Apparatus for forming a cone for housing a needle in a syringe, method for making a cone for housing a needle in a syringe, and the syringe thereof

A forming apparatus of a housing cone of a needle in a syringe body of a glass syringe for medical substances, the forming apparatus comprising:

• a forming tool configured to form a hole in the syringe body, and
• at least one dispensing device of lubricant-coolant liquid in a contact zone between said forming tool and the syringe body,
• wherein the forming tool comprises
• a grip or shank portion suitable to be gripped and moved by respective motor means,
• a tip suitable for forming said hole on the syringe body,
• a tip body, between the tip and the grip or shank portion, suitable for making said hole, and
• the grip or shank portion, the tip body and the tip being in one piece and aligned along a prevailing extension and rotation axis of the syringe body and/or the forming tool, wherein:
• the tip body, with respect to a cross-sectional plane perpendicular to the prevailing extension axis, has a non-circular cross section, inscribed within a maximum circle having as its radius a maximum distance between a point of said cross section and the prevailing extension axis, measured on said cross-sectional plane perpendicular to the prevailing extension axis, such that the tip body has an overall cross section smaller than the cross section of the maximum circle, and
• the tip and tip body are made of a ceramic material doped with an yttrium compound and are free of tungsten.
