WPC treatment / List of 6 manufacturers
What is a WPC treatment?
WPC (Wide Particle Concentration) treatment, also known as micro particle shot peening, is a surface treatment technology designed to enhance metal surfaces, improving wear resistance and fatigue strength. This process involves propelling micro particles at high speed onto the metal surface, causing fine deformations and creating compressive residual stress in the surface layer. This increases surface hardness, reduces crack initiation and propagation, and enhances resistance to wear and corrosion.
The key advantages of WPC treatment are its high precision and adaptability to complex shapes and small parts. Unlike traditional shot peening, WPC operates at lower temperatures, minimizing deformation or changes in the base material structure. It is widely applied in automotive parts, aerospace components, tool durability enhancement, and other industrial areas.
Application of WPC treatment
✅ Enhancing Durability of Engine Components
Applying WPC treatment to piston rings and camshafts in automotive engines reduces friction and extends their operational lifespan.
✅ Strengthening Aircraft Components
Treating landing gear parts in aircraft with WPC prevents fatigue cracks caused by repeated loads.
✅ Improving Wear Resistance of Tools
WPC treatment on cutting tools and molds prevents wear and damage, increasing production efficiency.
✅ Reinforcing Medical Devices
Applying WPC to artificial joints and medical-grade stainless steel parts improves resistance to wear and corrosion, ensuring long-term usability.
