Importance of Pneumatic caster wheels

The forged aluminum and pneumatic caster wheels manufacturing process is critical to wheel strength. They are produced by applying extremely high forces to base material in a contained die. The forged wheel blanks, or "pre-forms", undergo very beneficial changes in metallurgical grain structure during this process. The more random grain structure found in standard cast wheels becomes a more highly organized and aligned grain structure when wheels are forged. More importantly, forged wheel metallurgical microstructure in both aluminum and magnesium can be further oriented in the forging process to provide the highest material strength exactly where wheels see the highest loading from road surface hazards or from lateral and other loading generated by the vehicles own inertia. Going one step further, today's advanced computer aided modeling techniques allow the white nylon caster wheels manufacturer and the automaker to collaborate in optimizing a specific forged wheel geometry and design for the utmost strength and safety on the vehicle.

The President of Magnesium Inc. notes that, the wheel weight is very important to overall performance as it is key component in un-sprung vehicle mass. Generally, the accepted rule for thumb for predicting performance benefits from sprung vs. un-sprung weight reduction is a factor of approximately 4:1. For every pound of un-sprung mass eliminated a four fold advantage is gained in vehicle performance parameters. For example, forged magnesium, large diameter wheels which are 20"-22" increase the weight advantage over aluminum by eliminating, on average, 70-75 lbs. un-sprung mass, which would provide the same acceleration time and braking distance benefit as eliminating 250-300 pounds from the vehicle engine, chassis or passenger compartment."

The manager goes on to say that, By virtue of these lighter wheels, forged wheels are at least 20% lighter, sustaining equal loads with better characteristics, which is always easier on the car and its suspension. Lighter wheels also yield shorter breaking distance, which saves lives, shorter acceleration and reduces fuel consumption. SMW Engineering, a division of Magnesium.com is a leader in developing magnesium wheels. Engineers at Magneisum.com acknowledge another important feature of forged wheels over low pressure cast wheels is the integrity of surface finish achievable. Most final wheel styles and finish combinations are enhanced by the density and uniformity of cosmetic surfaces on forged wheels. This is particularly important on higher-end vehicle applications where a bright wheel finish is desired but chrome plating is not an alternative due to mass, cost and environmental considerations.
