DEGREASING is an operation
to remove oil and grease present on the surface of parts as a by-product of
their manufacturing process. Parts are fed through a tunnel where the degreasing
solution is sprayed so that parts are cleaned thoroughly.
SHOT BLASTING is a mechanical abrasive cleaning. Scale and rust are removed from the surface through the impact of steel spheres (shot), which are scattered over the metal substrate at high speed under controlled conditions
ADVANTAGES
The mechanical cleaning process does not produce hydrogen embrittlement because no hydrogen is generated and absorbed. This is its main advantage
Shot blasting also relieves internal tensions of the metal part originated through its manufacturating process (cold forming).
Shot blasting is an environmentally friendly process because chemicals are
not used to clean the parts.
