HKAA provides custom automotive CNC machining services for global automotive manufacturers, Tier 1 suppliers and engineering companies. With advanced CNC milling, turning and 5-axis machining capabilities, we manufacture precision automotive components including aluminum housings, brackets, shafts, transmission parts and EV components with tight tolerances and consistent quality.

Automotive carbon fiber parts CNC machining provides high-strength, lightweight, and precision-engineered components for electric vehicles, racing cars, luxury automobiles, and aftermarket modifications. With tolerances as tight as ±0.01mm, our CNC carbon fiber machining service delivers superior dimensional accuracy, flawless edge quality, and exceptional durability for demanding automotive applications.

For patio doors, garden gates, or modern interior doors, our aluminum bolts provide peace of mind. They withstand the elements outdoors while maintaining their sleek look indoors, offering reliable security without compromising on style.

Our stainless steel universal joints provide reliable angular power transmission while offering excellent corrosion resistance. Perfect for applications requiring flexibility and durability in harsh environments.

Our stainless steel round head screws feature a smooth, domed head design that provides a finished appearance while minimizing snagging. Made from grade 304 or 316 stainless steel, these screws offer excellent corrosion resistance for indoor and outdoor applications. Ideal for furniture, machinery, and marine equipment.

Our high-precision pulley kits are engineered for critical motion control applications requiring accurate and synchronous power transmission. These kits typically include precisely matched timing pulleys and belts, designed to eliminate slip and maintain perfect synchronization between shafts. Manufactured to exacting tolerances from materials such as aluminum, steel, or plastics, our pulley kits ensure minimal vibration, reduced noise, and long-term reliability. They are ideal for use in robotics, CNC machinery, medical devices, and automated equipment where positioning accuracy is paramount.

Our CNC-machined aluminum timing pulleys ensure accurate power transmission in synchronous drive applications. Featuring precise tooth profiles (GT2, GT3, HTD, MXL) and lightweight construction, these pulleys reduce rotational inertia while maintaining strength. Ideal for robotics, CNC machines, and automotive timing systems.
