Production Equipment

Friction Stir Welding (FSW) is our core solid-state welding equipment for radiator and liquid cold plate manufacturing, designed for joining non-ferrous metals such as aluminum and copper alloys. Using frictional heat generated by the rotating tool, it forms defect-free, hermetically sealed welds with excellent thermal conductivity without melting the base material.
The equipment supports a wide range of thermal structure welding applications, including liquid cold plate channel sealing, cover-to-base joining, and extruded profile assembly. Compared with traditional fusion welding, it minimizes distortion, maintains high flatness control, reduces post-welding machining challenges, and improves weld strength and consistency. With CNC control and real-time parameter monitoring, it meets the high-reliability mass production requirements for new energy, industrial control, and consumer electronics thermal solutions.

Stamping is the core front-end process for aluminum radiator forming. Our stamping section is equipped with integrated automatic precision stamping units and supporting toolings, covering standardized processes including sheet uncoiling, leveling, precision stamping, bending, shaping and degreasing. It supports processing of common heat dissipation thin sheet materials such as aluminum alloy, galvalume and copper alloy. Adopting closed-loop servo-driven stamping system and high-precision cemented carbide dies, all equipment maintains stable repeated positioning accuracy within ±0.02mm, realizing integrated forming of radiator sheet metal components including cooling fins, base plates and fasteners. Compared with discrete stamping, automated lines minimize common defects such as burrs, sheet deformation and surface scratches, ensuring consistent flatness and dimensional tolerance of heat-conducting surfaces. All stamping machines are fitted with safety grating protection and production data acquisition modules to guarantee operational safety and process traceability. Equipped with auxiliary stations for die constant-temperature maintenance and ultrasonic cleaning, the workshop ensures finished stamped parts meet cleanliness and precision requirements for mass delivery of radiators for consumer electronics, new energy and industrial control industries.

The brazing furnace is a key thermal processing equipment in our radiator and liquid cold plate manufacturing process, primarily used for vacuum or controlled-atmosphere brazing of aluminum heat exchanger cores, fin-to-base assemblies, liquid cold plates and other multi-component structures. It adopts a high-precision zone temperature control system, enabling full-process curve control of heating, holding and cooling stages, ensuring uniform melting of brazing filler metal within the preset temperature range and sufficient wetting of the base material interfaces to form metallurgically bonded, defect-free joints.
Tailored for aluminum alloy heat dissipation parts, the furnace can maintain an oxygen-free or low-oxygen protective atmosphere, effectively suppressing oxidation of base materials and brazing fillers, eliminating common defects such as porosity, cold joints and intergranular corrosion. This ensures excellent hermeticity, thermal conductivity and long-term reliability of the welds. The equipment supports continuous mass production of various specifications, adapting to brazing requirements of radiator assemblies with different fin densities, channel structures and plate thickness combinations. Post-brazing workpiece deformation is well controlled, with dimensional accuracy and flatness meeting the assembly and thermal conductivity requirements of high-end heat dissipation products.
Compared with traditional fusion welding, brazing offers lower heat input and more uniform weld quality, making it particularly suitable for one-step integral forming of complex radiator cores. It significantly improves production efficiency and product consistency, serving as a core process guarantee for high-reliability thermal solutions such as new energy electronic control radiators, energy storage liquid cold plates and air conditioner heat exchangers.

The assembly line area is the back-end finishing and finished product integration station of the full radiator manufacturing process. It processes semi-finished products after friction stir welding, vacuum brazing and precision stamping, and completes standardized integrated assembly of heat dissipation components for industrial, new energy and consumer electronic industries. Equipped with closed-loop double-speed chain automatic conveying lines, pneumatic positioning toolings, numerical control torque tightening equipment, standard assembly workbenches and embedded online inspection units, it establishes an integrated streamlined operation system covering parts sorting, thermal interface material coating, fastener locking, accessory assembly and finished product re-inspection.
Adopting modular flexible station layout, the line can quickly replace positioning fixtures to support mixed production of diversified, small-batch and customized radiators including aluminum alloy heat sinks, embedded tube liquid cold plates and IGBT cooling modules without large-scale line modification. Standard station limit toolings and anti-collision turnover tools are adopted to avoid part collision and surface scratches, preserving the integrity of anodized aluminum surfaces. Three embedded quality control procedures including visual appearance inspection, torque data tracing and clearance dimension sampling are deployed on each station. All assembly torque, fitting tolerance and defect data are uploaded to the MES system for full-process traceability. Compared with traditional decentralized manual assembly, the automated line limits assembly tolerance within ±0.05mm, eliminates manual assembly deviations, improves structural coordination accuracy, and guarantees thermal contact performance and long-term structural stability, complying with stringent reliability standards for vehicle-mounted electronic control, energy storage and industrial server heat dissipation scenarios.
