16 2. Structure Characteristics and Working Principle 2.1 Working Principle System flow for STM-405E (Indirect Cooling) Picture 2-1:Working Principle The high temperature oil returns to the machine and then be pressured by pump to the heater. After being heated, oil will be forced to the mould and continue the circle. In the process, if the temp. is too high, the system will activate the solenoid valve to let cooling water lower the temperature indirectly until the it reaches the system requirement. If the temperature keeps increasing and reaches the set point of EGO, the system will alarm and stop operation. The system will sound low level alarm and stop working if oil level falls down below the set point. 16(57)

17 System flow for STM-405N-WE (Direct Cooling) Picture 2-2:Working Principle The high temperature water returns from the mould to the temperature controller machine is pressurized by pump and conveyed to the heater. After being heated, it will be again flow to the mould to maintain the temperature, and this circle repeats. In the process, if water temperature is too high, system will activate the solenoid valve to let cooling water directly cool down the high temperature water to maintain constant temperature. If the temperature keeps increasing and reaches to the set point of EGO, machine starts high temperature alarm and halts; if system pressure is too high and reaches the set value of high pressure switch, system will launch high pressure alarm and halts; when cooling water pressure fails to reach the set value, pressure switch will send a signal of water storage to launch low pressure alarm and machine halts. 17(57)
