Fiber laser cutting technology is widely used in elevator production

Industrial laser manufacturing equipment has been widely used in production lines of all walks of life in the past decade. Many articles and products around people are actually related to laser technology. However, because the manufacturing process is on the factory production line, many people do not know the role of laser technology. For example, in the construction industry, bathroom industry, furniture industry, food industry, etc., there are a lot of "traces" of laser applications. This article takes you to understand the laser technology used in the elevator products of common special equipment in the construction industry.

Rapid development of elevator industry
Elevator is a kind of special equipment that we can often contact and use in our life. It originated in western countries and was later widely used in high-rise buildings. It is also the invention of elevator that makes it possible for people to live and work in high-rise buildings. In other words, the elevator is also a means of transportation.
At present, the mainstream elevators in the market are vertical elevator and escalator elevator. The elevator elevator is mainly installed in high-rise buildings, high-rise residential buildings and office buildings, while the escalator elevator is usually several floors high, which is more common in shopping malls or subway places. The main structure of elevator includes car body, traction system, control system, door, safety protection system, etc. A large number of steel plates are used in the structure of the elevator, of which the elevator is mainly the door and car body, and the escalator elevator is mainly the wallboard on both sides. These metal components are the places where laser technology is mainly used in the elevator industry at present.

The elevator has a certain load-bearing capacity, and the use of metal materials for safety is the most guarantee. In the past, elevator manufacturers basically used traditional multi-station punch and saw blade machines to process plates. Due to the low efficiency of this method, and the steel plate trimming often needs to be polished or prone to errors, which is not conducive to the beauty of the elevator. The development trend of the elevator industry is mainly high-speed elevator technology, intelligent control and efficient cleaning technology. People‘’s requirements for elevators are increasing. In addition to basically using stainless steel plates, there are also requirements for decoration. Beautiful and gorgeous elevators highlight the grade of high-end office buildings and high-end western-style houses, and improve the value and taste of houses.

Laser is widely used in elevator production at home and abroad

After about 2005, China‘’s real estate has developed rapidly. Skyscrapers have sprung up one after another. The demand for elevators in China has increased significantly. Foreign famous brands such as Otis, ThyssenKrupp, Mitsubishi, Hitachi, Fuji, etc. have rushed to the Chinese market. These foreign brand elevators have already used CO2 laser cutting in elevator production. Since then, hundreds of elevator enterprises in China have gradually introduced laser cutting machines. With the promotion of optical fiber laser cutting machines after 2010, the price of laser cutting equipment has dropped significantly, and the power is higher and the speed is faster. In recent years, the elevator industry has introduced new optical fiber cutting machines. At present, the domestic elevator industry has almost popularized the use of laser cutting equipment. As some elevator manufacturers expand production and update equipment, it will continue to bring new demand for laser equipment.
At present, there is no requirement for the thickness of the steel plate of the elevator car body and door in the national standard, only the strength requirement, but generally speaking, 304 stainless steel is commonly used at present, with a thickness of 0.8mm, and some steel plates up to 1.2mm are also used. The 2000W laser can easily handle this thickness of stainless steel plate, and can also use 3000 W or 4000 W, which means faster speed. The laser cut is smooth and burr-free, which reduces the work of polishing in the later stage, and is conducive to the welding and splicing of the car body.

In recent years, China‘’s elevator industry has developed rapidly driven by investment in real estate, rail transit construction, airport reconstruction and expansion, etc. At present, China has become the largest elevator producer and consumer in the world. By November 2020, China‘’s elevator output will reach 1.14 million. It is estimated that the elevator output will reach 1.231 million in 2021, and the number of elevators in China will reach 8.447 million in 2021. China will maintain the number of elevators with an annual output of more than one million for a long time, which means that more than one million elevators adopt laser cutting technology every year. The huge elevator market brings good market space for laser cutting equipment.

Rakoncnc has focused on laser and CNC machine for more than ten years, and can produce various types of fiber cutting machines.
