Our Facilities
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:
WEDM for die
WEDM for die
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 plate punching for industrial chain
Automatic plate punching for industrial chain
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.
High-speed pin cutting machine
High-speed pin cutting machine
Our high-speed pin cutting machines reach 300 cuts/min, guaranteeing a pin length deviation ≤0.1mm.
Mesh belt conveyor furnace
Mesh belt conveyor furnace
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.
Multi-purpose furnace
Multi-purpose furnace
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.
Automatic assembling of motorcycle chain
Automatic assembling of motorcycle chain
High-speed automatic chain assembly line, full with chain parts feeding, assembly, detection, pre-stretching, running, riveting, and oiling process.
Automatic assembling of agricultural chain
Automatic assembling of agricultural chain
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 robot
Welding robot
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.
Material Spectrum Analyzer
Material Spectrum Analyzer
The material spectrum analyzer offers highly precise and stable analysis on chemical components, requiring only 10-20 seconds from sample reading to report projection.
Micro-hardness tester
Micro-hardness tester
The micro-hardness tester offers extreme precision testing on hardness, high-frequency hardening and carburization surface distribution of various materials.
Breaking load tester
Breaking load tester
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!
Fatigue test machine
Fatigue test machine
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 machine
Wear-resistance testing machine
Wear-resistance testing is critical to accurately measure and improve the wear resistance performance of a chain, in order to optimize its working life
