Characteristics of DCC Cast Chains

• Material

Made from high-quality alloy steel or carbon steel through forging processes,it boasts excellent tensile strength and impact resistance.

• Chain Structure Type

The chain's grain structure becomes denser through forging, resulting in fewer internal defects and significantly improved overall strength and durability.

• Chain Link Structure

The link is the basic unit of a cast chain,typically shaped either elliptically or circularly.Each link is formed integrally through casting, ensuring structural strength and consistency.In some high-strength cast chains, reinforcing ribs are designed inside or outside the links to enhance their tensile strength and resistance to deformation.

• Connection Method

Open-link chain connection,pin connection,bolt connection,welding connection,snap-fit connection.

• Surface Treatment Process

The surface has undergone heat treatment such as quenching or tempering,or special coating processes,providing excellent wear resistance suitable for harsh operating conditions.

• Special Design Features

Automated welding robots were used to weld the sleeves to the side panels, ensuring stability and uniformity at each weld point.

Performance Indicators of DCC Cast Chains

• Service Life

Our cast chains,which utilize automatic welding technology,high-frequency heating treatment,and corrosion-resistant surface processes,have a longer lifespan than ordinary chains,especially in environments with severe wear and harsh conditions.

• Operating Speed Range

Suitable for various operating speed ranges,it prevents chain damage or low transmission efficiency caused by speed mismatch.

• Temperature Adaptation Range

Designed for extreme environments,our cast chains can operate across a wide temperature range,from -40°C to +300°C.

• Anti-corrosion Performance

Thanks to precise surface treatment processes,our cast chains have excellent corrosion resistance,making them particularly suitable for environments with high humidity and strong corrosive conditions.

• Wear Resistance

Using high-frequency heating and surface reinforcement,long-term use ensures no significant wear or performance degradation.

• Noise Level

Precise welding techniques and stable structural design reduce friction and collisions between chains,thereby lowering mechanical noise and improving the working environment in factories.
