What is stronger cast or forged-YOG Rim?

I believe that many netizens will ask if the wheel frame of a motorcycle is

forged or cast. Since we need to understand the mystery, let us first understand 

the production methods of the two mainstream wheel frames.

1.What is casting?

After the metal is smelted into a liquid, it is poured into the model. After it is 

cooled and solidified, the casting is taken out from the model, and the removed 

casting is called a blank and needs to be trimmed. The material to be cast is 

mostly metal (such as iron, copper, aluminum, etc.), and the material of the mold

 is mainly divided into three types: sand, metal and ceramic; it is often used to 

manufacture mechanical parts with complex shapes or subjected to static load 

and compressive stress.

Moreover, the most important point is that the price of the cast wheel frame is 

relatively close to the people.

In terms of advantages, the casting wheel frame mold has low cost, low 

processing cost, and good efficiency in manufacturing a casting having a 

complicated shape. The disadvantage is that bubbles are generated due 

to no pressure, the tolerance is large, the strength of the casting is low, 

and the environmental pollution is serious.

2.What is forging?

The metal blank is heated to the ideal working temperature and an external 

force is applied thereto to change its shape, density, mechanical properties 

and grain structure, and the processed forgings must also be trimmed. 

According to the workpiece temperature section during processing, it can 

be divided into three types: hot forging, warm forging and cold forging. 

Often used to make mechanical parts that withstand large dynamic loads.

Forged wheel frames are also common in retrofitted vehicles.

In terms of advantages, the forged wheel frame reduces air bubbles and

 changes grain structure due to pressurization, has small tolerances, and 

has high strength for forgings. In terms of shortcomings, due to the high 

cost of the mold, it is not suitable for small-scale production, the process is 

complicated, and the shape complexity is limited.

3.Why is the forged wheel frame better than casting?

The price factor is set aside because forgings have higher strength and 

density and can withstand higher stresses, and the weight of the forged 

frame is lighter than that of a rigid cast frame.

The advantage of the lightweight weight of the wheel frame can reduce 

the energy loss transmitted by the engine to the rear wheel, thereby improving 

the acceleration performance and improving the braking performance.



In terms of price, the forged wheel frame is obviously more expensive than 

casting, but the forged wheel frame is lighter in weight and uniform in mass 

distribution, and the wheel gyro effect is lowered to improve the handling 

performance of the vehicle.
