The production process of aluminum rims

2015-02-04

When faced with making a decision about choosing aluminum rims, we often encounter a considerable problem. The wide assortment of stores offering this type of products makes us constern? we do not know whether to be guided only by visual issues, we wonder why similar at first glance models differ drastically in price, we do not know which will be more reliable and will last with us for a long time. Willing to help you understand the functioning of the interesting world of aluminum rims, we will present various methods of producing popular allus alloys , paying particular attention to the impact of these methods on the functionality of finished products.

Various methods of producing aluminum rims

When visiting any rim shop, the first thing that strikes us is the wealth of choice. They differ not only in the size and color of the finish, they delight or scare you with the price you have to pay for them. Where do these great differences come from? There is only one answer? the method of production is to blame.

The most popular method of obtaining allus is the low-pressure method . It is based on the action of air under pressure on aluminum which is in liquid form during casting. In the next step, after cooling down, specialists check the rim for imperfections that may affect its durability. In the event of a positive result of this test, further inspection of the product takes place, this time from the inside using an X-ray machine. If there are no objections, the rim is heated at high temperature and allowed to cool slowly. This process is intended to ensure its higher durability and strength. After completion of the activities, mounting holes are drilled and varnishing takes place.

Another method of obtaining rims is called gravity . It is the simplest and cheapest and? how easy to guess? the least effective . Unfortunately, when using it, X-rays are not used to find hidden defects. There is also no use of air in the formation of the product, and is based, as the name suggests, on the force of gravity. This is how aluminum goes to the die where it is formed.

People who are even a little interested in the automotive industry know the method of forging rims . Extremely popular, considered the best, in fact it is not, especially for ordinary road users. Of course, thanks to it, you can get extremely durable rims, but it is connected with a high price , which is not commensurate with the possibilities. What is the creation process in this case? Aluminum is heated to high temperature and then subjected to enormous pressures of a precise press, which compacts and forms the raw material until the desired form is obtained. Such a rim, as mentioned before, is characterized by extraordinary durability, thanks to the high density of the material obtained by tamping.

There is one more way to produce rims? rolling . The resulting rim in terms of strength will be as solid as for forging and, unfortunately, similarly expensive. For this method, the preparation process is as follows: special rolls compact the material until it reaches the desired shape. This affects the density of the rim, making it extremely durable.

Which method of obtaining rims will be the best?

Unfortunately, we cannot answer this question unequivocally. When visiting a rim shop and wanting to make the best decision, we need to know what we are looking for. If the rim is to be above-average strength, we should opt for forging or rolling rims, but if we want to choose wisely, it is best to look at the rims made using the low-pressure method. Doesn't that mean compromise, though? the products obtained in this way are also solid and are perfect for everyday driving.
