In the field of intelligent energy, breakthrough performance starts on the factory floor. At KSTAR's Huizhou manufacturing base, cutting-edge hardware engineering meets intelligent automation—creating the backbone for next-generation energy solutions.

The Huizhou Sheet Metal Factory serves as the precision core of this ecosystem, manufacturing high-performance structural components for KSTAR's UPS systems, PV inverters, and energy storage PCS. From R&D to final delivery, every step is engineered for accuracy, consistency, and scale.

01 | Engineering Excellence Through Four Core Processes

Operating five specialized workshops—spring forming, stamping, welding, coating, and assembly. The factory maintains complete control over component quality from raw material to finished product.

1.         Precision Stamping & Bending

High-precision stamping maintains tolerances within ±0.1 mm—roughly the thickness of a human hair. Combined with high-tonnage processing capacity, this enables rapid fulfillment of large-scale orders without compromising quality.

2.         Automated Robotic Welding

Robotic welding systems achieve 99.9% consistency, delivering superior structural strength for server racks, megawatt UPS systems, and liquid-cooling solutions. These welds support critical standards including Level-9 seismic resistance.

3.         Advanced Coating Technology

Fully automated coating lines deliver exceptional durability: IP65 weatherproofing for outdoor PV inverters and C5-level anti-corrosion protection for energy storage systems in harsh environments.

4.         End-to-End Quality Assurance

3D scanning and continuous monitoring inspect every component, while vertically integrated supply chains ensure both quality consistency and agile delivery.

02 | Intelligence in Motion: The Digital Factory Advantage

Data drives everything at Huizhou. The factory integrates production automation, equipment intelligence, and management digitalization into a transparent, traceable ecosystem.

1.       Real-Time Visibility

Key equipment interfaces directly with MES, providing real-time insights into production status and efficiency—boosting productivity and first-pass yield rates.

2.       Digital Twin Technology

Physical production lines are mirrored virtually, enabling panoramic visualization and precise process control before execution.

3.       Integrated Systems

MES, SRM, and WMS connect data flows across procurement, production, and logistics. Delivering transparency, accuracy, and intelligent decision-making that continuously improves efficiency.

03 | Manufacturing the Future of Smart Energy

As a key capability pillar of the Huizhou manufacturing base, the Huizhou Sheet Metal Factory delivers precision manufacturing and digitalized operations that support KSTAR's vertical integration strategy from critical components to complete systems. Closely aligned with data centers and new energy applications, it strengthens every business line with solid manufacturing fundamentals.

Looking ahead, KSTAR will strengthen its high-end manufacturing capabilities by refining processes with digital-era craftsmanship and driving industrial upgrades through intelligent innovation. With the Huizhou manufacturing base and key facilities like the sheet metal factory, KSTAR is building a robust smart manufacturing foundation to support high-quality development in the smart energy industry and power the journey toward the future.
