Abstract
A method of manufacturing a syringe for use in enteral feeding includes providing a premolded syringe body having a plunger end and an outlet end, loading the premolded syringe body into a mold having a core pin extending into the outlet end of the premolded syringe body, closing the mold to thereby retain the premolded syringe therein and to close a mold cavity around the outlet end of the syringe body, injection molding by injecting plastic molding material into the mold cavity and cooling to thereby form a tip at the outlet end of the premolded syringe body, and opening the mold and extracting the syringe body and the tip.
Claims5
A method of manufacturing a syringe for use in enteral feeding, the method comprising:
- providing a premolded syringe body having a plunger end and a forwardly projecting outlet end;
- loading the premolded syringe body into a mold having a core pin extending from an internal cavity block and into the outlet end of the premolded syringe body, the cavity block having a cavity in the shape of a tip located adjacent the outlet end of the premolded syringe body for forming an enteral tip free of a mold parting line therein;
- closing the mold to retain the premolded syringe body and internal cavity block therein;
- injection molding by injecting plastic molding material into the mold cavity, and cooling the plastic molding material for simultaneously forming a tip free of a mold parting line in the tip cavity located around the core pin and the outlet end, simultaneously bonding the tip to the outlet end of the premolded syringe body;
- and
- opening the mold and extracting the premolded syringe body with the tip bonded thereto.

- closing the mold to retain the premolded syringe body and internal cavity block therein;
- injection molding by injecting plastic molding material into the mold cavity for filling the tip cavity and groove, and cooling the plastic molding material for simultaneously forming a tip free of a mold parting line in the tip cavity located around the core pin and a cover in the groove surrounding the outlet end, simultaneously bonding the tip to the outlet end of the premolded syringe body;
- and
- opening the mold and extracting the premolded syringe body with the tip bonded thereto.
