Abstract: A low-melting adhesive film may include a first adhesive layer made of a material comprising thermoplastic polyurethane, a second adhesive layer made of a material comprising aromatic-based hot-melt thermoplastic polyurethane capable of being applied to low temperature adhesion at a temperature of 60° C. or higher, and a polyethylene (PE)-based protective film layer. The low-melting adhesive film may be used to adhere a carpet fabric to a sound absorbing material and thus produce an integrated sound absorbing and proofing composite carpet.

Abstract: A method of manufacturing a molded product with controlled density may include preparing an upper layer outer sheath and a lower layer outer sheath of the molded product, manufacturing and preparing a filling material which forms a filling layer between the upper layer outer sheath and the lower layer outer sheath, positioning the lower layer outer sheath material in an internal space of a lower mold, disposing a temporary template on an upper portion of the lower mold to seal the internal space, and then injecting the filling material between the lower layer outer sheath material and the temporary template, removing the temporary template, and then positioning the upper layer outer sheath material on the injected filling material of the lower mold, and integrating the upper layer outer sheath material, the filling material, and the lower layer outer sheath material by heating and compression.

Abstract: The present invention relates to a modular clip comprising a clip body having an internally threaded hole formed in its center and two open-ring type elastic members formed integrally with and protruded from both sides of said clip body, respectively. Each of said elastic members has a panel receiving recess formed along the entire length on opposite end portions thereof, respectively. Said elastic members are then extruded outwardly with respect to the main body when structure members mounted to an interior of the automobile and the main body of the modular clip are joined by a screw, and subsequently a circumference of an internally threaded hole formed on the body panel is received in the panel receiving recesses of the elastic members thus easing the mounting of said modular clip to the body panel.
