摘要： In this molded surface fastener, an engaging element includes a columnar stem portion, and micro pawl portions protruding outward from an upper end outer peripheral edge of the stem portion in a plan view of the engaging elements. A pawl width dimension of the micro pawl portions is smaller than a line segment connecting two points on the upper end outer peripheral edge of the stem portion. The micro pawl portions protrude toward a base portion. This molded surface fastener has a high peel strength and a shear strength with respect to a female surface fastener.

摘要： This manufacturing method of a molded surface fastener involves a primary molding step for forming a primary molded body and a secondary molding step for compressing a provisional element of the primary molded body while heating the same. A molding apparatus is provided with a mold member comprising multiple penetration holes and multiple concave portions, whereof each penetration hole communicates to at least one concave portion; in the primary molding step, the molding apparatus is used to form a primary molded body comprising a provisional element having a primary stem portion and a pawl portion is formed from the protruded portion by compressing the provisional element. By this means, it is possible to stably manufacture a molded surface fastener that has an engaging element comprising a pawl portion that projects from the outer peripheral edge of an engaging head portion.
