Ductility Testing Machine
The Machine consists of the following.
Stainless steel bath
Temperature controller (Thermostatic/Digital)
Immersion electric heater
Constant speed Pump cum stirrer
Carriage holding up to three standard briquette moulds
Electric motor with gear mechanism
Stainless steel scale and pointer
The apparatus consists of water bath with a thermostatic heater and a circulating pump to maintain uniform water temperature. One half of the briquette moulds is fixed in a fixed plate in the water bath, the other half of the briquette mould is fixed to a carrier which slides over a rotating threaded shaft with a clutch. The motor and gears to rotate the shaft are housed in a cabinet fixed above the other end of the both. A pointer fixed to the carrier moves over. a scale graduated from 0-110 cm x 1mm fixed on the bath with “0″ (Zero) of the scale towards the fixed plates side. The rotating shaft has 2 speeds of travel for the bracket, 5 cm/min. and 1cm/min. selected by a clutch. Water bath inside is of Stainless steel with insulation and a water drain. A heater with thermostatic control is fitted. inside the water bath. Control switches for motor, stirrer, heater and indicator lamps are fitted to a control panel located at a convenient place on the water bath. Complete with three briquette moulds and one base plate. Working on 230 Volts, single phase, 50 cycles, AC.
