The function of an internal combustion engine valve spring is to provide sufficient force throughout the engine cycle to maintain the tappet in contact with the cam at all speeds within the engine speed range. However, it must not exert such force that will produce unacceptable contact stresses between tappet and cam.

New manufacturing processes for a valve-spring retainer (VSR) are proposed by replacing the initial solid billet for commercially available thick-walled pipes.

During the process route from steel production to finished valve springs, many actions are taken to deal with surface imperfections. The emphasis must be on 

The treatment is carried out in advance of setting after fabrication for the purpose of improvement in fatigue strength of the spring which receives load 

The primary elements added to spring wire are chromium and silicon. Other elements such as vanadium and nickel are also used. Each element is

08/02/2022 · To understand the manufacturing process of industrial valves, we must understand the different steps involved. This process consists of dissolving metal, cutting and shaping material, casting and cleaning up, and machine processing. The final product is tested for quality and tolerance, as well as temperature and pressure.

A method of manufacturing a high strength valve spring for a vehicle engine is provided, which includes (a) forming a high strength wire rod in the form of a spring using a roller type jig, (b) cutting an end of the formed spring using a rotary type cutting blade, (c) performing residual stress removal heat treatment at 390 DEG C. to 410 DEG C. for 20 to 40 minutes, (d) performing shot peening

In house valve spring wire production. We focus on the development and manufacture of operation-optimized valve springs that, due to loads that are as low as 

valve springs is required to be smaller in diameter and higher in strength. The general manufacturing process from steel wire to springs is shown in Fig 

Third, the valve production process. The production process of the valve refers to the sum of various labor processes from raw materials or semi-finished products to finished products. It
