Heating water type mold heater for PU foam production
In the production of PU foam, the heating water type mold heater, also known as the water-type mold temperature controller, plays a crucial role. Here is an introduction to its application in PU foam production:
Features of heating water type mold heater
Isolated Electric Control Box: The electric control box is isolated from the machine body, which has a good heat insulation effect and can extend the service life of electrical components.
Special Touch Screen Controller: The use of a mold temperature machine - specific touch screen controller makes temperature control more reasonable, and can save more than 35% of electricity.
Stainless Steel Pipeline: The main pipeline is integrally formed of 304 stainless steel, with small pipe loss, uniform heating, and long service life.
Automatic Exhaust Function: It has an automatic exhaust function when starting up, which can remove the air in the pipeline to ensure the normal operation of the system.
Working Principle of heating water type mold heater
It uses water as the heat transfer medium. The heater heats the water to the required temperature, and then the hot water is circulated to the mold through a pump. The temperature probe monitors the temperature in real-time and adjusts it according to the temperature change to ensure that the mold is maintained at a stable working temperature. This can effectively avoid product defects caused by temperature fluctuations.
Advantages of heating water type mold heater used in PU Foam Production
High-precision Temperature Control: It can achieve a temperature control accuracy of ±0.5°C or even higher. In PU foam production, precise temperature control is crucial for the quality and performance of the foam. Stable mold temperature helps to ensure the uniformity of the foam's cell structure, making the density of the foam more consistent and improving the mechanical properties of the product.
Efficient Heat Transfer: Water has a higher heat transfer efficiency than some other heat transfer media. It can quickly transfer heat to the mold, shortening the heating time of the mold and improving production efficiency. At the same time, it can also quickly take away the heat of the mold during the cooling process, helping to speed up the cooling cycle of the mold and further increasing the production speed.
Good Environmental Performance: Water is a natural, environmentally friendly heat transfer medium, which does not cause pollution to the environment like some organic heat transfer oils. In the context of increasingly strict environmental protection requirements, the use of water-type mold heaters is more in line with the development requirements of the industry. Moreover, water sources are easy to obtain, and the operating cost is relatively low.
Stable and Reliable Operation: The water-type mold heater is usually equipped with a perfect safety protection and fault indication system, such as power phase loss protection, pump overload protection, overheat protection, low water level protection, etc. These protection functions can ensure the safe operation of the equipment, reduce the occurrence of faults, and at the same time, the fault indication system is convenient for maintenance personnel to quickly find and solve problems, reducing downtime.
