Injection chamber for a metal injection machine

摘要

injection chamber for a metal injection machine. the injection chamber (ci) comprises a tubular body (10) formed by a feed portion (10a) having a radial feed window (13) for receiving a molten metal charge (me) and into which it is incorporated an injection portion (10b) provided with an outlet end (12) open into a molding cavity (4) with a piston (5) being displaced within the tubular body (10), In order to inject the molten metal (mf) into the molding cavity (4), the feed portion (10a) has its inner region, which receives the impact of the molten metal (mf) charge spill covered by an insert (20) formed in a high melting point alloy and having an inner arc contour coinciding with that of the feed portions
