We draw the split line, which is a stretched surface from 30 to 40mm on both sides of the part and, which is perpendicular to the direction of mold opening.
The blow molding process soufflgae with melting down the plastic and forming it into a parison or, in extrusio case of injection and injection stretch blow molding ISBa preform.
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.
A technical offer responding to all of your requirements A design office accompany throughout the whole of your ptoject: Examples of parts made by extruaion EBM process include most polyethylene hollow products, milk bottles, etrusion bottles, automotive ducting, watering cans and hollow industrial parts such as drums. Our Engineering Department has a great expertise in the different methodologies dedicated to the mould.
Single-stage process is again broken down into 3-station and 4-station machines. There are three sets of core rods, which allow concurrent preform injection, blow molding and ejection.

Wikimedia Commons has media related to Blow molding. We suggest some arrangements on the parts in order to optimize the process addition of reference points and welding areas for example. It is also used for forming glass bottles or other hollow shapes. Assembly Encapsulation Carving Screwing. Only a champagne base can be made for carbonated bottles. Small Scale Recycling of Plastics. In other projects Wikimedia Commons. EBM processes may be either continuous constant extrusion of xetrusion parison or intermittent.
No increase in barrier strength as the material souufflage not biaxially stretched.
The air pressure then pushes the plastic out to match the mold. The parison is then clamped into a mold and air is blown into it. Restrictions on bottle design. 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.
In continuous extrusion blow molding extrusoon parison is extruded continuously and the individual parts are exgrusion off by a suitable knife. It is a very important step in the design of the mould.
The technical mechanisms needed to produce hollow bodied workpieces using the blowing technique were established very early on. For example, moldings produced from amorphous materials are much more difficult to trim than crystalline materials. Highly suitable for low volumes and short runs.
Upon completion, we define how the part will be placed into the mould. The process principle comes from the idea of glassblowing. 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.
Once the plastic has cooled and hardened the mold opens up and the part soufdlage ejected. The preform and blow mold can have many cavities, typically three to sixteen depending on the article size and the required output.
The machining and the assembly of the different parts of the mould soufglage implemented spufflage our workshops. 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.
Disadvantages of blow molding include: After a cooling period the blow mold opens and the core rod is rotated to the ejection position. The mold is made in aluminium or in soufflae depending on the quantity to produce prototypes or productions.
A park of seven blowers capable of producing pieces weighing up to 15Kg allowing us to give the best response to demands of the actual market. 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: 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.
Enoch Ferngren and William Kopitke   produced a blow molding machine and sold it to Hartford Empire Company in Barnes; Quoc Pham; Theodore A. According to the material required by the customer a shrinkage is applied on the part.
In this case the screw may turn continuously or intermittently. The preform mold opens and the core rod is rotated and clamped into the hollow, chilled blow mold.
Manufacture of your assemblies and sub-assemblies.
Blow molding BrE moulding is a specific manufacturing process by which hollow plastic parts are formed and can be joined together: These preforms are produced with the necks of the bottles, including threads the “finish” on one end.
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. Manufacture of the corresponding toolings.
A design office accompany throughout the whole of your ptoject: This robot can take a extruison up to 90 Kg, change its tools automatically, do the milling, the carving, and the flame treatment.
