The process of composite material prepreg molding involves placing the pre treated molding material into a preheated mold and applying high pressure to fill the mold cavity. And gradually solidify the molded material under certain pressure and temperature.
 
The temperature control process of the pre impregnated material molding mold temperature machine mainly includes two aspects: preheating of the molding material and temperature control of the molding process.

1、 Preheating of molding material
 
Before pressing, using a mold temperature machine to preheat the molded material, remove moisture and other volatile components, can improve the curing rate and prolong the pressing cycle; Improve the average solidification of products, enhance the physical and mechanical functions of products, and improve the activity of molding materials.
 
2、 Molding temperature control
 
In the molding process, the role of the mold temperature machine mainly includes controlling the mold installation temperature, heating rate, molding temperature and insulation control, and cooling and cooling processes.
 
1. Temperature control during mold installation
 
The mold installation temperature refers to the temperature required by the mold when placing the material into the mold cavity, and it mainly depends on the type of material and the quality objectives of the molded material. Normally, when the volatile content of the molding material is high and the insoluble resin content is low, the molding temperature is lower. On the contrary, it is necessary to increase the mold installation temperature appropriately. The temperature for molding complex and large products should be within the range of room temperature to -90 ℃.
