Abstract

In this study, the effects of process conditions of wet pulp mold manufacturing on the properties of the pulp mold were analyzed with a pilot wet pulp mold simulator. Two kinds of pulp stock, HwBKP and ONP pulp, were used in this study. The mesh hole size of the forming wire and the stock concentration were also changed. The results showed that the higher stock concentration led to a higher grammage pulp mold. The ONP pulp stock resulted in a lower grammage pulp mold which could be originated from the lower freeness of the ONP pulp. The grammage of pulp mold was not significantly affected by the mesh hole size of the forming wire. However the mesh hole size had influence on the pulp mold bulk was and the smaller hole size of the mesh resulted in the higher bulk of the pulp mold, which could be caused by changes in the retention of the small components such as ash.
