Mold Temperature Controller Oil

Mold temperature controller(MTC), also known as mold temperature machine, was originally used in the temperature control industry of injection molds. Later, with the development of the machinery industry, mold temperature controllers were used more and more widely. Now mold temperature controllers are generally divided into water mold temperature controllers and oil mold temperature controllers. If the selected mold temperature controller matches the temperature requirements of product molding, it can greatly improve the quality of the product and reduce the operating cost of the product.   So how to choose a mold temperature controller that matches your process requirements? Before making a purchase, consider the following important factors to ensure your system fits your production needs. Selecting the Right Mold Temperature Controller Selecting the right mold temperature controller requires evaluating your process needs. Consider the heat transfer medium, cooling method, and the required temperature range for your application. Assess the mold size and heat capacity, pump flow and pressure, and the capabilities of the control system. Don’t forget safety features and balance the purchase cost versus operating cost. Addressing these factors ensures consistent mold temperature, reliable performance, and long-term efficiency. 1. Heat transfer medium: thermal oil / water. Water mold temperature controller: Water-type mold temperature controller uses water as a heat transfer medium and is suitable for occasions where the temperature control requirement does not exceed 200°C. Its advantages are high heat transfer efficiency, environmental friendliness, and relatively low cost. Oil mold temperature controller: Oil-type mold temperature controller uses oil as a heat transfer medium and is suitable for high-temperature occasions. The temperature control range can reach 350°C. Oil type mold temperature controllers are suitable for industries with high temperature control requirements, such as the hot pressing mold industry.   2. Cooling method: direct cooling / indirect cooling Direct cooling: Direct cooling is suitable for applications that require rapid cooling, such as certain plastic processing processes. This method can quickly reduce the temperature of the heat transfer medium and improve production efficiency. Indirect cooling: Indirect cooling uses a cooling circuit separated from the main circuit. It is suitable for applications that require more precise temperature control, such as precision mold processing. With an independent cooling circuit, temperature changes can be controlled more finely.   3. Temperature control range: low temperature application / high temperature application Low temperature application: Taking the plastics industry as an example, due to its relatively low temperature requirements, water mold temperature controllers(MTCs) can meet the requirements. The temperature control accuracy of water temperature controllers is roughly ±1℃, which is sufficient to meet the needs of most industrial application scenarios. High temperature application: In the case of high temperature applications, such as rubber pressing or metal casting, where high temperature control is required, oil mold temperature controllers(MTCs) are suitable. Oil type mold temperature controllers can not only achieve a wider temperature control range, but also perform better in thermal stability.   4. Mold size and heat capacity Large molds often require mold temperature controllers(MTCs) to have sufficient heating or cooling power to quickly reach and maintain the required temperature. Molds with large heat capacity require more energy during heating or cooling. For example, a large automotive parts injection mold has a much larger heat capacity than a small plastic toy mold, so a more powerful mold temperature controller(MTC) needs to be selected. The heat capacity can be estimated by calculating the volume of the mold and the specific heat capacity of the material, thereby determining the appropriate mold temperature controller(MTC) power.   5. Pump flow and pressure The flow of the circulation pump determines the circulation speed of the heat transfer medium (such as water or heat transfer oil) between the mold and the mold temperature controller(MTC). Insufficient flow will cause uneven mold temperature and affect product quality. Generally speaking, the flow rate is determined according to the size and complexity of the mold. For small molds, a circulation pump flow of 10-30L/min may be sufficient, while a large and complex mold may require a flow of more than 50L/min. The pressure of the mold temperature controller(MTC) must be able to overcome the resistance of the pipeline and the resistance inside the mold to ensure the smooth circulation of the heat transfer medium. If the pressure is not enough, local overheating or overcooling may occur. When selecting a mold temperature controller(MTC), consider the impact of factors such as the mold's pipeline length, pipe diameter, and number of elbows on the pressure. To meet the needs of different molds.   6. Control system Hengde mold temperature controller(MTC) adopts imported microcomputer control mode. According to customer requirements, PLC control and RS485 communication function can be selected to achieve automatic management.   7. Safety Check whether the mold temperature controller(MTC) has perfect safety functions, such as overheat protection, leakage protection, overload protection, etc. For industrial occasions with dangerous environments such as flammable and explosive gases, steam, dust, etc., such as chemical, oil and gas, pharmaceutical and other industries, when purchasing a mold temperature controller(MTC), you also need to consider the explosion-proof function and choose Hengde's explosion-proof mold temperature controller(MTC).   8. Purchase cost / operating cost Compare the prices of mold temperature controllers of different brands and functions. Under the premise of meeting the application requirements, choose the most cost-effective mold temperature controllers(MTCs). At the same time, the operating cost of the mold temperature controller(MTC), including energy consumption, maintenance costs, etc., should also be considered. When purchasing a mold temperature controller(MTC), it is important to choose a manufacturer that offers comprehensive warranty coverage and reliable after-sales support, including timely technical assistance and accessible maintenance services.

