Description

What is shot peening?

Shot Peening is as simple as the process of shot blasting, but with a perfectly controlled process, creating a high value activity, the most technical one among metallic abrasives applications. Winoa’s expertise and know-how are key factors for your success in reaching this application’s high level of performances.

Shot peening process is used in multiple industries to extend the service life of a component. The process induces a compressive stress layer to increase resistance to fatigue (propagation of cracks, stress corrosion, etc).

To name a few, peening are used on automotive parts (gear, cams, clutch, coil and suspension spings) to aerospace (landing gears to turbine blades), energy sector (rock drills and windmill gears) to Railcars (wheels and coupling peening) and many others.

High Durability Cut Wire peening

High Durability Cut Wire

Our high-durability conditioned Cut-Wire, manufactured by our partner Toyo Seiko in Japan (the world leading company for shot-peening media), is a specially heat-treated Cut-Wire for an extended shot life-time.

This extended life not only reduces shot consumption, but for critical peening applications, it ensures a more constant operating mix and peening shot size, reduces variables related to shot addition and control, resulting in a safer peening process.

UFS Ultra Fine Shot

When some applications requires very small beads due to sharp radius and for precise shot peening, our high hardness, highly spherical shape high carbon micro shot will meet your needs.

With average sizes  from 50 µm  to 150 µm, and with a hardness above 770 Hv (63 RHc), our UFS shot is your solution to treat these complex shapes. They are commonly used in peening gears for electric cars, springs or molds, but also for dual peening to increase compressive residual stress on the outer layer of the surface.
