The unified standard components that are manufactured in a concentrated manner constitute a unique modular assembly system. Theoretically, these parts can complete ten millions of combinations. In these combinations, the customer must be able to find an ideal solution for their own drive requirements. The modular assembly system requires that all product parts and components must be manufactured using the most modern manufacturing processes and fully automated production lines. This modular assembly system can handle large quantities of processing. Each structural component can be optimally combined and optimized, and it can provide customers with various types of requirements and services at any time with high quality.
