Technical Data

Zinc granules in small cylinders are obtained by cutting the zinc alloy wire into pieces of the diameter. The nature of the material (drawn zinc wire) and the production system absolutely exclude the presence of impurities and granules with inclusions, cavities, blowing. , cracks etc. It should also be noted that, despite the fact that it has a cylindrical shape, this abrasive acquires a spherical-polyhedral shape in a few processing cycles

This shape is then maintained, albeit in the face of a progressive reduction in diameter, throughout life without ever giving rise to crushing episodes. Zinc grit is used in turbine blasting machines for deburring and cleaning non-ferrous materials and die-cast or lightly chilled alloy parts

It is especially suitable for:
- cast under zinc pressure
- magnesium die-casting parts (according to BGR 204, zinc sand and zinc alloys with a low copper content are suitable for blasting magnesium castings)
- cast under aluminum pressure.

Because zinc has a specific gravity similar to that of steel and stainless steel, but low hardness and high deformability, the energy transmitted to the part during blasting and blasting is significantly less than that of steel shot or stainless steel shot. The result is a perfectly deburred part with a smooth and shiny surface with a low surface roughness similar to what would be achieved by polishing or grinding.
Other advantages are:
- significant reduction in consumption compared to other types of abrasive, especially with PLUS zinc sand.
- almost zero consumption of sandblasting machine spare parts, which leads to reduced maintenance costs and machine downtime.
- grain interlocking in any holes of the blasted part does not create problems for further machining due to the high deformability and low hardness of zinc.
- The metallic zinc granules can be used without discrimination with turbine systems, with free jet sandblasting and with compressed air sandblasting booths with excellent efficiency.

However, the granules themselves are not suitable, for technical reasons, for use in vacuum blasting cabinets.
