Various embodiments include a male surface fastener member configured for being molded onto a surface of a foaming resin mold body. The male surface fastener member includes a plurality of male surface fastener strips connected with each other in an end-to-end relationship via a connecting portion that is integrally formed with at least the end portions of each male surface fastener strips. Each male surface fastener strip includes a base material having a first surface from which a plurality of engaging elements extend upwardly and first and second substantially lateral resin intrusion prevention walls that upwardly from the first surface along a width direction of the base material between the first and second longitudinal resin intrusion prevention walls. Each of the lateral resin intrusion prevention walls comprises a plurality of engaging elements that are arranged in series in a width direction of the first surface.

Various embodiments of a mold assembly system include a mold defining at least one trench along a surface of the mold and two or more hook fastener elements disposed on the surface of the trench in an end-to-end relationship. Each hook fastener elements includes: (1) an elongated base, (2) a plurality of hooks extending upwardly from an upper surface of the base, and (3) a magnetic material disposed within the base. The hook fastener elements are unattached to each other and are separately disposed within the trench, and the magnetic portion of the trench is configured to attract the hook fastener elements toward the magnetic portion and hold the hook fastener elements adjacent thereto in an end-to-end relationship substantially along the length of the trench. In one embodiment, the hook fastener elements are substantially the same length and are usable in straight trenches, curved trenches, or trenches having various lengths.

Systems and methods of installing hook fastener elements in a mold assembly

A drilling apparatus, in which a hole and an insertion hole for a drilling rod are formed at a drilling position of a table and at a sheet pressing member capable of approaching or leaving a surface of the table, respectively, the drilling rod made of metal, capable of rotating at high speeds and reciprocating vertically are inserted through the both holes, the drilling rod has smooth peripheral and front end faces composed of at least part of a circular section having no blade, and a predetermined clearance is provided between the diameters of the hole and the insertion hole and the diameter of the drilling rod, whereby by pressing the drilling rod rotating at high speeds to the sheet, a sheet material is melted by frictional heat so that a beautiful hole is formed.
