Increasing of battery life!
In robot industry, they have been development of robotics-related with a focus on Silicon Valley from 1980s. In recent years Drone is the most pay attention in robot industry. But Drone have problems to be solved such as low battery life due to heavy weight and electromagnetic interference due to metal parts.
Plastic screws are optimum products for weight saving. Because they are one-fifth lighter than metal screws, and specific gravity of material is about one-sixth lighter than iron and about one-fifth lighter than SUS. Some plastic screw is made by prevention of radio-frequency interference material, it is possible to prevent radio-frequency interference and increase Wi-Fi range by using this product.
