In many product lines, molding technology is a kind of molding technology that we often use. This process is to add a certain amount of molding materials (premix or prepreg, etc.) into the metal pair mold, and then heat and pressurize them for curing. It is the oldest and most active molding method in the production of composite materials.
BMC insulation is a kind of thermosetting reinforced plastics. For thermosetting plastics, the mold should be preheated to the required temperature before molding. The actual temperature is related to the type, formula, shape and wall thickness of the products, molding equipment and operating environment of the pressed BMC insulation.
Since the curing time of general BMC insulation at 150 ℃ is less than lmin / mm, the feeding should be rapid. For example, if the material is weighed manually, it is not conducive to the improvement of production efficiency due to the slow speed. Therefore, when pressing small products, the mold with a common feeding room is used.
For the products with complex shape, the materials can be pre pressed into the blank similar to the products, so as to avoid the problems of lack of materials or melting line on the protruding parts of the products.
The company's special formula can be used for injection molding. Each formula is specially customized according to your needs to perfectly meet your requirements for product performance and processing performance.
