Explore our highly-acclaimed mechanical solutions exported globally, manufactured under strict ISO9001 compliance standards.
A comprehensive study on dynamic safety, thermal performance parameters, and global manufacturing standards.
In the modern automotive and motorcycle manufacturing ecosystem, the brake disc has progressed from a simple cast iron rotational friction target into an engineered thermodynamic element. As kinetic energy is converted into thermal energy, modern brake rotors routinely experience temperatures exceeding 700°C under severe operational stresses. Ensuring the structural integrity of the disc requires rigorous attention to carbon equivalent ratios, microstructure configurations, and precise gray cast iron chemistry.
VETOR GROUP addresses these core physical challenges by utilizing optimized gray iron formulations (GG25/HT250 standards). Our high-carbon brake discs are enriched with copper, chromium, and molybdenum alloys, enhancing thermal conductivity and thermal fatigue resistance. This ensures uniform temperature distribution, prevents localized hot spotting, and significantly minimizes thermal distortion, structural cracking, and DTV (Disc Thickness Variation).
Anticipating the technological demands of future transport, electric powertrains, and strict emission regulations.
Reducing unsprung mass is crucial for boosting vehicle range and agility. Hybrid brake discs, combining a lightweight aluminum hat with a cast-iron friction ring, cut weight by up to 30%, lowering overall energy consumption.
With electric vehicles using regenerative braking, mechanical friction brakes can sit unused for longer periods, leaving them prone to corrosion. Zinc-flake, Geomet, and nitrocarburizing coatings provide corrosion protection and maintain aesthetic appeal.
Future environmental standards will regulate particulate emissions from brakes. Hard coating techniques, such as High-Velocity Oxygen Fuel (HVOF) thermal spray and laser cladding (e.g., tungsten carbide), significantly reduce brake dust wear by up to 90%.
Established in 2005, delivering premium mechanical and automotive components globally.
VETOR GROUP was founded in 2005. We are a comprehensive foreign trade group specializing in import and export operations. Our company is located in Cixi City, a vibrant economic hub in China, on the bank of the fertile and scenic Hangzhou Bay. Thanks to our strategic location, we enjoy close proximity to two of China's largest ports—Shanghai Port and Ningbo Port—as well as easy access to Hangzhou Xiaoshan International Airport and Ningbo Lishe International Airport, both only about a 90-minute drive away. This offers exceptionally convenient transportation and logistics advantages.
We specialize in supplying a wide range of products including Motorcycle Parts, Auto Parts, ATVs, Dirt Bikes, Bicycles, and Related Components. Committed to exceeding customer expectations, we provide diverse, high-quality products and services to help our clients thrive in a highly competitive global market. All our products are exported worldwide, and our operations are certified to the ISO9001 international standard.
In addition to our extensive automotive parts, our in-house manufacturing facility specializes in the production of deep groove ball bearings and EMQ grade bearings, with inner ring dimensions ranging from 6mm to 90mm. We place strong emphasis on brand development, and our VETOR brand bearings are known for their:
How we address the complex quality, logistics, and legal constraints of procurement managers worldwide.

Technical answers to common inquiries from automotive engineers, quality managers, and B2B procurement professionals.
We use HT250 / GG25 grey cast iron with a high carbon equivalent (3.2% - 3.6%). This composition is selected to balance mechanical strength, thermal conductivity, and damping characteristics, minimizing brake squeal and heat checking.
Our CNC double-disc grinding processes machine both friction faces simultaneously. This ensures parallelism, keeping DTV below 0.008mm and lateral runout within a 0.013mm limit, which helps reduce brake pedal pulsation.
We offer Geomet (zinc flake), phosphate, electrophoretic coating, and nitrocarburizing. Geomet is recommended for electric vehicles due to its long-lasting corrosion resistance when mechanical brakes are used less frequently.
Our standard MOQ is 1,000 units for standard designs. Depending on customization, production and shipment prep ranges from 7 to 20 days.
Yes, our manufacturing complies with ISO9001 standards. We also coordinate with testing authorities to provide ECE R90 certifications for European aftermarket applications, ensuring legal compliance.
