As a professional Auto Parts supplier, we understand that customers today are not only looking for affordable spare parts but also long-lasting reliability, precision manufacturing, and comprehensive support. Since our establishment, we have specialized in providing high-performance components such as the Weichai WP10H Engine and Bus Wagon Wheel Covers, both produced under strict quality control systems.
What makes us different from many other Auto Parts suppliers is our complete in-house production capability. From raw material processing to CNC machining, welding, polishing, assembly, and quality inspection, most procedures are performed within our own facilities. This ensures that our clients receive products with consistent quality and performance that meets international certifications such as CE, ISO9001, and GCC.

The Weichai WP10H Engine is one of the most advanced diesel engines in its class. As a top Auto Parts supplier, we put significant investment into advanced production technology to ensure every engine meets the high demands of commercial vehicles.
Casting and Forging: Engine blocks and critical components are cast with precision molds and treated with high-strength alloys for durability.
CNC Machining: Key parts such as crankshafts, pistons, and cylinder heads are processed with high-precision CNC machines to maintain dimensional accuracy.
Assembly Line: Semi-automated assembly lines ensure consistent fitting of parts, reducing human error and ensuring repeatable quality.
Performance Testing: Every WP10H Engine undergoes a complete power test, emission test, and durability test before leaving the factory.
Final Inspection: Our QC department performs multi-point checks covering torque, vibration, noise, and thermal balance.
As an experienced Auto Parts supplier, we know that reliability in engines is achieved only through strict process control. This is why our WP10H engines are trusted by transport fleets, construction firms, and public service providers worldwide.

Unlike many competitors, we emphasize stainless steel wheel covers because they offer better corrosion resistance and strength compared to conventional alloys. As a professional Auto Parts supplier, we manage the entire production cycle of wheel covers to ensure maximum durability.
Raw Material Cutting: High-grade stainless steel sheets are selected and cut to required dimensions.
Stamping & Forming: Hydraulic presses shape the covers into precise designs while maintaining structural integrity.
Welding & Polishing: Edges are welded seamlessly and polished to create a smooth, attractive finish.
Surface Treatment: Anti-fingerprint and anti-rust coatings are applied to withstand harsh environments.
Final Fitting Tests: Each wheel cover is mounted on a test rig to confirm dimensional accuracy and secure fitting.
By controlling every stage of production, we ensure that our stainless steel wheel covers stand out in quality, making us a preferred Auto Parts supplier for fleet operators and distributors.

As a reliable Auto Parts supplier, we know that every component must perform under challenging conditions. Our products are widely used in:
Public Transport Fleets: WP10H engines power buses across cities, while stainless steel wheel covers ensure durability and professional aesthetics.
Heavy-Duty Trucks: Engines provide strong torque for mining, construction, and long-haul logistics.
Special Purpose Vehicles: Fire trucks, sanitation vehicles, and emergency service vehicles rely on durable parts for uninterrupted operation.
Aftermarket Sales: Spare parts supplied globally to workshops and distributors who demand consistent quality.
These practical applications prove that working with a trusted Auto Parts supplier gives customers peace of mind when operating in demanding environments.
Every market has unique demands. As a leading Auto Parts supplier, we provide full OEM/ODM customization services to help clients differentiate their products.
Engine Customization: Adjusting emission standards, fuel compatibility, or power output according to regional requirements.
Wheel Cover Branding: Embossing company logos, adjusting sizes, and offering different finishes like polished, brushed, or chrome-plated.
Material Alternatives: Stainless steel for durability, or hybrid materials for cost-sensitive markets.
Packaging & Branding: OEM packaging that enhances product identity for distributors and resellers.
Our customization service is one of the reasons why global clients choose us as their trusted Auto Parts supplier.
