Optical fiber laser marking machine

Optical fiber laser marking machine is the use of laser beam on a variety of different materials on the surface of the permanent marking. The effect of marking is to expose a deep layer of material by evaporation from the surface, or to“Carve” a trace by causing a physical change in the surface material by light energy, or to burn off a portion of the material by light energy, display the required etching patterns, text, bar code and other graphics. Suitable for all kinds of metal materials and some non-metal materials (high-ignition plastics, oxides, electroplating, coating, ABS, epoxy, ink, engineering plastics, etc.) .

Portable laser welding machine

Hand-held laser welding machine, using hand-held welding gun instead of the previous fixed light path, hand-held welding, flexible and convenient, longer welding distance, to overcome the limitations of the workbench space, when the workpiece size is not uniform can not be used in the case of automatic welding. Mainly for large workpiece, fixed position such as inside right angle, outside right angle, plane weld welding, welding heat affected area is small, deformation is small, and welding depth is big, welding firm. Is a long-distance welding of large parts of a more flexible new welding process

Convenient installation, simple use, no need of pipeline installation, and can be used as long as the air outlet is connected and the power supply is connected. With attractive appearance, reliable quality and excellent performance, the air quality of the integrated system has been significantly optimized. The excellent "all-in-one machine" solution integrates the screw compressor, refrigerated dryer, precision filter, air storage tank and other major components of the air compression system, providing customers with "key project" solutions.

Huada Permanent Magnet Frequency Conversion Screw Air Compressor

Equipped with ultra-efficient permanent magnet motor and intelligent frequency conversion control system, SED + series has passed GB19153-2019 national standard level I energy efficiency certification, ISO quality system certification, China quality inspection and other authoritative certifications, and its energy saving and quality are guaranteed. The energy efficiency far exceeds the first-class standard. It adopts the third generation of asymmetric tooth type, high-efficiency two-stage compression screw host, 17-18 bearing structure, large rotor, low speed, and greatly improves the gas production. The reinforced shell is made of high-strength cast iron, thickened and reinforced to reduce the vibration of the main engine and improve the service life of the main engine. The cooling system adopts a bionic fan with large air volume, which makes the cooling air volume and pressure more stable and the airflow noise lower. The frequency conversion fan can be better applied to various environments, so that the energy-saving effect of the machine is better, the service life of the cooler can be prolonged, and the deformation stress impact formed by the alternation of cold and heat of the aluminum heat exchanger can be reduced.

Huada permanent magnet double-stage frequency converter screw machine

TVD + series screw machine is equipped with special air compressor control panel and high-performance special display screen, which can monitor all operating parameters in real time. Intuitive interface, simple operation, fast response, and durable panel, suitable for all kinds of industrial environments. The system precisely controls the frequency converter through 485 communication frequency writing technology, with rapid response and high adjustment accuracy. Compatible with all frequency converter equipment supporting MODBUS RTU protocol, users have higher flexibility in selection and integration. The machine has built-in perfect motor protection mechanism, which has multiple electrical protection functions such as phase loss, overload, imbalance, too high and too low voltage, so as to effectively guarantee the safe operation of the motor and prolong the service life of the equipment. Vertical oil separator tank design, external oil separator is convenient for maintenance. Adopt better flow rate and structure design, increase the capacity of oil separation core, long life, high load, low pressure difference. The cooling system adopts a bionic fan with large air volume, which makes the cooling air volume and pressure more stable and the airflow noise lower. The high efficiency fan is quieter, which can prolong the service life of the cooler and reduce the deformation stress impact caused by the alternation of cold and heat in the aluminum heat exchanger.
