Shot Peening


Foundry/ Forge



Key Benefits

Lower production costs due to automatic operation, high output and uniform quality

High specific blast performance: parts are always shot peened in the hot spot of the blast stream where the effect is best

High energy efficiency, high economy: blast wheels fully exploit the energy applied and transform it to blast effect

The well proven separation system always maintains the shot operating mixture within the desired nominal size


  • Continuous throughfeed operation is simple, safe and ideally suited for fully automatic production
  • No intermediate stocking of workpieces, parts tracking is possible 
  • Flexible loading / unloading concepts ideally meet user  requirements
  • Automatic systems with high performance and manufacturing consistency reduce production costs
  • Adjustable dwell times and throughput speeds ensure process-safe, defined peening in uniform quality


  • Suspension springs (automotive industry)

Shot Peening Systems for Suspension Springs

Shot peening is an established technology which is optimally designed to enhance the fatigue strength of components which are subject to high alternating stress. Shot peening makes for lighter components which, optimised with respect to weight and cost / benefit, can be loaded up to the limits of their properties.

Process-Safe Shot Peening

Shot peening is cost effective and reliable. It is often the sole treatment method or substitutes complicated, cost-intensive procedures and can be applied practically, regardless of shape and size of the workpieces – thus permitting a wide field of application. Wheelabrator shot peening systems offer all prerequisites for the reliable process-safe treatment of workpieces of all geometries, sizes and qualities.

Almen testing: Reliability is guaranteed

In the shot peening process, reliability is crucial. Each part will undergo a defined treatment. The blasting intensity can be controlled by determining the Almen value and coverage. Due to the fact that all parameters (throughput speed, blasting time, discharge speed, shot size and distribution) in RDS Shot Peening Systems are defined exactly, it is possible to adjust and examine the Almen intensity and coverage.

Reliability and long life cycle

Wheelabrator RDS shot peening machines have a compact design and require only minimal space. They can be easily integrated into existing production lines. Once integrated into automatic procedures the installation only requires periodical inspection, and operating expenses can be reduced. The components within the blasting zone (housing, blast wheels) are made of high wear resistant material or protected against the abrasive effect of steel shot to extend operating life and reduce costs.

Simple but efficient sealing elements prevent stray abrasive. Specific design measures and close tolerances enable easy replacement of wear parts. 

Maintenance operations can be executed conveniently and quickly thanks to integrated platforms and optimum accessibility via large maintenance doors.


Universal Wheel

The blast wheel is the heart of the blasting machine, as the choice of blast wheel determines the power output and the economics. 

This machine is fitted with U70x500 Universal (indirect drive) shot blast wheels as standard. The Wheels are highly flexible, compact and have rotation in both directions. They provide perfect blast cleaning results and highly convenient servicing features.

The U Blast Wheels are high capacity blast wheels with maximum energy efficiency. Their rugged design means that maintenance is easy, and the special and highly wear resistant cast alloy liners ensure minimum wear and maximum service life of the blast wheel.
