One-piece component and method for its production |
摘要 |
A one-piece component includes a first subregion made of a base material, and a second subregion made of the base material as binder with intercalated hard material particles, the second subregion being injection-molded onto the first subregion by means of MIM injection molding, so that an integral connection is formed between the first subregion and the second subregion. Furthermore, a method for producing the one-piece component by means of MIM injection molding is described. |

1. A one-piece component forming a cylinder without a hole, comprising:
a first subregion made of a base material, the first subregion being a cylindrical core portion of the cylinder, the cylindrical core portion being without a hole, the cylindrical core portion having an outer radius, and a second subregion made of the base material as binder with intercalated hard material particles, the second subregion being an outer ring portion of the cylinder, the outer ring portion having an inner radius and an outer radius, the inner radius of the outer ring portion being equal to the outer radius of the cylindrical core portion, the outer radius of the outer ring portion being greater than the outer radius of the cylindrical core portion, wherein the cylindrical core portion and the outer ring portion are concentric, the second subregion being injection-molded onto the first subregion by means of MIM injection molding, so that an integral connection is formed between the first subregion and the second subregion. |
