The production process of aluminium shot, of spherical type foresees casting of selected scrap and choiced alloys.
The cast material is solidified in particles having a spherical shape through a controlled cast process.
The spherical aluminium shot obtained in this way is subdivided according to dimensions. This process is followed by a final phase, which foresees three different types of checks:
- micro-structural check;
- hardness check;
- further dimensional check.
Uses and Advantages
The cast aluminium shot is featured by very reduced hardness and a very low specific weight like the aluminium pin.
This feature makes it particularly suitable for shotblasting and sandblasting of aluminium and Zn+Al+Mg alloy pieces when a light cleanliness is required with reduced surface roughness.
But the same shots are not suitable, owing to technical reasons, to be used on suction pressure compressed-air cabins for sandblasting.
