Understand the basic flow and technology of sheet metal processing in Suzhou

Sheet metal processing refers to the process of processing metal sheets through cutting, punching, folding, welding and other processes to produce metal components or parts that meet the design requirements. Sheet metal processing plays a very important role in the manufacturing industry, widely used in machinery manufacturing, electronic equipment, communication equipment, automotive industry and other fields.

The basic process of sheet metal processing mainly includes: design confirmation, material preparation, programming, material cutting, stamping, welding, assembly, surface treatment, quality inspection and other major steps.

The first is the design confirmation stage, according to customer needs and requirements, product design confirmation and process selection, including the selection of materials, the design of external dimensions, and the determination of processing technology.

Then comes the material preparation phase, preparing sheet metal and other required parts according to the design requirements. Under normal circumstances, the commonly used materials are mainly cold-rolled plate, hot-rolled plate, galvanized plate, aluminum alloy plate and so on. The selection of materials should take into account the use of the product environment, mechanical property requirements and economic costs and other factors.

Next is the programming layout stage, through computer aided design software (CAD) to arrange the product, optimize the use of materials, reduce waste, improve production efficiency.

Then is the material cutting stage, according to the results of the discharge, the metal sheet is cut by a shearing machine, and the whole sheet is cut into small pieces of the required size and shape.

Then is the stamping forming stage, according to the shape requirements of the product, the use of punches to form small sheets, such as punching, bending, stretching, concave and convex. The punch press is the most commonly used equipment, which has the characteristics of efficiency, accuracy and stability.

This is followed by the welding assembly stage, where the various parts are splice through the sheet metal welding process to form a complete product. Common welding methods are spot welding, gas welding, pulse welding, laser welding and so on.

Then is the surface treatment stage, the product surface polishing, spraying, electrophoresis and other treatments to improve the appearance of the product quality and anti-corrosion performance.

Finally is the quality inspection stage, the finished product quality inspection, including dimensional deviation, surface quality, assembly accuracy and mechanical properties and other aspects of the test and evaluation.

In general, the basic process of sheet metal processing mainly includes design confirmation, material preparation, programming, material cutting, stamping, welding and assembly, surface treatment and quality inspection. Each link requires professional technicians and advanced equipment to complete, in order to ensure the quality and performance of the final product. Although the process of sheet metal processing is simple, there is a wealth of professional knowledge and technical requirements behind it. Sheet metal processing industry in continuous development, and constantly introduce new technology and equipment to meet the needs of the market.
