Sheet Metal Fabrication Process Flow

Sheet Metal Fabrication processing is an industry term. Simply understood, it is to process different metal materials (carbon steel/cold-rolled sheet/hot-rolled sheet/spcc/stainless steel (201, 304, 316)/aluminum steel) according to their different needs. The required finished sheet metal parts, such as (chassis shell, machine tool shell, distribution box, control cabinet, network chassis cabinet, automotive precision parts, etc.).

High-precision sheet metal processing tolerance range: bending: 0-+/-0.1mm, CNC machining: 0-+/-0.1mm, laser cutting 0-+/-0.1mm

Common processes of sheet metal processing:

Part 1: Cutting

Laser cutting is one of the most common blanking methods in sheet metal processing. First, according to the size specifications of the finished sheet metal processing parts, the metal stainless steel and other plates are laser cut into the required size for later use. This process is collectively called blanking.

Part 2: Bending Parts

Bending is to carry out numerical control bending of the finished material according to the size specification of the sheet metal processing part, and how to prepare it for the next link of sheet metal welding.

Part 3: Welding

Welding is divided into manual welding or robot automatic welding. It is a process of welding the cut materials according to the processed finished sheet metal parts. This process is also dangerous and must be a master with certain experience. Operation, or use robot manipulator to complete, high efficiency and high precision.

Part 4: Surface Treatment

There are also many surface treatment processes, such as hot-dip galvanizing, cold-dip galvanizing, galvanized coloring, powder coating, sandblasting, anodizing coloring, blackening, polishing and brushing, etc. At the same time, the surface treatment is also precision stamping An important environment in sheet metal processing, which directly affects the appearance smoothness, precision tolerance and other effects of finished sheet metal parts.

Part 5: Paint

Baking paint is to put on a "vest" for sheet metal processing parts and replace them with new clothes according to different uses of sheet metal parts. Here is not only the change of color, but also the process of baking paint is very rigorous, such as temperature, time, paint color deployment, etc. very important.
