摘要： PROBLEM TO BE SOLVED: To provide a ceramic pipe integrated type ferrule that excels in dimensional accuracy and surface quality and to provide a method of manufacturing it in a single process at low cost. SOLUTION: In a state where a ceramics pipe 10 is inserted and held in a metallic die 1 that has a cavity for prescribing the contour of an optical connector ferrule, a high temperature fluid material, e.g. a molten alloy material A is poured, cooled and solidified. Thus the ceramics pipe integrated type ferrule is manufactured that encloses the ceramics pipe integrally strongly fixed inside the ferrule. An alternative method is such that, with a ceramics pipe inserted in a discharging hole at the lower end of a container which stores a high temperature fluid material, while the pipe is moved downward, the material is discharged so as to cover the outer circumferential face of the pipe, then cooled and solidified to form the ferrule; or, that, with the ceramics pipe inserted along the center axis of a round bar which is made of an amorphous alloy in a subcooled fluid state, the amorphous alloy is cooled and solidified to form the ferrule.

摘要： PROBLEM TO BE SOLVED: To provide a method and an apparatus for manufacturing a casting product having a small hole at a low cost, with a high productivity and in a short time by reducing troubles that may be caused in the difficulty of a draw of a linear core material after casting or caused in its durability. SOLUTION: A casting product 4 having a small hole 5 with a wire cross section shape is manufactured by using a surface coated or surface treated wire as the due wire when molten metal is casted into a cavity 2 of a mold 1 to which a wire 3 (linear core material) with a desired cross section shape is preset, and by enabling only the wire to be drawn as its membrane formed by surface coating or surface treatment is partially or totally exfoliated by the draw. When the wire is drawn out of a casting material after casting, the wire can be drawn as well, by employing a material of high elastic limit to the wire, out of the inside of the casting material as a diameter of the wire becomes small by its elastic deformation in the direction of the draw.
