La présente invention concerne un procédé de forgeage et un appareil de forgeage, susceptibles de mouler simultanément deux produits à l'avant et à l'arrière de matériaux et de ce fait d'augmenter la productivité du moulage par compression, la présente invention comprenant : une presse ayant des moules supérieur et inférieur; un moyen d'alimentation en plaques de plateau pour introduire, au niveau de la partie centrale supérieure du moule inférieur, des plaques de plateau pouvant être mobiles verticalement d'un côté à l'autre à concurrence d'un pas et être éloignées du côté supérieur du moule inférieur; une unité de perforation disposée sur un côté des moules supérieur et inférieur de façon à perforer en continu des parties de trou de fixation de matériau dans les plaques de plateau; un moyen d'alimentation en plaques de matériau disposé à l'avant de l'autre côté de l'unité de perforation de façon à introduire des plaques de matériau, à concurrence d'un pas, sous les parties de trou de fixation de matériau des plaques de plateau et, en même temps, à former des parties saillantes de pénétration, qui pénètrent dans les parties de trou de fixation de matériau, sur la partie centrale supérieure de la plaque de matériau dans chaque pas, qui est déplacée à concurrence d'un pas; une unité de découpe et de fixation par compression disposée sur les moules supérieur et inférieur de l'autre côté de l'unité de perforation de manière à découper les plaques de matériau, qui sont insérées dans les parties de trou de fixation de matériau des plaques de plateau, à concurrence d'un pas et, en même temps, permettent aux parties saillantes de pénétration formées au centre des matériaux découpés de pénétrer dans les parties de trou de fixation de matériau, ce qui permet de les comprimer; et une unité de moulage par compression prévue sur les moules supérieur et inférieur sur l'autre côté de l'unité de découpe et de fixation par compression de façon à mouler par compression les matériaux en cours de transfert.
