Introduction
Shot peening, a vital surface treatment process, has emerged as a cornerstone in enhancing the durability and performance of metal components. By bombarding a material's surface with small spherical media, this method introduces beneficial compressive stresses, mitigating fatigue and cracking. As industries like aerospace, automotive, and energy demand higher resilience and longer lifecycle components, the importance of shot peening machines continues to grow. In 2025, the global market is undergoing a transformative shift driven by automation, smart technologies, and eco-conscious innovation.
What is a Shot Peening Machine?
Core Principles of Shot Peening
Shot peening involves propelling small round media (commonly steel shot, ceramic beads, or glass beads) at high velocity onto a material's surface. This controlled process induces compressive residual stress layers that improve resistance to fatigue, corrosion, and stress cracking—making it indispensable in high-stakes applications.
Differences Between Shot Peening and Sandblasting
While both processes involve media impact, shot peening is fundamentally different from sandblasting. The latter is primarily abrasive and used for cleaning or texturing surfaces. Shot peening, on the other hand, is a precise mechanical treatment aimed at enhancing structural integrity without material removal.
Common Shot Peening Media Types
Steel shot – Durable, reusable, and widely used in aerospace and automotive.
Glass beads – Gentle impact for lighter components.
Ceramic beads – High performance in high-temperature applications.
