The Disadvantages of Traditional Precision Sheet Metal Processing and the Conditions often Encountered in Processing

The traditional precision sheet metal parts process is to use cutting, stamping, sheet metal bending, electric welding welding and other steps, as well as flame plasma cutting, sheet metal bending, electric welding welding process. In front of the order information of multiple types, small batch production, customization, high quality, and short lead time, it shows a clear unsuitability. The laser cutting process is produced as an alternative to "cutting-stamping".

1. How does the laser cutting process replace traditional precision sheet metal processing?

(1) The laser cutting process has the characteristics of flexibility and high flexibility, so it is used in the production of special-shaped (or complicated) spray processing, customized factory product workpieces and test products (parts or small and large batches), and slowly replaces part of the traditional precision sheet metal processing technology. Traditional sheet metal cutting machines and equipment occupy a very large market share in the sales market, although they also have their own unique advantages.

(2) However, compared with contemporary technologies such as laser cutting, the shortcomings are very significant, which greatly affects the company's competitiveness. (CNC machine tools) Shears are mainly used for straight cutting, and are only used for cutting sheet metal processing of parallel lines. (CNC machine tools/CNC punch presses) High-speed punch presses have restrictions on cutting thick steel plates with a thickness of more than 1.5 mm, and the surface quality is not good, the cost is high, and the noise is large. The traditional precision sheet metal processing customization is not environmentally friendly.

(3) Flame cutting is a traditional cutting method for precision sheet metal processing. Under the conditions of cutting thermal deformation, cutting total width, waste, and relatively slow production and processing speed, it is only suitable for the preliminary processing of precision sheet metal parts. Plasma cutting and high-precision plasma cutting are similar to flame cutting. When cutting cold-rolled steel plates, the cold deformation is very large, and the inclination is also large. When the precision is high, it is helpless and consumables are more precious.

2. What kind of situation does precision sheet metal processing often encounter?

There are usually many situations encountered in precision sheet metal processing. Here is a brief introduction to the many production process conditions that we usually pay attention to when precision sheet metal processing. I hope it can be helpful to everyone.

(1) Door panel precision sheet metal parts: Use the manufacturing method of long side and short side, and then open the production process hole at the relevant corner. The size of the production process hole is usually determined by the thickness of the plate.

(2) Precision sheet metal parts and cast iron parts: Use fixtures, holes or convex hulls to locate butt welding. In many butt welds that are difficult to locate, convex hulls or holes are usually used for positioning.

(3) Electroless plated parts of precision sheet metal parts: Usually, it is necessary to increase the production process holes at the corners of the electroless plated parts to facilitate the timely discharge of the chemical plating solution.

The purchase of precision stamping dies effectively guarantees the quality.
