What Is Sheet Metal Fabrication

Sheet metal is a comprehensive cold fabrication process for metal sheets (usually below 6mm), including shearing, punching/cutting, folding, welding, riveting, splicing (such as sheet metal enclosure), forming (such as car body), etc. Its remarkable feature is that the thickness of the same part is consistent.

Generally speaking, the basic equipment includes shearing machine, laser cutting, CNC punching machine, bending machine, and various auxiliary equipment such as clamp fabrication and welding. Such as: drilling machine, riveting machine, welding machine, etc.

According to different fabrication methods, it is usually divided into two categories:

Non-mold fabrication: the process of fabrication sheet metal through NCT (numerical control punch), laser (laser), folding machine, riveting machine and other fabrication tools is generally used for sample production, and the cost is relatively high;

Mold fabrication: Through fixed molds, sheet metal is processed. Generally, there are blanking molds and forming molds, which are mainly used for mass production, and the cost is low.

Sheet metal fabrication plant process

Sheet metal fabrication is the fabrication of sheet metal. The sheet metal fabrication process is complex and diverse, mainly including cutting and blanking, blanking, bending and forming, etc.

At the same time, according to the customer's drawing design requirements, we can provide services such as laser cutting, spraying, silk screen printing, and assembly.

Spraying/silk-screen Fabrication

Spray fabrication

Spraying fabrication is after the surface treatment, and the product is sprayed.

When spraying, the workpiece is first hung on the assembly line, and the dust stuck on the surface is blown off with the air pipe.

Enter the spraying area to spray, after spraying, enter the drying area along the assembly line, and finally remove the sprayed workpiece from the assembly line.

The main spraying methods are manual spraying and automatic spraying.

China sheet metal fabrication factories can provide plastic spraying process. The finished product has a good surface and meets environmental protection requirements. It has strong surface adhesion, is not easy to burn, can protect the metal surface for a long time, and has a much longer service life than the painted product, but Color options are less.

Silk screen fabrication

Screen printing is to print corresponding text, characters, patterns, logos, etc. on sheet metal products through screen printing, making sheet metal products more distinctive.

The screen printing method is flexible and diverse, and can be printed on multiple planes. The adhesion is strong, the screen printing content is not easy to fall off, and the gloss is long-lasting, which can be maintained outdoors for a long time.

However, it is mainly printed on a flat surface, and cannot be printed on a curved/concave-convex surface. Jiesu can support CAD/CRAWDRAW to draw silk screen files.

At the same time, for screen printing, one screen has one color, and the number of colors will affect the number of screens and the cost of screen printing. Therefore, it is recommended to choose a single color or design as few colors as possible to control the cost of screen printing.
