SKD&CKD

In the intricate landscape of automotive manufacturing, SKD (Semi-Knocked-Down) and CKD (Completely-Knocked-Down) products serve as the bedrock for constructing a vehicle’s core power and critical systems. As an enterprise dedicated to the automotive sector, we leverage advanced technology and exquisite craftsmanship to produce a wide range of automotive SKD & CKD products, including Motor Iron Core, Windings, Rotor Assembly, and more. We provide comprehensive support—from key components to system integration—for automotive manufacturers, empowering them to create high-performance and high-quality vehicles.

Precision Manufacturing: Forging the Quality of Core Components

We deeply understand that core components play a decisive role in a vehicle’s performance, which is why we pursue extreme precision in the manufacturing of SKD & CKD products.

Motor Iron Core，Take the Motor Iron Core as an example. We employ high-precision stamping technology, rigorously controlling dimensional tolerances and geometric tolerances. Each Rotor Lamination is stamped through the collaborative operation of precision molds and intelligent equipment, ensuring they interlock neatly like precision building blocks. This precision maintains a smooth magnetic circuit inside the motor, akin to creating an “unobstructed channel” for electric current. A smooth magnetic circuit is the foundational logic for the motor’s efficient operation—it reduces magnetic energy loss, enabling more efficient conversion of electrical energy into mechanical energy. This strengthens the foundation for the vehicle’s power output, ensuring stable and robust performance even under complex working conditions.

Windings，Relying on advanced winding and coil-insertion technologies, we achieve tight and regular arrangements of Enameled Wire. Our winding equipment precisely controls the tension and winding trajectory of the copper wires, “weaving an energy network” for the motor to ensure every coil is positioned with precision. During the coil-insertion process, intelligent tooling and techniques are used to accurately embed the wound coils into the stator slots, ensuring consistent coil shape and spacing. Such windings significantly enhance the motor’s electrical energy conversion efficiency, reduce energy loss during transmission, and increase output power—making vehicle acceleration and hill-climbing more powerful. Additionally, they reduce motor heat generation and extend service life.

Rotor Assembly，The manufacturing of Rotor Assembly is equally meticulous. The Shaft undergoes precision grinding and polishing to achieve micron-level dimensional accuracy, ensuring perfect compatibility with components such as Bearings and rotor cores. The rotor core uses high-precision lamination and welding processes to tightly bond each Rotor Lamination, maintaining structural stability during high-speed rotation. Dynamic balance testing is a critical step: professional equipment detects unbalance in the rotor, which is then optimized through weight removal or addition. This minimizes vibration and noise during high-speed rotation. A stable Rotor Assembly ensures reliable operation of the vehicle’s power system, delivering smooth and quiet power transmission whether navigating frequent stops in urban traffic or sustaining high-speed driving—enhancing the overall driving experience.

Bearings, Despite their small size, Bearings play a vital role. We offer two types: Ball Bearings and Bushing (Oiled Bushings). Ball Bearings, crafted with precision machining for high-speed scenarios (e.g., gearboxes), feature strict tolerance control on inner/outer diameters and use wear-resistant alloys to minimize friction and ensure smooth rotation. Bushing, with self-lubricating porous structures (e.g., copper/iron-based), excel in low-speed, steady-load applications (e.g., seat adjusters), reducing friction via embedded oil while simplifying maintenance. Both types reduce hard friction, cushion vibrations, and extend component life, ensuring stable steering, suspension, and overall vehicle durability.

Every core component, from design to manufacturing, undergoes our relentless pursuit of “precision.” We understand that these hidden “small details” within the vehicle ultimately converge into a “big experience” of overall performance and quality, solidifying the foundation for automotive manufacturing.

Diverse Adaptability: Meeting Varied Manufacturing Needs

Automotive manufacturing encompasses diverse scenarios, and our SKD & CKD products offer broad adaptability. Whether automotive OEMs engage in large-scale standardized production (using our CKD products to flexibly assemble vehicles according to their production line characteristics and technical requirements, with full-process quality control over Motors, Transmission Components, and Interior Parts) or automotive modification enterprises and emerging automakers pursue personalized customization (using our SKD products for flexible combinations of key components like Rotor Assembly, Bearings, and Gearbox) to quickly respond to customized designs, we enable the creation of vehicles with unique performance and appearance. Our solutions adapt to different technical routes, from traditional fuel vehicles to new energy vehicles.

Collaborative Innovation: Driving Automotive Technology Upgrades

In an era of accelerating automotive technology iteration, we actively collaborate with automotive manufacturers on innovation. Focused on the high-range and high-power demands of new energy vehicles, we develop new Motor Iron Core materials and structures, optimize Windings heat dissipation design, and enhance motor efficiency and range. For the high-precision control requirements of intelligent driving, we refine the processes of SKD & CKD products for components like Sensors, Actuators, and Connectors to ensure precise signal transmission and command execution. By deeply participating in the technological R&D of automotive manufacturers, our SKD & CKD products have become a vital force driving the electrification and intelligentization of the automotive industry.

Rigorous Quality Control: Ensuring Reliable Vehicle Operation

Quality is the baseline for automotive safety and performance. We have established a full-process quality control system. Raw Material Procurement, Strictly select Enameled Wire, steel, Magnets, and insulating materials to ensure they meet high automotive industry standards. Production Process, Combine real-time online inspection (e.g., automated dimensional checks for Rotor Laminations and Shafts) with multi-stage quality checks to promptly identify and eliminate defective products. Pre-Delivery Testing, Simulate full-life-cycle working conditions, including salt spray, thermal cycling, and load testing, to verify reliability of components like Bearings, Thermal Protector, and Waterproof Vent Membrane in extreme environments. Every set of SKD & CKD products—from individual Carbon Brush to complete Gearbox—undergoes layers of scrutiny to build a solid quality foundation for reliable vehicle operation.

From the “heart” of the vehicle—the Motor—to critical components like Rotor Assembly and Bearings, our automotive SKD & CKD products are deeply integrated into every link of automotive manufacturing. Choosing our products means infusing vehicles with genes of precision, reliability, and innovation. We join hands with automotive manufacturing partners to co-create a new future of high-quality development in the automotive industry, ensuring every vehicle can drive forward with exceptional performance.
