What is the difference between plastic and metal gear reducer?

What is the difference between a plastic micro gear reducer and a metal micro reducer? Before we understand this problem, let's first understand what plastic structure and metal structure are.
 
The plastic structure of the reduction gear box is made of special plastic, has good wear resistance and pressure resistance and can withstand the general transmission pressure and load capacity. When a certain fatigue index or corrosion critical point is reached,the drive shaft will be broken and damaged, thus stopping the work; the plastic structure is characterized by low noise, low energy consumption, light weight, low price, and the manufacturing process is simpler than the metal structure.
 
 
The metal reduction gear box is made of powder alloy die-cast or stainless steel, which has good rigidity and durability, and is not easy to break the shaft. The disadvantage is that the noise is large, the manufacturing process is complicated, and the price is higher than that of the plastic structure reduction gear box.
