Such industries encompass plastic & rubber manufacturing, the chemical field, electronic production, food & beverage, the wood board industry, die casting, printing, and many others.   How to maintain it? Hengde mold temperature controller maintenance is mainly divided into daily inspection and regular maintenance.   Daily Inspection: 1. Check the mold temperature controller housing and control panel to keep them clean and dry, and avoid using detergents containing acidic and alkaline substances to wipe stains. When wiping the inside with a rag, pay special attention not to damage the electrical parts. 2. Check whether each component is normal, such as checking whether the temperature display of the mold temperature controller is normal, checking whether the parameter setting of the controller has changed; whether there is leakage at the pipe connection, and check whether there is liquid dripping or moisture at the joint. Observe whether the oil pump, water pump and other running parts have abnormal noise or vibration. The sound should be stable and there is no obvious shaking during normal operation. Check whether the cable is damaged or worn, and replace it in time if necessary.   Regular Maintenance: Perform in-depth maintenance on the mold temperature controller every certain period of operation (according to the requirements of the equipment manual). The following is the maintenance time of each accessory: Item Maintenance Period Maintenance Solenoid valve 1 month (actual operation 600 hours)  Dismantling and cleaning Liquid level switch 1 month (actual operation 600 hours)  Dismantling and cleaning Mold connection hose 2 month (actual operation 1200 hours) Dismantling and cleaning Noise / strange smell / heat Every day No Noise / Vibration Loose terminals 3 months Inspect and tighten Dust and garbage in control cabinet 1 month Clean Electromagnetic contactor (Pump)  3 years Replace Liquid level display tube Every day Check for proper amount Heat transfer oil 6 months Replace PC board  3 years Replace Pump 1 year(Every day)  Confirm noise Pipeline 1 month  Check and confirm no oil leakage   Special Precautions: 1. It is best to clean the equipment return filter once a month. After the test machine is completed, it is best to clean it several times before normal use. 2. Tighten the screws of all electrical parts of the equipment once a month (especially the contactor, because the long-term operation of the mold temperature controller may cause the screws to loosen); 3. Before shutting down, it is recommended to lower the temperature of the water mold temperature controller to below 40℃ and the temperature of the oil mold temperature controller to below 80℃ before shutting down, which can extend the service life of the pump and heating tube. 4. If the customer's equipment pipeline is higher than the oil tank of the Hengde mold temperature controller, the oil tank can be raised, or the inlet and outlet valves can be turned off first, and then shut down to prevent backflow when the circulation pump is not working.   Choose Hengde, Choose Perfect Mold Temperature Controllers!

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!

A mold temperature controller (MTC) plays a key role in stabilizing mold temperature and ensuring consistent product quality in injection molding, die-casting, extrusion, hot-pressing, and many other industrial processes. Whether you are using a water mold temperature controller (MTC) or an oil mold temperature controller(MTC), equipment failures can quickly disrupt production and lead to higher scrap rates or machine downtime.   To help operators deal with issues more efficiently, this article summarizes common failure points and practical solutions. Below is the troubleshooting table used by most technicians for quick diagnosis.   Common Problems for Mold Temperature Controllers (MTCs) Common Problems 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.
