Mechanical valves in most I-type head engines are removed and re-installed using a “Valve Spring Compressor” considered as “Special Service Tool (SST).”. Removal and re-installation of valves in any automotive engines must ensure and apply safety both on the work and the worker. In this idea, the researchers planned, fabricated and

New manufacturing processes for a valve-spring retainer (VSR) are proposed by replacing the initial solid billet for commercially available thick-walled pipes. The rigid-plastic FEM has been applied to simulate the conventional five-stage manufacturing process for VSR component. The existing process includes mainly backward extrusion and heading operations.

It is used in the Engine of any vehicle. "We manufacture Valve springs from wire dia 1.5 mm to 12 mm." The difference between regular compression Spring and the valve spring is that this spring works in high RPM and hot conditions the temperature may be around 150º C. Also valve spring has a variable pitch in some cases.
