From mobile phones to vehicle bodies,most products and items of equipment undergo vibration testing as part of their development or quality assessment.

Cambridgeshire-based 1G Dynamics, which specialises in vibration test system repair and maintenance, has installed a customised blast cabinet from Hodge Clemco to upgrade its services).

Repairing the electric coils in vibration test systems involves stripping the copper wiring off the aluminium armatures, along with any aluminium tube used for cooling the equipment.

The surface of the armature (and the cooling tube) is then prepared to provide a key for the final resin coating after rewinding (www.1g_dynamics.com.

The Hodge Clemco cabinet allows the armatures to be processed with a hand-held blast gun, while tubes are dealt with semi-automatically by means of four nozzles positioned around an exit hole in the chamber.

All four faces of the square tubes are treated, as they are pulled through the chamber.

The chamber measures 1,250 x 1,000 x 1,500mm and has high-quality illumination, a viewing window and fully sealed glove ports.

Its double-skin construction reduces noise, and extra ventilation has been included to improve visibility.

Boron carbide nozzles fitted to the five blast guns provide long-term durability.
