In continuous extrusion blow molding the parison is extruded continuously and the individual parts are cut off by a suitable knife.
Highly suitable for low volumes and short runs. The cost of blow molded parts is higher than that of injection-molded parts but lower than rotational molded parts.
Extrusion Soufflage
After the plastic has cooled sufficiently, the mold is opened and the part is ejected. Once the plastic has cooled and hardened the mold opens up and the part is ejected. The preform is always stretched with a core rod as part of the process. Assembly Encapsulation Carving Screwing. These preforms are produced with the necks of the bottles, including threads the “finish” on one end. Co-developpement of your parts 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 plastic part.
Disadvantages of blow molding include: Only a champagne base can be made for carbonated bottles. The technical mechanisms needed to produce hollow bodied workpieces using the blowing technique were established very early on. In this case the screw may turn continuously or intermittently.
Blow Moulding
Enoch Ferngren and William Kopitke [1] soifflage produced a blow molding machine and sold it to Hartford Empire Company in Very high volumes are produced. In extrusion blow molding EBMplastic is melted and extruded into a hollow tube a parison. It is a very important step in the design of the mould. The parison is then clamped into a mold and air is blown into it.
It is also used for forming glass bottles or other hollow shapes. Indeed, ActuaPlast has an in-house design office consisting of more than 10 persons: Each material has its own shrinkage value. A project following-up is made at every step of the mould manufacturing. The process is divided into three steps: A design office accompany throughout the whole of your ptoject: In the single-stage process both preform manufacture and bottle blowing are performed in the same machine.

We suggest some arrangements on the parts in order to optimize the process addition of reference points and welding areas for example. The end of the core rod opens and allows compressed air extrusioj the preform, which inflates it to the finished article shape.
As the preform is not released during the entire process the preform wall thickness can be shaped to allow even wall thickness when blowing rectangular and non-round shapes. Retrieved 12 November Small Scale Recycling of Plastics.
