? manufacturing process of connector or metal nozzle for glass syringe containing internal thread? It begins with the cutting of a cylindrical billet in two segments, fitting the parts according to the original design into a one-piece body, creating the male (2) and female (3) pieces, which are perfectly and properly adjusted together. , whose parts are machined individually until they reach the shape illustrated in the design, as shown in figures 3 and 4； on the inner rear face of the female part (3) interference is created (4 and 4a), whose inlet interference (4a) is formed by a larger diameter recess (5) to half (6) of the depth of said inner rear face； tangentially to the larger undercut (5), the smaller undercut (7) protrudes frontally, which comprises, in a face-to-face manner, said interference (4) the front wall (8) of said female part (3) is slightly increased for structural reinforcement effect when introducing the male part (2) into said female (3), due to the snap fit kinetics, avoiding cracks due to the mechanical junction beating between the aforementioned parts； the rear portion of the male part (2) has an integral conformation (9) to the inner rear face (4 and 4a) of the female (3), and its anterior portion is a tapered pin (10) and a central hollow hole (11).?processo de fabricação de conector ou bico metálico para seringa de vidro contendo rosca interna? tem seu inicio com o corte de um tarugo cilíndrico em dois segmentos, adequando as partes de acordo com o projeto original em um corpo monobloco, criando a peça macho(2) e fêmea(3), que se unem de forma perfeita e devidamente ajustadas, cujas partes são usinadas individualmente até chegarem na conformação ilustrada no projeto, conforme mostrado nas figuras 3 e 4 ； na face posterior interna da peça fêmea(3) são criadas interferências(4 e 4a), cuja interferência de entrada(4a) é formada por rebaixo de diâmetro maior(5) até a metade(6) da profundidade da dita face posterior interna ； tangencialmente a
