Sheet metal fabrication is one of the main business of Hongfa.compared with plastic enclosure or extruded aluminum box,it has a big advantage.

According to Wikipedia, "Sheet metal is used in car and truck (lorry) bodies, plane fuselages and wings, hospital tables, roofs for buildings (architecture), and many more applications.

The following is a discussion of how sheet metal plate is processed at a factory.

1. Blanking: There are several blanking techniques, mostly using CNC punch and laser cutting, depending on the varied drawings. Let's begin blanking each one one at a time.

First off, the edge of the work piece processed by NC punch may develop large burrs.

Second, the flat nature of the laser processing area makes it ideal for processing uniquely shaped work components. After blanking, be mindful to provide edges, corners, and burrs the appropriate grinding to make positioning during bending easier and guarantee consistency in product size across the same batch.

2. Enter the subsequent process after blanking. Processes used to treat different sheet metal components vary. Bending, riveting, spot welding, and other procedures are examples.

A. During press riveting, make sure the surface of the stud and the sheet metal component are flush and choose the die according to the height and size of the stud.

B. Bending: based on the size of the required bending material on the drawing, choose the bending tool and bending groove with the corresponding thickness.

C. Spot welding: To ensure a solid weld, bump welding must be done on the joint between the work piece and the work piece, and the welding position must also be precise.

Focus on A in accordance with the processing technique. In order to prevent interference after processing in other processes, and the following processing being unable to be finished, the parts with convex hull and segment difference must be processed first with the die.

Pay care to the following, per the processing process:

A. In order to prevent interference after processing in other processes, where the next processing cannot be finished, the parts with convex hull and segment difference must be processed first with the die.

B. You must first decide on the bending order. From inside to outside, tiny to huge, and special to ordinary are the general rules. 3. Sheet metal pieces will have weld scars on their surface after spot welding; these scars should be removed with a grinder.

3. After the bending and riveting process is completed, the workpiece shall enter the riveting process.According to the assembly and packaging process.

Pay attention to the following in accordance with the processing procedure:

A. In order to prevent interference after processing in other processes, where the next processing cannot be finished, the parts with convex hull and segment difference must be processed first with the die.

B. You must first decide on the bending order. From inside to outside, tiny to huge, and special to ordinary are the general rules.

D. Sheet metal pieces will have weld scars on their surface after spot welding; these scars should be removed with a grinder.
