Dual-temperature mold temperature controllers, also known as dual-unit integrated mold temperature controllers or dual-circuit mold temperature controllers, are characterized by having two independent temperature control systems inside. This unique design enables them to meet different temperature control requirements simultaneously. For example, in the production processes of magnesium-aluminum alloy die-casting, SMC (Sheet Molding Compound), and BMT (Bulk Molding Compound), they can precisely control the temperatures of the upper and lower molds respectively, effectively suppressing product defects, reducing the generation of defective products, and improving the molding efficiency of products.
In terms of working principle, dual-temperature mold temperature controllers mainly operate based on the principles of heat conduction and heat convection. Taking the dual-temperature oil-type mold temperature controller as an example, it heats the heat transfer oil through heating elements such as electric heating tubes to increase its temperature. Then, the hot oil pump forcibly circulates the high-temperature heat transfer oil into the heating channels of the mold. Heat is transferred to the mold through heat conduction and convection to achieve the heating of the mold. When it is necessary to lower the mold temperature, the cooling system is activated, and cooling water or other cooling media conduct heat exchange with the high-temperature heat transfer oil through the heat exchanger to take away the heat of the heat transfer oil, thus reducing the mold temperature.
In terms of performance, dual-temperature mold temperature controllers have outstanding performance:
- High-precision Temperature Control: Adopting intelligent temperature control systems, the temperature control accuracy can be as high as ±0.5 °C or ±1 °C, or even higher, ensuring that the mold maintains a constant temperature during the processing process and greatly improving the processing accuracy and surface quality of the mold.
- Rapid Response: With advanced heating and cooling systems and optimized temperature control algorithms, dual-temperature mold temperature controllers can reach the set temperature in a short time, quickly adapt to temperature changes during the production process, and ensure the stability and quality of product molding.
- Stable and Reliable: High-quality mechanical and electrical components are selected. The equipment has a simple structure and is convenient for maintenance. It can maintain stable performance during long-term production, reducing failures and downtime.
- Energy-saving and Environmentally Friendly: By precisely controlling the mold temperature, it reduces material waste and energy consumption. Meanwhile, it adopts energy-saving designs, such as high-efficiency heating elements and optimized cooling systems, further reducing energy consumption and meeting the requirements of sustainable development in modern industry.
- Multifunctionality: Equipped with multiple practical functions such as a constant temperature function, heating power switching function, and timed shutdown function. It also supports the use of external cooling water or water tanks, enabling it to adapt to different production needs and improving production efficiency and flexibility.
- Intelligent Management: Using microcomputer or PLC control technology, it can communicate and exchange data with the host computer through interfaces such as RS485 communication function to realize remote monitoring and automated management, making temperature control more precise and efficient and reducing the costs and risks of manual intervention.
- High Safety: Equipped with pipeline explosion-proof devices, safety protection systems and other safety devices, and adopting an isolated electrical control box design, it effectively prevents safety accidents and prolongs the service life of electrical appliances.
The application range of dual-temperature mold temperature controllers is quite extensive, covering many industries such as hot pressing molding, automotive interior parts, die-casting mold temperature control, zinc-magnesium-aluminum alloy die-casting, and chemical reaction kettles. Its advantages lie not only in being able to meet the strict requirements of temperature control in complex production processes but also in being able to save equipment costs and space occupation for enterprises. Compared with two traditional independent mold temperature controllers, the dual-temperature mold temperature controller integrates two sets of temperature control systems into a compact frame, with a more beautiful appearance and a smaller footprint, greatly optimizing the utilization of production space and reducing the equipment procurement and operation costs of enterprises.
Currently, there are numerous manufacturers of dual-temperature mold temperature controllers in the market, such as Nanjing Ouno Intelligent Equipment Co., Ltd. and Nanjing Oune Machinery Co., Ltd. These manufacturers are constantly increasing their investment in research and development, striving to improve the performance and quality of dual-temperature mold temperature controllers and provide users with more reliable, efficient products and perfect after-sales services. For example, the dual-temperature water-type mold temperature controller of Ouno Intelligent adopts intelligent heating and cooling devices, non-standard customization, and heat preservation design for power saving. It can adjust parameters such as size, power, and temperature range according to customer needs, and is also equipped with a one-year warranty and lifetime maintenance services, relieving users of their worries.
With the continuous development of industrial production and the increasing progress of technology, dual-temperature mold temperature controllers, as an important industrial temperature control equipment, are being widely used and recognized in more and more fields by virtue of their unique advantages and excellent performance, playing an important role in promoting the high-quality development of industrial production. It is believed that in the future, dual-temperature mold temperature controllers will continue to innovate and upgrade, bringing more surprises and possibilities to industrial production.
