Process of Compound Pulley:

Mold:

The pulley design is created and a mold is made for casting.

Casting:

The molten metal is poured into the mold to shape the pulley.

Raw materials:

High-quality materials are used to ensure durability.

Production:

The pulley is manufactured with precision and attention to detail.

Testing:

Each pulley undergoes rigorous testing to ensure quality standards are met.

Antirust treatment:

A special coating is applied to prevent rust and corrosion.

Seperate inspection:

Individual inspection is carried out to check for any defects.

Marking:

The pulleys are marked with identification for traceability.

What is the function of the tensioner and idler pulley?
