摘要:
A method and apparatus for blow molding a case (10) for housing an object, such as a tool, is disclosed generally comprising first and second mold (52,54) portions located adjacent each other to create separate cavities for forming base (24) and lid (34) portions of a case (10) and a punch for each portion corresponding to the outline of an object. In certain embodiments, the punch protrudes into the cavity during blow molding to create a sidewall to facilitate a press fit. In some embodiments, additional punches and/or recesses are provided to produce additional apertures or flanges in the walls of the tool case.
摘要:
(Object) To provide a method of manufacturing a resin hollow molded body wherein, predetermined parts can be simply attached when attaching them in the inside of the blow molded hollow body; and the resin hollow molded body, such as a vehicle fuel tank containing a volatile liquid inside thereof, has a good barrier property against a gas component. (Means for solving the problem) There is provided a method for obtaining a product of a hollow molded body characterized in that : a thermoplastic resin parison 6, extruded to a tubular state, is expanded by blow molding; then dies 2, 4 are once divided to assemble predetermined parts 32, 34 inside of the hollow molded body; and the surfaces of the divided dies are joined again.
摘要:
The invention relates to a method for producing a container from thermoplastic material having a connection element (5) passing through the wall thereof. The method comprises making available at least one plate-shaped or shell-shaped or tube-shaped preform (3) made of plasticized thermoplastic material, introducing the preform (3) into a multipart molding tool (1) having cavities defining at least one molding recess, molding and final shaping of the preform (3) within the molding tool (1) using differential pressure, piercing of the still warm-plastic preform (3) from the tool side by means of a mandrel (9) in order to produce an opening (6) in the preform (3), insertion from the molding recess side of a connection element (5) into the opening (6) produced by the mandrel (9), and connection of the connection element (5) to the preform (3).
