Automotive wheels carry both the body and the safety of the driver and rider, but most people tend to focus only on the configuration of the car and rarely pay deliberate attention to the car wheels.
Wheel rims are also called hubs. Car wheels are mainly divided into steel wheels and alloy wheels in terms of material.
Today's car manufacturers have included aluminum-alloy wheels as standard equipment. Alloy wheels are generally mostly aluminum alloy, compared with steel wheels, aluminum alloy wheels have higher precision, are safer, and have other characteristics.
Automotive hub molding methods are divided into casting molding, forging molding, etc.
This article you are reading briefly introduces 4 types of automotive wheel hub molds.

Gravity casting is the most traditional process, in which the metal is melted into a liquid that meets certain requirements and is poured into the gravity wheel mold and allowed to cool naturally, and then the casting of a certain shape is obtained after the cleaning process.
The wheels made by gravity wheel mold making are less dense and simple to produce at a lower cost.

Low-pressure casting is a new type of fast casting method. Low-pressure automotive wheel molds are improved on the basis of gravity casting.
LPDC wheel mold design can improve the defects of gravity wheel molds, therefore, LPDC wheel molds (Low-Pressure Die Casting) have become the most common way to manufacture wheels.
For wheel hub manufacturers, the LPDC wheel mold tool has high output, the low pressure allows for more complex shapes, better quality finished products, and reasonable prices.

Flow-formed aluminum automotive wheel forming is a casting method - a manufacturing technique in which molten metal is poured into the cavity of a wheel manufacturing mold.
Aluminum is one of the most commonly used die casting materials, and flow form molds design allows for precision and repeatability in each component. As a result, flow die-cast aluminum automotive wheel molds have higher strength and better toughness than gravity wheel molds and low-pressure wheel molds.
Forging is a processing method that uses forging machinery to apply pressure to metal blanks to produce plastic deformation in order to obtain forgings with certain mechanical properties, certain shapes, and sizes.
Forged wheel die uses ultra-high pressure die to press the whole metal into shape at one time, and the pressure can reach 4000kg/cm. The range of wheels made by forged wheel mold tools is far beyond that of casting, so the price is higher.
Wheels made by forged wheel mold casting have better density, no air holes, and weigh more than 20% lighter than castings of the same size.
Different types of automotive car wheel molds have their advantages and disadvantages, and the right one is the best one. The lightweight of automobiles is the eternal theme, and we believe that the new material and technology of wheel manufacturing will also have new breakthroughs.
