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!

Chillers achieve cooling primarily through the refrigeration cycle, where four key components—compressor, condenser, expansion valve, and evaporator—work in close coordination. Below is a detailed explanation of how chillers create an effective cooling process:   1.Compressor Pressurization The compressor, as the heart of the chiller, plays a crucial role in converting low-temperature, low-pressure refrigerant gas into high-temperature, high-pressure gas. During the compression process, the temperature and pressure of the refrigerant gas both rise. This change in state sets the stage for the subsequent condensation process, as refrigerant gas at higher pressures is more effective at transferring heat to the cooling medium, leading to a phase change.   2.Condenser Heat Exchange Once the high-temperature, high-pressure refrigerant gas enters the condenser, it undergoes heat exchange with the surrounding environment. In air cooled chillers, a fan drives air through the condenser to carry away heat, while water-cooled chillers utilize circulating water to absorb heat. During this process, the refrigerant gas cools down and condenses into a high-pressure liquid. Condensers are typically equipped with high-efficiency heat dissipation devices, such as variable-speed fans or enhanced heat exchange tubes, to improve heat transfer efficiency and speed up the refrigerant condensation process.   3.Expansion Valve Throttling and Pressure Drop When the high-pressure liquid passes through the expansion valve, there is a significant drop in both pressure and temperature. The primary function of the expansion valve is to regulate the flow of refrigerant, ensuring that it can fully evaporate in the evaporator, thereby achieving an effective cooling effect. This flow control is critical for maintaining the stable operation of the refrigeration system and optimizing its cooling efficiency.   4.Evaporator Heat Absorption The low-pressure, low-temperature refrigerant liquid enters the evaporator, where it quickly absorbs heat from the surrounding environment. In practical applications, chillers primarily absorb heat from cooling water, causing the refrigerant to vaporize into a low-temperature, low-pressure gas. During this process, the water inside the evaporator is cooled and then pumped to the equipment or systems that need cooling, transferring the heat and meeting the cooling demands of the system.   Through the continuous cycle of these four steps, chillers can reliably supply low-temperature cooling water to equipment or systems, ensuring stable operation under optimal temperature conditions. Compressor: Increases refrigerant pressure and temperature. Condenser: Dissipates heat, causing refrigerant to liquefy. Expansion Valve: Reduces refrigerant pressure. Evaporator: Absorbs heat, achieving cooling.   In summary, industrial chillers rely on the seamless cooperation of the compressor, condenser, expansion valve, and evaporator, as well as the continuous flow of refrigerant through these components, to achieve cooling. This process ensures the circulation of cooled water for various industrial applications and research experiments, providing reliable cooling support.    Hengde, with years of expertise in the chiller industry, is committed to continually optimizing product performance. Our chillers not only offer high cooling efficiency but are also equipped with intelligent control systems that precisely adjust cooling capacity to meet the diverse needs of different industries.

Hengde Company, a renowned name in the industrial temperature control realm, has been committed to providing high quality mold temperature controllers for years. Our products are widely applied across various industries, characterized by their reliability, precision, and advanced technology. 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！

Industrial chillers are commonly used in modern industrial production to cool machinery and equipment through a circulating cooling water system. Whether an air-cooled industrial chiller can be placed outdoors requires consideration of various factors.   Theoretical and Design Considerations From a theoretical and design standpoint, air-cooled industrial chillers, which use air as the heat exchange medium, can be placed outdoors. Unlike water-cooled chillers, air-cooled chillers' biggest advantage is that they do not require an additional cooling water source, making them ideal for areas where water resources are limited. Air-cooled chillers work by using fans to drive air through the condenser, facilitating the heat exchange between the refrigerant and the outside air. As long as the airflow conditions are good, placing the chiller outdoors can meet its basic cooling needs. For instance, in spacious factory yards, an air-cooled industrial chiller can be placed outdoors, free from obstructions, allowing it to fully interact with the outside air and efficiently dissipate heat.   Challenges of Outdoor Placement However, placing the chiller outdoors comes with several challenges: Environmental Temperature Impact: In extremely high temperatures, the outside temperature may become too high, reducing the temperature difference for heat dissipation, which in turn lowers the cooling efficiency and affects the refrigeration performance. For example, during summer heatwaves, when the outdoor temperature reaches 38°C or higher, the chiller's cooling capacity may significantly decrease. Severe Weather Conditions: Weather events like heavy rain, dust storms, and heavy snow can damage the chiller's electrical components and outer casing. Rainwater could enter the electrical system and cause short circuits, dust may block the condenser fins and reduce heat exchange efficiency, and snow accumulation could damage the chiller's casing. Space and Security Issues: Installing the chiller outdoors requires ample space and additional security measures to prevent theft or vandalism. Noise Considerations: Air-cooled chillers, due to their built-in fans, produce noise during operation. If placed near residential or office areas, especially outdoors, the noise could cause disturbance to nearby residents or employees, impacting their work or quality of life.   Protection Measures for Outdoor Installation If a company decides to place an air-cooled industrial chiller outdoors, several protection measures are necessary. For instance: * Building a Protective Shelter: This shelter can shield the chiller from rain, dust, and direct sunlight while ensuring good airflow. * Installing Wind Shields: To prevent damage from strong winds, protective covers should be installed. * Regular Maintenance and Inspection: After harsh weather events, it’s essential to clean the chiller’s surface, check for debris, and inspect electrical connections to ensure everything is in working order.   Hengde's Air-Cooled Industrial Chillers for Outdoor Use Hengde’s air-cooled industrial chillers are specifically designed with outdoor use in mind.

As a leading supplier of industrial temperature control solutions, Hengde Company has always been committed to providing high - quality and high performance temperature control equipment for various industries. Among many temperature control devices, the mold temperature controller is one of our core products, which is widely used in multiple fields such as plastics, rubber, and die - casting, helping numerous enterprises to improve production efficiency and product quality. Today, let's delve into how to select a suitable mold temperature controller.   In the plastics industry, the mold temperature controller is an indispensable device, playing a crucial role in optimizing the production process and ensuring product quality. 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. Interface size/model: Include the inlet and outlet pipe diameters of the heat medium and the cooling water pipe diameter, etc. These sizes should match the existing pipeline system of the enterprise.   With years of R & D and production experience in the field of mold temperature controllers, Hengde Company can provide you with all - round selection guidance and high quality products.
