Forging can be divided into milling and mold forging.
1. Milling and forging
Through impact or pressure, the metal is deformed between the upper and lower pier (anchor seat), and the required block is obtained. However, due to the poor cake thickness and quenchtability during thermal treatment, the material performance of the final product may not reach the quality level of the forging process, and the forging streamlined will be cut off when processing forming, resulting in the final molding wheel product cannot truly lightweight.
2. Hot mold forging
Model forging can be divided into open mold forging and closed mold forging. The metal blank material obtains forg through pressure deformation in a forging module with a certain shape. Because the forging parts produced by this process are formed in the shape of the mold, the product wall thickness is uniform, and the performance after heat treatment is the best. Of course, the mold forging process needs to open a series of special molding molds, so its products are expensive.
The mold forging aluminum wheels can be designed to have thinner wheel spoke thickness and wheel thickness.
Through the above understanding, we know that forging wheels are currently the most advanced method for making aluminum wheels. The most prominent advantage is that high strength, higher safety, strong plasticity, light weight, good heat dissipation, and fuel saving; the disadvantage is that the price is slightly higher. The production cycle is longer. What are the advantages of forging wheels compared with the original cast wheel?
1. Durable and safer
Forging aluminum rings is 1-2 times higher than the cast aluminum ring, 4-5 times higher than the ordinary iron ring, so it is more strong and impactful. The toughness and fatigue intensity are also significantly better than the cast wheel. More sex.
2. Lightweight and more fuel -saving
Compared with the casting wheels of the same size, the weight can be about 20%lighter, while the wheels can reduce 1kg and increase 10 horsepower. In addition, lightweight also increases the reaction speed of the suspension, the reaction speed of the suspension system is faster, and it is more natural to deal with the potholes on the road surface.
3. Save fuel, good heat dissipation performance
According to Japan’s experiments, if a five -seater car lose 1kg, it can save about 20L of gasoline in one year. However, a research report published by the American Automotive Engineer Society pointed out that although forging wheels is more expensive than ordinary casting wheels, in the long run, cars can recover costs from 10,000 to 30,000 kilometers. In addition, the heat dissipation effect of the forging wheels can make the brake drums and tires difficult to age, extend the service life, and reduce the risk of explosion tires when driving on long -distance high -speed driving.
4. better control performance.
If the forging wheels are upgraded without affecting the steering and loading, if the width of the wheels is increased, the sensitivity of the vehicle acceleration, braking and cornering will be significantly improved. More briskly, the vehicle can be eased in entry and exit.
In summary, the performance and quality of the forging wheels are better than casting, which is of great significance to improving the performance of the vehicle, but the price is also higher than the casting. The corresponding choice should be made according to personal needs. It should be noted that when choosing forging wheels, you must pay attention to the wheel brand, otherwise you will buy some “forging” wheels of a niche brand, which is likely to cause the tragedy of “broken”, and the safety problem cannot be taken lightly.
