The invention relates to a method for manufacturing a dental scaler tip using a powder injection molding process, a mould, and a scaler tip that is excellent in shape-reliability and injects fluid to a front end thereof along a curved section of the tip. The method comprises the steps of preparing feedstock and injecting the feed stock into a mould to form a molding body, wherein, the mould comprises an operating section to which cylindrical core pins having multi steps and an eccentric end formed at a front end thereof for forming the fluid passage is mounted; and a pair of slide cores disposed for supporting the eccentric ends of the core pins such that the slide cores face each other and are slid in the direction perpendicular to the movement direction of the core pins to form a cavity corresponding to a shape of an article to be formed.

The invention claimed is: 1. A method for manufacturing a dental scaler tip, the dental scaler tip comprising a coupling section having a fluid passage formed therein and a curved tip section that extends from the coupling section, the method comprising:mixing a raw material powder containing titanium (Ti) or stainless steel combined with a binder to prepare feedstock;injecting the prepared feedstock into a mould so as to form at least one mould body at at least one corresponding core pin provided in the mould, the at least one corresponding core pin having multiple steps formed thereon and an eccentric distal end so as to form the fluid passage of the scaler tip;moving an operating plate of the mould in a first direction away from a fixing plate of the mould so as to move first and second slide cores of the mould in a second direction away from each other and remove the at least one core pin from the at least one mould body; andejecting the at least one mould body from the mould.
