Latest Patents

One of Oono's latest patents is an apparatus for forming patterns onto articles during injection molding. In this method, after the pattern-bearing film is fed to the female mold, the distal end of the film is fixed under a lower portion of the female mold. At the same time, the film is retreated by a force from the film supply portion. This process tightens the film, preventing slacks or wrinkles from forming. Consequently, the film can be effectively spread around the parting surface of the female mold. The apparatus features a film suppressing frame that is pressed to the female mold through a sliding rod arranged within the mold, allowing for accurate positioning of the film. Additionally, the film suppressing frame is designed to advance and retreat from the female mold, optimizing the space around the apparatus.
