In the production process of FRP, a certain amount of molded material is added to the mold heated by the mold temperature machine by the molding molding process, and the mold is continuously heated and solidified under pressure, and finally cooled and demolded. Today, we will introduce you to the FRP mold temperature machine specially developed for the composite materials industry.

The molding process of molded material is a process of physical and chemical reaction, and whether the molding temperature control of FRP molded material is accurate and uniform is directly related to the technical indicators of the molded products. At present, there are problems of poor temperature uniformity and accuracy of mold and long processing cycle in the molding process of FRP molded material. Therefore, on the basis of the circulating heating system, the FRP mold temperature machine suitable for the molding process of molded material is improved and manufactured.
In actual production, the temperature in the middle of the mold will be lower than the expected temperature due to the indirect heating of the upper and lower pressure plates, so it is difficult to meet the requirements of the process. Therefore, the temperature control of the mold temperature machine must be set in strict accordance with the production process and can be kept constant. The key to the heating method of FRP mold temperature machine is to achieve the humidity rate required by the process, and at the same time ensure that the middle temperature of the molded material is uniform, and ensure that the temperature of the upper and lower ends of the molded material is basically the same as the middle temperature.
In order to reduce the temperature difference between the upper and lower end of the mold and the intermediate temperature, in order to achieve the upper and lower pressure plate to control the temperature of the upper and lower end of the mold, the FRP mold temperature machine is usually a double machine in one, and the upper and lower molds are controlled separately, so that the control process is more operable.
