Process and Quality
A spring is a flexible component designed to absorb mechanical energy. A length of compression springs reduces under loading conditions.
We produce cylindrical heavy-duty compression springs of up to 1,600 mm length made of 10-70 mm diameter rods. This range covers almost all springs for railroad, motor vehicle, agricultural, special vehicle, oil and gas pipeline applications.
A hot coiling process is used to produce heavy-duty springs. This is the only way to coil railroad springs of large-diameter rods.
The process is based on a combined high-temperature thermomechanical treatment – a well-known method of steel mechanical properties improvement. Additionally, local small deformations are created to form nano-sized substructures contributing to the strength performance of springs.
Unique features of the technology:
Due to all these unique features, we can produce second to none springs.
The main material for springs production is high-carbon and alloyed steels.
Independent tests of heavy-duty springs produced as per the proprietary production process performed by the Ural division of the All-Russian Research Institute for Railroad Transport demonstrated:
