  • Publication number: 20170095946
    Abstract: The method of manufacturing a mold includes the steps of: forming a silicone resin film on a surface of a model having a protrusion pattern; pressing a side of a base plate with which a separation sheet is in close contacts on a gap adjustment mechanism and the silicone resin film; heating and curing the silicone resin film to form the mold; releasing the base plate; and releasing the separation sheet from the mold, after releasing the mold from the model, wherein the gap adjustment mechanism has a height at which a tip of the protrusion pattern sticks into the separation sheet when the base plate is pressed on the gap adjustment mechanism. The method of manufacturing a pattern sheet uses the mold.

  • Publication number: 20150238413
    Abstract: A method is provided which enables a drug to be concentrated at needle-like protruding portions and which further allows transdermal-absorption sheets to be manufactured at high production efficiency. The method repeats a step of feeding a drug-containing solution from a liquid feeding apparatus to a mold and filling needle-like recessed portions with the drug-containing solution through a nozzle aligned over the needle-like recessed portions in a state where the nozzle and a front surface of the mold are brought into contact with each other, and a step of moving the liquid feeding apparatus relative to the mold in a state where the nozzle and the front surface of the mold are brought into contact with each other. Thus, the two-dimensionally arranged needle-like recessed portions are filled with the drug-containing solution.
