How to Distinguish Forged and Cast Wheels?

[NoraLynn]

Methods to distinguish forged and cast wheels are as follows: 1. Sound Test: Wheels made from high-quality aluminum are denser, so they produce a clearer ringing sound when struck. Wheels manufactured using liquid aluminum forging technology produce the clearest sound, with echoes sometimes lasting several seconds. If the sound is dull or almost nonexistent, it's best to avoid them. 2. Surface Inspection: High-quality wheels not only have excellent surface coating but also rarely have sand holes. Inspect each wheel carefully before purchase to ensure there is no deformation or wear caused by packing or transportation. 3. Dynamic Balance Test: Place the new wheel on a dynamic balancing machine for testing. First, visually check if the rim is round during rotation—if it appears visibly out of round, discard it immediately. If it appears round, check the wheel's imbalance. According to OEM standards, wheels with less than 30g of imbalance are generally acceptable.
