Features

Bulge Joint Bar

Enhanced continuity

Ensure that the track has sufficient continuity as the train passes through, reducing bumps and shocks caused by the joint of the track.

Improve stability

Increase the stability of the track to ensure that the train runs safely and smoothly.

Production technology

Cutting

Use a sawing or shearing machine to cut the raw material to the desired length.

Heating and bending

The cut steel is heated to the appropriate temperature, and the bending machine or die is used to bend it into the desired shape and size.

Bulge or bulge forming

Bulge or bulge forming on the joint rod by stamping, forging or rolling.

Quenching and tempering

quenching treatment to improve its hardness and strength. Tempering treatment to eliminate quenching stress and improve toughness.

Surface hardening

The surface is hardened, such as carburizing, nitriding or induction hardening, to improve its wear resistance and corrosion resistance.

Our factory & quipment

Finishing and inspection

The end face, thread and other parts of the joint rod are finished to ensure the accuracy of the match with fasteners and other parts.

Machining

The joint rod is sandblasted, polished or painted to improve its appearance quality and corrosion resistance.

Surface treatment

The size, shape, surface quality, mechanical properties and chemical composition of the joint rod are inspected and tested to ensure that they meet the production standards and requirements.
