The common feeding method in EMAR sheet metal factories, laser cutting, can meet customers' fast and precise requirements for cutting materials, while also improving the overall efficiency of Sheet Metal Processing. What is the principle of laser cutting like that? The laser is aimed at a small spot with a Z aperture of less than 0.1mm, allowing for strong power at the focal point exceeding 106w/cm2. At this point, the heat generated by the input of light (converted by solar energy) far exceeds the reflection surface, transmission, or spread of the material. The material quickly heats up to the humidity of the gasification environment and evaporates to produce pores.

Due to the relative linear movement of light and material, the aperture continues to produce a narrow slit with a total width (such as around 0.1mm). The cutting edge has little harm and there is basically no deformation of the workpiece. The laser cutting principle of sheet metal processing in EMAR sheet metal factories also includes assistance with cutting materials that are suitable for the material. When cutting steel, oxygen is used to assist in the exothermic reaction between the vapor and the molten metal material, and to chemically oxidize the material with air. At the same time, it helps to blow away the slag in the cutting seam. Cutting polypropylene and other plastics should be done using air compression, while cutting flammable materials such as cotton and paper should be done using rare gases. The assisting vapor entering the nozzle can also cool the focusing lens, avoiding dust from entering the lens holder and contaminating the lens, which can cause overheating of the lens. Most organic and inorganic compounds can be cut by laser.

Во индустријата за производство на метални материјали, која претставува значителен процент на индустриското производство, многу метални материјали, без оглед на нивната сила, можат да бидат исечени без деформирање (моментно, апликацијата на извонредниот лазерски софтвер може да го исече индустрискиот челик со дебелина близу 20 Природно, за материјалите со висока трансмитација како што се златото, среброто, медерот и профилите на алуминиумската легација, тие се и добри термални водачи, правејќи го исечувањето на ласерот многу тешко или дури и невозможно да се исече (некои тешки да се исечат материјалите може да се исечат со пулсирани бранови ласери бидејќи екстремно силната врвна моќ на пулсот може знач Лазерското сечење нема гребаници, гребаници, висока прецизност и е подобро од сечење на плазма со ниска температура. For many mechanical and electrical engineering processing and manufacturing industries, the intelligent laser cutting system software with microcomputer program flow can easily cut workpieces of different shapes and specifications (workpiece engineering drawings can also be modified), and it is usually preferred over shear compression and compression molding processes; Иако брзината на производството и производството е побавна од брзината на богот на формата, не конзумира форми, не бара одржување на формата и заштедува време за замена на формата, заштедувајќи ги производствените и производствените трошоци и намалувајќи ги производствените трошоци.

On the other hand, from the perspective of how to integrate the mold into the design size and shape transformation of the workpiece, laser cutting can also fully leverage its advantages of precision and good reproducibility. As a preferred manufacturing method for stacked molds, it does not require high-end mold making and laser cutting operation costs are not too expensive, which can significantly reduce the cost of mold products. The additional benefit of laser cutting molds is that the cutting edge of the mold will create a shallow hard bottom layer (heat affected zone), which improves the wear resistance of the mold during operation. The non-contact characteristics of laser cutting give the saw blade the advantage of no stress during cutting and forming, thereby improving its service life.
