The invention relates to a method for manufacturing an ultrasonic tip for an apicoectomy, such that the tip has a shape suitable for the shape of a tooth root, comprising the steps of: forming a feedstock by mixing a metal powder including stainless steel with a binder; injecting the feedstock to form an injection-molded part having a plurality of projections integrally formed on the surface thereof; performing debinding to remove the binder from the injection-molded part; sintering the injection-molded part; and performing annealing to increase the ductility and facilitate the bending of the sintered part.

The invention relates to a scaler tip for a dental implant, manufactured by injection molding silver, copper, silver alloy, or copper alloy powder, as well as to a method for manufacturing same. The scaler tip for a dental implant comprises: a shank portion; and a work portion which extends in one direction from the shank portion which is curved. The above-described scaler tip for a dental implant is manufactured by injection molding the powder of one or more of silver, copper, a silver alloy, and a copper alloy.

Disclosed is a method of manufacturing a refrigerant distributor for air conditioning and a refrigerant distributor manufactured thereby. The manufacturing method includes mixing copper powder with 30-60 vol% of a binder based on the volume of the copper powder, thus preparing a mixture for injection molding, subjecting the mixture to injection molding using a mold, thus producing an injection molded body having the shape of a distributor, removing the binder from the injection molded body, and sintering the binder- free molded body in a sintering furnace at 800-115O0C in a reducible or inert atmosphere, the method being thereby favorable for mass production owing to omission of additional mechanical processing and enabling the manufacture of a distributor having a smaller size, as for adaptation for the miniaturization of an apparatus, reducing loss of material, and leading to low manufacturing costs.
