Railway Shot Blasting Equipments

   Railway Shot Blasting Equipments
 
railway components shot blasting machine  
Shot Blasting is used extensively for cleaning various items like complete coach prior to painting, carriage frames, bogie bolsters, helical springs, leaf springs, cylinder liners, manganese steel crossings, etc.

We are registered with central organisation for modernization of workshops (COFMOW) and supplied more than 20 machines for various applications to railway workshops. We are also registered with BHEL, ORDNANCE Factory (Defense), BEML, and many public sector undertakings.

The figure 1 show internal cleaning machine for DLW (Disel Locomotive Works). The cylinders are shot blasted from inside with aluminum oxide to remove rust, scaleand give uniform to each surface prior to hardcrome plating.

24 to 27 meter long newly fabricated rail coach including under section is cleaned in 3-4 hours in 16 wheel shot blasting machines prior to painting. Previously it took 16 to 20 hrs to cleaned in air blast room.

Shot blasting essentially gives longer paint life on rail coach. Various experiments have proved that the length of paint life depends mainly on the strength ofbond between the paint and the basic surface. The quality of this bond depends on the complete and through removal of mill scale, rust and other contaminants prior to painting and on obtaining an uniformly etched surface.
