Product Selection Differences for Shot Peening, Peen Forming

Shot peening and peen forming are surface engineering processes that utilize the impact of small particles to modify the surface properties of materials.

  1. Shot Peening:

    • Purpose: Shot peening is primarily used to improve the fatigue life, strength, and resistance to stress corrosion cracking of components.
    • Process: Shot peening involves bombarding the surface of the material with spherical media (usually steel shot, glass beads, or ceramic beads) at a high velocity to induce compressive residual stresses.
    • Effects: The impact of the media on the surface creates a residual compressive stress layer which helps to prevent the initiation and propagation of cracks.
    • Applications: Shot peening is commonly used in industries such as aerospace, automotive, and manufacturing to enhance the performance and longevity of critical components.

  2. Peen Forming:

    • Purpose: Peen forming is used to shape or deform materials through controlled hammering or pressing without causing damage or fracturing.
    • Process: Peen forming involves using a peening tool to deliver controlled impacts to the material's surface, causing localized deformation and reshaping.
    • Effects: Peen forming allows for precise shaping of components without the need for traditional forming processes like bending or stretching, leading to improved dimensional accuracy.
    • Applications: Peen forming is commonly used in industries such as aerospace, automotive, and metalworking for forming complex shapes or modifying material properties.

Key Differences to Consider: - Purpose: Shot peening is primarily for improving material properties, while peen forming is for shaping and forming components. - Process: Shot peening creates compressive stresses, while peen forming induces controlled deformation. - Effects: Shot peening enhances material strength, while peen forming changes the shape of the material. - Applications: Shot peening is more suited for enhancing fatigue life, while peen forming is used for shaping components with precision.

When selecting between shot peening and peen forming, consider the specific requirements of your application, such as whether you need to enhance material properties or shape components reliably and accurately.
