Mg-Al alloy is one of the alloys. The low density of mg Al alloy improves its properties. The material has good stability, thermal conductivity, and is lighter and thinner.
All the lighter and thinner notebook computers will use the magnesium-aluminum alloy shell as their preferred material, not only because of its high strength, rigidity, and dimensional stability but also because of its excellent electromagnetic shielding and thermal conductivity, which can protect the computer to work normally and stably for a long time. The development trend of the notebook is more and more light. The density of magnesium-aluminum alloy is small, its strength is high and its rigidity is good. At the same time, excellent electromagnetic shielding also reduces the harm of electromagnetic radiation to the human body.
Compared with traditional desktop computers, notebook computers have the biggest advantage of being light and thin. Due to the narrow internal space of the notebook body, its cooling capacity is limited to some extent. Even if ultrabooks are equipped with low-power processors, the cooling effect will not be very good. Notebooks often high temperature, the most direct consequence is the automatic shutdown, the computer running faster and slower, which also means that the life of the notebook is reducing. For this reason, the cutting technology of notebook cooling holes is more and more concerned by manufacturers.
The disadvantages of the traditional drilling method are obvious
Taking the aluminum and aluminum alloy notebook shell as an example, when the manufacturer processes the heat dissipation hole, the traditional mechanical cutting method processes a workpiece in two seconds on average, and the processing time is long, so the consistency of the processing effect is difficult to be guaranteed, and problems such as slag scraping, burr, and deformation often occur along the cutting edge. In the long run, the production quality and delivery efficiency are seriously affected.
Magnesium aluminum precision laser cutting machine to solve your worries
For this reason, KING’S laser has launched a precision optical fiber laser cutting machine for magnesium-aluminum parts. At present, the laser cutting machine is the most advanced way to cut micro holes. Laser cutting efficiency is high, cutting quality is good, cutting surface is smooth and tidy, only need to set up the graphics to be cut in the computer program, a beam of light flashes, in a blink of an eye, the graphics will be cut well. According to the preliminary calculation, using laser cutting machines instead of traditional cutting equipment, the cutting time of a workpiece is shortened from 0.37 seconds to 0.22 seconds, and the processing efficiency is more than doubled.
The machine is characterized by smooth and beautiful cutting seams, minimal thermal deformation, the first continuous and fast curve cutting function and the shortest processing path optimization function in the industry, greatly improving the cutting efficiency, and powerful operation software function, which can achieve a simultaneous output of various working modes such as carving, cutting and micro-drilling of workpieces.
At present, KING’S laser vigorously promotes the precision cutting machine for magnesium-aluminum parts, which is widely used in precision sheet metal processing, electronic circuit PCB board, electrical appliances, glasses, precision accessories, advertising decoration, craft gifts, tool processing and other industries with high precision requirements.
