Mold Temperature Controller

Selecting an appropriate roller mold temperature controller can be a daunting task for numerous users. An incorrect choice often leads to a host of issues, such as subpar temperature control, insufficient power, an ill - configured circulation pump, and a mismatched expansion tank. Today, we'll explore how to communicate effectively with suppliers of roller mold temperature controllers to ensure a precise and suitable selection.   1. Gain an In - Depth Understanding of the Roller Structure Before making a decision on a roller mold temperature controller, it's essential to have a clear comprehension of the roller structure. In the current market, the prevalent roller structures are hollow rollers and sandwich rollers. Irrespective of the type, when choosing a roller mold temperature controller, providing the supplier with accurate diameter and length data of the roller is crucial. These figures are instrumental in precisely calculating the volume of heat transfer oil required, which in turn helps determine the proper heating power. For instance, a roller with a larger diameter and greater length demands more heat transfer oil, thus necessitating a corresponding increase in heating power.     2. Thoroughly Consider the Height of the Composite Roller from the Ground The height of the composite roller from the ground is a significant factor in the selection of a roller mold temperature controller. When communicating with suppliers about the selection process, providing detailed information about this height enables the manufacturer to recommend either an oil temperature controller with an external oil tank or one with an internal oil tank, based on the actual situation. The difference between an internal and external oil tank setup should not be overlooked, as it directly impacts the convenience and comfort during subsequent usage. If the height from the ground is not suitable and the oil tank's position is ill - placed, it can pose numerous challenges during operation and maintenance.   3. Furnish Comprehensive Production Process Information A complete and accurate account of the production process is the linchpin in choosing the right roller mold temperature controller. For example, you need to clearly communicate to the manufacturer details such as the specific materials processed by the composite roller, the water content of those materials, and whether cooling is required during the production process. By providing this information in advance, the supplier can make customized selections tailored to your unique requirements, ensuring that the chosen roller mold temperature controller meets all production needs. For example, when processing materials with high water content, the roller mold temperature controller may need to have enhanced cooling capabilities.     In summary, when choosing a specialized roller mold temperature controller, it's necessary to calculate key parameters like heating power meticulously, based on actual production process requirements. Additionally, pay attention to details such as the compatibility of the pump flow rate and the appropriate size of the expansion tank. Information such as the roller's diameter, length, interface size, and the height of the rotary joint from the ground are all critical aspects to consider during the selection. Moreover, it's important to ascertain whether the roller is jacketed or hollow, its volume, or the diameter and length of the coil. Also, clarify how long it takes to heat the roller to a specific temperature, whether cooling is needed, and the specific heating temperature and time requirements. These are mainly determined by production capacity, that is, the weight of products produced per hour, along with the maximum temperature, the temperature to be maintained, and the product type. When determining the heating power according to roller specifications, the roller's weight is a primary consideration, and understanding the preheating time is essential. Since the roller is a fixed heating object, if possible, extending the preheating time can be beneficial. Additionally, the option of heating power group switching allows for flexible adjustment according to actual needs.   These are the key questions typically asked by roller mold temperature controller suppliers. By being aware of these technical parameters in advance, you can provide accurate information to the supplier in one go when sending an inquiry, avoiding the time - consuming process of repeated information confirmation during back - and - forth communication. We hope these tips will be of great assistance when you're in the market for a roller mold temperature controller.   Choose Hengde，Choose Perfect Mold Temperature Controller！

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.

Hengde mold temperature controllers are widely utilized in a diverse range of industries. 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!
