The present invention relates to a barrel for high pressure used in such an injection device or an extruding device. Provided in the present invention is the barrel for high pressure, comprising the wall; and a hollow part formed in the wall and having a screw loaded and moved, wherein a metal heat nailing part in the front end of the wall. According to the present invention, the high intensity is given by the metal heat nailing part to effectively prevent the deformation of the front-end part and the damage of the inner coating layer due to the concentration of the high pressure during the high-speed high-pressure injection (or extrusion) molding. |
