What technology or materials are used in the silent wheels of Magnesium Alloy Baby Balance Bike to achieve the noiseless characteristics during driving?

In the selection of materials for the silent wheels of Magnesium Alloy Baby Balance Bike, rubber and polyurethane (PU) are two very popular choices. Rubber is known for its excellent elasticity and wear resistance. It can absorb the impact brought by the ground well, reduce the vibration transmitted to the body, and thus reduce noise. Polyurethane (PU) further improves the silent effect due to its good resilience, tear resistance and oil resistance. These materials not only ensure the good grip of the tire on a variety of ground surfaces, but also greatly reduce the noise generated when it contacts the ground.
The structural design of the silent wheel is also crucial. In order to minimize noise, the tread pattern of the tire is often carefully designed to reduce the noise generated when the air is compressed and released. At the same time, sound insulation layers or sound-absorbing materials such as foam or special fibers may be added to the inside of the tire to further isolate and absorb noise. In addition, the connection between the wheel hub and the tire is also optimized to ensure a close fit between the two and reduce the noise caused by looseness or friction.
The manufacturing process of the silent wheel is a high-precision and high-demand process. From mold design to production and processing, every link needs to be strictly controlled. The design of the mold needs to ensure that the roundness and balance of the tire are in the best state to avoid vibration and noise caused by tire imbalance. During the processing, advanced CNC machine tools and precision measuring equipment are used to ensure that the size and shape of each component meet the design requirements. At the same time, a strict quality control system runs through the entire production process to ensure that each silent wheel can meet the noise-free standard.
Although the silent wheels of baby balance cars usually do not have a complex lubrication system built in, some high-end products may use special technologies or lubricants to reduce friction and noise in key components such as bearings. These lubricants may have excellent anti-wear, anti-oxidation and noise reduction properties, and can maintain a stable lubrication effect during long-term use, thereby extending the service life of the product and improving the silent performance.
The silent wheels of Magnesium Alloy Baby Balance Bike have achieved noise-free characteristics during driving through innovations and optimizations in material selection, structural design, manufacturing process, and possible lubrication systems. Such a design not only provides a quieter and more comfortable riding environment for babies, but also reflects the manufacturer's high attention to product quality and user experience.
