Life and death game of laser cleaning machine manufacturers

When the traditional sand blasting technology and imported laser equipment are facing the dilemma of efficiency and cost, local enterprises are breaking the monopoly with technological innovation. The data of Dongguan Mould Factory shows that the domestic laser equipment has reduced the cost of single piece processing from 3.7 yuan to 0.8 yuan, and the yield has increased by 12%, revealing a new path of industrial upgrading.

Analysis of Three Benchmarking Techniques

Wuhan Xiangming: Standard Maker

The team from Huazhong University of Science and Technology has achieved full coverage of handheld devices at 100-2000W W. The dynamic focusing technology has improved the renovation efficiency of automotive sheet metal by 40%, and the cleaning roughness of aerospace aluminum alloy has reached 0.8μm (in line with AS9100D standard). Leading the formulation of industrial technical specifications and reshaping the industrial ecology.

Chongqing First Engraving: Intelligent Innovator

AI spot adjustment system realizes automatic parameter matching, and the qualified rate of high-speed rail bogie cleaning reaches 99.2%. The cleaning time of aerospace components was reduced from 3 hours to 45 minutes, achieving zero substrate damage.

Guangzhi Technology: Small and Micro Empower

9.5kg class small equipment can achieve the beam quality of m < 1.6, and the 18K gold oxide layer can be non-destructively treated with the measured power of 85W in jewelry workshop, and the equipment volume can be stored in the workbench drawer.

Double Breakthrough of Cost and Technology

The price of imported 300W equipment is 680,000 vs domestic 198,000. The measured nominal 2mm cleaning depth of Japanese model is actually only 1.2mm, while the output stability of domestic Ruike laser 200kW model is 1%, and the derusting efficiency of marine steel plate is improved by 3 times.

Enlightenment from the transformation of small and medium-sized enterprises

Common misunderstandings in hardware welding: metal distortion caused by high-frequency pulse (solved by gradual parameter technology at the beginning of engraving), out-of-control humidity (cost of Xiangming nitrogen auxiliary system +8%), and low qualified rate of fixed spot (92% from light to dynamic focusing). The case of cultural relics restoration shows that the imported equipment causes the loss of trace elements in bronzes, and the Millennium rust is 100% removed after switching to customized equipment, and the inscription reaches SSS level integrity.

Core technical barriers

The laser acousto-optic monitoring system of South China University of Technology reduced the damage rate of aircraft skin from 17% to 0.3%. Deqing optical AI algorithm reduces the over-kill rate of battery detection by 50%; The multi-wavelength technology of large family laser makes the cutting burr of flexible screen controlled to 3.8μm, and the yield is 99.6%.

The industrial window is urgent.

The one-hour cost of laser cleaning broke 15 yuan, and the cycle of equipment recovery was shortened to 8 months. Dongguan cluster data shows that the enterprise failure rate reached 43% in the three months after the late transformation. The technological revolution has arrived, and there is no time to hesitate.
