We production/delivery time is short, and our service is very efficient.
Laser texturing technology involves using high-energy, high-repetition-rate pulsed laser beams that are focused and then defocused to irradiate the surface of the roll for preheating and strengthening. The focused spot of the beam is incident on the roll surface, forming a tiny molten pool. Simultaneously, an auxiliary gas with a set pressure and flow rate is applied to the tiny molten pool by a side-blowing device, causing the molten material in the pool to accumulate as much as possible at the edge of the pool according to specified requirements, forming a circular arc-shaped protrusion (peak number).

The small pits on the surface of laser textured steel plates are not interconnected, which is beneficial for oil storage and capturing metal debris during later stamping and forming processes. This good oil storage property prevents stamping scratches and ensures the deep drawing performance of the steel plate. It also results in a smooth surface of the stamped parts and reduces the amount of oil used for stamping.
The laser texturing morphology on the surface is uniform and controllable, with smooth surfaces accounting for 60% of the entire textured surface. This results in high flatness of the rolled steel plate, improving the surface finish and glossiness of the strip steel, as well as its reflection quality after painting. This enhances the competitiveness of the product for users and enables the production of laser mirror steel.
The laser texturing machine can be used with either a single fiber head or multiple fiber heads for light emission. The laser spot has a uniform energy distribution and possesses the desired characteristics for texturing, adapting to various complex texturing processes and texturing of various devices. It can be organically integrated with robotic arms, making texturing more flexible and convenient. The laser texturing machine is suitable for texturing the surfaces of stainless steel, titanium alloy, aluminum alloy, and other similar materials, and is widely used in industries such as aviation, aerospace, marine, weapons, electronic components, sensors, and precision machinery.
Through the core pulsed laser output, each laser texturing point can be achieved in a disordered manner. Combined with the texturing process, texturing effects can be developed to meet different Ra/RPc value requirements.
The laser texturing equipment features a pulse frequency of up to 100kHz, boasting a processing efficiency significantly higher than traditional acousto-optic modulated YAG laser texturing equipment, thus meeting factory production requirements. It is capable of fine processing or heating fragile objects.
Under high-efficiency machining conditions, the roughness parameters can be adjusted by directly controlling the laser power, achieving an adjustable Ra value range of 0.5~20μm.
The laser texturing equipment has solved the problem of deviation in the roughness of the roll surface caused by the original equipment's flying light path.
Fiber laser heating exhibits excellent controllability and tunability. By adjusting parameters such as laser power, pulse width, frequency, and spot size, the heating process can be flexibly controlled to meet the requirements of different materials and applications.
For the sake of equipment safety, we have equipped with heavy-duty lathes and roll brackets that exhibit good stability, and have implemented an electronic sensing anti-collision system as well as a laser safety logic control system.
The laser texturing equipment integrates the laser device and the machine tool, significantly reducing the equipment footprint.
Compared to electric spark texturing equipment and shot peening texturing equipment, the operating cost of laser texturing equipment is lower.
Equipped with a numerical control system, it features a "one-click texturing" function, making the equipment easy to operate and achieving high machining accuracy.
This equipment integrates a laser and a machine tool, utilizes fiber laser technology, and boasts high stability.
After years of accumulation, we have developed self-protection mechanisms for equipment in various usage environments, enabling it to operate in harsher conditions.
The equipment has high integration, good stability, and is very easy to maintain.
