OLEODYNAMIC INJECTION MOULDING
The new oleodynamic injection molding system
As a natural evolution of the Pneumatic Injection Molding technology and in response to the growing demand to inject materials in larger quantities and sizes, we have developed the new Oleodynamic Injection Molding system.
This solution allows you to print objects with a volume of up to 100 cm³. The new plastic molding system uses an oleodynamic pump to generate the necessary injection pressure, ensuring greater precision and process control.
The new project by Robot Factory Srl adopts a portal structure to ensure greater robustness, thus responding to new technical needs. This system is able to reach an extrusion force of up to approximately 2 t (1,900 kg) and can be supplied in different configurations depending on production needs. Furthermore, upon request, it can be supplied with a vise that reaches up to approximately 4 t (4,300 kg) in closing.
This system works by heating the plastic in a heating chamber, once the plastic is at its melting point, it is injected into a mold, so the plastic takes the shape of the mold. When the plastic cools, it becomes solid again and maintains the shape of the mold.
Usually the mold is made of two aluminum half shells (obviously the molds can also be made of steel, resin, epoxy resin, etc.). As an alternative to metal molds, molds obtained with 3D printers can be used with excellent results. In this case it will be necessary to use resins suitable for high temperatures. A lot of documentation on this topic with various examples is available on the web.
In addition to offering lower system costs than other manufacturing processes, this system offers ease of use, wide availability of raw materials easily available on the market and the possibility of producing parts with recycled material, for an even more productive, economical and more ecological solution!
The system is the ideal tool for prototyping, research and development, and production runs.
Much care has been taken to ensure operator safety by ensuring that the system will not start unless the safety grille is lowered, while also ensuring versatile and easy operation.
Injection molding is perfect for a variety of uses within industries such as electronics, jewelry, model making, and medical device manufacturing, and other specialized applications that require many small plastic parts.
