METHOD FOR PRODUCING FINE, HOLLOW PROJECTION TOOL

This method for manufacturing a fine hollow protruding tool (1) involves: a protrusion forming step of bringing a projecting mold part (11) that includes a heating means into contact from one surface (2D) side of a base sheet (2A) including a thermoplastic resin, and, while softening the contact sec...

Zusammenfassung:	This method for manufacturing a fine hollow protruding tool (1) involves: a protrusion forming step of bringing a projecting mold part (11) that includes a heating means into contact from one surface (2D) side of a base sheet (2A) including a thermoplastic resin, and, while softening the contact section (TP) with heat, inserting the projecting mold part (11) into the base sheet (2A), to form a protrusion (3) that protrudes from the other surface (2U) side; and a release step, after a cooling step, of withdrawing the projecting mold part (11) from the interior of the protrusion (3), to form the fine hollow protruding tool (1). In the protrusion forming step, the protrusion (3) is formed by using a first warp-suppressing means that suppresses warping of the base sheet (2A) when the projecting mold part (11) is inserted into the base sheet (2A). In the release step, the fine hollow protruding tool (1) is formed by using a second warp-suppressing means that suppresses warping of the base sheet (2A) when the projecting mold part (11) is withdrawn from the interior of the protrusion (3).
