The quality of a cast iron pulley depends entirely on its casting and machining process.
Our pulleys adopt advanced sand casting technology, using high-strength HT200 / HT250 cast iron raw materials to ensure stable hardness, strong wear resistance and long service life.
The complete production process includes:
- Mold Making: High-precision molds ensure consistent size and stable structure.
- Casting: Molten iron is poured at standard temperature to avoid pores and cracks.
- Shot Blasting: Clean surface and improve material density.
- Precision Machining: Turning, milling, groove processing and balancing test.
- Inspection: 100% full inspection to ensure stability and safety.
We focus on every detail to make pulleys run smoothly, low noise and high efficiency.
