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).

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?
