    • An internally hollow body (1) made of plastic has a cavity (2) for containing liquid, solid or gaseous material, and comprises a main body (4) shaped and having an inner surface (8) that defines at least partially the cavity (2). The inner surface (8) terminates in a shaped edge (10) that delimits a coupling aperture (12) to the cavity (2). The internally hollow body (1) further comprises a closure body (14), having an outer sealing surface (18) suitable to engage at least partially with the inner surface (8) of the main body (4). This closure body (14) is suitable to close at least partially the cavity (2) in correspondence of the coupling aperture (12). The main body (4) is joined to the closure body (14) at least partially along the shaped edge (10) by means of a joining element (20), over-moulded to the main body (4) and the closure body (14) and covering said over-moulding seat resulting between the main body (4) and the closure body (14). A method for making the internally hollow body (1) provides for over-moulding the joining element (20) by injection moulding for example with the use of an over-moulding mould (500).
    • 由塑料制成的内部中空体(1)具有用于容纳液体,固体或气体材料的空腔(2),并且包括主体(4),该主体(4)成形并具有内表面(8),该内表面(8)至少部分地限定空腔 2)。 内表面(8)终止于成形的边缘(10),该边缘限定了与空腔(2)的耦合孔(12)。 内部中空体(1)还包括封闭体(14),该封闭体具有适于至少部分地与主体(4)的内表面(8)接合的外密封表面(18)。 该封闭体(14)适合于对应于耦合孔(12)至少部分地封闭空腔(2)。 主体(4)通过连接元件(20)至少部分地沿着成形边缘(10)连接到封闭体(14),包覆模制到主体(4)和封闭体(10) 并覆盖在主体(4)和封闭体(14)之间形成的包覆成型座。 用于制造内部中空体(1)的方法例如通过使用包覆模制模具(500)通过注射模制来包覆模制连接元件(20)。

    • A mold fabrication element (120) has a hollowed volume (150) defining a respective continuous inner surface. A fabricator resource (140) disposes the mold fabrication element (120) into a cavity (220) of an injection mold assembly; surface contours on the inner surface of cavity as well as the respective continuous inner surface of the mold fabrication element exposed in the cavity define an outer surface of a resulting injection molded part. To create the injection molded part, the fabricator resource injects liquefied material into the cavity (220). The injected material contacts the continuous inner surface of the hollowed volume in the mold fabrication element as well as the surface contours of the cavity. After the injected material solidifies, the fabricator resource removes a combination of the injection molded part and the mold fabrication element. The fabricator resource separates the mold fabrication element from the injection molded part for further processing and use of the injection molded part.
    • 模具制造元件(120)具有限定相应连续内表面的中空体积(150)。 制造商资源(140)将模具制造元件(120)布置在注塑模具组件的空腔(220)中; 腔体内表面上的表面轮廓以及暴露在腔体中的模具制造元件的相应的连续内表面限定了所得到的注塑部件的外表面。 为了形成注塑部件,制造商资源将液化材料注入空腔(220)。 注入的材料接触模具制造元件中的中空体积的连续内表面以及空腔的表面轮廓。 在注入的材料固化之后,制造商资源移除注塑部件和模具制造元件的组合。 制造商资源将模具制造元件与注塑部件分开以进一步处理和使用注塑部件。
