Tool or tool part, system including such a tool or tool part, method of producing such a tool or tool part and method of molding a product from a pulp slurry

A method of molding a product from a pulp slurry, the method comprising:

• in a first step, providing a pickup tool, for picking up pulp from a pulp slurry, the pickup tool comprising a self-supporting pickup tool wall portion having a product face, for contacting the product, and a back face on the other side of the wall relative to the product face, the pickup tool wall portion presenting pores, which are provided by a plurality of channels extending through the pickup tool wall portion, from the product face to the back face;
• applying a vacuum to the back face of the pickup tool, and
• applying pulp slurry to the product face of the pickup tool;
• in a second step, providing a transfer tool for receiving an amount of pulp from another tool, the transfer tool comprising a self-supporting transfer tool wall portion having a product face, for contacting the product, and a back face on the other side of the wall relative to the product face, the transfer tool wall portion presenting pores, which are provided by a plurality of channels extending through the tool wall portion, from the product face to the back face;
• applying a vacuum to the back face of the transfer tool, and
• applying the pulp slurry to the product face of the transfer tool;
• and
• in a third step, providing a pressing tool for pressing an amount of pulp to form a molded product, the pressing tool comprising a self-supporting pressing tool wall portion having a product face, for contacting the product, and a back face on the other side of the wall relative to the product face, the pressing tool wall portion presenting pores, which are provided by a plurality of channels extending through the tool wall portion, from the product face to the back face, the pressing tool forming part of a pressing arrangement comprising a male pressing tool and a female pressing tool;
• applying a vacuum to the back face of at least one of the male or female pressing tool,
• applying the pulp slurry to the product face of the male pressing tool or of the female pressing tool,
• heating at least one of the male or female pressing tool, and
• forcing the male pressing tool and the female pressing tools towards each other, such that the pulp slurry is pressed between product faces of the respective tool.
