At present, as the global manufacturing landscape undergoes profound changes, the national "15th Five Year Plan" is taking a forward-looking perspective, anchoring a number of leading emerging pillar industries such as integrated circuits, aerospace, new materials, biomedicine, and low altitude economy. These industries are not only the core manifestation of national competitiveness, but their development height is also closely related to the precision manufacturing capabilities behind them. It can be said that their production process itself represents the "ceiling" of modern industrial manufacturing.

The core of high-end manufacturing often lies in its precision, efficient, and non-destructive processing capabilities for extreme performance materials such as monocrystalline silicon, silicon carbide, carbon fiber composite materials, high-temperature alloys, and medical degradable metals. However, traditional processing methods often struggle to meet these almost stringent requirements, with efficiency bottlenecks, stress damage, thermal effects, tool wear, environmental pollution A series of "bottleneck" problems have become key obstacles restricting industrial upgrading and product performance leap. The upgrading and replacement of industries urgently require a revolution in underlying processing technology.

In this breakthrough battle of manufacturing capability, laser, as the "fastest knife", "most accurate ruler" and "most agile tool", is evolving from an "advanced technology" to an "indispensable basic manufacturing capability". Guanghui Laser, as an innovator deeply rooted in the field of fiber laser technology, is providing deterministic solutions for strategic industries to solve core manufacturing pain points through a series of "hardcore" innovations.

01Common pain points of high-end manufacturing:The limitations of traditional processing and general-purpose lasers

Whether it is the carving of micro level circuits, the formation of complex aerospace titanium alloy components, or the manufacturing of biodegradable scaffolds, emerging pillar industries generally face the following challenges:

The dilemma of difficult processing of materials

Highly reflective material:Copper, gold, aluminum alloys, etc. are widely used in integrated circuit lead frames, low altitude economic motor housings, and aerospace pipeline systems. These materials have extremely low absorption rates for common near-infrared lasers. During traditional laser processing, a large amount of energy is reflected, which not only reduces efficiency but also easily damages the optical system and workpiece surface, resulting in unstable processing and poor quality.

Thermal sensitive material:Such as medical polymers, brittle semiconductor materials, and special composite materials. Traditional hot processing techniques, such as arc welding and plasma cutting, require a large heat input and a wide heat affected zone, which can easily lead to deformation, microcracks, material deformation, and damage to product performance and yield.

Heterogeneous material connection:Such as aluminum steel connections in lightweight car bodies and ceramic and metal packaging in electronic devices. The physical properties of different materials vary greatly, and traditional connection methods are prone to producing brittle intermetallic compounds, resulting in low joint strength and poor reliability.

High precision and cutting-edge processing tasks

Precision machining requirements:The miniaturization of integrated circuits requires ultra-fine cutting and drilling; Biological scaffolds require complex three-dimensional microstructures. Traditional mechanical processing has problems such as tool wear and stress introduction; Ordinary lasers are limited by beam quality (M ² factor), making it difficult to achieve high power while maintaining a very small focused spot and excellent depth of focus, which limits further improvement in machining accuracy.

Requirements for "non-destructive" processing:The key components of aerospace require almost perfect welds, without pores, cracks, or splashes; The cutting requirements for high-end display panels include no micro cracks or slag on the edges. Any minor machining defect can lead to the scrapping of expensive components and even cause significant safety hazards.

Efficiency and Cost Balancing Technique

While pursuing ultimate quality, industrial scale production also has strict requirements for efficiency and cost control. Traditional multi pass processing or reliance on imported expensive special equipment results in long cycles and high costs. Ordinary lasers have poor stability and narrow process windows when processing high reactive materials, requiring frequent debugging and maintenance, indirectly pushing up production costs.

02The way of laser breaking through walls:How does Guanghui's core technology directly address pain points

In response to the systemic challenges mentioned above, Guanghui Laser does not provide a single device, but has developed a systematic solution based on high brightness fiber lasers and targeted process packages as bridges.

【 Core cornerstone 】 High brightness fiber laser technology - smaller spot, stronger energy

The core of Guanghui Laser's independently developed high brightness fiber laser technology is to significantly improve the brightness of the laser. Brightness is a key physical quantity for measuring the energy concentration of a laser beam, determined by both output power and beam quality (M ²). Guanghui has achieved excellent beam quality (M ²<1.1) close to the diffraction limit while ensuring high power output through its unique 976nm pump technology and fiber design.

For precision machining (such as IC and medical): achieving ultra-fine cutting, drilling, and welding at the micrometer level, with a very small heat affected zone, truly achieving "cold processing" and protecting the structural integrity of heat sensitive materials.

For deep penetration welding (such as aerospace): The extremely high energy density can instantly vaporize the material to form deep and narrow "small holes", achieving high-quality welding with a large aspect ratio and low deformation, high weld strength, and few defects.

For efficiency improvement: High energy density means that processing can be completed at a faster speed or with lower average power to achieve the same effect, significantly improving processing efficiency and reducing energy consumption.

[Key Process] ABR Anti High Reaction Technology - A Powerful Tool to Conquer "Mirror" Materials

Faced with the "enemy" properties of highly reflective materials such as copper and gold, the ABR (Anti Back Reflection) intelligent anti high reflectivity technology of Guanghui Laser provides a fundamental solution.

