Whether it is a washing machine, electric pressure cooker, rice cooker, etc., household appliances that are closely related to our lives and diet are playing an increasingly important role in the home. And these appliances without exception will involve the material of stainless steel.
The application of stainless steel products in the home appliance industry are mainly washing machine inner tubs, water heater inner tanks and refrigerator linings. Because stainless steel has excellent durability, strength and processability, it also has a simple appearance and texture. Many refrigerators and range hoods The outer shell is also made of stainless steel.

At present, the output of major household appliances in my country has leapt to the forefront of the world. The output of refrigerators and washing machines accounted for more than 40% of the world, air conditioners and microwave ovens accounted for about 70% of the world, and small household appliances accounted for nearly 80% of the world. It has become a major manufacturer and main supplier of home appliances in the world. country. From 2014 to 2016, the output of my country's main household appliances (including washing machines, refrigerators, and air conditioners) was 320 million, 320 million, and 330 million units, respectively.
According to the "Thirteenth Five-Year Plan" goal, by 2020, the GDP and per capita income of urban and rural residents will double from 2010. The continuous increase of residents' income will drive the improvement of residents' living consumption. The application has a large potential market, and this also brings new challenges to the processing technology of stainless steel products.
The traditional stainless steel cutting process has problems such as tool wear, low processing efficiency, and easy to produce burrs, surface roughness, and deformation. In contrast, the advantages of laser cutting technology have become more prominent and have become the common choice of many stainless steel processing enterprises.
Advantages of laser cutting
1. No processing stress, no deformation of the workpiece
Cutting with laser cutting equipment is not affected by the hardness of the material. This is determined by the characteristics of the laser, which is an advantage that traditional equipment cannot match. Laser cutting can cut steel plates, stainless steel, aluminum alloys, and hard alloy plates without deformation. .
2. No need for secondary treatment, high processing efficiency
The stainless steel plate is processed by laser cutting equipment, and the non-contact processing method is adopted, which will not affect the deformation of the workpiece, and will not affect the progress of the next process. After laser cutting, there is no need for secondary processing, and the cutting surface is smooth.
3. Better positioning accuracy and better cutting effect
The laser beam is focused into a small spot, so that the focal point reaches a high power density. The material is quickly heated to the degree of vaporization, and the evaporation forms a hole. The beam quality is good, and the positioning accuracy is better, so the cutting accuracy is higher.
4. No tool wear, low maintenance cost
The laser cutting machine is used to cut stainless steel without loss, the cutting photoelectric conversion rate is high, and the processing cost is lower. The fiber laser cutting machine is maintenance-free.
Among the many laser cutting machine brands, HG Laser has the leading quality and superior cost performance. The new product MARVEL6000 series laser cutting machine has been popular in the market as soon as it is launched and has become the leader in flat fiber laser cutting machines.
● The core light source of the equipment is manufactured independently, and the procurement cost is reduced by 15%-20%;
● With ultra-high cutting efficiency, 600 round holes with a diameter of 2mm can be cut per minute for 1mm plates;
● Covering 100% of metal material blanking needs, effectively meeting various needs in home appliance processing, and helping Chinese home appliance brands move toward higher-end.
