The aluminum box panels commonly used in the market are classified into three major categories according to different materials:
1. ABS resin is a copolymer of three monomers: styrene (S), acrylonitrile (A) and butadiene (B).
ABS resin can change the various properties of ABS resin by changing the ratio of the above three components; at the same time, it maintains the easy processability and excellent electrical properties of styrene; it has high surface hardness, high strength, and good pressure resistance. Elasticity and corrosion resistance, good chemical resistance;
2. PC is the abbreviation of polycarbonate, and PC engineering plastics for short. PC material is actually one of the engineering plastics we call. As a material widely used worldwide, it is also more commonly used in aluminum box construction;
3. ABS+PC, commonly known as ABS plus polycarbonate. It is one of the few materials that may be used in China. It cannot be spontaneously combusted. When burning in an external fire, small particles like polycarbonate will be deposited on the surface. The black color is lower than ABS. It is common in electrical devices and mechanical parts.
At present, the quality of aluminum boxes on the market is uneven, and the materials used for the box boards are even more diverse. Quality aluminum box body.
As the inner lining of one of the aluminum box accessories, it is a shock-proof material foamed from composite materials, which mainly serves to fix and protect the equipment in the box and reduce the impact force during transportation.
Lining is an indispensable accessory for aluminum boxes, and its production process is also more complicated. The production and processing process is mainly divided into five main steps: typesetting, plate making, mold opening, material, processing and forming. The specific details of the production process are very important. Among them, the three processes of plate making, mold opening, and processing are important in the production process, which determine the quality of the lining produced.
The main function of the aluminum box lining is to protect the contents of the aluminum box and prevent damage caused by squeezing, collision, etc. Nowadays, the demand for linings is increasing, and customers are more and more recognized for their fixed role. It is also very convenient for aluminum box manufacturers to customize the EVA lining. After determining the internal shape of the aluminum alloy box, typesetting, milling machine processing, simple bonding, and cleaning are completed to complete a lining product. Powerful aluminum box processing enterprises attach great importance to the research and development and production of such aluminum box linings, and have made great progress in technology.
Therefore, when users choose an aluminum box, in addition to the aluminum alloy profile used in the box, they should also pay attention to the quality of accessories such as lining, which is related to the overall performance of the aluminum box.