In the processing of high reflectivity materials, once an excessively high return laser enters the laser, the "ABR ultra strong anti high reflectivity technology" will perform three-layer stripping on the return light. Add a detection and stripping device for the first level of return light to the output head, which can detect and strip the return light in the first time; Before entering the collimator, a detection and stripping device for secondary return light has been added, gradually stripping the return light in stages to ensure that it does not enter the interior; There is also a secondary detection and stripping device for returning light in front of the red light, which protects the red light indicator from damage and reduces the damage of returning light to the laser resonant cavity.

Breakthrough brought about: This has transformed laser processing of highly reactive materials from the past "high-risk, low yield" to "stable, efficient, and high-quality". Whether it is copper foil welding for new energy batteries or aluminum alloy fuselage processing for low altitude economic aircraft, perfect results with no spatter, low porosity, and high consistency can be obtained, greatly improving the yield rate and significantly extending equipment maintenance intervals.

[Quality Assurance] Intelligent Anti Splashing and Process Database - From "Experience" to "Science"

Splashing is a common defect in laser welding, which not only pollutes the workpiece and lens, but also may hide internal defects such as lack of fusion. Guanghui Laser has developed intelligent anti splash control technology through in-depth research on melt pool dynamics. By precisely controlling the start and stop of laser pulses, the slope of power climb, and airflow protection, the generation of splashing is suppressed from the source.

More importantly, Guanghui Laser has consolidated years of successful processing experience in aerospace, new energy, medical devices, and other fields into a vast industry-specific process database. This database is embedded in the device intelligent control system. Users only need to select the material type, thickness, and process target, and the system can automatically match the optimal parameter set that has been verified through massive validation, including power, speed, waveform, swing mode, etc. The "experience" of top craftsmen is transformed into the "standard capability" of each device, greatly reducing the application threshold of high-end processes and ensuring the ultimate stability and repeatability of processing results.

03Empowering the New Pillars of the 15th Five Year Plan:Value presentation of specific scenarios

Integrated circuits and new materials: penetrating the "high anti" barrier

In the field of advanced packaging, microfabrication of high reflectivity metals such as copper and gold is the core process. When ordinary fiber lasers process high reflectivity metals, most of the energy is reflected, which not only results in extremely low processing efficiency and astonishing energy consumption, but also causes fatal "return light damage" of the reflected laser, leading to poor equipment stability and high maintenance costs, becoming a "hidden killer" of production line yield.

The Guanghui anti high reflectivity laser technology physically reconstructs the entire chain of laser generation, transmission, and action. When processing high reflectivity materials such as copper and gold, it can effectively suppress more than 99% of harmful return light, achieving ultra precision cutting with smooth cross sections and no broken edges. In semiconductor packaging and substrate processing of third-generation semiconductors such as SiC and GaN, the application of this technology has revolutionized the efficiency and yield of key processes such as cutting copper foil on silicon substrates, greatly improving chip strength and yield. For new materials such as flexible circuit boards (FPCs), their "cold working" characteristics can perfectly avoid thermal damage.

Aerospace: Conquering the 'Splash'stubborn disease

Whether it is aircraft skin, rocket engine nozzles, or brake discs, their materials are prone to problems such as slag splashing, microcracks, delamination, and excessive heat affected zone (HAZ) during traditional or ordinary laser cutting/welding. These issues are directly related to the ultimate reliability and safety of the equipment.

For difficult to weld materials such as titanium alloys and nickel based high-temperature alloys, high-intensity laser deep welding can achieve high-quality connections with a joint strength coefficient exceeding 90%, and the fatigue life of the weld seam far exceeds traditional methods. ABR technology ensures efficient and high-quality welding of aluminum alloy skins, conduits, and other components, aiding in the lightweighting of aircraft.

Biopharmaceuticals: Mastering the Art of Precision

Biomedical devices, such as vascular stents, heart valves, and surgical robot components, require precision and biocompatibility at the microscale. Medical grade stainless steel, nickel titanium alloy, degradable magnesium alloy and other materials require cutting, punching, and welding on a scale similar to the diameter of a human hair. Any burrs, thermal deterioration, or changes in micro area composition can pose a risk of thrombosis or affect the degradation cycle, which can be life-threatening.

High brightness fiber laser technology is the key to achieving "precision manufacturing". By using 793nm pumping technology, a perfect beam quality close to the diffraction limit (M ²<1.1) is obtained, which concentrates the laser energy to the minimum theoretical spot and avoids the destruction of material biological properties with minimal thermal input. Micro scale cutting accuracy and weld width can be used to process complex network structures of capillary stents; Laser cleaning technology can provide sterile and non-destructive surface pretreatment for precision medical devices.

Low altitude economy: outlining "lightness"architecture

From precision cutting and drilling of carbon fiber composite materials for unmanned aerial vehicles to automated welding of lightweight alloy structures for eVTOL (electric vertical takeoff and landing aircraft), the Guanghui laser solution significantly improves structural efficiency and production automation level while ensuring ultimate reliability and safety.
