Hot bar head directly depends on its production skills

Haba head is a very common way to upgrade the automobile wheel hub, which is to change the aluminum alloy wheel hub or choose plus-sized wheel hub to improve the function, function and appearance of the automobile.

There are 1-piece, 2-piece and 3-piece aluminum alloy wheels. The 2-piece type is welded or nailed by 1 lnner piece and 1 outer piece. 3-piece aluminum wheel hub used casting parts. The 3-piece structure provides great flexibility for manufacture to make small batches.

Haba head directly depends on its production skills. Low pressure casting is a relatively basic method and also a relatively economical way. Low pressure casting is to cast molten metal into a mold and harden it; Back pressure casting is a relatively advanced casting method. It used a strong vacuum to suck metal into the mold, which is conducive to keeping constant temperature to remove impurities. There is no air hole in the casting, the density is uniform, and the strength is very high; The manufacturing process of High Back Pressure Die Casting(HCM) produces a nearly casting effect. The RX/RY (standard from 381 508mm) series aluminum wheels of the famous German manufacturer BBS are manufactured by the HCM method. Casting is more suitable for making wheels. The technique of pressing an aluminum ingot into the hub while it is hot under a pressure of 6000 tons. The strength of this wheel hub is 3 times that of the general aluminum wheel hub, and it is 20% lighter; Roll forging(also called die forging) is a kind of casting, casting the blank of one wheel hub in rolling. Rolling forged wheel hub can greatly reduce the thickness of data while insisting on sufficient strength. This is a relatively high place for wheel hub production. BBS RSH series is rolling forged.

Generally, the appearance of the wheel hub of the car model is less considered. It is a basic requirement that the Haba head heat  dispersion is good. The process basically uses baking varnish, that is, spraying first and then the electricity cost is relatively economical, and the color is beautiful, hold on for along time. Even if the vehicle is scrapped, the color of the wheel hub remains unchanged. Many Volkswagen model wheel hub surface treatment process is paint. Some fashionable and dynamic color wheels also use baking skills. This kind of wheel hub is affordable and has complete standards.

Although the electroplating silver and hydroplating wheels are bright and vivid in color, the persistence time is short, so the price is low. Pure galvanized wheel color lasts for a long time, high quality and high price. Medium and High cars, such as guangben and Audi, use pure galvanized wheel, which is more expensive.
