Abstract: A solenoid testing system for testing a solenoid is provided. The solenoid testing system includes a housing member having an inner surface and an outer surface. The solenoid is positioned on the outer surface. The solenoid testing system includes an armature adapted to move towards the solenoid upon generation of the magnetic field by the solenoid. The solenoid testing system includes at least one measuring device connected to the armature for measuring a value of a displacement parameter and a value of a load parameter associated with the armature. The solenoid testing system also includes a controller in communication with the measuring device. The controller is configured to determine an operational state of the solenoid, based on comparison of the value of the displacement parameter and the value of the load parameter with a first predefined set of values and a second predefined set of values, respectively.

Abstract: A method for treating a contaminated metal powder obtained as a residue of a metal deposition process is provided. The method includes receiving, by a vibratory filtering apparatus, the contaminated metal powder generated during the metal deposition process. The contaminated metal powder is received from a top end of the vibratory filtering apparatus. The method further includes filtering the contaminated metal powder by passing the contaminated metal powder through a plurality of filter plates. The plurality of filter plates are so positioned sequentially along a height of the vibratory filtering apparatus that dimensions of a first plurality of holes of a filter plate are larger than dimensions of a second plurality of holes of a subsequent filter plate placed below. The vibratory filtering apparatus is vibrating during the filtering of the contaminated metal powder. The method further includes obtaining, by a receptacle, a filtered metal powder that is reusable.
