BLAST CLEANING OF HEAVYWEIGHT CASTINGS

 

Fonderie Mora Gavardo Spa, Italy

 

 

BACKGROUND

Fonderie Mora Gavardo Spa currently a member of Camozzi Group has been cleaning all the heavyweight castings since 1996 with a Blastman Robot-operated blasting chamber. The operational blast cleaning facility was completely destroyed in 2013 by fire.  After a comparison of different cleaning methods and based on more than 15 years of experience Mora decided to rebuild the new blast cleaning room based on the Blastman robot-operated blasting.

 

OBJECTIVES

The original requirement since the first delivery has been to clean even the most complicated heavyweight castings completely by robot operating blasting nozzle efficiently minimizing manual operations.

 

Evolution in cast-iron castings

In its continuous process of growth and development, which culminated with the entry into the Camozzi Group, Fonderie Mora Gavardo has structured a unique offering of medium and large-sized castings.
