But ever since laser cleaning is introduced in mold cleaning, things have become different. Laser cleaning uses high power and high frequency laser light on the mold surface so that the residue, rust, oi stain, etc. can evaporate from the mold surface or become particle instantly. You might see the result of laser cleaning. When the laser beam moves along on the material surface, the surface can become quite clean within seconds. Nowadays, laser cleaning can be performed effectively on flat surface, curved surface, hole and gap. The common handheld laser cleaning machine is already quite effective on removing rust from general metal molds and the cleaning time is only 1/10 of traditional cleaning. Besides, many manufacturers are now considering installing laser cleaning machines on the mold production lines to realize monitoring and automatic cleaning the material residue on the molds, which is very efficient.

The type and thickness of the materials to be processed: Generally speaking, the thicker the materials, the bigger the cutting difficulty. That means thicker materials require laser cutters of higher power. And there are two common types of laser cutters. One is CO2 laser cutter and the other is fiber laser cutter. For cutting non-metal materials, CO2 laser cutter is often the ideal option. And for metal materials, fiber laser cutter works better. Many people would consider the ratio of investment and output. It is normal that the higher the power of the laser cutter, the more expensive it will be. And different configurations inside the laser cutter also lead to price difference.

After the power of fiber laser cutting machine entered the 10KW era in 2016, the laser processing power gradually formed a pyramid-like layering, with ultra-high power above 10KW at the top, medium and high power 2KW to 10KW in the middle, and below 2KW occupying the bottom cutting application market. The increase in power will bring higher processing efficiency. For the same thickness of metal plates, the processing speed efficiency of a 12KW laser cutting machine is about twice that of 6KW. Ultra-high-power laser cutting equipment mainly cuts metal materials with a thickness of more than 40 mm, and most of these materials appear in high-end equipment or special fields.

Fiber laser has the highest photoelectric conversion efficiency among all the laser sources and it is widely used in laser cutting and laser welding in metal fabrication. However, it is inevitable to generate heat. Excessive heat will lead to poor laser system performance and shorter life. To remove that heat, a reliable laser water cooler is highly recommended. CO2 laser is commonly used in laser cutting, laser engraving and laser marking on non-metal materials. But whether it is DC tube (glass) or RF tube(metal), overheating is likely to happen, causing expensive maintenance and affecting the laser output. Therefore, maintaining consistent temperature is of utmost importance to CO2 laser. See additional details on https://www.teyuchiller.com/.
