Magnesium Alloy Etching Plate is based on magnesium alloy material, through the etching process to form a specific pattern, texture, structure or achieve a specific shape change on its surface. Generally AZ31B Hot Rolled Magnesium Alloy Plate, some customers will choose to use High Purity Magnesium Plate.
Magnesium Alloy Etching Plate making process for the sun plate, acid washing, alkali washing and so on several steps, after processing the finished product installed in the hot stamping machine for direct use. Before the use of zinc plate, copper plate, but due to the zinc plate, copper plate in the plate-making process produces a lot of waste liquid, can not be recycled, particularly serious environmental pollution, Europe and the United States gradually use magnesium alloy etching plate instead of zinc plate, copper plate.
Magnesium alloy etching plate has the following applications in the field of printing and packaging:
1. Hot stamping plate
Etched magnesium plate has a small heat capacity ratio, in the process of hot stamping can quickly absorb and emit heat, hot stamping effect is good. Compared with the traditional copper plate, zinc plate, magnesium alloy etching plate plate making time is short, can improve production efficiency, such as manufacturing the same specifications of the plate, magnesium plate is usually as long as 5min, while zinc plate and copper plate preparation time were 25min and 30min. in addition to the same size of the template, magnesium plate is lighter in weight, transport, installation, sticking plate are convenient and quick, in the production of large-scale printing and packaging can reduce the artificial Handling costs and labour intensity. Magnesium alloy etching plate is 20% higher than copper plate, which can effectively improve processing speed and save labour costs.
Application cases: In the high-grade gift packaging, tobacco and wine packaging, cosmetic packaging and other high requirements for hot stamping effect in the field has been widely used, such as Moutai, Wuliangye and other well-known brands of some of the packaging products used magnesium alloy etching plate made of hot stamping plate, hot stamping text and patterns are more beautiful, bright.
2. Embossing plate
Advantage: High-precision patterns and texts can be made on magnesium alloy plate through etching process, and the patterns and texts can be accurately highlighted during the embossing process, which gives the packaging surface a strong three-dimensional sense and texture, and enhances the grade and aesthetics of the packaging. Magnesium alloy has good flexibility and elasticity, it is not easy to break and deform in the process of embossing, and it can be reused many times to reduce the production cost.
Application cases: Commonly used in the production of book covers, greeting cards, high-grade cartons, etc., such as some exquisite art book covers, limited edition greeting cards, etc., the use of magnesium alloy etching plate produced by the embossed plate can make the pattern and text more vivid, three-dimensional, giving people a strong visual impact.
Other applications
3. Anti-counterfeiting marking: the use of magnesium alloy etching plate can produce unique microstructure and pattern of anti-counterfeiting marking, these markings are difficult to copy, can effectively improve the anti-counterfeiting performance of the product. Such as in pharmaceutical packaging, electronic product packaging, the use of magnesium alloy etched plate produced by the anti-counterfeiting mark, consumers can identify the authenticity of a specific device or method.
4. Printed circuit boards: Although the current printed circuit boards mainly use copper and other materials, but magnesium alloy etched plate in some special requirements of the printed circuit board field also has certain application potential, such as in the weight, electromagnetic shielding performance of the aerospace, military and other areas of strict requirements of the electronic equipment, magnesium alloy etched plate can be used as an alternative material for research and application.
