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單殼型和雙殼型兩種。單殼型外殼主要由鋁合金板材制成，外表面經過噴砂和涂裝工藝處理，內部面經過防腐處理，整個外殼具有較好的耐腐蝕性。雙殼型外殼主要由兩個部分組成，一個是鋁合金外殼，另一個是內殼。鋁合金外殼與內殼之間通常采用密封膠進行連接。

　　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為1.2mm-4mm。

　　2、無毒涂料噴涂。為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涂料噴涂。目前常見的無毒涂料材料有聚氨酯材料、環氧樹脂材料等。

　　3、熱處理。為了使鋁電池外殼具有良好的耐磨損和耐沖擊性能，通常需要對外殼進行熱處理工藝。

　　4、冷卻處理。冷卻處理是在熱處理工藝之后的工序。它的作用是使熱處理后的外殼材料冷卻速度達到預定要求，從而使外殼材料達到預定的性能要求。

　　5、檢測質量。在制造過程中，為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。

　　以上就是鋁電池外殼的制造工藝流程，如果想要制造出精美的鋁電池外殼，需要在每個工序都能夠保證質量。

　　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.
