Mold temperature controllers (MTCs) are essential pieces of equipment in industries such as plastics, rubber, die-casting, and injection molding. These devices are designed to regulate the temperature of molds during the manufacturing process, ensuring optimal product quality and production efficiency. The importance of maintaining the correct mold temperature cann't be overstated, as it directly impacts the precision and consistency of the final product.     Functionality of Mold Temperature Controllers Mold temperature controllers serve several key functions, all geared towards improving the efficiency of industrial molding processes:   1. Precise Temperature Control: The primary function of an MTC is to maintain a stable, uniform temperature in the mold. In the manufacturing processes such as injection molding, blow molding, and die - casting, the temperature of the mold has a significant impact on the performance of the production process and the quality of the final product. For example, in injection molding, if the mold temperature is too low, the plastic melt may cool down too quickly, resulting in uneven filling of the mold cavity, short shots, and poor surface quality of the product. On the contrary, if the mold temperature is too high, it may cause over - heating of the plastic, leading to material degradation, warping, and other defects. A mold temperature controller can accurately adjust the temperature, usually within a very small temperature deviation range (such as ±0.5°C or even smaller), ensuring that the mold temperature remains at the optimal value required by the production process.   2. Heating and Cooling: An MTC provides both heating and cooling functions. By regulating the temperature of the mold, it ensures that the material doesn't cool too quickly, preventing issues such as warping or cracks. On the other hand, it also prevents overheating, which can result in defects like flash or uneven surface quality.   3. Consistency and Quality: Mold temperature controllers help ensure consistent temperatures across the entire mold surface. This consistency reduces the likelihood of defects and variability, resulting in higher-quality products with fewer defects, which is critical in industries where precision is vital.   4. Energy Efficiency: Modern mold temperature controllers are designed to be energy-efficient, minimizing energy waste by adjusting the heat and cooling cycles in real-time. This contributes to lower operational costs while maintaining production speed and quality.   5. Faster Production Cycles: By keeping the mold temperature under control, MTCs help to speed up production cycles. A stable temperature reduces the need for constant adjustments, allowing for faster and more consistent output, which is a significant advantage in high-volume manufacturing environments.   6. Cost Reduction: By preventing common molding problems, such as warping or dimensional changes, mold temperature controllers help to reduce scrap and rework. This not only improves product quality but also cuts down on material costs and production downtime.   Why Choose Nanjing Hengde Electrical Equipment Co., Ltd?

Temperature Range Different mould temperature controller machines have different temperature requirements. Therefore, it is necessary to choose heat transfer oil that can meet these temperature needs. Generally speaking, the higher the temperature of the mould temperature controller machine, the lower the viscosity of the heat transfer oil; conversely, the lower the temperature of the mould temperature controller machine, the higher the viscosity. Thus, when selecting heat transfer oil, it is essential to ensure that its viscosity matches the temperature of the mould temperature controller machine.   2. Performance of Heat Transfer Oil The key performance indicators of heat transfer oil include high-temperature resistance, viscosity, flash point, carbon residue, acid value, and moisture content, etc. Ensure that the selected heat transfer oil can withstand the operating temperature of the mould temperature controller machine and has a long service life. High quality heat transfer oil should have a high thermal conductivity coefficient, good thermal stability, and a long service life. These properties can ensure that the heat transfer oil is not easily decomposed or oxidized at high temperatures, thereby extending the service life of the mould temperature controller machine.   3. Environmental Performance of Heat Transfer Oil Nowadays, more and more enterprises pay attention to environmental protection. Therefore, it is also necessary to choose environmentally friendly heat transfer oil. Environmentally friendly heat transfer oil is friendly to the environment, does not produce harmful substances, and is in line with the current trend of green environmental protection.   4. Price of Heat Transfer Oil The prices of heat transfer oils of different brands and models vary. Generally speaking, high quality heat transfer oil is more expensive. Therefore, when selecting heat transfer oil, on the premise of ensuring performance and environmental performance, try to choose heat transfer oil with a reasonable price. At the same time, choose brands with a good reputation to ensure that their quality and performance meet relevant industry standards and certification requirements.   In conclusion, when selecting heat transfer oil for injection molding dedicated mould temperature controller machines, multiple factors such as the temperature range, performance, environmental performance, and price should be comprehensively considered to select the most suitable heat transfer oil. Hengde Company is committed to providing customers with professional solutions and high-quality mould temperature controllers. Additionally, pay attention to choosing a regular heat transfer oil supplier to ensure that the purchased heat transfer oil is of reliable quality and reasonable price. For example, ESSO 50, Mobil 603, and Mobil 605 are all good choices. Oils cannot be mixed, as this will create sludge and cause blockage. Please replace the circulating oil regularly. If the unit is used at temperatures above 150°C for extended periods, check the oil every three to six months and replace it based on the actual situation. When replacing the circulating oil, be sure to prevent water or foreign objects from entering the tank.   Choose Hengde, Choose Perfect Mold Temperature Controller!

