or brass pin
is obtained by cutting brass wire into pieces having the same length of the diameter.
They show grains all having the same dimension and the same chemical-physical features.
Moreover, the nature of the material (drawn wire) and the production system exclude the presence of impurities and grains with inclusions, cavities, blowholes, etc.
It shall be also observed that even if it has a cylindrical shape, it gets a spherical-polyhedral shape in few working cycles, and it keeps it even when its diameter progressively reduces during lyfe cycle.
Uses and Advantages
They are particularly indicated for shotblasting of brass pieces
and offer the following advantages:
- compared to steel shots and stainless steel shots:
- keeping the original colour of brass;
- strong reduction in abrasive consumptions;
- reduction in consumptions of the spare parts of the shotblasting machine;
- absence of pollution due to foreign materials on the sandblasted pieces;
- compared to brass waste:
- availability of various sizes of well defined dimension;
- very high reduction in abrasive consumptions;
- remarkably lower sandblasting times;
- constant roughness of sandblasted pieces according to employed dimensions;
- reduction of dust in the plant deriving from abrasive.
The brass metal shots
can be employed without distinction in turbine plants, with free cast sandblasting machines
and pressure compressed-air cabins for sandblasting
with an optimal performance.
But the same shots are not suitable, owing to technical reasons, to be used on suction pressure compressed-air sandblasting cabins
