Method for producing foam blow-molded article
10974435 · 2021-04-13 · ·

A method for producing a foamed blow-molded article, which includes extruding a physical blowing agent-containing foamable molten resin downwardly through a annular die to form a tubular foamed parison, clamping the foamed parison between split molds, and then blow molding it. At the latest before completion of the clamping of the foamed parison between the split molds, a gas is blown toward an inner peripheral surface of an upper portion of the foamed parison, the bottom portion of which has been closed, from a gas ejection outlet located within the foamed parison at a position immediately below the annular die to widen the foamed parison.

Supporting assembly for hollow tank body and forming method for hollow tank body

A supporting assembly for a hollow tank body includes a supporting body (2) and supporting ends (1) provided at two ends of the supporting body. The supporting ends are provided with stepped transition assemblies (4) connected to the supporting body. The supporting body is configured with a hollow structure. The supporting body includes a supporting main body (5) and a base (6). The supporting main body is configured with a cylindrical structure or a cylindrical structure with a corrugated structure in the middle. With this structure, the deformation of the hollow tank body under the relatively high overpressure and the low negative pressure can be avoided, and the shape stability of the whole product can be enhanced. Meanwhile, the supporting structure needs less material, and has a light weight and lowered cost.

Volume controlled blowing-air feed

A device for controlling a blow-molding machine for producing a thermoplastic container, wherein a blowing gas for blow-molding the container is introduced into a thermally conditioned preform, while the preform is held in a blow mold of the blow-molding machine. The blowing gas is introduced during a preblowing phase into the preform so that the temperature-conditioned material of the preform approaches the walls of the blow mold. The blowing gas is introduced during a following finish-blowing phase into the preform so that the temperature-conditioned material of the preform is pressed into the contours of the blow mold walls. The volumetric flow rate of the blowing gas is determined at least during the preblowing phase by an adjustable flow-control valve that can be controlled by a control unit that generates a control signal for adjusting the flow-control valve. The flow-control valve is adjusted as a function of the control signal.

METHOD OF DELIVERING A LIQUID VOLUME AND ASSOCIATED APPARATUS

An apparatus for forming a container from a preform and delivering a predetermined volume of a liquid end product, formed by the addition of first and second liquid products, into the container. The apparatus includes a heating oven to heat the preform, a mold defining a cavity in the shape of the container, a stretch member coupled to an actuator to stretch the preform in the mold, an injection head configured to inject the second liquid product through the mouth of the preform so as to cause expansion of the preform within the mold thereby obtaining the container, and a preform filler to at least partially fill the preform with the first liquid prior to injecting of the second liquid product and before expanding of the preform into the container.
