OUR FACTORY
Founded in 2007, Guangzhou Zhongpeng Auto Parts Co., Limited. is a company specializing in R&D, production and sales of forged wheel spacers, wheel bolts and lug nuts. We have independent factory with more than 10 R&D personnel and more than 30 other employees. So far, BONOSS has registered patents in many countries and regions and has obtained more than 66 SGS TÜV test report certifications.
Material Testing Department
Operating wheel spacer material testing can help us meet or exceed international quality standards and earn the trust of both new and existing clients. BONOSS laboratories can perform professional and repeatable wheel spacer material testing to meet clients’ exact specifications. Only materials with good quality are used to manufacture BONOSS wheel spacers.
Machining Department
The BONOSS factory uses the advance CNC machines to manufacture wheel spacers. Vertical lathes use gravity to achieve superior concentricity and runout while mills with high rigidity and spindle speeds reduce cycle time and produce smoother surface finishes. So far, the BONOSS Factory has achieved precision tolerance control within 0.02mm.
Finishing Department
BONOSS’s manufacturing facilities include a wide array of finishing options, such as Hard anodizing, Electrophoresis, and Dacromet coating. By bringing every part of wheel spacer production in-house, BONOSS has full control of the finished product, guaranteeing that each wheel spacer that ships is of exceptional quality and precision.
DESIGN
BONOSS always insisted on independent design and continuous optimization to design automobile wheel accessories with stronger performance, more functions and better customer experience. More than 1,800 product upgrade drawings allow us to provide the best products for the latest car models. So far, BONOSS owns many patents, for example, the global registered active cooling technique.
Design Process
Quality, safety, and performance are BONOSS’s end goal. Our talented designers aim to design the best products to meet customer needs and fill the market gap. So far, BONOSS has provided OEM, ODM, customize services to customers in over 100 countries and regions.
Perfect Fitment
BONOSS has invested a hefty sum in designing and testing the products. This makes BONOSS products safer and more reliable. A seamless fitment would be impossible without the utmost precision throughout the entire manufacturing process.
Optimized Vehicle Aesthetics
Every car model has different parameters and clearances and every car owner has various aesthetic ideals. Our 10,000+ product examples are here to help you select the best wheel spacer combination, maximizing the wheel style and perfecting overall fit.
Testing
To meet and exceed these standards, BONOSS invests a large amount of time in research design and safety testing. The resulting products will be subject to all classic performance tests such as tensile strength, yield strength, proof load, hardness, neutral salt spray, and so on.
Measurements
Over 1,000+ measurements are collected from cars, including the bolt pattern (PCD), center bore (CB), wheel bolt length, and more, to ensure a perfect fit. Take the wheel spacers as an example, the PCD and CB dimensions are machined specifically to fit specific vehicles, reducing the chance of wheel vibration.
100% Fit, No Gap
BONOSS engineers tailor products for each exclusive car. This ensures that your vehicle will attain its best wheel style and performance. Every BONOSS wheel spacer is engineered to be superior to provide car enthusiasts with higher quality, better performance, and safety.
Material
Manufacturing the best wheel spacers begins with nothing but the finest raw materials. BONOSS forged wheel spacers are made of aerospace-grade 6061-T6 and 7075-T6 aluminum alloys.
Heat Treat
The “T6” heat-treated provide additional integrity. Therefore, aluminum alloys are sometimes stronger than the raw materials used by the world’s top wheel manufacturers.
Super Forging Process
BONOSS forged wheel spacers are manufactured from a solid piece of metal called billets. The billet undergoes continuous intense pressure to be formed. Due to the stress cycle and process of deformation, BONOSS forged wheel spacers become harder and stronger.
Inspections
The warehouse personnel will carefully check each raw material. Only the high-quality materials that pass the tests will be used. All the tests are performed in accordance with international standards. Moreover, we insist on specific materials for specific products, never mix with other inferior materials.
CNC 0.02mm Machining
Precision is one of the most important indicators of manufacturing wheel spacers. In the producing phase, the CNC machines remove as little as 0.02mm of material per pass to achieve the utmost precision.
Initial Completion
Once the wheel spacer face design is complete, we will operate an additional CNC milling to shave glitches wherever possible.
The higher the accuracy, the better the surface quality, and the higher the reliability.
Hard Anodizing
Additionally, BONOSS forged wheel spacers applied advanced hard anodizing coating technology. The process provides the surface with better abrasion resistance, flame resistance, and smoother and harder finish protection than regular paint or metal plating.
Quality Control
High precision requires continuous proper quality control, which is why BONOSS meticulously inspects each wheel spacer during every step of the process. BONOSS machinists perform careful inspections on every wheel spacer to confirm that the spacer is within tolerance.
