Zinc Coated Steel Deep Drawing Stamping Housing Parts For Car Wheel: Key Components to Protect Driving Safety

1. Product function and process characteristics
Zinc Coated Steel Deep Drawing Stamping Housing Parts For Car Wheel is an indispensable key component in automobile manufacturing, mainly used in wheel hub covers, brake system protective covers and other parts. This type of parts is formed by deep drawing and stamping process using galvanized steel plates, and has three core advantages: the galvanized layer has good corrosion resistance, and the salt spray test can last up to 720 hours without rusting, extending the service life of the wheel system; the deep drawing process causes the material to produce work hardening, and the tensile strength is increased by 30%-50%, while maintaining good ductility; precision stamping ensures that the part size tolerance is controlled within the standard range to ensure compatibility with the wheel hub.

2. Analysis of applicable models and user groups
Zinc Coated Steel Deep Drawing Stamping Housing Parts For Car Wheel is mainly suitable for three types of models: economical family cars mostly use cost-optimized standard models; SUVs and off-road vehicles require thickened design and special anti-corrosion treatment; new energy electric vehicles need customized development to adapt to unique shapes due to the large wheel size. From the user's perspective, four types of car owners should pay special attention to the use status of such parts: car owners who often drive along the coast or in areas where snow melting agents are used, high salinity environments accelerate corrosion; car owners who are keen on modification need to match special housings when replacing wheels; frequent off-road drivers are prone to surface damage caused by stone hitting; and users who buy second-hand cars for more than 5 years need to check whether there is hidden rust on the old car housing.

3. Maintenance Guide
Proper maintenance can extend the service life of galvanized steel shell parts. It is recommended to establish a three-level maintenance system: on a daily basis, simply check the surface for obvious dents or scratches every week, and use a high-pressure water gun to wash the accumulated sand inside the wheel hub every month; regular maintenance should be performed every 10,000 kilometers or 6 months, dismantle the shell to thoroughly clean the inside and outside, check whether all fixing buckles are intact, and apply special anti-rust grease if necessary; deep maintenance is recommended before the rainy season every year, including using pH-neutral wheel hub cleaner to remove stubborn stains and apply galvanized repair paint to areas with slight scratches. Avoid using detergents containing chlorides or strong acids and alkalis when cleaning, as these substances will damage the galvanized layer. In winter, pay attention to clearing snow from the wheel hub in time to prevent the snow melting agent from contacting the metal surface for a long time. For users of modified vehicles, the fit of the new shell should be confirmed after replacing the wheel hub. Mismatched installation will cause abnormal vibration and loose screws.

4. Common problems and solutions
Five typical problems may be encountered during use: abnormal noise often comes from deformation of the shell or breakage of the fixing buckle, which is manifested as a regular "click" sound at speeds above 60km/h, and it is necessary to stop and check immediately; high-speed vibration is usually caused by imbalance of the shell dynamic balance, especially after changing the tire, which requires professional dynamic balance correction; local rust often occurs at the edge of the drain hole or deep in the scratch, which can be treated with a zinc-based repair pen in the early stage, and large-area rust requires overall replacement; installation difficulties are common in low temperature environments in winter, and plastic buckles become brittle. It is recommended to operate after the indoor temperature rises. The dangerous situation is that the shell breaks and rubs against the tire, which can cause a sudden tire blowout, so any cracks should be replaced immediately. The original factory-specified tools ( must be used for maintenance to avoid secondary damage caused by rough operation. As the age of the vehicle increases, it is recommended to use an endoscope to check the status of the hidden parts inside the shell during each maintenance for vehicles over 7 years old, which is an area that cannot be reached by conventional visual inspection.
