Although the press molding is one of the oldest methods of processing in the advanced composite industry, it is still used by many companies for the realization of products in high-volume composite. This process involves the use of mechanical power exercises by an industrial press in order to compress the preform to reach the desired shape. The preform is placed on lower mold part (fixed part), the upper part, is then superimposed, and then the mold is closed. The press applies the mechanical power required to completely fill the mold in which the preform is contained; below the mold, it is placed a tube or vent, which has the task of expelling the excess material from the mold. When you reopen the mold, inside it is the finished product ready for finishing. The pressure molding creates finished products with a high level of resistance and of different thickness depending on the requirements of the customers.
