Looking at the New Industry Opportunities Behind Laser Welders

Guidance signs are also called signs. As the name suggests, they are signs that indicate directions, including lobby signs, restroom signs, room number plates, information desk signs in hotels, restaurants, hospitals, airports, office buildings, shopping malls and other public places, as well as public welfare tips in outdoor parks. Signs, road signs, parking signs, etc., are mostly made of metal for the sake of simplicity, elegance, sturdiness and durability. With the continuous upgrading of the living environment, the guide sign is no longer an isolated existence, but has become part of the visual identity of a specific use area, and its appearance design is naturally extremely colorful.

The formation of a perfect metal guide sign requires a humanized design concept and exquisite processing and manufacturing technology. It must meet both practical requirements and aesthetic principles. The processing advantages of laser cutting are perfectly demonstrated in the field of metal guide signs.

Outdoors, metal guide signs are sturdy and durable, and are not afraid of wind and rain erosion. Laser cutting cuts out text and patterns on metal plates, which are unique and vivid, giving people a smooth and clear navigation experience. The laser cutting edges are smooth and burr-free. It ensures the overall aesthetics and makes the guide sign, a part of the urban environment facilities, a unique landscape.

In the metal processing market, laser cutting equipment is becoming more and more popular, the plate processing market is gradually compressed, the market is fighting a price war, and many processing manufacturers are turning to pipeline processing. With the rapid development of China's economy in recent years, it has also promoted the development of many industries. With the improvement of the epidemic and the economic recovery, the fitness equipment, home decoration furniture, kitchen utensils and bathrooms and other industries have developed rapidly.

For traditional saw blade cutting, it is almost impossible to complete a tube in 1-2 seconds, but laser cutting machines are easy to achieve. Analyze the principle from two aspects. The emergence of laser cutting equipment has brought subversive changes to the cutting process of the traditional metal pipe industry. Laser cutting machine has the characteristics of high automation, high efficiency and high output. Pipes of different materials do not need to replace the corresponding saw blade or stop midway, which is very suitable for large-scale production.

Laser marking machines use laser beams to mark permanent marks on the surface of a variety of different chemical substances. When purchasing a UV laser marking machine, much attention is paid to the marking speed of the equipment, because this directly affects the efficiency of processing order information. So, what are the factors that affect the speed of UV laser marking machines?

Generally speaking, the main reasons that affect the marking speed of UV laser marking machines are divided into two aspects. One is the equipment itself, and the other is the production and processing of product workpieces.

The main reasons for the equipment itself include laser frequency, laser spot mode and light diffusion angle, laser power, effective optical plastic surgery and auxiliary gas during processing. Customers should consider this aspect when purchasing a UV laser marking machine, and it is recommended to follow the recommendations of professional engineers for model selection. Another reason is mainly the marking density, marking width, marking depth and laser spot size during processing.

Marking density: In the case of the same format, the same light spot, and the same depth, the higher the marking density, the corresponding marking speed will be slower, because the density directly increases the marking area.

Marking format: The marking speed of large format is slower than that of small format, because the total offset area of 窶銀€逆he large format marking scanning galvanometer increases.

Marking depth: According to requirements, if you need to increase the depth of marking, you need to adjust the parameters of the UV laser marking machine and increase the power, current and other parameters of the UV laser marking machine. These are Will affect the marking speed.

Advantages of laser cutting machines in sheet metal processing Compared with laser cutting machines, traditional cutting machines have low efficiency and poor precision. They cannot process precision parts and require experienced technicians to operate them. However, laser cutters are different. Laser cutting has the characteristics of high precision, fast cutting speed, not limited to cutting patterns, automatic typesetting, material saving, smooth cutting, and low processing cost; laser cutting has small heat-affected zone, small plate deformation, and narrow cutting slit; the incision has no mechanical stress , no shearing burrs; high processing accuracy, good repeatability, no damage to the material surface; CNC programming can process any plan, and can cut the entire sheet in large format without opening a mold, which has the advantages of economy and time saving. It can process sheet metal, stainless steel, chassis and cabinets.

There are many machines and equipment used in sheet metal processing because there are many processes, mainly including lathes, milling machines, planers, drill presses, boring machines, broaching machines, grinders and polishing machines. These machines and equipment can be subdivided.

Before the equipment is put into use, its workplace should be clean and free of debris. The oil pipes, gas pipes, wires, cables, etc. on site should be cleaned to prevent them from being damaged by rubbing during operation. The joints of oil pipes, air pipes, etc. should be checked frequently to see if they are tight, loose, or damaged. If damaged, it should be replaced immediately.

Processing Depending on the sheet metal processing, the process flow is also very different. Initially, it must go through the processes of blanking, assembly, flanging, stamping, bending and welding. Professional sheet metal processing companies have more excellent technical personnel who can accurately perform processes such as blanking and cutting to reduce product errors. Machining tools, lathes and technicians have become essential requirements. Only with these can we do a good job in sheet metal processing.

The UV laser marking machine belongs to the series of laser marking machines, but it is developed using a 355nm UV laser. The machine uses the third-order intracavity frequency doubling technology. Compared with infrared lasers, the 355nm UV light focus spot is extremely small, which can greatly reduce the mechanical deformation of the material and has little processing heat effect.

Because the UV laser has an extremely small focus spot and a small processing heat-affected zone, it can be used for ultra-fine marking and special material marking. It is the preferred product for customers who have higher requirements for marking effects. In addition to copper materials, UV lasers are suitable for processing a wider range of materials. Not only does it have good beam quality, but it also has a smaller focus spot, which can achieve ultra-fine marking; it has a wider range of applications; the heat-affected zone is extremely small, so there will be no thermal effect, and there will be no material burning problem; the marking speed is fast and the efficiency is high; the overall performance of the machine is stable, the size is small, and the power consumption is low.

UV laser marking machine is mainly based on its unique low-power laser beam, which is particularly suitable for the high-end market of ultra-fine processing. It can mark the surface of packaging bottles of cosmetics, medicines, foods and other polymer materials with fine effect, clear and firm marking, better than ink jet coding and pollution-free; marking and scribing of flexible PCB boards; micro-hole and blind hole processing of silicon wafers; marking of LCD glass QR codes, surface drilling of glassware, marking of metal surface coatings, plastic buttons, electronic components, gifts, communication equipment, building materials, etc.
