摘要: In disposing an insert or inserts within a blow-molded product, before the blow molding step is started, an inner supporting device supporting the insert at an end thereof is inserted into a parison and then the mold is closed so that the insert is made into contact with the parison. Thereafter the blow molding is effected so that the insert is securely welded to the parison.

摘要: An extrusion head for use in blow molding machines for molding parison having a single layer or wall or a plurality of layers or walls, in which a plunger is slidably interposed between a head body and a core and the plastic material is successively accumulated in an accumulation chamber defined between the extruding end of the plunger, the head body and the core so that the faster the plastic material is introduced into the extrusion head, the faster it is extruded.

摘要: A blow molding method and machine and more particularly a method and machine for extruding a multi-layer parison for blow molding, wherein at least two layers of molding plastics, each plastic compensating the poor or undesirable physical and chemical properties of the other plastic and/or each having a different color are forced to flow through different passages having an annular cross sectional configuration, and are joined at the junction of a short passage to be extruded into a multi-layer parison.
