The Abrasive Blasting is an impact surface treatment technique used to obtain an excellent grade of cleaning and polishing of the surfaces.
The Abrasive Blasting is a process used in the most of industries that work with metals, including aeronautics, automobile, construction, navy, railways, etc.
The blasting process is based on propelling a stream of abrasive material at high velocity, during which impact the surface of the metallic part, causing the removal of surface contaminants, such as paint, oxide, calamine, waste from casting, etc.
The Abrasive Blasting stands out as a very reliable and automated cleaning process that gives optimum surface preparation of the metal before plating.
Elhco has three blasting machines: the multitavola, with 20 plates of 200 cm diameter and 150 cm hight, the T-14, with one plate of 1500 cm diameter, and the L-50, a machine used to blast in barrel, with a maximum charge of 40 kgs.
The abrasive medium used is usually made from casting steel with beads of 0.12 – 0.42 mm and hardness of 60 HRC. However, depending on specification and customer requirements, we can use any type of abrasive media.
