目前，我國鋁電池行業發展迅猛，而鋁電池外殼制造技術也在不斷進步。鋁電池外殼制造工藝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藝处理，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。

　　制造精美的鋁電池外殼，需要經過以下工序：

　　1、鋁板切割。鋁板材料通常采用1000系列或者5000系列鋁合金材料。1000系列材料具有較好的焊接性能，而5000系列材料具有較好的抗腐蝕性能。鋁板材料的厚度一般爲1.2mm-4mm。

　　2、無毒塗料噴塗。爲了使鋁電池外殼具有良好的耐腐蝕性，外表面通常需要進行無毒塗料噴塗。目前常見的無毒塗料材料有聚氨酯材料、環氧樹脂材料等。

　　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藝。

　　4、冷却处理。冷却处理是在热处理工藝之后的工序。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、檢測質量。在制造過程中，爲了保證制造出來的外殼質量達到要求，通常需要對外殼進行質量檢測。常見的檢測項目包括尺寸檢測、表面檢測、性能檢測等。

　　以上就是铝电池外壳的制造工藝流程，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.
