Process of Compound Pulley
Mold
The first step in the production of a compound pulley involves creating a mold that will be used to form the pulley.
Casting
Once the mold is ready, the raw materials are poured into the mold and allowed to harden, forming the shape of the pulley.
Raw Materials
The materials used in the production of compound pulleys are carefully selected for durability and performance.
Production
The actual production process involves shaping, heating, and cooling the raw materials to create the finished pulley.
Testing
Each pulley undergoes rigorous testing to ensure quality and performance standards are met.
Antirust Treatment
After testing, the pulleys are treated with anti-rust solutions to protect them from corrosion.
Separate Inspection
Each pulley is inspected individually to check for any defects or imperfections before packaging.
Marking
Finally, the pulleys are marked with necessary information for identification and tracking purposes.
