The dual molded lens element includes a light transmitting portion and a light absorbing portion, wherein the light transmitting portion includes an optical effective region and a lens peripheral region, and the lens peripheral region surrounds the optical effective region. The light absorbing portion surrounds the optical effective region. The light transmitting portion and the light absorbing portion are made of different plastic materials with different colors, and are integrally formed by an injection molding. The light transmitting portion or the light absorbing portion includes a plurality of annular convex structures, and the annular convex structures surround the central axis.

An acoustic attenuation panel includes a cellular structure including a plurality of acoustic cells separated from one another by peripheral partitions, a perforated acoustic structure, the perforated acoustic structure and the cellular structure being formed in one piece in a first material, and a porous acoustic layer formed of a second material and fastened to a surface of the perforated acoustic structure by entangling the first material and the second material.

According to one embodiment, a method for manufacturing an iron core product includes providing an iron core body which includes a magnet insertion hole in which a permanent magnet is disposed, injecting a molten resin into the magnet insertion hole of the iron core body at a first pressure, and setting a pressure applied to the molten resin to a second pressure lower than the first pressure after the molten resin is injected into the magnet insertion hole and before the molten resin is cured.

A glove structure and its manufacturing method are illustrated. An edge of a piece disposed on a glove core of a glove structure is to injected and filled with molding material to have an injection molding assembly thereon. The injection molding assembly at least fills a section gap between the glove core and the edge of the piece. By using the injection molding assembly, the section gap between the glove core and the edge of the piece is masked, and an adhesive effect for bonding the piece is also obtained. Thus, the present disclosure provides positive and reliable means for preventing the edge of the piece from being separated from the glove core, making the glove structure maintain its required function in long term, increasing the quality and the lifetime of the glove structure, and making the glove structure have a curved surface shape to present its three-dimensional shape.
