Laser cutting process determines the quality of laser cutting

Laser cutting processing refers to the use of the thermal effect generated by the laser beam projected onto the surface of the material to complete the processing process, including laser cutting, laser engraving (laser marking) and so on. Today's automobile consumption exaggerates personalization, and the original mold production is due to its own limitations-the cycle of making molds is very long, and it has been difficult to adapt to faster and faster car replacements. Plastic products produced by laser cutting: save investment in plastic molds: plastic laser cutting does not require molds, no mold consumption, no mold repair, saving mold replacement time, thereby saving processing costs and reducing production costs, especially suitable for large products Or the processing of small batches of plastic products. Using Wuxi laser cutting, moldless rapid processing has huge competitive advantages. Because the laser has four characteristics of high brightness, high directivity, high monochromaticity and high coherence, it brings some excellent characteristics that laser processing plastic products do not have in other common processing methods. The laser output is divided into pulse output and continuous output. The laser used for cutting and welding mainly uses the pulse output method. The pulse frequency mainly affects the cutting speed and the roughness of the incision. To obtain high-speed cutting, high frequency is essential. Strictly speaking, the beam divergence angle is not part of the laser department, but because the laser mode has a great influence on the far-field divergence angle, we will discuss it here. Laser cutting processing to create new plastic product samples: Wuxi laser cutting processing can improve the speed of new product development: after the product drawing is formed, laser processing can be performed immediately, and samples of new plastic products can be obtained in the shortest time. The multi-mode is non-zero index in the XY direction, the beam quality is poor, generally only used for welding rather than cutting. The dual focal length laser cutting head is a fragile item on the laser cutting machine. Long-term use will cause damage to the laser cutting head. Laser cutting is one of the most important indicators to measure the quality of laser. Laser engraving of plastic products: Plastic laser engraving is a laser processing process that uses the high energy density of laser to irradiate the surface of plastic products to vaporize the surface material of the product and produce a clear pattern. The detailed application of laser processing in the plastics industry is as follows: First, laser cutting plastic products: plastic laser cutting is to focus the laser beam on the surface of the plastic material, use the high temperature characteristics of the laser to melt the material, and use the compressed gas coaxial with the laser beam to blow The molten plastic product is moved, and the laser beam and the plastic product are moved relative to each other along a certain trajectory, thereby cutting to form a certain shape. To carry out inspection and maintenance on schedule. The laser with TEM00 mode can obtain the smallest beam diameter, and the smallest slit and faster cutting speed due to its small size in the cutting process.
