Abstract

The present invention relates to a method of producing mold parts (5) on a string molding apparatus comprising a molding chamber (1) between a squeeze plate (2) and a pivoted squeeze plate (3) in which both the squeeze plate (2) and the pivoted squeeze plate (3) can move in a direction towards each other and a direction away from one another comprising the steps of introducing a compressible particulate molding material (4) in the molding chamber (1) and then squeezing the molding material (4) by moving the squeeze plate (2) and the pivoted squeeze (3) towards one another wherein the velocity of the squeeze plate and the velocity of the pivoted squeeze plate are controlled independent from one another during the squeezing of the mold part (5). Further the invention relates to a string molding apparatus for producing mold parts (5) comprising a molding chamber (1) between a squeeze plate (2) and a pivoted squeeze plate (3), in which mold parts (5) are produced by introducing a compressible particulate molding material (4) in the molding chamber (1) and then moving the squeeze plate (2) and the pivoted squeeze plate (3) towards each other to squeeze the mold part (5) wherein the velocity of the squeeze plate (2) and the velocity of the pivoted squeeze plate (3) are controlled independently from one another during squeezing of the mold part (5).
