In high-end manufacturing fields such as new energy vehicles, data center liquid cooling, and industrial thermal management, the manifold, as the "heart" of the fluid distribution system, directly determines the stability, safety, and service life of the entire system through its welding quality. As industry requirements for sealing, pressure resistance, and thermal stability become increasingly stringent, traditional welding processes are no longer sufficient to meet high-standard production demands. With over a decade of experience in precision laser welding technology, Fly Laser focuses on the laser welding of manifolds, providing customized equipment, intelligent processes, and end-to-end solutions to create a zero-defect, high-efficiency, and highly reliable welding ecosystem for its clients. This helps companies break through precision manufacturing bottlenecks and seize the high ground in the high-end market.
I. Industry Pain Points: The Triple Challenges of Separate Manifold Welding
Separate manifolds are mostly thin-walled precision structures made of stainless steel, aluminum alloy, copper alloy, etc., featuring multi-channel, multi-interface, and complex flow channel designs. The welding process faces three core challenges:
Strict Sealing Requirements: Liquid cooling and thermal management systems require leakage rates ≤10⁻⁷ Pa·m³/s. Traditional argon arc welding and brazing are prone to micro-cracks, porosity, inclusions, and other defects, resulting in leakage rates as high as 10⁻⁵-10⁻⁴ Pa·m³/s, posing serious safety hazards. There have been industry cases where welding defects led to equipment damage, production stoppages, and single-instance losses exceeding 2 million RMB.
Difficulty in Controlling Thermal Deformation: Thin-walled workpieces (0.3-2mm) are extremely sensitive to heat input. Traditional processes result in large heat-affected zones, easily leading to manifold deformation, flow channel blockage, and exceeding dimensional accuracy standards. Subsequent calibration and grinding processes increase production costs by more than 30%, and batch consistency cannot be guaranteed. Poor Adaptability to Complex Structures
Complex structures such as multi-channel, irregularly shaped interfaces, and 360° circumferential welding make it difficult for traditional equipment to achieve precise trajectory tracking, resulting in numerous welding dead spots, low yield rates, and an inability to meet the demands of large-scale automated production.
II. Technological Breakthrough: The Core Advantages of Fly Laser Welding Machines
Addressing the pain points of manifold welding, Fly Laser has developed specialized laser welding equipment that integrates a high-precision optical system, an intelligent control system, and customized chemical fixtures, forming five core technological advantages: High Precision and Low Heat Input, Eliminating Deformation and Leakage
Utilizing a single-module continuous fiber laser with a power range of 250W-2500W, a focused spot diameter of 0.1-0.3mm, and an energy density exceeding 10⁶W/cm², it achieves micron-level precise heating, reducing the heat-affected zone to 1/5 of that of traditional processes. Equipped with Wobble oscillating welding technology, the weld pool is actively stirred via a Z-shaped scanning trajectory, achieving precise control over weld width from 0.5-3mm, a 30% increase in penetration depth, a dense weld structure free of porosity and spatter, and a burst pressure reaching 2.5 times the design value, with a 100% pass rate in airtightness testing.
Multi-axis linkage intelligent system, adaptable to complex structures
Equipped with a 4-6 axis high-precision servo linkage platform, with a repeatability accuracy of ±0.02mm, it supports any complex trajectory including straight lines, arcs, spirals, and 360° circumferential welding. It can achieve simultaneous welding of multiple interfaces and weld seams in manifolds, with a maximum welding speed of 18 meters per minute. An integrated AI vision positioning system automatically identifies workpiece deviations and corrects the welding path in real time, eliminating the need for repeated manual adjustments. The yield rate for complex manifold welding remains consistently above 99.5%.
Customized tooling solutions ensure stable batch production.
Modular, adaptive tooling fixtures are designed specifically for the structural characteristics of dispensing manifolds. These fixtures integrate dynamic clamping, localized heat dissipation, and pre-cleaning functions, precisely controlling workpiece gaps to ≤0.05mm. Combined with multi-stage layered airflow protection technology, they prevent welding oxidation and inhibit slag formation. The tooling supports rapid changeover, allowing switching between different manifold specifications within 10 minutes, adapting to the needs of multi-variety, small-batch, and large-scale continuous production.
Intelligent process database enables efficient production with immediate adjustment.
The database contains over 500 specific welding parameters for dispensing manifolds, covering mainstream materials such as stainless steel 304/316, aluminum alloy 6061/5052, and copper alloys. Optimized solutions are preset for different thicknesses and structures, allowing operators to achieve stable welding with a single click. The equipment supports remote monitoring, data storage, and fault diagnosis, recording welding current, power, speed, and other parameters in real time, meeting the traceability requirements of factory audits in industries such as automotive and data centers.
Green and Environmentally Friendly, Cost Reduction and Efficiency Improvement
The welding process is smokeless and radiation-free, with a dust removal system meeting environmental standards; no welding materials or preheating are required, and energy consumption is only 40% of traditional processes; no grinding or correction is needed after welding, reducing the single-piece production cycle from 45 seconds to 28 seconds, saving over 2 million yuan annually in labor and material costs.
