Special purpose machines for optimizing container business

At Aoki, we utilize our extensive experience in the development of injection stretch blow molding machines to provide molding systems that meet the needs of our customers' container businesses. We offer special purpose molding machines tailored to container purpose (contents and usage environment), production volume and other conditions.

We can also address special molding demands such as molding with special materials, clean room molding, and factory inline molding. Whatever issues you face, let us know about them. We will do our utmost to help you build the ideal molding environment.

Greater flexibility

The AL Series enables outstanding high cycle molding with a wide variety of molding materials for all sorts of applications. Even for low specific gravity PP/HDPE or heavy, thick-walled containers, injection capacity does not constrain cavity number.

We are now able to mold high-quality containers by applying ISBM advantages to molding areas such as PE (polyethylene), which previously required extrusion blow molding.

You can also expect to be able to significantly increase production volume by eliminating excessive and unnecessary specifications. AL machines can manufacture all kinds of containers from low to high value-added containers.

High-speed mold release technology

High-speed mold release is a molding method that can dramatically boost production volume by minimizing preform injection and cooling time. We developed it as a new alternative to molding in which cycle time is determined by biaxial orientation molding theory and preform thickness.

By making the most of this molding method, you will dramatically increase production volume of the same container compared with your current method.

Equipped with high plasticization unit

There are many other advantages in addition to high cycle molding to combining high plasticization units with conventional mold clamping mechanisms. One of those advantages is greater plasticizing capacity at low temperatures.

This enables preforms to be molded at lower temperatures, thereby shortening injection/cooling time. As a result, molding cycle time is also not constrained by metering time. Furthermore, improved melting and kneading capabilities result in better molten resin condition at lower speed rotation, helping to enhance the moldability of a wide variety of molding materials.

AOKI Series: Injection stretch blow molding machines that support 100% PET flake molding

AOKI Series machines are injection stretch-blow molding machines that enable containers to be molded directly from flake material made from ground, washed PET bottles.

The mainstream approach to recycling PET used to require pellet material, but with the AOKI Series machines, costs associated with re-pelletizing or re-crystallizing the recyclate are now a thing of the past.

Molding recycled flakes directly into containers

AOKI Series machines use a unique barrel venting system that removes moisture content and impurities from the resin, making stable production of high quality products possible.
