Features:

1. Diversification: includes engine parts, pump parts, transmission parts and other types to meet different functional needs.

2. High precision: such as piston, cylinder liner and other key components, need high precision processing and coordination to ensure the efficiency and stability of the gasoline engine.

3. Wear resistance: Components such as impellers need to have good wear resistance to extend service life.

4. Corrosion resistance: Some parts exposed to the external environment need to have a certain corrosion resistance to cope with poor working conditions.
