Process of Compound Pulley

Mold:

The process starts with creating a mold that will determine the shape and structure of the compound pulley.

Casting:

Once the mold is ready, the casting process is carried out to pour molten metal into the mold and let it solidify to form the pulley.

Raw materials:

High-quality raw materials are used to ensure the durability and performance of the compound pulley.

Production:

The production process involves shaping, finishing, and assembling the compound pulley to meet the required specifications.

Testing:

Each compound pulley undergoes rigorous testing to ensure quality, performance, and durability before being released for use.

Antirust treatment:

The compound pulley is treated with anti-rust coatings to protect it from corrosion and extend its lifespan.

Separate inspection:

After production and testing, each compound pulley undergoes a separate inspection to verify its quality and functionality.

Marking:

Finally, the compound pulley is marked with relevant information, such as size, model, and production date, for identification and traceability purposes.
