Method and blow-molding machine for the blow-molding production of containers that are sterile at least in certain regions

A method for the production of blow-molded containers that are sterile at least in certain regions, and a blow-molding machine configured to carry out the method. In accordance with the method, blowing stations are arranged on a rotating blowing wheel. A preform of a thermoplastic material is first heated and then stretched in a blowing station by a stretching rod and subjected to a pressurized blowing fluid via a blowing nozzle. A sterilizing fluid is supplied to the preform in the blowing station to perform a sterilization. The sterilizing fluid is fed into the preform from an outlet and is carried away again via an inlet and in between follows a flow path. The sterilizing fluid is made to pass through or pass by the stretching rod on its flow path, and the sterilizing fluid is supplied while the blow-molding machine continues to operate.

20230143940 · 2023-05-11 · ·

A system for manufacturing a thermoplastic part from a blank part having a first moulding member and a second moulding member which are configured to cooperate together. A first heating body configured to heat the first moulding member and conductively heat the blank part. Two thermal insulation members are configured to cooperatively define a closed cavity in which at least the moulding members and the first heating body are arranged. A casing defining an internal volume in which at least the moulding members, the first heating body and the thermal insulation members are arranged, and a suction member is configured to lower the internal pressure in the internal volume to compress the preform part between the moulding members.

Container preform

Described herein, amongst other things, is a container preform that is blow moldable into a container. The container preform includes a tubular body having a neck finish and a base at an open end and a closed end thereof respectively. The base is defined between inside and outside curved surfaces at least one of which is composed of multiple tangential curves, wherein an elongate portion is defined between adjacent inside and outside concentric curves that define a thinnest bottom wall thickness of the base having a constant minimum thickness that is smaller than or equal to a wall thickness of the body.

DEVICE FOR MANUFACTURING A STIFFENED PANEL MAKING IT POSSIBLE TO CONTROL THE GEOMETRY OF SAID STIFFENED PANEL, AND METHOD FOR MANUFACTURING A STIFFENED PANEL USING SAID DEVICE
20230182426 · 2023-06-15 ·

A device for manufacturing a stiffened panel with reinforcements which each have a final thickness and a final height. The manufacturing device includes tools configured to each support a preform of fibers having a U-shaped or C-shaped cross section with a base and two wings. Each tool comprises, at at least one of its first and second lateral faces, a set-back portion which, when two tools are juxtaposed, delimits a recess configured to form a reinforcement during a consolidation or polymerization step. The tools are dimensioned such that each recess has a width, at the consolidation or polymerization temperature, that is substantially equal to the thickness of the reinforcements. This solution makes it possible to more effectively control the geometry of the stiffened panel by avoiding the formation of beads. A method for manufacturing a stiffened panel using the device is also disclosed.

Process of manufacturing an injection mould component

An injection mold component for molding the outer surface of a preform neck, which allows improved cooling of the preform neck inside the mold, while at the same time reducing the mold cycle time. A related production process of said injection mold component, which allows the section of the cooling channels to be optimized, determining a more effective cooling, is also described.

Mold for a tire with an annular insert made up of a plurality of portions

A mold for vulcanizing and molding a tire is provided herein. The tire includes a tread delimited by two sidewalls, the mold including a ring for molding the tread of the tire and two shells for molding the sidewalls. The mold includes an annular groove extending in a recessed manner in one of the shells and an insert housed in the groove, this insert having tire marking elements and being formed from a plurality of insert parts that are positioned one after another in the annular groove.

Container, preform assembly and method and apparatus for forming containers

Container comprising an inner container and an outer container with facing surfaces, wherein at least part of at least one of the facing surfaces has a surface roughness higher than about 0.1 Ra and/or wherein the difference in roughness of the facing surfaces is at least over a part more than about 0.1 Ra.

Method and System for Producing a Threaded Bolt
20170312948 · 2017-11-02 ·

The invention relates to a method for producing a threaded bolt. A blank is introduced into a threaded-bolt negative mold. The blank has a bolt-shaped portion. Fibers which are aligned in the longitudinal direction of the bolt-shaped portion are embedded in a plastics material in the blank. Pressure is exerted on the blank in order to deform the blank in the negative mold such that a threaded structure is formed on a circumferential face of the bolt-shaped portion. The invention moreover relates to a threaded bolt which is manufacturable by this method, and to a system which is conceived for carrying out the method. Lightweight and hard-wearing threaded bolts may be manufactured by the method according to the invention.
