Hydraulic Press Machine for FRP Automotive Bumper & Shroud Molding
Following are the process details of hydraulic press machine for FRP automotive bumper and shroud molding:
1. Calculation of charging amount
According to the specifications and dimensions of the product, the amount of molded raw materials used is calculated to ensure the accuracy of the weight and size of the product.

2. Brush the mold release agent on the surface of the mold
In order to ensure the appearance quality of the product, it is necessary to brush a layer of special release agent on the surface of the mold during production; For example, when making FRP centrifugal fan accessories for hand lay-up, a layer of demoulding wax is brushed on the mold.
3. Preheat the molded raw materials
Since the molded raw materials are made in advance, it is necessary to apply an oven or infrared lamp to bake the raw materials before use. After the raw material is preheated, the manufacturing method can be used to reduce the filling device of the mold and improve the work efficiency.

4. Calculation of product pressure value
On the horizontal plane, the pressure per unit area is called the product pressure value, and the pressure value is different for different types of molded products. 5. Pressing and molding
● Install the corresponding metal parts, which are used to improve the strength of the product or play a connecting role;
● According to the calculated loading amount, the molding raw materials can be added to the charging chamber of the 2000-ton four-column hydraulic press;
● After the raw materials are added, the process of extrusion of the raw materials under pressure is called closed mold, and the extrusion accessories should be appropriately slowed down after contact with the raw materials, so as to ensure that the gas inside the mold is completely discharged;
● Heating and curing
The curing of the molded raw material is promoted by heating, and the heating time and temperature are related to the type of raw material
If the heating time is too short, it may cause the product to cure incompletely; Heating time too long will cause the product to become brittle, affecting the work efficiency;
● Cooling out of the mold
After the raw materials that are fully cured after heating are cooled, the product in the mold can be removed;
● Processing
The molded products are polished, turned, drilled, polished and other processes according to the requirements.
