In an era of explosive growth in computational demand, the power density of CPUs continues to increase, placing unprecedented demands on thermal performance. As a mainstream cooling solution, the quality of the bond between the base and the heat pipes in a CPU air cooler directly determines the thermal conductivity and ultimate performance of the entire cooling module. In traditional manufacturing processes, "rolling" encapsulation and "facing" finishing are two separate, sequential steps. This discrete production model suffers from numerous drawbacks, including low production efficiency, large equipment footprint, and potential product quality instability caused by repeated positioning errors during transfers between different workstations.
Facing increasingly intense market competition and ever-stricter consumer demands for thermal performance, the traditional step-by-step processing method not only restricts capacity expansion but also makes it difficult to find the optimal balance between cost and quality. Consequently, the manufacturing industry urgently requires an innovative solution that can integrate key processes and achieve lean production.
The proposed "CPU Heatsink Rolling & Facing Integrated Machine" is born precisely to address this industry pain point. It highly integrates the two core processes that determine heatsink performance – rolling encapsulation and base facing – within a single automated equipment unit. Through a single clamping, it completes the precise rolling of the heatsink base to ensure tight contact with the heat pipes, immediately followed by a high-finish facing operation to ensure the base achieves an optimal micro-contact plane with the CPU integrated heat spreader.
This integrated innovation not only significantly reduces cycle time, equipment footprint, and manual intervention but also fundamentally eliminates the cumulative positioning errors inherent in process changes, markedly improving product yield and performance consistency. The successful implementation of this project will vigorously drive the CPU heatsink manufacturing industry towards higher efficiency, precision, and automation, providing downstream customers with core cooling components of superior performance and reliable quality.

► High Integration, Multiplied Efficiency
The equipment innovatively integrates three core processes—rolling, pressing, and facing—into a single workstation. This completely eliminates the material transfer and repeated positioning time required in traditional multi-machine operations, achieving seamless connectivity between processes, significantly reducing the cycle time per product, and delivering a leap in overall production efficiency.

► Precise Control, Exceptional Quality
The control system employs a FATEK 200K high-speed pulse main unit and expansion modules to provide precise and stable control commands for 5 servo motors. This design ensures highly consistent rolling tightness and facing finish, fundamentally guaranteeing the flatness and thermal conductivity of the heatsink base, thereby producing products of outstanding quality and stable performance.

► Compact Layout, Optimized Operations
The integrated design concept directly reduces the total number of equipment units and their footprint, optimizing workshop space utilization. Simultaneously, the fully automated process significantly reduces dependence on operators, effectively saving on labor allocation and management costs, achieving comprehensive optimization for customers in capital investment, space utilization, and operational efficiency.
