Advantages of handheld fiber laser welding machine in the hardware industry

As my country’s hardware industry continues to increase nationalization and product quality under the policy of innovation-driven and quality-first guidance, China’s hardware industry has maintained rapid development in both production and sales. Hardware plays an increasingly important role in various fields. The more important the role, and the more and more types, bear the burden of product quality and experience.

The traditional hardware processing equipment uses a punching machine, combined with polishing, shearing and bending and other processes to form the final shape. This processing efficiency is relatively low, the mold making time is long, and the cost is high. The high emphasis on energy conservation and environmental protection has had a certain impact on the hardware processing industry.


The laser cutting machine is produced under the premise of the urgent need of such manufacturers. It is a modern processing equipment with good economic benefits. It not only reduces the processing time of hardware products, but also makes great progress in quality. It has a long-term effect on the hardware processing industry. significance.

The following briefly introduces the advantages of laser cutting machine:

1. Good cutting quality, reducing labor costs

The laser cutting machine uses the characteristics of laser non-contact processing, does not damage the workpiece, the cut product has no extrusion deformation, the processed product is of good quality, has no burrs, does not require manual polishing, saves unnecessary processing procedures, and optimizes labor strength.

2. Save mold investment and reduce production costs

The laser cutting machine can directly produce various hardware parts without molds, without mold consumption, and without repairing and replacing molds. It can save a large number of molds, save processing costs, and reduce production costs. It is especially suitable for processing large products.

3. High precision, effectively improving productivity

The laser cutting process appears as an alternative to "shear-punch". It has the characteristics of precision, flexibility, and efficiency. It can effectively process various complex parts. You only need to make the cutting graphics and import them into the control system. Cutting to a fixed size helps directly shorten the product processing and manufacturing cycle and effectively improve labor productivity.

4. Fast cutting speed, optimized working environment

The laser cutting machine cuts quickly, the equipment is stable when working, the noise is small, there is no dust, and it does not produce chemical substances harmful to the human body and the environment. It is also a kind of intimate protection for the operator, ensuring the clean and tidy production site, and reducing the number of subsequent stages. Investment reduces pollution, helps hardware companies to promote the optimization of the working environment, and conform to the tide of environmental protection.

5. Low maintenance cost and high cost performance

The maintenance of mechanical products is very expensive, and the laser cutting machine has stable performance, sturdiness and durability, can work continuously, is not easy to be damaged, and has a great advantage in terms of later maintenance costs.

For hardware processing companies, the choice of laser cutting machine manufacturers is a very important part. The equipment produced by good manufacturers can not only help companies produce better products, but also help companies control production costs and increase profits.


The laser equipment of Maanshan Durmapress Machinery Techology Co.,Ltd. has high electro-optical conversion efficiency, good beam quality, stable performance, and high cost performance. It can meet the needs of the hardware processing market, help hardware processing enterprises reduce procedures and construction periods, reduce mold investment, and improve work efficiency , While promoting the optimization of the working environment, effectively reducing costs.

In CO2 lasers, the main working materials are composed of three gases: CO2, nitrogen and helium. Among them, CO2 is the gas that produces laser radiation, and nitrogen and helium are auxiliary gases. CO2 lasers are widely used in the cutting industry.

One: Incentive mode. The carbon dioxide laser uses electrodes to excite carbon dioxide gas to generate laser light. According to the installation position of the metal electrode, it can be divided into DC excitation and radio frequency excitation.

Two: Laser frequency. The laser output is divided into pulse output and continuous output. The laser used for cutting and welding mainly adopts the pulse output method. The pulse frequency mainly affects the cutting speed and the roughness of the incision. To obtain high-speed cutting, high frequency is essential. At present, the frequency of carbon dioxide lasers produced by most manufacturers is within 5000 Hz.

Three: beam divergence angle. Strictly speaking, the beam divergence angle is not part of the content of the laser, but because the laser mode has a great influence on the far-field divergence angle, we will discuss it here. The influence of the beam divergence angle on the cutting quality is reflected in the width and slope of the incision. The smaller the divergence angle, the narrower the incision width, the smaller the slope, and the higher the quality.


Four: Laser mode. It is one of the most important indicators to measure laser quality. It can be divided into single mode, base mode and multimode. The fundamental mode is the TEM00 mode, and its exponents on the X and Y axes are both 0, so it is an ideal dot. The laser with TEM00 mode can obtain the smallest beam diameter, and obtain the smallest slit and faster cutting speed in the cutting process because of its small spot. The multi-mode is non-zero index in the XY direction, its beam quality is poor, generally only used for welding and not cutting.

Five: Laser cutting machine, laser power. Including peak power, energy stability and other factors. Different powers can cut through different thicknesses in the cutting of metal sheets. Take a 4KW laser as an example, it can cut 20mm thick carbon steel plates, or 15mm stainless steel 10mm aluminum alloys; while lasers above 5KW can cut 25mm thick carbon steel, Stainless steel can reach up to 20mm. Another indicator of power is power stability. Excellent cutting quality must be an excellent cut throughout. Long-term production is also a very important test for lasers. DC-excited lasers cause power attenuation under long-term working conditions due to electrode ablation. In addition, because the vacuum pump and turbo pump of some lasers are lubricated with lubricating oil, the lubricating oil contaminates the laser resonator cavity and shortens the life of the laser.

Laser cutting machine is a high-tech intelligent equipment integrating numerical control technology, laser cutting technology and inverter power supply technology. The development of laser cutting technology is based on the common progress of computer control, laser optics, power electronics and other disciplines. Among them, the numerical control control system plays a very important role, the following Guangyi Net will introduce three commonly used control systems.

PIC system

It belongs to an older board control system that can be integrated into an ordinary computer to run, and uses background software to control analog signal transmission. Although the control system is old, it is a completely Kaiyuan system.

Bochu system

The Bochu system is a laser cutting machine system developed by domestic personnel for the domestic market. It is a non-closed loop open element system developed for laser cutting machines below 2000W. The system is easy to operate, rich in functions, and simple to operate on laser cutting machines within 1000W. And other advantages, it is widely used by most domestic laser cutting machine manufacturers on laser cutting machines within 1000W. After years of upgrades and experiments, it is currently the most stable system configuration for laser cutting machines within 1000W.

PA8000 system

PA system is an open numerical control system (CNC) based on PC technology. Open CNC technology represents the most cutting-edge technology in the global numerical control field. Its advanced technology has been adopted by many famous automation companies in the world.
