摘要
The invention relates to a method and an arrangement for manufacturing a component with hot isostatic pressing occurring in solid form, the component to be manufactured comprising a shape opening onto the outer surface of the component. The method comprises forming a sheet metal capsule for metallic powder, and manufacturing a core by arranging around a core centre made of a first material a form layer made of a second material, the shape of the outer surface of the form layer corresponding to the shape of the outer surface of the opening shape of the component. The core is placed in a spot, where the shape opening onto the outer surface is to be formed, and metallic powder is arranged in the sheet metal capsule, which forms the body part of the component to be manufactured. Cladding material is arranged between the outer surface of the core and the metallic powder, and hot isostatic pressing is performed to simultaneously compact the metal powder and the cladding material. The invention also relates to a core and a cladding preform, which are suitable for use in the method and arrangement.
