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.

26/08/  · Step 2: Quality Control. All the raw materials are inspected by our quality control department before the materials into the manufacturing process. Before the raw materials enter the warehouse, the steel casting, rods, forging materials, nuts & bolts, tu , and piping, etc, all have checked the chemical composition, dimension inspection, and

later in the valve spring manufacturing process, this tem- perature may be decreased. Hot presetting. After shot peening, the springs should be hot preset 

Spiral springs for variable valve timing system. Our company's unique patented manufacturing method that meets the needs of our generation.

Springs are generally made of hardened steel. The spring manufacturer has the option of using either pre-hardened steel before forming the spring, or they can also harden the spring after the formation process. The most commonly used spring steels are music wire, stainless steel, chrome silicon, oil tempered wire, and chrome vanadium.

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

One process, called mechanical plating, involves tumbling the spring in a container with metallic powder, water, accelerant chemicals, and tiny glass beads that 

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
