目前，我国铝电池行业发展迅猛，而铝电池外壳制造技术也在不断进步。铝电池外壳制造工艺主要包括单壳型和双壳型两种。单壳型外壳主要由铝合金板材制成，外表面经过喷砂和涂装工艺处理，内部面经过防腐处理，整个外壳具有较好的耐腐蚀性。双壳型外壳主要由两个部分组成，一个是铝合金外壳，另一个是内壳。铝合金外壳与内壳之间通常采用密封胶进行连接。

　　制造精美的铝电池外壳，需要经过以下工序：

　　1、铝板切割。铝板材料通常采用1000系列或者5000系列铝合金材料。1000系列材料具有较好的焊接性能，而5000系列材料具有较好的抗腐蚀性能。铝板材料的厚度一般为1.2mm-4mm。

　　2、无毒涂料喷涂。为了使铝电池外壳具有良好的耐腐蚀性，外表面通常需要进行无毒涂料喷涂。目前常见的无毒涂料材料有聚氨酯材料、环氧树脂材料等。

　　3、热处理。为了使铝电池外壳具有良好的耐磨损和耐冲击性能，通常需要对外壳进行热处理工艺。

　　4、冷却处理。冷却处理是在热处理工艺之后的工序。它的作用是使热处理后的外壳材料冷却速度达到预定要求，从而使外壳材料达到预定的性能要求。

　　5、检测质量。在制造过程中，为了保证制造出来的外壳质量达到要求，通常需要对外壳进行质量检测。常见的检测项目包括尺寸检测、表面检测、性能检测等。

　　以上就是铝电池外壳的制造工艺流程，如果想要制造出精美的铝电池外壳，需要在每个工序都能够保证质量。

　　At present, the development of aluminum battery industry in China is booming, and the technology of aluminum battery casing making is also constantly improving. There are two main types of aluminum battery casing manufacturing process, single casing and double casing. The single casing shell is mainly made of aluminum alloy plate, and the outer surface is treated by sandblasting and coating process. The inner surface is treated by anti-corrosion process. The whole casing has better corrosion resistance. Double casing shell is mainly composed of two parts, one is aluminum alloy casing, the other is inner casing. The aluminum alloy casing and the inner casing are usually connected by sealing adhesive.

　　To make exquisite aluminum battery casing, the following steps are needed:

　　1. Aluminum plate cutting. The aluminum plate material is usually made of 1000 series or 5000 series aluminum alloy material. The 1000 series material has good welding performance, while the 5000 series material has good corrosion resistance. The thickness of aluminum plate material is generally 1.2mm-4mm.

　　2. Non-toxic coating spraying. In order to make the aluminum battery casing have good corrosion resistance, the outer surface usually needs to be sprayed with non-toxic coating. At present, the common non-toxic coating materials are polyurethane materials and epoxy resin materials.

　　3. Heat treatment. In order to make the aluminum battery casing have good wear resistance and impact resistance, the casing usually needs to be heat treated.

　　4. Cooling treatment. Cooling treatment is a process after heat treatment process. Its function is to make the cooling speed of the heat-treated casing material meet the predetermined requirements, so as to make the casing material meet the predetermined performance requirements.

　　5. Quality detection. In the manufacturing process, in order to ensure that the manufactured housing meets the requirements, the housing is usually subjected to quality detection. The common inspection items include size inspection, surface inspection, performance inspection, etc.

　　These are the manufacturing processes of aluminum battery casing. If you want to make exquisite aluminum battery casing, you need to be able to ensure the quality in each process.
