  • Essential Precautions and Pro Tips for Mold Temperature Controllers Nov 27, 2021
    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!
  • How to Start and Stop a Mold Temperature Controller Correctly? Apr 21, 2025
    Hengde Company is a well - established leader in the industrial temperature control industry. With years of experience and a focus on innovation, we offer top - notch mould temperature controllers that are trusted by industries worldwide. Our mould temperature controllers are designed to ensure efficient and reliable temperature control, backed by excellent customer service.   Preparation before starting the mould temperature controller: 1. Turn on the power after opening the valves of cooling water, circulating water, and hot water inlet and outlet.   2. Set the temperature control meter to 0℃ and press the start button.Press the start button, and the following situations may occur: 1) The pump reversal indicator light is on and the buzzer alarms; Processing: Turn off the power, swap any two phases of the external three-phase power line, and connect them back. 2) The pump overload indicator light is on and the buzzer alarms; Processing: Please press the reset button of the pump thermal relay and check whether the three-phase power is missing. 3) The lack of media indicator light is on and the buzzer alarms; Processing (water mould temperature machine): Check whether the water source switch is turned on, or the water supply pressure is insufficient. The water supply pressure of the water mould temperature machine is required to be 1.5KG. If the water pressure is not convenient to adjust, the low-pressure limit pressure of the low-pressure switch can be adjusted. Processing (oil mould temperature machine): Add thermal oil.   3. Set the thermostat to the required temperature.   Start-up process of mould temperature controller: * Water mould temperature controller: 1. Set the temperature to 0℃ first, circulate for 2 minutes, and then set it to the required temperature. 2. If it is not used for a long time, please turn off the main power, remove the connecting pipe, and drain the circulating water in this machine.   * Oil mould temperature controller: Warning: For the first installation or replacement of piping, after heating to the middle position of 1/3 of the liquid level tube, you need to wait for ten minutes before turning it on, otherwise the heating tube may be damaged. Please note! 1. Set the temperature to 0℃ first, circulate for 2 minutes, then set the temperature to 80℃, circulate for 5 minutes, and then set the temperature to 120℃ (if the pressure is unstable at 120℃, please reduce the temperature to 110℃, wait for the pressure to stabilize, and then increase it to 120℃), wait for the pressure gauge pressure to stabilize, and then set it to the required temperature. 2. If it is not used for a long time, please turn off the main switch, remove the connecting pipe and drain the circulating oil in this machine.   Mould temperature controller shutdown process: 1. When shutting down, it is best to lower the temperature of the water mould temperature controller to below 40℃ first, and the oil mould temperature controller is best to lower the temperature to below 80℃ before shutting down, which can extend the service life of the pump and heating tube. 2. If not used for a long time, please turn off the main switch, open all ball valves, and discharge the circulating oil/water in the system.   At Hengde Company, we are committed to providing not only high - quality products but also continuous support. Our technical team is always ready to assist you, ensuring your production processes run smoothly with our mould temperature controllers.   Choose Hengde,Choose Perfect Mould Temperature Controller!