Hengde Company, a renowned enterprise in the industrial temperature control field, has been committed to the research, development, and production of high performance mold temperature controller equipment. Our products, including both water mold temperature controller machines and oil mold temperature controller machines, have been widely used in various plastic and rubber processing industries, providing reliable temperature control solutions for our customers. When it comes to the rubber injection molding process, the choice between an oil mold temperature controller machine and a water mold temperature controller machine is a common concern. In fact, both oil mold temperature controller machines and water mold temperature controller machines belong to the category of mold temperature machines, and the fundamental difference between them lies in the heat transfer media they use. Water mold temperature controller machines use water, while oil mold temperature controller machines use heat conducting oil. In the rubber injection molding process, each has its own advantages and disadvantages, and the choice of which equipment to use mainly depends on specific production requirements and conditions.   1.Operating Temperature Oil mold temperature controller machine: Oil mold temperature controller machines can provide a much higher operating temperature, usually reaching 300℃, 350℃ or even higher. For some rubber materials that require high temperature injection molding, such as certain special type rubbers, oil mold temperature controller machines can meet their processing temperature requirements. This ensures that the rubber materials are fully melted, achieving good fluidity, which is convenient for filling the mold cavity and thus obtaining high quality rubber products.   Water mold temperature controller machine: The operating temperature of water mold temperature controller machines is generally below 180℃. If the temperature required for the rubber injection molding process is within this range, water mold temperature controller machines can be applied. For the injection molding of ordinary rubber materials, water mold temperature controller machines can provide stable temperature control to ensure product quality.   For example, a customer's PP material has a molding temperature range of 160℃ - 220℃, and the mold temperature needs to be kept constant within this range during the molding process.Since the heating range exceeds 180℃, a water mold temperature controller machine is unsuitable. An oil mold temperature controller machine is recommended.   2.Heat Transfer Efficiency Oil mold temperature controller Machine: The specific heat capacity of oil is relatively smaller than that of water. However, at high temperatures, the heat transfer performance of oil is stable, and it will not generate a large amount of steam like water at high temperatures, which could lead to pressure problems. In injection molding processes that require rapid heating or cooling, oil mold temperature controller machines can transfer heat to the mold more quickly, improving production efficiency.   Water mold temperature controller machine: Water has a large specific heat capacity. Under the same temperature change, it can absorb or release more heat. In injection molding processes with a small temperature variation range, water mold temperature controller machines can utilize this characteristic to control the mold temperature more stably, with relatively small temperature fluctuations.   3.Safety Oil mold temperature controller machine: Oil is a flammable substance. When using an oil mold temperature controller machine, fire prevention measures need to be taken. Open flames should be avoided around the equipment, and corresponding fire extinguishing equipment should be equipped. At the same time, the sealing requirements of oil mold temperature controller machines are relatively high to prevent oil leakage from triggering safety accidents.   Water mold temperature controller machine: Water is non flammable. Compared with oil - temperature machines, water mold temperature controller machines are safer. In some production environments with strict fire prevention requirements, water mold temperature controller machines are a more suitable choice.   4.Cost Oil mold temperature controller machine: The price of oil is relatively high, and it needs to be replaced after a period of use, increasing the operating cost. In addition, the maintenance cost of oil temperature machines is also relatively high. The heating system, circulation system, and other components need to be regularly inspected and maintained to ensure the normal operation of the equipment.   Water mold temperature controller machine: Water is low cost and easily accessible. The maintenance of water mold temperature controller machines is relatively simple, mainly inspecting and maintaining components such as pipelines and water pumps, and the operating cost is low.   In summary, if the rubber injection molding process requires high temperatures, has requirements for heating speed, and can meet the safe use conditions of oil temperature machines, then an oil mold temperature controller machine may be more suitable. Because heat conducting oil is used as the heat transfer medium, it has excellent thermal stability, and the temperature control range is from room temperature to 400℃, which can meet the heating needs of various high temperature materials. If the molding temperature is within the operating temperature range of a water mold temperature controller machine, and there are strict cost  control requirements while pursuing high safety, a water mold temperature controller machine is a better choice. Because the temperature control range of a water mold temperature controller machine is from room temperature to 180℃, and it uses clean water resources as the heat transfer medium, which is clean, environmentally friendly, and pollution free. Coupled with the excellent heat conduction performance of water, it can heat the mold very quickly. Equipped with a PID ± 1℃ intelligent temperature controller, it can fully meet the requirements of the injection molding process.     In actual injection molding process production, since the heat required temperature of most injection molding materials is below 180℃, many manufacturers choose to use water mold temperature controller machines as auxiliary temperature control equipment for the injection molding process, and relatively fewer use oil mold temperature controller machines. Overall, whether to choose an oil mold temperature controller machine or a water mold temperature controller machine should be compared according to the actual situation. Hengde Company always provides professional advice and high quality products to help customers make the most suitable choice for their production processes.   Choose Hengde, Choose Perfect Mold Temperature Controller!

