A method for machining by laser ablation or by micro-milling a raised and/or hollow structure on an impression of an injection mould. A method for manufacturing a ceramic or cermet item by injection using the injection mould to produce an item, and in particular a watch bezel, decorated directly during the injection.

A method for manufacturing an aeronautical part utilizes injection molding. After injecting the prepared mixtures to obtain two green blanks, an assembly area of at least one of these two blanks is heated. The blanks are assembled and then debinding is carried out. A sintering treatment is then carried out.

A thixomolding material includes: a metal body that contains Mg as a main component; and a coating portion that is adhered to a surface of the metal body via a binder and contains SiO.sub.2 particles containing SiO.sub.2 as a main component. An average particle diameter of the SiO.sub.2 particles is less than 20.0 μm, and a mass fraction of the SiO.sub.2 particles in a total mass of the metal body and the SiO.sub.2 particles is 1.0 mass % or more and 40.0 mass % or less. The binder may contain waxes. A content of the binder may be 0.001 mass % or more and 0.200 mass % or less.

A thixomolding material includes: a metal body that contains Mg as a main component; and a coating portion that is adhered to a surface of the metal body via a binder and contains C particles containing C as a main component. A mass fraction of the C particles in a total mass of the metal body and the C particles is 5.0 mass % or more and 40.0 mass % or less. The binder may contain waxes. The C particles may be graphite particles.

A method for producing a composite magnetic body includes: pressure molding a metal magnetic material into a predetermined shape, the metal magnetic material being an Fe—Si-based metal magnetic material; performing a primary heat treatment of heating the metal magnetic material in an atmosphere with a first oxygen partial pressure to form an Si oxide coating film on a surface of the metal magnetic material; and performing a secondary heat treatment of heating the metal magnetic material that has undergone the primary heat treatment in an atmosphere with a second oxygen partial pressure, which is higher than the first oxygen partial pressure, to form an Fe oxide layer at least partially on a surface of the Si oxide coating film.

A method for fabricating a vane for a variable geometry turbocharger (VGT) includes the steps of providing or obtaining a substrate metal in powdered form, mixing a binder with the powdered substrate metal to form a mixture, performing an injection molding process using the mixture to form a green substrate in the shape of the vane, debinding the green substrate to form a brown substrate in the shape of the vane having a porous structure, applying a surface treatment slurry to at least a portion of the brown substrate, and sintering the surface treated brown substrate to form the vane.
