The process is divided into three steps: Design and implementation of parts in 2D and 3D blow moulding. These preforms are produced with the necks of the bottles, including threads the “finish” on one end.

Manufacture of the corresponding toolings. The end of the core rod opens and allows compressed air into the preform, which inflates it to the finished article shape.

After the plastic has cooled sufficiently, the mold is opened and the part is ejected. Extrusio of your assemblies and sub-assemblies. The parison is a tube-like piece of plastic with a hole in one end through which compressed air exrusion pass. Air is then blown into the parison, inflating it into the shape of the hollow bottlecontainer, or part.

The finished article is stripped off the core rod and as an option can be leak-tested prior to packing.

Floor space required is high, although compact systems have become available. Once the design of the mold finished, we make a design review of the mould to validate the study, the technical file is transmitted to the CAM department to program the tool paths WORK NC.

The first mass production of plastic bottles soufrlage done in America in The preform is always stretched with a core rod as part of the process. Construction of a m2 factory on a 10 m2 ground Lauching of our rotation moulding unit to diversify and complete our offer on big pieces with inserts, complex soufdlage, multiple layers.

After a cooling period the blow mold opens and the core rod is rotated to the ejection position. This is trimmed off by spinning a knife around the container which cuts the material away. In general, there are three main types of blow molding: Small Scale Recycling of Plastics.

Blow molding

Our quality service garantees you an optimal result, completed with our high capacity machines and modern means of manufacture. Our CAM team is also in charge of the design and of the programmation of the electrodes.

In the single-stage process both preform manufacture and bottle blowing are performed in the same machine.

In the two-stage injection stretch blow molding process, the plastic is first molded into a “preform” using the injection molding process. According to the material required by the customer a shrinkage is applied on the part.

The blow molding process begins with melting down the plastic and forming it into a parison or, in soufflqge case of injection and injection stretch blow molding ISBa preform.

Retrieved 22 September Lauching of our rotation moulding unit to diversify and complete our offer on big pieces with inserts, complex shapes, multiple layers. With the accumulator method, an accumulator gathers melted plastic and when the previous mold has cooled and enough plastic has accumulated, a rod pushes the melted plastic and forms the parison.

Highly suitable for low volumes and short runs. A project following-up is made at every step of the mould manufacturing. Let us put our know-how and our expertise at your service to guide you during the engineering or designing phases of your parts from prototyping to full production of the final extusion part.
