Sheet metal is a comprehensive cold working process for metal sheets, including cutting, punching/cutting/composite, folding, welding, riveting, splicing, forming, etc.
Usually, the three most important steps in a sheet metal factory are cutting, punching/cutting, and folding.

1. Metal plate production process


Metal sheet metal processing is called sheet metal processing. For example, using sheet metal to make chimneys, iron drums, oil tanks and kettles, ventilation pipes, large and small elbows, round corners, funnel-shaped shapes, etc., the main processes include cutting, bending, forming, welding, riveting, etc., which require a certain amount of geometric knowledge.
Modern sheet metal durable processes include: filament power winding, laser cutting, heavy processing, metal bonding, metal drawing, plasma cutting, precision welding, roll forming, metal sheet bending, forging, water jet cutting, etc.

2.Process functional requirements


The design of sheet metal parts should ensure that the stamping process is simple, the stamping mold is easy to make, the stamping quality of sheet metal parts is high, and the size is stable, while meeting the requirements of product functionality, appearance, etc. Detailed design guidelines for sheet metal parts can be found in the “Process Characteristics of Part Structure Design” and “Product Design Guidelines for Manufacturing and Assembly” published by the Machinery Industry Press.

3.Production process


Generally speaking, the basic equipment of sheet metal parts factories includes cutting machines (Changzheng Shear Machine), CNC punching machines (CNC Punching Machine)/lasers, plasma, waterjet cutting machines (Laser, Plasma, Waterjet Cutting Machine)/composite machines (Combination Machine), bending machines, as well as various auxiliary equipment such as uncoilers, leveling machines, deburring machines, spot welding machines, etc.

4. Processing scope

sheet metal toolbox, water purifier, automobile, self-service machine equipment, medical equipment casing, new energy, mechanical processing parts electric charging pile, etc
