Vacuum sandblasters: vacuum shot peening process performed with glass microspheres is currently considered the best treatment to prepare a surface for a subsequent protective coating treatment. This process produces chemically and physically clean surfaces and also improves the resistance, to the fatigue, of mechanical organs submitted to cyclical burdens. Shot peening performed with glass micro-spheres removes any surface tensions, cleans and seals cracks and microscopic slots, as well as any dents caused by corrosion and oxidation traces invisible to the naked eye. Shot peening performed with glass micro-spheres does not alter the outer dimensions of the parts under treatment. With these machines it is also possible to use corundum, ceramic and micrometer metal grains.


High-pressure sandblasters: the high-pressure sandblasting/shot peening is adopted when the use of metallic abrasives is required or to speed up any treatments performed with not-abrasive products, such as ceramic and glass micro-spheres, or with abrasive product, like corundum and metal grains. The blasting material is continuously cycled from the treatment chamber to the pressure reservoir through a filtered separator cyclone and when the filter has removed all the impurities is automatically cycled again. Constructed mainly with stainless steel, these machines are designed to be flexibly employed, is possible to add at them the following optional:
• side doors
• rotating table on a fixed pivot or trolley
• motorized tumbling barrel
• planetary device with satellites
• devices used to convey irregularly-shaped items


Special high-pressure or vacuum sandblasters: the production of standard sandblasters – shot peening machines is put side by side at job order production, according to customers’ requirements, from large-size sandblasting booths, for several operators, to satellite automatic plants controlled by PLC. For both, standard and special machines, are available some optional:
Pedal control
Lateral doors
Lateral aperture
Motorized tumblers
Automatic handling
Pressure/depression circuit
Increased cyclones
Cartridge filtering
Hose filtering
Lateral trolley
