Powder injection molding binder, powder injection molding composition and method for production of sintered member |
摘要 |
An injection molding binder permitting formation of a molded article incapable of sustaining such defects as a crack or an expansion at the degreasing step and allowing the degreasing treatment to be completed quickly, an injection molding composition, and a method for the production of a sintered member are disclosed. The powder injection molding binder contains a polymer (I) which is obtained by polymerizing a monomer component composed of 50 to 100% by weight of a long side chain-containing monomer and 0 to 50% by weight of other polymerizable monomer. The powder injection molding composition comprises the binder, a binder auxiliary, and a powdery material capable of sintering. The method for the production of a sintered member comprises the steps of injection molding the composition, subjecting the molded mass to a degreasing treatment, and sintering the degreased molded mass.
