Deep drawing is a cold-plastic unibody forming technology, often referred to in the industry as deep drawing or deep-drawing. Unlike traditional splicing processing methods, it does not require disassembling sheet metal for welding and assembly. Instead, it uses a complete sheet metal as raw material, stretching it at a constant speed through multiple passes using a die, allowing the metal material to flow naturally and plastically, directly forming a hollow, deep-cavity shell;The core standard for judging deep-drawn parts is straightforward: when the ratio of shell depth to inner diameter reaches 0.5 or higher, it is considered a standard deep-drawn part, which is the key difference between it and ordinary shallow-drawn shells.

The choice of material directly determines the quality of the finished metal casing and its application scenarios. We typically use special raw materials for deep drawing, including 304, 316L, and 430 stainless steel, 5052 and 3003 aluminum alloys, as well as high-quality cold-rolled steel and copper alloys. DDQ deep-drawn stainless steel offers superior ductility, resisting cracking and wrinkling during the drawing process, and boasts excellent corrosion resistance and sealing performance. Aluminum alloy, on the other hand, emphasizes lightweight design and high heat dissipation, making it ideal for new energy equipment and outdoor lighting applications. All raw materials are compatible with multi-pass drawing processes, maximizing the preservation of the metal's structural strength.

The seamless, one-piece structure is the core advantage of deep-drawn metal casings. Those familiar with industrial casings know that welded casings inevitably have weld seams, which can lead to water seepage, dust accumulation, oxidation, and leakage over time, affecting electromagnetic shielding and airtightness;Deep-drawn casings, however, are seamless and spliced ​​throughout, with a complete and continuous structure. This results in excellent waterproof and airtight performance with an extremely low leakage rate, effectively resisting external dust, moisture, and pressure, making them perfectly suited for demanding sealing conditions in sensors, energy storage batteries, and high-voltage equipment.

In terms of cost and mass production, the advantages of deep-drawing technology will become fully apparent in large-scale production. Many customers may feel that the initial investment in molds is too high, but once mass production begins, its cost-effectiveness far surpasses CNC machining and manual welding. Not only is material waste significantly reduced, but production efficiency is also extremely high, enabling a stable output of finished products with uniform specifications and appearance. Subsequent secondary processing, such as trimming, punching, flanging, and shaping, can be completed according to requirements, combined with surface treatments such as wire drawing, polishing, anodizing, and electroplating, balancing practicality and aesthetics.

Deep-drawn metal casings have significant performance and structural advantages and are widely used in the following fields:

Consumer electronics and new energy: such as mobile phone metal frames, shielding covers, earphone charging cases, and precision battery casings in aerospace, energy storage, and medical equipment.

Industry and sensors: various sensor casings, instrument protective casings, filter casings, etc.

Home appliances and automobiles: washing machine casings, air conditioner base plates, automotive chassis structural components, and body panels, etc.

Technical advantages: The seamless, one-piece molding structure provides excellent waterproofing and airtightness; furthermore, the internal crystalline structure of the metal is highly compressed after forming, resulting in an extremely robust casing.

Overall, deep-drawn metal housings, with their seamless, high-precision, high-protection, and mass-producible characteristics, have become the preferred solution for industrial precision housings; We support customized processing based on customer drawings and parameter requirements, adapting to the personalized dimensions and process requirements of various industries, providing stable, durable, and highly sealed metal protection solutions for equipment.
