As the philosophy of green industrial development gains momentum, traditional chemical cleaning processes—plagued by issues such as environmental pollution and substrate damage—are increasingly struggling to meet the demands of modern industrial cleaning. Against this backdrop, the laser cleaning technology introduced by HauqHi (Shanghai) Connection New Technology Development Co., Ltd. is emerging as a new preferred choice in the industrial cleaning sector. Leveraging core advantages such as "zero chemical reagents, non-contact operation, and precise controllability," this technology is now being widely applied in scenarios ranging from parts derusting and weld seam cleaning to the removal of aluminum oxide layers.
HauqHi ’s laser cleaning technology is primarily categorized into two types: fiber laser cleaning and pulsed laser cleaning. Fiber laser cleaning employs a non-contact method; by directing a pulsed laser beam onto the dirt and oxide layers covering a metal substrate, it achieves precise cleaning without causing any damage to the underlying material. This method allows for selective area cleaning based on specific requirements and offers exceptional operational flexibility, supporting both handheld manual operation and integration with robotic arms for automated execution. Requiring no chemical reagents, this technology is safe, environmentally friendly, and features low operating costs; it is particularly well-suited for the surface treatment of products demanding high cleaning precision—such as automotive components and high-speed train car bodies.
Pulsed laser cleaning technology, conversely, is renowned for its "high power and high stability." Its instantaneous pulse power can reach megawatt levels (10⁶ W), with a pulse duration of merely 30 nanoseconds, enabling the rapid removal of stubborn stains and oxide layers. Furthermore, the system features a fully enclosed laser design that is highly tolerant of ambient humidity, eliminating the need for high-purity dry gases or desiccant consumption. With its compact footprint, the equipment is easily integrated into various production lines. To date, this technology has been successfully deployed in applications such as mold cleaning and pre-weld cleaning, providing robust support for enterprises seeking to boost production efficiency and reduce cleaning costs.
A representative from HauqHi Connection Technology stated: "Laser cleaning technology represents a pivotal direction for innovation within the industrial cleaning sector. Compared to traditional processes, it offers significant advantages not only in terms of environmental friendliness and cleaning precision but also in its ability to integrate seamlessly with automated production lines, thereby meeting the evolving demands of smart factories and Industry 4.0. Moving forward, we will continue to optimize the performance of our laser cleaning equipment and expand its application across sectors such as aerospace and rail transit, helping a wider range of industries achieve a green transformation in their production processes."
