IWM Wear Protection Technology | Facts And Figures
Beware Of The Money Pit:
Loss from downtime and wear
Frequent downtimes or service interventions on your blast wheel system are a costly burden to your production process. The increasing wear of wheel blades creates fissures in the blade surface which have a severe impact on the blast pattern and this in turn causes a growing wear of blast wheel protectors and blast cabinet linings. There is plenty of statistical evidence that the loss of efficiency due to wear exceeds 20% and that the fall of intensity can be as high as 30%! This results in a negative impact on your production processes, machine downtime and an increased maintenance effort. But it does not have to be like that!
Put An End To Wear And Tear:
IWM helps you gain a leading edge over your competitors!
With the use of any of IWM's high-performance blast units wear is no longer a matter of concern for you. Made from IWM specialty materials, our wheels, blades and protective wear linings are designed to guarantee a long service life and to ensure the highest level of quality, safety and reliability at all times, even when used with angular grit with a hardness of 55-64 HRC. Further benefits: all screw connections are designed so as to avoid contact with the blast media, and all wear parts can be replaced quickly and without the need to disassemble the drive motor.
