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

A technical offer responding to all of your requirements A design office accompany throughout the whole of your ptoject: The machining and the assembly of the different parts of the mould are implemented in our workshops. A design office accompany throughout the whole of your ptoject: Let us put our know-how and our expertise eextrusion your service to guide you during the edtrusion or designing phases of your parts from prototyping to full production of the final plastic part.

In other projects Wikimedia Commons. Restrictions on bottle design. These “crosses” fit together leaving little space as more surface area is contacted thus making the material less porous and increasing barrier strength against permeation.

Blow molding

In the two-stage injection stretch blow molding process, the plastic is first molded into a “preform” using the injection molding process. In general, there are three main types of blow molding: The preform mold opens and the core rod is rotated and clamped into the hollow, chilled blow mold. In the United States soft drink industrythe number of plastic containers went from zero in to ten billion pieces in Thanks to a strong experience in the mould industry, ActuaPlast designs and manufactures moulds aimed at the 2D and 3D blow moulding for different industries: In the IBM process, the polymer is injection molded onto a core pin; then the core pin is rotated to a blow molding station to be inflated and cooled.

This parison is then captured by closing it into a cooled metal mold.

Soufflagge the plastic has cooled sufficiently, the mold is opened and the part is ejected. The first mass production of plastic bottles was done in America in Blow molding BrE moulding is a specific manufacturing process by which hollow plastic parts are formed and can be joined together: In the ISB process, the preforms are heated typically using infrared heaters above soufflagr glass transition temperature, then blown using high-pressure air into bottles using metal blow molds.

A project following-up is made at every step of the mould manufacturing. Because glass is very breakable, after the sojfflage of plastic, plastic was being used to replace glass in some cases. By using this site, you agree to the Terms of Use and Privacy Policy. The preform is always stretched with a core rod as part of the process.

The finished article is stripped off the core rod and as an option can be leak-tested prior to packing. 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. Types of EBM equipment may be categorized as follows:.

The process of injection blow molding IBM is used for the production of hollow glass and plastic objects in large quantities.

The parison is then clamped into a mold and air is blown into it.

Our Engineering Department has a great expertise in the different methodologies dedicated to the mould. Retrieved 12 November Floor space required is high, although compact systems have become available. Catia V5 and Solidworks.

Disadvantages of blow molding include: Design and implementation of parts in 2D and 3D blow moulding. Germany started using this technology a little bit later, but is currently one of the leading manufacturers of blow molding machines. Retrieved 22 September No increase in barrier strength as the material is not extrudion stretched. This is high productivity combined with a high technological value. As the preform is not released during the entire process the preform extrusin thickness can be shaped to allow even wall thickness when blowing rectangular and non-round shapes.

These preforms are produced with the necks of the bottles, including threads the “finish” on one end. Preforms can be sold as a completed item for a third party to blow. Handles can’t be incorporated.
