Customization Process for Sheet Metal Electronics Enclosure

HSJ is a leading manufacturer of custom sheet metal electronics enclosures in China, offering a range of services from designing, material selection, process choosing, surface treatment, quality control, packing, online face-to-face confirmation, project meetings, and one-stop after-service. Our business includes power enclosures, energy enclosures, controller enclosures, solar enclosures, electric enclosures, medical enclosures, aircraft enclosures, industrial enclosures, and more.

Sheet metal electronics enclosure fabrication typically involves seven steps, which include designing, material selection, cutting, bending, welding, finishing, and assembly.


Design is the initial stage of sheet metal electronics enclosure fabrication, which includes developing a comprehensive design that satisfies the project's specifications and requirements. Typically, it takes 3-7 days to create a sample after the design has been approved.

Material Selection

After finalizing the design, the next step is to choose the appropriate sheet metal material, which is typically based on factors such as strength, durability, and cost. The materials that we usually choose and use are:

  • Aluminum (2A21/3003/5052/5083/6061/6082/8011)

  • Carbon Steels (Q235, SPHC, SPCC, SPCD, SPCE, ST, ST12, ST13, ST14, ST15, ST14-T)

  • Stainless Steel (304, 304L, 312, 316, 317, 321, 347, 904L, 440, 17-4ph, 430, etc.)

  • Copper (C1020, C1100, C2100, 2200, 2300, 2400)

  • Brass (H62, H65, H68, H70, H80, H90, C2600, C2680, C2700, C5210, C5191, C51000, QBe2.0, C1100, T2)

Sheet Metal Cutting

Sheet metal cutting is a crucial step in the fabrication process, where the sheet metal is cut to the required size and shape using a variety of cutting tools. Laser cutting machines and shears are commonly used to achieve precise cuts. At HSJ, we offer sheet metal cutting services for sizes ranging from 0.010.01mm to 20004000mm, with a thickness of less than 6mm. Additionally, we can accommodate special sizes and thicknesses based on customized requirements.

Sheet Metal Bending

After the sheet metal cutting process, the next step is sheet metal bending, which involves using a press brake to bend the metal into the desired shape. The press brake applies pressure to the metal using a punch and a die, which creates the bend. At HSJ, we can accommodate sheet metal sizes up to 3000mm * 6000mm and can also accept customized sizes. Our metal parts meet the CE and RoHS standards and are held to tight tolerances of +/- 0.005" (+/- 0.127 mm). For flat parts, the tolerance is +/- 0.010mm, while for bent parts, the tolerance is +/- 0.030mm.

Sheet Metal Welding

After shaping the sheet metal to the desired configuration, the cabinet structure is formed through sheet metal welding using different techniques such as TIG welding and MIG welding.


Once the welding process is complete, the cabinet undergoes sanding, cleaning, and finishing to achieve a sleek, polished appearance. Additionally, we can perform various customized finishes such as sandblasting, shot blasting, grinding, tumbling, polishing, brushing, spraying, painting, oiling, blackening, anodizing, electrochemical polishing, electroplating, depending on the customer's request.


Assembly is the ultimate stage in the fabrication process of the Electronics Enclosure made from sheet metal. It comprises fastening hardware and accessories like hinges, handles, and locks to the cabinet. After completion, a quality inspection is conducted, and the finished cabinet is shipped to the customer. We have successfully assembled cabinets for numerous clients, including those in the help, controller, and aircraft industries.

If you are seeking a high-quality sheet metal Electronics Enclosure, HSJ is undoubtedly the right choice for you. We offer a complete range of services, including design, processing, finishing, quality control, and customer service, all aimed at ensuring your satisfaction. We are committed to meeting your requirements and achieving your goals.
