Mold temperature controller, 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?   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 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 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 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 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 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. 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 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, 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 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 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, you also need to consider the explosion-proof function and choose Hengde's explosion-proof mold temperature controller.   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. At the same time, the operating cost of the mold temperature controller, including energy consumption, maintenance costs, etc., should also be considered.   For more questions about the purchase of mold temperature controllers, please visit Hengde's website (www.hengdechiller.com).

As a leading player in the industrial temperature control field, Hengde Company has always adhered to the concepts of innovation and top - notch quality, providing advanced and reliable temperature control solutions to customers worldwide. Our water type mold temperature controller machines play a crucial role in industries such as plastics and rubber with their excellent performance and stability. The following will provide you with a detailed introduction to the installation steps of Hengde water type mold temperature controller machines, helping you smoothly complete the installation and commissioning of the equipment and embark on a journey of efficient production.     Installation of the Cold Water Circulation System 1. Connecting the Cooling Water Pipeline First, based on the size of the cooling water inlet and outlet of the water type mold temperature controller machine, select suitable high temperature resistant hot water pipes. These high temperature resistant hot water pipes should have good pressure resistance and corrosion resistance to ensure that there are no leaks or aging issues during the long  term passage of cooling water. Accurately dock the cooling water pipes with the cooling water inlet and outlet of the temperature machine, and use professional pipe clamps or connectors for fastening to prevent loosening during operation.   2. Connect the cooling water outlet of the temperature machine back to the water source or water tower to build a circulation loop. This not only enables the effective recycling of water resources, reduces production costs, but also conforms to the concept of environmental protection. During the connection process, ensure that the slope of the pipeline is reasonable to avoid water accumulation, which may affect the cooling effect.     Installation of the Hot Water Circulation System 1. Connecting the Heat Medium Pipeline Use Teflon tubes or bellows to connect the heat medium outlet of the water type mold temperature controller machine to the mold inlet. Teflon tubes and bellows have good flexibility and high temperature resistance, which can adapt to different installation environments and are not easy to deform or damage at high temperatures. When connecting, pay attention to the pipeline direction to avoid bending or twisting and ensure the smooth flow of the heat medium.   2. Connect the mold outlet back to the heat medium inlet of the temperature machine to form a complete hot water circulation path. During the connection process, carefully check whether the connection is well - sealed to prevent hot water leakage.   3. For the unused heat medium inlets and outlets on the temperature machine, it is highly recommended to connect them with Teflon tubes or bellows. This measure can effectively prevent the situation of hot water spraying out and hurting people due to accidental valve opening. At the same time, in order to further improve energy efficiency and ensure the safety of employees, it is best to wrap the hot water connection pipes with insulation cotton. The insulation cotton can effectively reduce heat loss, lower energy consumption, and avoid employees from being scalded.   If you have any questions during the installation process, please feel free to contact Hengde.
