Excavator Track Shoe Bolt

Cold heading:
In this production step, the raw metal material is extruded and shaped through a cold heading process to increase its density and strength. This is the starting step to ensure high quality of excavator track chains.

Hot punch:
The hot stamping process heats the cold-forged material to further change its structure. This helps improve the toughness and durability of the metal to meet the challenges of heavy engineering environments.

Heat treatment:
Through heat treatment, the overall performance of the excavator track chain is further improved. The material undergoes quenching, tempering and other processes at high temperatures to adjust its hardness and wear resistance, ensuring that the track chain can maintain excellent performance under various working conditions.

Nut tapping:
In this link, the relevant nuts on the excavator track chain are tapped to ensure that the threads are firm and precise so that they can be tightly connected with other components to provide a strong overall structure.

Tapping:
This step is a tapping process for other parts on the excavator track chain to ensure the tightness and reliability of each connection point, thereby ensuring the strength of the overall structure.

Hardness testing:
In the final stage of production, the hardness testing link is used to ensure that the excavator track chain reaches the predetermined hardness standard. This step is an important part of quality control to ensure that each track chain meets high standards of performance requirements.
