With 5 manufacturing plants covering over 50,000sqm, and close to 1000 employees, SFR Chain has invested in cutting-edge technology to offer the highest quality standards, and efficient economies of scale. Some of the manufacturing equipment that we use for manufacturing and quality testing:
Wire cut Electrical Discharge Machining is used for the manufacture of complex die and progressive die. By multiple cutting, the material deformation and molybdenum wire loss will be reduced, so the processing quality is also substantially improved.
Automatic punching of plates with high speed and high precision, to guarantee reliability and efficiency. This machine is noise-insulated, to comply with environmental protection measures and keep a good working environment.
Our high-speed pin cutting machines reach 300 cuts/min, guaranteeing a pin length deviation ≤0.1mm.
Not every manufacturer has furnaces like ours. Our mesh belt conveyor furnace was built adopting international advanced technology, and it is used for roller and bush carbon-nitriding heat treatment.
This multi-purpose furnace was also built according to cutting-edge European technology, and it is used for pin, roller and bush carbon-nitriding heat treatment.
High-speed automatic chain assembly line, full with chain parts feeding, assembly, detection, pre-stretching, running, riveting, and oiling process.
Automatic assembly line for agricultural chain, with effective combination of mechanical die and pneumatic hydraulic parts by mechatronic design, to achieve automatic assembly of complex structure chain with special attachments.
Welding robots can significantly improve the welding quality of parts, improve efficiency, and effectively protect workers' health. We are proud of our high–quality welding, which helps us stand out from other manufacturers.
The material spectrum analyzer offers highly precise and stable analysis on chemical components, requiring only 10-20 seconds from sample reading to report projection.
The micro-hardness tester offers extreme precision testing on hardness, high-frequency hardening and carburization surface distribution of various materials.
The breaking load test is the most basic performance test, pulling the chain until it breaks. The pull force must meet the standards. This is the most basic factor to measure the performance of the chain, yet it still is one of the coolest machines in our QC lab!
The fatigue test helps determine a chain’s ability to withstand cyclic fatigue loading conditions. This characteristic is extremely important in any industry where a chain is subject to fluctuating instead of constant forces.
Wear-resistance testing is critical to accurately measure and improve the wear resistance performance of a chain, in order to optimize its working life
