Round Steel Treatment

To protect our environment, we have abandoned the use of acids to clean and soften material surfaces since 2018. Now we use a vacuum furnace to anneal and soften the material, which will result in more stable material properties and better welding.

Fully Automatic Robot

We have successively purchased fully automatic bending machines, fully automatic welding machines, and fully automatic calibrating machines since 2014

-

We are the first company in the region to have a fully automatic production line.

-

The product quality and production efficiency of the round chain have been greatly improved.

-

The introduction of advanced production technology and maintenance technology has improved the overall level of employees.

-

This laid the foundation for the next step of self-developed production equipment.
Dual Control Medium Frequency Furnace

Heat treatment is the "soul" of the chain

In 2015, we eliminated the Box Furnace and replaced it with the Medium Frequency Furnace. The Medium Frequency Furnace is more suitable for chains than the Box Furnace, and it is easier to control the quenching and tempering temperatures, which is very critical for the chain breaking load and elongation, surface hardness and fatigue strength. This allows our chain to more easily cope with the harsh working environment of underground mines and the lifting of high safety loads. Medium Frequency Furnace save more electricity and reduce carbon emissions than Box Furnace.
CAD/CAE And Fatigue Strength Simulation

When we develop new products, we use CAD to model them, making it easier to process the molds needed for production.

We will use CAE to conduct fatigue strength simulation, which greatly reduces our R&D costs and R&D cycle.

Surface Treatment

Any surface treatment other than self color (surface polish) will reduce the mechanical properties of the chain. The surface treatment used for round link chains depends on the purpose. Some application scenarios require wear resistance, some application scenarios require corrosion resistance, some application scenarios require both wear resistance and anti-corrosion, and some application scenarios only require color as a representation. We can provide surface polishing, carburizing/carbonitriding, electro-galvanizing, hot-dip galvanizing, powder coating, baking paint, electrophoresis,black oxide, aluminum plating, titanium plating, etc. If you're not sure what kind of surface treatment you need, please contact our technicians, all advice is free!

Our chains are mostly exported to more than 30 countries
both in European and Asian markets.
