Sheet Metal Cabinets

Sheet metal has the characteristics of lightweight, high strength, electrical conductivity (can be used for electromagnetic shielding), low cost, and large-scale mass production performance. With the increasing use of sheet metal, the design of sheet metal cabinet has become an important part of product industry development. Mechanical engineers must be proficient in the design skills of sheet metal parts. Common sheet metal cabinets include power cabinets, network cabinets, server cabinets, and outdoor cabinets. As one of the leading sheet metal cabinets manufacturers, HSJ Fabrication will provide you various high-quality custom sheet metal cabinet services.

What is Sheet Metal Cabinet Fabrication

Metal cabinets are made of sheet metal, which are built through a fabrication process producing thin broad metal sheets. Sheet metal cabinets usually contain a rectangular structure and are equipped with doors. Besides, they also have various shelves or drawers. The door are often equipped with locking mechanisms for safety concerned.


HSJ Sheet Metal Cabinet Fabrication Progress

HSJ is one of the most professional sheet metal cabinet manufacturers in China. We have rich experience in sheet metal cabinet manufacturing &  export and specialized in providing All kinds of customized OEM, and ODM, especially on Designing, material choice, process, choosing, Surface treatment, QC, FQC, OQC, Packing, online face-to-face after-service, Project meeting for one-stop service. Business spread to Power cabinets, energy cabinets, controller cabinets, Solar cabinets, Electric cabinets, Medical cabinets, aircraft cabinets, industrial cabinets, etc.

Sheet metal cabinet fabrication typically involves several steps, which may vary depending on the specific project requirements. However, the following steps are some general ways involved in the sheet metal cabinet fabrication process:

1. Design: The first step in sheet metal cabinet fabrication is the design process. This involves creating a detailed design that meets the specifications and requirements of the project.

2. Material selection: Once the design is finalized, the next step is to select the appropriate sheet metal material. The material is usually chosen based on factors such as strength, durability, and cost. Below are the normal materials we choose and used:

  • 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)

3. Sheet Metal Laser Cutting: The sheet metal is then cut to the required size and shape using various cutting tools, such as laser cutting machines or shears. HSJ Sheet Metal Laser Cutting size from 0.01*0.01mm to 2000*4000mm size, thickness less than 6mm.

4. Sheet Metal Bending: After cutting, the sheet metal is bent into the desired shape using a press brake. This involves applying pressure to the metal using a tool called a punch and a die, which creates a bend in the metal. The size we normally do is within 3000mm * 6000mm. Accept customized sizes. Metals parts will be held to +/- 0.005" (+/- 0.127 mm), CE, Rohs standard.Tolerance on Flat parts, +/- 0.010mm ,the  bent parts, +/- 0.030mm.

5. Sheet Metal Welding: Once the metal has been bent into the required shape, it is welded together to form the cabinet structure. This can be done using various welding techniques such as TIG welding or MIG welding.

6. Finishing: After welding, the cabinet is sanded, cleaned, and finished to give it a smooth, polished look. As a customized request, can also do Sandblasting, shot blasting, grinding, tumbling, polishing, brushing, spraying, painting, oiling, blackening, anodizing, electrochemical polishing, electroplating, etc.

7. Assembly: The final step in the sheet metal cabinet fabrication process is assembly. This involves attaching any hardware or accessories, such as hinges, handles, and locks, to the cabinet. The finished cabinet is then inspected for quality and shipped to the customer. We have helped the controller, the aircraft company, etc. finished assembly successfully for many times.
