Petrol Engine Valve Spring
custom manufacturer of springs for clutch, coil & engine valves. Types of springs include compression, extension, double torsion, clock & leaf springs. Materials include carbon steel, music wire, stainless steel, titanium
As a major supplier to OEM and aftermarket camshaft manufacturers, we design and build state-of-the art valve springs for all forms of applications as well as springs in fuel injectors, latch mechanisms for valvetrain components, springs in torque converters, and clutch assemblies.
By applying advanced manufacturing techniques such as gas nitriding, surface enhancement and precisely controlled heat-treatment stages, HARD springs minimize load loss while in service.
Technological and Engineering Capabilities
Two advanced laboratories are dedicated to ensuring the quality performance of our engine-powertrain springs.Our scientific and technical staff can process samples for raw material qualification and validation. We use a full range of analytical resources to examine fundamental material properties:
Evaluation of rotating-bending fatigue of wire stock
Measuring tensile yield of competing materials
Microhardness testing to verify hardness profile, residual stress profile, and surface processing effects
Surface roughness and decarburization analysis
Impact testing to measure fracture toughness and notch sensitivity, and to evaluate processing effects.
Laser measurement of valve position to determine precise location throughout the working cycle
Proximity probe focuses on the valve-closing event to determine position, timing, and the occurrence of valve bounce
Rotary cycle and servo-hydraulic fatigue testing
Specialized equipment for evaluating spring rate, spring frequency, spring load, and spring pitch profileand Strain gauging capabilities for springs and valvetrain components
Our engineers are fully experienced in product design, spring design analysis.
Whether you need valve springs for a motorcycle with an 18,000 RPM engine or a low-horsepower engine, Peterson Spring has the technology and the know-how to match you with the proper valve spring to meet your needs.
