Marking of aluminum rims

In this article you will learn about aluminum wheel marking, its advantages and applications and the different engraving techniques and machines.

Aluminum wheels are being used more and more in the automotive sector, as it allows a customization of the look of your vehicle giving it a higher end image or a totally different look.

Codes marked on vehicle tires

Many of you may have noticed some symbols marked on the rims of your cars. These are numbers and letters from which you can get information, such as the size of the wheel rim, its width…

We proceed to tell you the indicative markings of the rims of your car, in order to be able to interpret them correctly:

Let’s assume that your car’s tires have the following marking: 6j x 16h2 ET43

6j: the number indicates the rim width in inches (1 inch = 25.4 mm). The letter corresponds to the profile of the rim flange. There are several types of rim flanges depending on the type of vehicle.
The J for example belongs to passenger cars, the A to motorcycles, scooters…, the E to trucks, the JJ to 4×4 cars… and so on for each group of vehicles.
16: rim diameter in inches.
H2: rim shoulder profile (contour). This marking is generally located at the end of the series of numbers and letters engraved on the rim and corresponds to the stiffness of the rim. There are several types of rim contours: H, H2, FH, FH2, FH2, EH2…
ET43: is the depth of the rim: the distance between the mounting surface and the symmetry surface of the rim in millimeters.

Well, with the information you have just read, you have seen how the rim marking allows you to identify the type of rims, find out with which tires fit which, in case of accidents, or modifications of the vehicle and therefore you will be able to perfectly identify the type of rim in case you need it.

Machines and types of tire marking

Sivart would like to offer you the possibility to use this material and to make a rim marking with our different marking technologies:

Laser Marking: Marking with laser technology is one of the most widely used today. It is a very suitable technique for processes that require the elimination of noise during marking. Another advantage is its short cycle times.
Micro-percussion marking: The micro-percussion process is characterized by marking a matrix of dots under pressure on a limited surface. Its main advantage is its low cost and effectiveness.

On the other hand, this technique requires secure clamping of the part and has the disadvantage of generating noise in the marking process.

Scratch marking: This technique is quite similar to the previous one, the difference being the marking with a continuous line where the punch presses and scratches the material by compressed air. On the other hand, it has the disadvantage of not being able to generate 2D codes. The fastening of the rim must be much more robust and secure than for micro-percussion.

All the markers that you will find in Sivart have the added services such as installation, commissioning and training for your company, as well as an optimal and fast after-sales service.