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！

Currently, the most commonly used mold temperature controllers in the plastics industry are mainly divided into two types: water type mold temperature controllers and oil type mold temperature controllers.   Water type Mold Temperature Controllers Water type mold temperature controllers use water as the heat medium and usually operate based on the principle of direct heating and cooling. Their common temperature ranges are three types: below 100°C (212°F), 120°C (248°F), and 180°C (356°F). Water, as a heat medium, has advantages such as low cost and no pollution, and is widely used in some production scenarios where the temperature requirements are not particularly high.   Oil type Mold Temperature Controllers Oil type mold temperature controllers use professional industrial oil that is not easily decomposed by high temperatures as the heat medium and work based on the principle of direct heating and indirect cooling. The commonly used temperature ranges by manufacturers are generally below 180°C (356°F), 200°C (392°F), and 300°C (572°F). Oil - type mold temperature controllers can reach higher temperatures and are suitable for production processes with high temperature requirements.   Application Advantages of Mold Temperature Controllers Accelerate the production process: By precisely controlling the mold temperature, the product molding cycle can be shortened, the production progress can be accelerated, thereby reducing production costs and minimizing the loss of production materials. Improve product quality: Effectively reduce the proportion of unqualified products, strictly control product quality, and ensure that products meet high - quality standards. Precise temperature control: The temperature can be controlled within the set range, so that the appearance quality of products can be strictly controlled, enhancing the aesthetics and market competitiveness of products. Increase production efficiency: Increase the molding time of neutral products, significantly improve production efficiency, and create more economic benefits for enterprises.   Selection Suggestions Water quality consideration: If the pH value and iron content in the water of the manufacturer's location are too high, or the water is not clean with too many impurities, it is not recommended to use a water - type mold temperature controller. Instead, an oil - type mold temperature controller should be selected to avoid equipment failures due to water quality problems. Product characteristics: If the products produced by the manufacturer are transparent or optical mirror products, since oil mist may affect the gloss of the products, it is not recommended to use an oil - type mold temperature controller. A water - type mold temperature controller is more suitable.   Important Technical Parameters to Pay Attention to When Purchasing Temperature control range: Refers to the maximum temperature control range that the mold temperature controller can achieve, and it needs to be selected according to the temperature requirements of the production process. Temperature control accuracy: That is, the temperature deviation of the mold temperature controller during stable operation. The higher the accuracy, the more beneficial it is to the control of product quality. Power supply and power data: Include the total power of the mold temperature controller, the power of the main components, the supply voltage, and frequency. These data are related to whether the equipment can operate normally under the existing power conditions of the enterprise. Heat transfer medium: Currently, the commonly used ones are heat - conducting oil and water, and it needs to be determined according to actual production needs and the above - mentioned selection suggestions. Cooling method: Oil - type temperature controllers use indirect cooling, and the commonly used cooling methods for water - type temperature controllers are direct cooling and indirect cooling. Different cooling methods are suitable for different production scenarios. Heating power: That is, the maximum heating power of the mold temperature machine, which determines the heating speed of the equipment. Circulating pump power: Involves the power specifications, size, and parameters of  the pump, affecting the circulation efficiency of the heat medium. Flow rate and pressure: It is necessary to ensure that the heat medium has sufficient flow rate and pressure to meet the heat exchange requirements and ensure the temperature control effect.
