Using laser engraving and cutting, the process is as simple as printing on paper using a computer and printer. You can use a variety of graphics processing software, such as CorelDraw, in Win98/Win2000/WinXP environment. Scanned graphics, vectorized graphics and various CAD files can be easily "printed" into the Engraving Machine. The only difference is that printing applies toner to the paper, while laser engraving shoots the laser onto almost all materials such as wood, acrylic, plastic, metal, and stone.

Laser engraving can be divided into dot matrix engraving and vector cutting according to different engraving methods: dot matrix engraving Dot matrix engraving resembles high definition dot matrix printing. The laser head oscillates left and right, each time engraving a line consisting of a series of points, and then the laser head simultaneously moves up and down to engrave a plurality of lines, and finally constitutes a full-page image or text. The scanned graphics, text and vectorized graphics can all be carved using dot matrix. Vector cutting Unlike dot matrix engraving, vector cutting is performed on the outer contour of the graphic. We usually use this mode to perform penetrating cuts on wood, acrylic, paper, etc., as well as marking on a variety of materials.
Baoan District has always been the manufacturing and manufacturing center of Shenzhen LED lighting products. LED lighting materials are also among the seven strategic emerging industries in Shenzhen. Recently, the reporter learned from Baoan Quality Supervision Department that in recent years, Baoan District LED lighting products export return batches and foreign notification recall batches have been increasing year by year. Baoan District has always been the manufacturing and manufacturing center of Shenzhen LED lighting products. LED lighting materials are also among the seven strategic emerging industries in Shenzhen. Recently, the reporter learned from Baoan Quality Supervision Department that in recent years, Baoan District LED lighting products export return batches and foreign notification recall batches have been increasing year by year. According to statistics, 25 batches were returned during the three years from 2015 to 2017, accounting for 60% of the total return batches in the past 10 years. In the same period, the EU notified 13 batches of recalled batches, accounting for 57.7% of the total recalled batches in the past 10 years. According to the investigation and analysis, technical trade measures have become the main cause of return shipments and notification recalls. The reporter learned that technical trade measures represented by traditional requirements such as electrical safety and electromagnetic compatibility have been tightened in recent years. Taking the EU as an example, the recall of LED lighting products in Baoan area has reached 6 batches, involving various types. Products are notified by the European Union that they do not meet the requirements of the Low Voltage Directive. After investigation, the main reason is that after 2016, the new EU low-voltage directive will be implemented. All products manufactured according to the old directive are forbidden to be sold in the EU. In order to meet the latest directive requirements, the company must re-evaluate the product. In addition to the EU countries, developing countries are also paying more and more attention to the application of technical trade measures to protect their products. Taking the BRICS countries as an example, Brazil has included LED lighting products in the national compulsory certification product catalog, while India has comprehensively required products to pass BIS certification. The implementation of these technical trade measures led to a sharp decline in the export volume of Baoan District. In 2016, the export of LED lighting products to Brazil decreased by 49.5% year-on-year, and that of India decreased by 30%. In addition to technical trade measures, Brazil and India have also introduced financial subsidies for their production of LED lighting products, squeezing the market for imported products. With the development of the economy, the requirements for green environmental protection continue to increase. Green and technical trade measures, also known as green barriers, are another important trade measure for developed countries following anti-dumping measures. In particular, the EU and the United States are increasingly demanding energy efficiency indicators based on energy conservation and environmental protection. For example, as of September 1, 2016, the directional LED lamp energy efficiency index EEI can only enter the EU market if it reaches 0.2 or higher, which is 123% higher than the current national standard requirements. The US Energy Star Light Bulb Lamps version 2.0 specification came into effect on January 2, 2017, increasing energy efficiency requirements and increasing the classification of energy efficiency and performance. The implementation of green barriers in developed countries will determine the future development direction and living space of LED lighting products exported by Baoan District. After investigations by relevant regulatory authorities, technical trade measures have become the main incentive for export and return of LED lighting products in Baoan area. To overcome the above difficulties, Baoan Inspection and Quarantine Bureau recommends that the government, enterprises and industry associations work together to strengthen cooperation. The first is to establish a collection, arrangement and tracking system for foreign technology trade measures led by the district government; the second is to promote local standards and laboratory construction to meet the requirements of technical and trade measures; the third is to strengthen corporate environmental management and promote the establishment of ISO14000 environmental protection system. To achieve a breakthrough in green barriers. (
