Manufacturing method is very important in the overall quality and performance of a wheel.

Here are the most common types of manufacturing techniques employed.

There is a good variety of ways of constructing wheels. Most alloy wheels are made in one, two or three-piece construction types.

One piece is just what it says, a wheel made in a mold as a single piece.

Two piece wheels are made of two separate pieces (center and barrel) that are usually welded or bolted together.

Three-piece wheels are made of three separate pieces. They have a center, and inside rim half, and an outside rim half. They are bolted together using the highest quality fasteners.

The term, car rim refers to the wheels of an automobile. The standard wheels found on most automobiles are basic steel wheels, and many car owners opt to purchase upgraded wheels from the manufacturer or from aftermarket suppliers.

Custom car rims are often made of aluminum and magnesium alloys, and are available in a wide range of styles and sizes for most automobiles.

The manufacturing method is very important in the overall quality and performance of a wheel. Here are the most common types of manufacturing techniques employed:

Forging

Considered to be the best manufacturing process, forging allows for the compression of an aluminum billet (a solid piece of aluminum) into an aluminum wheel using more than 13 million pounds of pressure combined with heat.

This produces a wheel that is both stronger and lighter then a standard aluminum wheel.

A spin-off of forging is called roll forging. In this process, a metal blank is run through rollers with impressions cut into their surface giving the wheel its final shape. This allows the wheel to be produced with less aluminum, reducing weight but maintaining strength.

Low Pressure Casting

This is the most common form of rim manufacturing. Much like a casting, liquid metal is poured into a mold and allowed to harden until the finished wheel is cool enough to be taken out of the casting for finishing.

Counter Pressure Casting

Opposite to low pressure casting, the liquid metal is not poured, rather it is sucked into the mold using a vacuum. This reduces impurities making the wheel much stronger than a low-pressure cast rim.
