WISCO-HGlaser has benefited a lot in the project appraisal meeting. We will adhere to the concept of green intelligent manufacturing, strive to advance towards the forefront of the industry step by step through continuous efforts and surpassing, and strive for a greater glory of manufacturing.

Laser technology helps the development of new green industry

With the rapid development of manufacturing industry, the application scale of various mechanical and electronic products has grown greatly. However, the environmental problems brought by industrial development have become an obstacle to people's healthy life. With the introduction of relevant policies, green environmental protection has become an important constraint of industrial development, and laser technology with unique advantages in environmental protection has ushered in a new development opportunity.

WISCO-HGlaser, a high-tech company dedicated to providing laser surface treatment and re-manufacturing technology systems and solutions, brought two main products, laser cladding and laser cleaning, at the LASER World of PHOTONICS CHINA held from March 20 to March 22. The cladding product line of WISCO-HGlaser includes traditional cladding, wide-band cladding and ultra-high speed cladding. After continuous adjustment and optimization of equipment and process, the efficiency of ultra-high speed cladding is nearly 70 times higher than that of traditional cladding, which is a highlight of new products of WISCO-HGlaser. The second generation laser cleaning equipment brought by WISCO-HGlaser is 20-30% smaller than that of the previous generation in volume, which not only enhances the portability, but also greatly improves the cleaning efficiency by improving the process, and is suitable for more working conditions.

Liu Jie, general manager of WISCO-HGlaser, said in an interview with OFweek laser network: "the State advocates the development of new industries with green and environmental protection, and laser processing is the leading direction to promote green and environmental protection, efficient processing and intelligent manufacturing. Owing to the requirements for green environmental protection and efficient processing, the industrial market is more demanding for equipment and supporting processes, which also leads to the overall rising trend of all kinds of laser industry, and the overall market capacity is larger. " Moreover, laser additive manufacturing and surface treatment need to have a very deep and detailed systematic research and control on the relationship between material composition, laser light source, laser power, time and speed, mathematical model, automatic control, etc. and relatively high technical threshold, bringing a promising technical development prospect. Through years of independent research and development, WISCO-HGlaser has developed four product lines, i.e. additive, reinforcement, texturing and cleaning, and its market scale ranks first among domestic similar enterprises.

Compared with additive manufacturing technology, the entry threshold of laser cleaning market is relatively low. On the one hand, the laser cleaning market has developed rapidly in recent years, on the other hand, the low-end market is highly competitive and homogenized. Liu Jie thinks: "practitioners and investors should be aware of the applicability of laser cleaning technology, and correctly master and use laser cleaning technology. For some industries, laser cleaning can replace manual cleaning and chemical cleaning, but we still need to pay attention to the development of core devices and the continuous improvement of technology level, and the laser cleaning technology is still in a forming period. As the earliest manufacturer and leader of laser cleaning equipment in China, WISCO-HGlaser focuses on guiding technological development and industry breakthrough. A special research group has been established for the development of laser cleaning technology, striving to break through more efficient laser cleaning equipment and technology and put them into the market in succession. " At present, after independent development, WISCO-HGlaser has formed a production capacity of 50W-1600W laser cleaning equipment full production line, and master all process parameters, which can meet the different needs of various clients.

Standard equipment of small power laser cleaning for WISCO-HGlaser

Before 2016, the industrial market did not pay enough attention to environmental protection. With the deepening implementation of the national environmental protection policy and the continuous recovery of the national economy, WISCO-HGlaser also brought gratifying performance growth. In 2018, the output and profit of WISCO-HGlaser doubled, and the original abundant production sites also faced the situation of "production can not catch up with the shipment". Expanding production capacity is a very important thing to WISCO-HGlaser at present.

Liu Jie said: "The development strategy of WISCO-HGlaser is very clear. We can design and manufacture many products in many fields, but we only focus on additive manufacturing and surface treatment to make it specialized and thorough. We will not blindly seek for greatness and perfection, respond to the call of the state, and let laser technology play the largest role in the green and environmental protection emerging industry, and become a leader in this industry."

Great news! WISCO-HGlaser took the lead in formulating the first national "CNC fiber laser disordered texturing machine" national standard

Recently, WISCO-HGlaser has taken the lead in formulating the national standard for "CNC fiber laser disordered texturing machine tool", which has been approved and released by the General Administration of Quality Supervision and the China National Standardization Management Committee and entered the announcement stage. Standard No.: GB/T 35356-2017, implemented on July 1, 2018.
(selected from China standard online service network)

It is understood that the standard is under the leadership and guidance of the Secretariat of the National Technical Committee for standardization of special processing machine tools, and with the active efforts of all members of the preparation team, after three years, it has finally been achieved. The issue of this standard solves and standardizes the problem that there is no national product standard for a long time before the roll laser disordered texturing equipment. It will play a good role in unifying and standardizing the precision inspection scale of similar products in China and improving the quality level of products.

With its leading technical position in the industry, WISCO-HGlaser takes the initiative to independently innovate and develop CNC laser disordered texturing machine tool, which can meet the production requirements of cold-rolled sheet steel and cold-rolled sheet steel in the iron and steel industry and the non-ferrous metal industry, and is suitable for the disordered texturing of the surface of working rolls of rolling mill, leveling machine and finishing machine. It has not only successfully solved the industry problems of laser texturing board surface quality (board surface stripe, reflection in a certain direction, etc.), but improved the impact of the textured board surface, enhanced the paint adhesion so that the texture of the textured board surface is similar to that of the electric spark and the overall product quality has reached the international advanced level. At the same time, 13 national patents have been applied in the research and development of this project, including 3 utility models and 9 inventions.
According to the actual development of the manufacturing technology of laser disordered texturing of roller in China, the successful implementation of the national standard GB/T 35356-2017 "CNC optical fiber laser disordered texturing machine tool" has a long-term strategic significance to meet the needs of China's economic development and improve the market competitiveness of the cold rolling industry. Moreover, it highlights that WISCO-HGlaser has solid technical strength and greatly improves the core competitiveness of the business market.

Introduction of equipment

The system is used for cold roll texturing and and meets the texturing requirements of various work rolls such as temper mill, finisher, rolling mill and tandem mill. With a high roller texturing efficiency, lifelong roller service, pollution-free laser texturing process and low noise, it is a new type of roller texturing technology and can replace the traditional shot blast texturing and EDM texturing. It has stable and reliable equipment and process, simple operation, high processing quality, good repeatability of laser texturing process, controllable texturing morphology, realizing disordered texturing, and meeting the needs of a variety of surface morphology. It is widely used in steel, aluminum, titanium and other industries.

Process introduction

The laser beam with high energy and high repetition frequency is focused on the roller surface to form a micro molten pool; the micro convex concave body is formed under the action of side blowing gas and centrifugal force, and the texturing lattice with high hardness is obtained by ultra fast cooling. It can make the roller after texturing have a high surface hardness, a controllable shape, and a long service life and improve the production efficiency of the rolling mill. The random signal is used to change the morphology and arrangement of the textured points randomly, so that the surface is of disordered pitted surface structure.
