In electrical products, the parts processed by metal sheets account for almost 30% of all product parts. The traditional blanking, corner cutting, opening and trimming processes are relatively backward, which directly affect the product quality and production cost. The analysis is as follows:

1. A large number of molds are required for traditional punch processing. Parts of electrical products have many hole sizes and different shapes, especially single and non-standard products. The mold cost is high and the production cycle is long, which is not conducive to the production of single pieces and non-standard pieces.

2. The portable curve saw is used for opening, which not only has poor cutting quality and difficult size accuracy control, but also has high labor intensity, high noise, low production efficiency and high saw blade consumption.

At present, the optical fiber laser cutting machine is mainly used in the electrical industry to cut steel sheet parts in the appearance sheet metal part and the installation of complete electrical components. Now, many electrical plants have adopted this new technology, improved product quality, reduced production costs, reduced labor intensity, improved the traditional plate processing technology, and received better production benefits.

Compared with the traditional process, laser cutting has the characteristics of high precision, high material utilization rate and high production efficiency. Especially in the field of precision cutting, laser cutting has more advantages than traditional cutting. It can focus energy into small space, and use high-density energy for high-speed, non-contact and high-precision cutting, which is very suitable for the electrical industry. In electrical appliance production, laser cutting is helpful to improve processing quality, save processing links and processing costs, shorten the production cycle of electrical appliances, thereby reducing labor costs and production costs, improving processing efficiency, and improving product competitiveness.
