Principle and application of laser in knife mold

The principle of laser knife mold processing is to write the product's graphic design drawing (CAD mode) or the actual product after computer programming, and write it into a program approved by the laser knife mold cutting machine and the supporting Steel rule die cutting machine, and print 1: 1 on the proofing equipment Sample proof for technical staff proofreading; then enter the program into the laser knife die cutting machine and Steel rule die cutting machine. The laser knife die cutting machine will laser cut the required geometry on the pattern plate; Steel rule die cutting machine pre-bends the tool; The trained technical workers insert the pre-bending forming tool on the laser-cut stencil. After inspection and proofreading, a pair of laser dies are successfully processed. The characteristic of the laser knife mold is that the computer has replaced the human brain and the laser has replaced the traditional mechanical sawing process, which has made a qualitative leap in the consistency and repeatability of the product.

    Laser has four characteristics of high brightness, high directivity, high monochromaticity and high coherence. The laser beam is focused to achieve a very high energy density. Currently in the industry, laser beams have been successfully used for cutting, drilling, welding and surface modification of materials. Among them, laser cutting is one of the widely used mature processing methods, which accounts for more than 70% of the entire laser processing. Compared with other methods, it has the characteristics of high speed, high precision and high adaptability. Laser cutting also has the advantages of fine slits, uniform gaps, small heat-affected zone, good cutting surface quality, no noise during cutting, and easy control of the cutting process, which is suitable for the processing technology of laser cutters. Based on the many characteristics and advantages of laser, laser external collaborative processing has now formed an emerging sunrise industry, with broad application space and market prospects. At present, in the eastern economically developed regions (especially the Yangtze River Delta, Pearl River Delta and eastern coastal cities) where the packaging industry is developing rapidly, laser molding production has begun to take shape, and it continues to account for 80% of domestic precision molding business. The scale is expanding rapidly. According to statistics from relevant departments, the contradiction between supply and demand is common in laser mold production lines in these regions. (Most manufacturers operate at full load every day and still cannot meet the growing needs of customers. Most manufacturers have plans to expand the scale. ). There are not many professional laser mold production lines in other central and western regions. To be sure, the market potential for developing laser knife molds in these regions is huge.

    At present, some companies use a low-power laser machine to perform laser cutting of computerized scribes on a stencil template, and then use traditional mechanical sawing to perform sipe processing, and manually insert the tool. I believe that the processing procedure is only In an excessive stage, the development direction of die-cutting tools will be laser row die-cutting die.

    With the accelerated pace of post-press cutting and cutting process automation transformation, laser knife molds are inevitable development trend to replace traditional manual knife molds. Of course, laser knife molds and traditional manual knife molds will also go through a coexisting stage. Only through this coexistence At this stage, the laser knife mold can show its technological advancement and strong vitality. As a laser knife mold processing enterprise, it should also use its own services to make great efforts to publicize and promote this new star.
