Anhui Sheet Metal Fabrication and Processing The process includes the following steps: material cutting, press-riveting/bending, spot welding, assembly, and packaging.
1) Material Cutting: The cutting method varies depending on the drawings, with common techniques including CNC punching and laser cutting. Next, we’ll go through each of these cutting processes in detail. After CNC punching, the edges of the workpiece may develop significant burrs.

2) Laser processing produces smooth cross-sections, making it highly suitable for machining workpieces with irregular shapes.
After blanking, pay attention to grinding the edges and burrs to facilitate bending alignment and ensure consistent dimensions across products in the same batch.
After blanking, the part proceeds to the next process. Different sheet metal parts require different manufacturing processes. These processes include bending, riveting, spot welding, and others.
Riveting: Select the die according to the stud’s height and dimensions, and ensure that when using the press, the stud is flush with the surface of the sheet metal part.
Bending: Select bending tools and bending grooves of the appropriate thickness according to the bending material dimensions specified on the drawing.
3) Spot welding for sheet metal fabrication and processing in Anhui: To ensure strong welds, spot welds should be performed at the joints between workpieces, and the welding positions must be precise.
According to the machining procedure, we should pay attention to the following points: 1. Areas requiring embossing and sections with significant cross-sectional differences should be machined first, so as to avoid interference with other processes after machining and ensure that subsequent operations can be completed smoothly. 2. Before bending, it’s essential to determine the bending sequence. As a general rule, the sequence should proceed from inside to outside, from small to large, and from special to common features. 3. After spot welding sheet metal parts, weld marks will appear on the surface. These weld marks should be removed using a grinding machine.
After completing processes such as bending and riveting, the workpiece proceeds to the assembly and packaging stage.
4) Anhui Sheet Metal Fabrication and Processing Brief Overview of the Expo and Industry
1. With the development of the automotive, telecommunications, IT, and daily hardware manufacturing industries, sheet metal fabrication and processing in Anhui is becoming increasingly popular, making it ever more essential to understand sheet metal processing.
2. The process of shaping metal sheets, profiles, and pipe fittings into parts with specific forms, dimensions, and tolerances—whether by manual or mechanical means—is known as sheet-metal fabrication. It is widely used in the production of ventilation and air-conditioning ducts and their components.
3. Most sheet-metal fabrication and processing parts in Anhui are made from sheet metal and pipe fittings. Due to their advantages—such as light weight, high strength and rigidity, the ability to achieve arbitrarily complex shapes, minimal material consumption, no need for machining, and smooth surface finish—they are widely used in both daily life and industrial production. Examples include buckets, pots, ventilation ducts, conveying pipelines, and automotive body panel fabrication. Additionally, these components can also be applied to exterior vehicle repair work.
4. Metal sheet processing typically refers to methods such as shearing, bending, rolling, and turning/machining into shape. Generally speaking, processes that use dies to achieve various types of deformation are called sheet metal stamping processes, while processes that involve manual or mechanical shaping of sheets are referred to as sheet metal forming.