With a professional R & D team and excellent after - sales service, we ensure that every customer can make the most of our mold temperature controllers. Now, let's explore the professional debugging process of our mold temperature controllers.   Debugging Steps of the Oil Type Mold Temperature Controller 1. Preparation Before commencing the debugging, ensure the availability of a stable power supply and high quality thermal oil.    2. Power Connection Push the air switch and then turn on the power button. In case the air switch fails to be pushed up, check if the emergency stop button on the controller panel is pressed. If so, rotate the emergency stop button to its normal position. After turning on the power button, if the oil type mold temperature controller alarms, it is likely due to a phase - reversal issue. Immediately turn off the power supply and swap any two of the three incoming power lines. Once the phase - reversal problem is resolved, the controller can start normally.   3. Oil Filling After starting the machine, the oil mold temperature machine will trigger an oil shortage alarm. Gradually add thermal oil, until the entire pipeline is filled with oil and the oil shortage alarm in the oil tank ceases. Be cautious not to over fill the oil tank. As the oil heats up, the tank will release gas. Excessive oil may cause the gas to force the oil out of the tank. After oil filling, carefully inspect all pipelines of the oil mold temperature machine for any oil leaks. Once the pressure shown on the pressure gauge of the oil temperature machine stabilizes, the heating process can be initiated.   4. Heating Set the temperature on the controller for heating. Initially, set the temperature to 90℃ and closely monitor the stability of the pressure gauge. If the pressure gauge remains stable, it is safe to directly set the temperature to the required operating temperature.     Precautions Prior to starting the machine, always double - check whether the emergency stop button on the oil mold temperature controller panel is in the released state. A pressed emergency stop button will prevent the air switch from being closed. During the heating process, if there is a significant difference between the oil outlet temperature and the oil return temperature, with the oil outlet temperature rising rapidly, it is highly likely that the filter is blocked. Before further heating, remove and clean the filter to ensure normal oil circulation. If the oil mold temperature controller alarms for oil - shortage or lack of media, it may be caused by poor contact of the liquid level sensor (the cylindrical tube adjacent to the oil tank). Usually, a slight adjustment of the sensor can solve this problem. If the liquid level alarm function is not required, simply unplug the wire above the sensor.   After the debugging process is completed, it is crucial to record all the debugging parameters and the operating status of the mold temperature controller accurately. Compile these records into a detailed debugging report. Once the oil mold temperature controller is put into formal operation, regular maintenance and inspections should be carried out at fixed intervals. This ensures that the controller always operates in an optimal condition, providing reliable temperature control for your production processes.   At Hengde Company, we not only offer top - tier mold temperature controllers but also comprehensive support throughout the product lifecycle. Our professional team is always ready to assist you, ensuring that your investment in our products brings long - term benefits and efficient production.   Choose Hengde,Choose Perfect Mold Temperature Controller！
