Digital Aids for Injection Molding

Arburg at the Fakuma 2018

The Gestica control – one stage of the journey toward the digital future of plastic parts production (© Arburg)

With six injection molding machines on its fair stand and nine more on partner stands, Arburg GmbH + Co KG of Lossburg, Germany, is showing the way to digital and highly automated injection molding production. The focus is on "smart" machines that monitor their processes, regulate them adaptively, and actively support the operator. Information technical networking of production is realized with the aid of Arburgs host computer system (ALS). An ambient of "augmented reality" and a new customer portal strengthen service offerings. As an eye-catcher, Arburg is presenting its exhibits in a new mint green/light gray/dark gray color design for the first time.

In sharp focus are the six assistance systems introduced during the recent technology days in Lossburg. They support the machine operator during setup, when entering processing parameters, and for optimizing the process (4.set-up and/or 4.optimisation). In addition, the process startup can be organized more efficiently (4.start-stop), and both quality and process monitoring can be improved, as well (4.monitoring). Experienced operators get more freedom to program functions (4.production), and customer service via online-support has been improved by enabling Arburg technicians to directly access the machine control (4.service), for example. This is mainly realized by a new, cloud-based customer portal that makes various services available via central applications (Apps), such as "machine overview" and "replacement parts catalog".

For data recording and archiving, as well as to visualize the entire process, the injection machine manufacturer Arburg is announcing a new solution: the Arburg Turnkey Control Module (ATCM). This data collector for complex turnkey systems is demonstrated on an Allrounder 470 A electric injection molding machine with 1000 kN locking force that produces two housing parts of a level in a family mold. In addition to automatic assembling, the production cell performs several testing steps and also labels the levels with a QR code. Via OPC-UA interfaces, the ATCM collects information from the injection process and the camera tests and assigns it to the individual part via the QR code. The visitor can read out the corresponding process data on a smartphone on a part-specific website.

Arburg demonstrates (as it did last year) how individual customer wishes can also be included online in a running injection molding process using elastic wire ropes as example. In this fair application, the visitor can choose between different versions and have his order entered directly on a terminal. In the next step, the desired version is produced without a setup step on an Allrounder 375 V vertical machine.

On exhibit for the first time is a special "packaging" version of the Allrounder 320 H hybrid machine in new design and with Gestica control (Fig. 3). The machine boasts 3700 kN locking force plus a modified injection unit and is configured for fast-running applications in the packaging industry. Thanks to specially adapted valve technology, it achieves greater dynamics and reproducibility. Moreover, injection speeds of up to 500 mm/s are possible. At the Fakuma, thin-walled containers (capacity 500 ml) will be produced in a 4-fold mold and labeled in-mold (In-Mold Labeling) during production. One cycle lasts approx. 3.8 s.

Arburg continues to emphasize the processing of fluid silicones. In an injection molding production cell, an Allrounder 270 A electric machine with 350 kN locking force will demonstrate the production of micro-parts in the case of a 38 mg heavy slit valve. First the fluid silicone is mixed in a cartridge and then it is injected into a 4-fold mold by a micro-injection unit (size 5) with an 8 mm screw.

One machine, an Allrounder 570 E Golden Electric with 2000 kN locking force, is dedicated to precision injection molding. The demonstrator, a technical housing part that holds optical components, is produced in a cycle time of 55 s.
