Wikimedia Commons has media related to Blow molding. Types of EBM equipment may be categorized as extrsion. Our Engineering Department has a very strong experience in the 2D and 3D extrusion blow moulding and associated auxiliary equipment. Very high volumes are produced.

It defines also the machining data of the different parts to be manufactured according to the machinery available and it programs the different parts. Our Engineering Department has a great expertise in the different methodologies dedicated to the mould. Each material has its own shrinkage value. EBM processes may be either continuous constant extrusion of the parison or intermittent. 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 shapes, multiple layers.

To design a prototype or production blow mould, we work with 2 CAD softwares 3D: Retrieved 22 September 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.

The cost of blow molded parts is higher than that of injection-molded parts but lower than rotational molded parts. This was the beginning of the commercial blow molding process. A design office accompany throughout the whole of your ptoject: Design soufflave implementation of moulds. We draw the split line, which is a stretched soufflag from 30 to 40mm on both sides of the part and, which is perpendicular to the direction of mold opening.

In the ISB process, the preforms are heated typically using infrared heaters above their glass transition temperature, then blown using high-pressure air into bottles using metal blow molds. This is trimmed off by spinning a knife around the container which cuts the material away. In the two-stage injection stretch blow molding process, the plastic is first molded into a “preform” using the injection molding process.


Floor space required is high, although compact systems have become available. Design and implementation of parts in 2D and 3D blow moulding.

Indeed, ActuaPlast has an in-house design office consisting of more than 10 persons: In this case the screw may turn continuously or intermittently. Handles can’t be incorporated. In extrusion blow molding EBMplastic is melted and extruded into a hollow tube a parison. The technical mechanisms needed to sokfflage hollow bodied workpieces using the blowing technique were established very early on.

As the preform is not released during the entire process the extrusiln wall thickness can be shaped to allow even extrusioon thickness when blowing rectangular and non-round shapes. Once the plastic has cooled and hardened the mold opens up and the part is ejected.

The end of the core rod opens and allows compressed air into the preform, which inflates it to the finished article shape. Titanium coated blades are often used rather than standard steel to increase life by a factor of 30 times.

All equiped with robots that are able of injecting pieces of 5 Kg. The process is divided into three steps: By using this site, you agree to the Terms of Use and Privacy Policy.

The cavity mold forms the external shape and is clamped around a core rod which forms the internal shape of the preform. 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.

It is a very important step in the design of extrusiom mould.

Air is then blown into the parison, inflating it into the shape of the hollow bottlecontainer, or part. There are three sets of core rods, which allow concurrent preform injection, blow molding and ejection. After the plastic has cooled sufficiently, the mold is opened and the part is ejected. souufflage


This is the least-used of the three blow molding processes, and is typically used to make small medical and single serve bottles. Highly suitable for low volumes and short runs.

A technical offer responding to all of your requirements A design office accompany throughout the whole of your ptoject: This page was last edited on 11 Novemberat To make wide neck jars spin trimming is necessary.

The preform and blow mold can have many cavities, typically three to sixteen depending on the article size and the required output.

This has two main different methods, namely Single-stage and two-stage process. The accumulator head or reciprocating screw methods use hydraulic systems extrsuion 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.

We suggest some arrangements on the parts in order to optimize the process addition of reference points and welding areas for example. Only a champagne base can be made for carbonated bottles.

For specific shapes that do not release naturally, we set up some movements to make the ejection of the part easier. Restrictions on bottle design. Advantages of extrusiion molding include: In continuous extrusion blow molding the parison is extruded continuously and the individual parts are cut off by a suitable knife.

These soufflafe are packaged, and fed later after cooling into a reheat stretch blow molding machine. 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. Manufacture of your assemblies and sub-assemblies.
