During the installation of the mould temperature controller, great care must be taken to avoid any damage to the unit. Adequate space around the mould temperature controller should be allocated in a rational manner to ensure convenient access for its maintenance and servicing. The cooling water system ought to be meticulously designed and installed in strict accordance with the national standard piping system design and construction installation criteria, thereby maximizing the performance of the mold temperature controller.   1. Water Mold Temperature Controllers The heat transfer medium for the water mold temperature controller must be a pristine water source, free from sand, soil, or other contaminants. If groundwater is utilized, it should be softened. The circulating water should be replaced on a regular monthly basis. Water with impurities can readily clog the pipelines and inflict damage on the machine. Unsoftened water is prone to scale formation, which severely impairs the heating and heat transfer efficiencies and diminishes the service life of the heating tubes.   2. Oil Mold Temperature Controllers Prior to operation, it is essential to employ high quality, clean, and heat transfer oil of a unified brand. Brands such as Mobil, Esso, and Total are recommended. The use of inferior heat transfer oil can lead to heater fouling and burnout, pump impeller wear, and a reduction in flow rate, consequently shortening the normal service life of the equipment. The oil mold temperature controller machine should not be moved casually while it is in operation. If the mold temperature controller requires repair, the oil temperature must be lowered to below 80℃ (176℉)  before any repair work can commence. The potential causes of motor overload include power phase loss, pipe blockage, and bearing damage. When the motor is overloaded, the motor overload relay will automatically trip and halt the machine to safeguard the motor. The alarm can be cleared by pressing the "Reset (green button)" switch on the overload relay. Before shutting down the pump, it is necessary to wait until the oil temperature has dropped below 80℃ (176℉)  ; otherwise, its service life will be adversely affected. To achieve a stable control temperature, the cooling water pressure should be maintained within the range of 1 - 3 kg/cm².     In conclusion, correct installation, proper heat transfer medium management, and strict adherence to operational guidelines are vital for the performance and durability of water and oil temperature controllers. Following these instructions and precautions ensures reliable operation, reduces malfunctions, and boosts productivity. Regular maintenance and performance monitoring enhance efficient and sustainable use, protecting the investment in Hengde mold temperature controllers.   Choose Hengde, Choose Perfect Mold Temperature Controller!

In such instances, how can one undertake self-troubleshooting? The following suggestions are presented, and it is advisable to initially examine these solutions.   Common Failures for the Mold Temperature Controllers Cause Solutions 1. Unable to start, no fault indicator light. 2P2A Circuit breaker tripped Open the circuit breaker to check the cause. Phase loss Check the power cord. Transformer burnt Replace the transformer. 2. The indicator light for lack of media is on. The cooling water is not turned on or the pressure is insufficient Open the cooling water valve and check the pressure. Pressure switch problem Adjust the pressure switch or replace it. Insufficient heat transfer oil Add heat transfer oil 3. Pump overload light on. System overload 1. Check whether the hot water inlet and outlet valves are open and press the reset button; 2. Clear the scale of the electric heater. The power supply voltage is abnormal or the phase is missing 1. Use a three-phase meter to measure the three-phase voltage; 2. Check whether the power supply terminal is loose and tightened, and press the reset button. 4. The temperature is too high and cannot be cooled. The solenoid valve is blocked Clean the solenoid valve The solenoid valve coil is aging or damaged Parts need to be replaced. 5. Unable to heat or reach a certain temperature and no longer rise Solenoid valve is blocked or damaged Clean the solenoid valve or replace accessories. Heating tube burns out Replace the heating tube. 6. The fault light is on and the alarm does not sound Alarm failure Replace the alarm.
