Abstract

Abstract A method and means of embedding thin wall tubular material in plastic under high pressure conditions in disclosed herein. The means of this invention comprises a first plate means with a plurality of spaced apart studs extending upwardly therefrom which are adapted to support tubular members thereon in substantially vertically disposed position. A casting means is positioned above the first plate means and has a cavity formed therein which is adapted to receive casting material therein and which is adapted to receive the tubular members therein when the casting means is moved downwardly with respect to the first plate means. The casting means has a plurality of guide openings formed therein at the upper end of the cavity which are adapted to receive the tempered upper ends of the tubular members to properly position the same when the casting means is moved to its lower position. Heating elements are also provided to heat the casting material to cause the same to harden at the proper time. The method of embedding the tubular members in the casting material is disclosed with the method causing the tubular members to be properly positioned in a parallel, spaced apart manner so that the finished product can be used as a fluid manifold in an injection machine.
