Hydraulic Press Machine For SMC Auto Shroud FormingUpdate：2022-05-04 Hits：164
FRP shroud, also known as FRP windshield, is an air guide device installed on the top of the cab of a truck or tractor. Its main function is to effectively reduce the air resistance and fuel consumption of the truck at high speed. SMC automotive air shroud is a product processed from glass fiber reinforced plastics and is a new composite material. Four-column hydraulic press machines of 1600 tons, 2000 tons and 2500 tons can be used to form the molded SMC glass fiber reinforced plastic automobile shroud.
Features of hydraulic press machine for SMC automobile shroud forming
1. The SMC auto shroud forming hydraulic press adopts a man-machine interface design, which can lock the process parameters, and the operator cannot modify it without authorization to ensure the quality of the product.
2. The heating plate adopts deep hole processing technology, and the electric heating tube adopts multi-section design. The temperature is evenly distributed on the heating plate, so that the temperature is even and good, and it is equipped with a thermoelectric tube fault display light.
3. The SMC auto shroud forming hydraulic press adopts a digital temperature controller, which can display and control the temperature of each hot plate separately. It has the advantages of intuition, convenient adjustment and energy saving.
4. Adopt fast lifting oil cylinder, fast mold opening and closing speed, improve production efficiency, slow mold clamping to protect mold.
Hot-press forming hydraulic press, composite material forming hot-press forming machine adopts PLC control, easy to operate and adjustable working parameters.
5. The equipment can be equipped with an in-mold core-pulling control system and a preset in-mold ejection control system, which can realize rapid descending, subsection and pressing, subsection deflation, work, pressure maintaining, slow mold opening, and fast mold opening. A series of actions such as return stroke, slow demoulding, rapid ejection, ejection stop, and rapid return, and the temperature can be controlled at multiple points. It is mainly used for integral molding of thermosetting (glass reinforced plastic) plastic products and thermoplastic products, and is suitable for SMC and BMC. , DMC, GMT, etc.
The processing method of SMC glass fiber reinforced plastic automobile shroud is to put a certain amount of molding material into a pair of metal molds, and under a certain temperature and pressure, the molding compound is heated and plasticized in the mold cavity, and it flows under pressure and fills the mold. The cavity is formed by circularization. The compression molding process requires heat and pressure during the molding process, so that the plasticizing of the molding compound produces a flow that fills the mold cavity and causes the resin to undergo a curing reaction. When the composite molding compound flows and fills the cavity, not only the resin flows, but also the reinforcing material, so that the resin and fibers fill all parts of the cavity at the same time.
