Purpose and area of application

   Aim of the developed technology is reduction of metal consumption and increase of durability of springs.

   Area of application: the springs manufacturing enterprises and enterprises of motor transport repair.

Advantages

• simplicity of technological operations and methods;
• high efficiency of the process;
• high quality of the products due to accuracy of profile sizes and identity of physic-mechanical properties of a spring;
• opportunity of production of a wide class of parabolic profiles in a single stand of rolls;
• low-laminated parabolic spring on 25-30 % is easier than a usual spring, has more useful loading and provides the smaller charge of automobile fuel.

Dimensions of springs

Length, mm	1500–2200
Thickness on the ends, mm	14–30
Thickness in the central part, mm	8–12
