For cars, wheels and tires are parts that directly touch the ground. If the wheel and tire are compared to the upper and the sole, it is suitable. In practical use, the wheel not only plays a huge supporting role for the car, but also has a crucial impact on the appearance of the entire car. If the shoes are dirty, they can be washed. If the wheels are dirty and damaged, they need to be repaired also.
For most people, when the wheel needs to be refurbished and repaired, these troubles are usually thrown to professional 4S shops and related repair shops.
Alloy wheels occupy more than 90% of the wheel market due to their features like low cost, light weight, durable and easy to repair.
The alloy wheel is mostly made of aluminum as the basic material, and is appropriately added with metal elements such as manganese, magnesium and titanium, and can be divided into two processes of casting and forging. The casting process of the casting wheel only needs to pour the hot aluminum water into the mold, demoulding after cooling and forming, and the body of the wheel can be polished and sprayed. This production process is simple and the production speed is fast, but the disadvantage is that the metal molecular structure is Loose, easily damaged by large impacts. At present, some the original wheel on car are made from this process.
Forging is a lightweight wheel that is currently keen on the modification industry. The manufacturing process is complicated. It is necessary to use a high pressure (mostly several thousand tons of pressure) to press a heated alloy into a coarse embryo (formation), and then use CNC Lathe to detail carving as secondary processing, resulting in a lighter and tougher wheel. Wheels using this process are three times more powerful than conventional alloy wheels, but are lighter in weight and have a richer look.
And what we usually call wheel repair refers to the repair of forged alloy wheels.
However, what you need to know is that some wheels are not routinely repaired.
1. Steel wheel. It has high hardness, easy to break and rust, and it is a phase-out product.
2. Cast alloy wheel, low version of forged alloy wheel, easy to break and deform.
3. The carbon-fiber composite wheel has high cost, easy to damage its original stability after repaired.
4. Magnesium alloy wheels have low service life.
Of course, the above types of wheels are rare in the daily use of cars, and ordinary people basically have no chance to see them.
In summary, a wheel repair lathe can repair more than 90% of the wheels on the market. It can be said that the one-time investment has a broad market. For those shop owners who don't have a dedicated wheel repair machine, what are you waiting for?
