Abstract:
1. A facility for using one or more powder materials to produce a solid product having multiple layers, including: a supply of at least one powder material; a die for receiving said powder material and shaping the solid product to be produced, said die secured in a reversible manner to a die-holding table secured to a frame of the facility; an upper punch and a lower punch, wherein said punches are translatable and engage with one another at said die to compress the powder material and produce the solid product; wherein the lower punch is connected to a system of uncoupling members that provide movement of the lower punch, said system being provided with a brake for limiting the travel of said lower punch in the downward direction to keep said lower punch in contact with the powder material contained in the die when producing the solid product having multiple layers to avoid generation of additional compression during the receipt of powder material in the die during intermediate filling phases for each layer of the product; and wherein said system of uncoupling members further comprises an adaptor having a hole, said hole of said adaptor having at least first and second sections, said first and second sections each having a diameter, said diameter of said second section larger than said diameter of said first section, and said lower punch in sliding contact within said first section and having a stop portion at a bottom end, said stop portion having a third diameter greater than said diameter of said first section but smaller than said diameter of said second section.
