mold industry, laser cutting or welding seems to have little effect at present, but the emerging laser cleaning in recent years has huge advantages over traditional surface cleaning.
Since the molds are often in contact with high-temperature raw materials or deal with the tensile stress of stamping, most of the molds are metal molds, and the most commonly used are various alloy steels or mold steels.
In actual use, the mold also has some problems that need to be solved urgently, among which the most important mold residue cleaning problem, so far, there is no good solution. Some metal molds are used for the molding of high-temperature hot melt materials, as well as for the die-casting of some metals. After the product is completed and taken out, there are often raw materials left on the mold, which will directly affect the continuous production of the next product, and even need to stop for manual labor.
The second problem is the rust cleaning of the mold. Most industrial molds are metal steel, and many molds are often rusted when they are temporarily put on hold or in standby after use. Since the mold must be clean before it can be used on the machine, the traditional cleaning will consume a lot of labor, which will bring great cleaning trouble to the manufacturer.
It is worth noting that although laser cleaning can play a good role in mold cleaning, it also faces some challenges. After all, the laser cleaning technology is very new. In addition to cleaning the rust and dirt of the workpiece, is there any erosion on the material of the mold body? Do different materials have different requirements for laser power and pulse? How to control the waste on the surface of laser cleaning without eroding the mold body? These questions are all very important. You must know that it is very important to maintain the accuracy of the mold, which is directly related to the quality of the molded product. Even if 1-2 wires are eroded, the final product specifications are inconsistent with the previous ones.
The principle of laser cleaning is to use the high-energy and high-frequency beam of the laser to hit the surface of the workpiece, so that the surface residues, rust, dirt, oil, etc. can be instantly evaporated or turned into particles and separated from the surface of the workpiece. Anyone who has seen the effect of laser cleaning knows that as long as the laser beam sweeps, the surface will be cleaned in a few seconds.
At present, IFtech laser cleaning has been able to effectively clean planes, curved surfaces, holes and gaps. The common handheld laser cleaning machine is more than enough to deal with the rust of general metal molds, and the cleaning time may be only one tenth of the traditional cleaning. The other is to deal with the residual raw materials on the mold, especially the mold on the production line. The efficiency of manual digging is relatively low. If it is replaced by laser cleaning, the efficiency is much higher.
