High-precision Henan sheet metal fabrication is suitable for processing both large- and small-batch production items.

Henan sheet metal processing is suitable for both large- and small-batch production of manufactured goods and boasts advantages such as short processing cycles, high precision, and excellent uniformity. To transition from conventional sheet metal processing to high-precision machining, the following conditions must be met: equipment replacement, product upgrades, and improvements in management practices.

Compared to traditional sheet-metal processing, sheet-metal fabrication offers advantages in terms of high quality and superior performance. The modular, component-based design facilitates large-scale production and helps control costs. The diversity of product types and customizable designs broaden the application scope of gear-reduction motors. Gold deposits have extremely stringent requirements, necessitating strict adherence to tolerances. If assembly deviations occur, the products generally fail to meet specifications. Moreover, their tolerance requirements are even more stringent than standard values.

Since the 21st century, thanks to advances in technology and rising living standards, sheet metal fabrication in Henan has become widely used in our daily lives. For instance, computer system casings, chassis, cabinets, and enclosures—all these products involve sheet metal processing, a method of working with metallic materials. So, what specific processing techniques are included in sheet metal fabrication? Here, the editor will provide you with a detailed explanation of the sheet metal fabrication production process.

Detailed Introduction to the Sheet Metal Processing Production Process in Henan

CNC cutting

After receiving the engineering drawings, we select an appropriate blanking method based on the unfolding drawings and the batch size. These methods include laser cutting, CNC machining, shearing, and die-cutting, among others. We then proceed accordingly according to the engineering drawings. For certain special-shaped workpieces and irregularly shaped holes, the edges may exhibit significant serrated patterns, necessitating subsequent grinding and polishing operations.

Grinding and polishing

After the workpiece is blanked, the edges, burrs, adhesive spots, and adhering skin must be properly trimmed. At the contact points of the CNC blade, use a flat file for trimming; for workpieces with larger burrs, use a grinding machine for finishing.

Riveting, tapping, welding, step differences, and deburring;

After the blanking process is completed, the workpieces proceed to the next manufacturing stage. Depending on the specific processing requirements, different types of workpieces are routed into their respective process flows. These processes include bending, press-riveting, reverse-flanging and tapping, welding, deburring, and step differences. Sometimes, after one or two bends have been performed, it’s necessary to securely press-fit nuts or bolts. Additionally, there’s a dedicated area for deburring using grinding tools; it’s important to understand that this area must be processed first to avoid interference with other processes that might otherwise occur if processed later, thus ensuring that the required operations can be carried out smoothly. If the upper cover or lower shell features snap hooks, and laser welding isn’t required after bending, these snap hooks must be properly formed before the bending operation begins.

Bending processing

When bending, you should first determine the required milling cutter and cutter groove based on the dimensions specified in the design drawings and the thickness of the raw material. It's crucial to ensure that the product does not collide with the CNC cutting tool, which could cause deformation. The choice of the lower die is particularly important in this regard. The selection of the upper die, on the other hand, depends on the thickness of the wood. Next, you need to clarify the bending sequence. As a general rule, bending should proceed from the inside out, starting with smaller bends before moving on to larger ones, and giving priority to special bends before tackling standard ones.
