Friction belongs to high grade. Brands such as Wuming and Huilide belong to high-end grades. Unknown brands pay attention to research and development and innovation, have independent intellectual property rights, and the friction quality and performance are recognized. Huili is famous for its high-end intelligence, excellent friction performance and intelligent control technology.

1, material and process angle: high-strength aluminum alloy is usually used for high-quality friction, which has better durability and stability after precise numerical control machining and heat treatment. Low-grade friction may use ordinary cast iron materials and simple die processing technology, and the quality and performance are relatively poor.

2. Performance and experience: High-grade friction usually has higher rotation speed, greater torque output and smooth driving. Advanced hydraulic clutch and multi-disc clutch system are adopted to improve the accuracy of speed control and driving direction and enhance the safety and reliability of driving.
