The first stage: the mold is heated up within a certain period of time to melt the resin in the carbon fiber cloth in the mold.
The second stage: control the mold temperature within a certain temperature so that the resin can fully circulate in the mold.
The third stage: the temperature of the mold is raised to a higher temperature, so that the catalyst in the prepreg, that is, the carbon fiber prepreg, reacts.
The fourth stage: high temperature insulation, during which the resin fully reacts with the catalyst in the carbon fiber prepreg.
The fifth stage: cooling forming, that is, a preliminary forming of carbon fiber products.
During the five deformation processes of compression molding, the control of mold temperature must be precise, and must be carried out according to a certain heating and cooling speed. Too fast or too slow heating and cooling speeds will affect the final quality of carbon fiber products.
The hydraulic press has many advantages such as high speed and high efficiency, energy saving and environmental protection, good flexibility, fast response, high load rigidity, high control power, etc. It is widely used in stamping, die forging, press fitting, straightening, molding and other processes. This machine is mainly used in the molding and pressing process of carbon fiber, glass fiber reinforced plastic, SMC and other molding materials to meet the requirements of the pressing process. The temperature, curing time, pressure and speed of the equipment are all in line with the process characteristics of SMC/BMC materials. It is controlled by PLC, easy to operate, and the working parameters are adjustable.
