Product Description

BMC material pressing refers to the process of plasticizing the molding material under hot pressing and filling the cavity to form. When the BMC material is heated by the press mold, the resin softens and melts, so that the molding material has fluidity, and starts to flow and fill the cavity under the pressure of the press. At this time, the resin in the BMC material undergoes a chemical reaction and gradually becomes a hard solid which is insoluble and infusible. The BMC material exhibits a low-molecular viscous flow state after heating, and has good fluidity. At the same time, a functional group cross-linking reaction occurs, the molecular weight increases, and a partial network structure appears. At this time, the fluidity becomes small and begins to exhibit a certain elasticity, actually It is in a so-called gel state. Further heating, the crosslinking reaction proceeds, the crosslinking density increases, and the resin is converted into a hard bulk structure. If the molding material has filled the cavity before this, a qualified article can be made. BMCc injection mould
