This process also increases the strength to be ideal for filling with carbonated drinks.

Blow Moulding

From Wikipedia, the free encyclopedia. In extrusion blow molding EBMplastic is melted and extruded into a hollow tube a parison.

The mold is made in aluminium or in steel depending on the quantity to produce prototypes or productions. During the s the variety and number of products was still very limited and therefore blow molding did not take off until later.

Once the variety and production rates went up the number of products created soon followed. These preforms are produced extrueion the necks of the bottles, including threads etxrusion “finish” on one end. It is a very important step in the design of the mould.

The accumulator head or reciprocating screw methods use hydraulic systems to push the parison out quickly reducing the effect of the weight and allowing precise control over the wall thickness by adjusting the die gap with a parison programming device.

The air pressure then pushes the plastic out to match the mold. Manufacture of the corresponding toolings. It defines also the machining data of the different parts to be manufactured according to the machinery available and it programs the different parts. Manufacture of your assemblies and sub-assemblies.

Our CAM team is also in charge of the design and of the programmation of the electrodes. Click here to have a look at our detailed machinery list.

To design a prototype or production blow mould, we work with 2 CAD softwares 3D: A brand new park: Retrieved 22 September In the two-stage injection stretch blow molding sofflage, the plastic is first molded into a “preform” using the injection molding process.

At the end of the study, the CAM department, consisting of 4 persons, is responsible for the programming of the different parts of the mould softwares used: A design office accompany throughout the whole of your ptoject: Single-stage process is again broken down into 3-station and 4-station machines. The molten polymer is fed into a hot runner manifold where it is injected through nozzles into a heated cavity and core pin.

The technical mechanisms needed to produce hollow bodied workpieces using the blowing technique souffllage established very early on. Today, even a greater number of products are blown and it is expected to keep increasing.

A technical offer responding to all of your requirements A design office accompany throughout the whole of your ptoject: After the extusion has cooled sufficiently, the mold is opened and the part is ejected.

Advantages of blow molding include: Views Read Edit View history.

To make wide neck jars spin trimming is necessary. There are three sets of core rods, which allow concurrent preform injection, blow molding and ejection. The process principle comes from the idea of glassblowing. No increase in barrier strength as the material is not biaxially stretched. extgusion

Disadvantages of blow molding include: Our quality service garantees you an optimal result, completed with our high capacity machines and modern means of manufacture. A renewed park of 5 machines: Little restriction on bottle design.

Handles can’t be incorporated.

Blow molding BrE moulding is a specific manufacturing process by which hollow plastic parts are formed and can be joined together: This has two main different methods, namely Single-stage and two-stage process.

Small Scale Recycling of Plastics. 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 exttrusion cooled.
