Arburg/NPE Plastics innovations in action and an American premiere
At NPE, Arburg will present the hybrid Allrounder 1120 H with a clamping force of 6,500 kN, a new design and a Gestica control system to an American audience for the first time. In addition, the company will present innovative technologies and applications for plastics processing.
Friedrich Kanz, Managing Director of Arburg USA, explains: “Whether additive manufacturing, Industry 4.0 or LSR processing, Arburg is a pioneer in many areas and has decades of know-how in plastics processing. We don't see ourselves as a supplier of machines, but rather as a technology partner that can provide our customers with everything from a single source. Our nine exhibits are designed to showcase an exciting cross-section of our wide range of products and services. At 900 square metres, we enlarged our stand area by nearly 40 percent compared with the last NPE in 2015.”
The hybrid Allrounder 1120 H will be on display for the first time outside Europe at the NPE 2018, where it will be celebrating its American premiere. It extends the clamping force range by 30 percent to 6,500 kN. The new large machine offers a well thought-out design for even more ergonomics and functionality as well as its visionary Gestica control system, which offers the same look and feel as smart mobile devices. The exhibit will demonstrate Arburg's expertise using the example of the well-known folding step stools. The eight individual parts from PP are handled by a Multilift V 40 linear robotic system and then combined within the injection moulding cycle with the help of a six-axis robot and assembly station.
Automation and individualisation
To increase added value, a growing number of increasingly complex operations are being integrated into the injection moulding process. Arburg offers a wide range of automation solutions from a single source for this: From simple pickers to six-axis robots and complex turnkey systems, everything is included. All eight Allrounders at the Arburg stand are automated.
Additionally, Arburg will show an LSR/LSR micro-injection moulding application with its tool partner, Kipe Molds. An electric Allrounder 270 A with a size 5 micro-injection unit produces silicone membranes as used in valves for the medical technology or automotive industry. The micro-injection unit is equipped with a special eight-millimetres LSR screw for manufacturing the 0.05-gram LSR pre-moulded part (70 Shore A hardness). A servo-electric injection unit from Kipe Molds integrated into the 1+1-cavity mould and into the Selogica control system is used for the 0.005-gram second LSR component (30 Shore A hardness). A kiki robotic system removes the LSR/LSR diaphragm, feeds it to a camera inspection station, and then places it in a container.
By combining additive manufacturing, injection moulding and Industry 4.0 technologies, high-volume parts can be enhanced and customer requirements integrated directly into the value chain. Arburg will show how such customised individualisation works with an IT-networked and fully automated production line for business card holders. Here, a six-axis robot links injection moulding with additive manufacturing. First, the person's name is entered on a tablet PC. An electric Allrounder 370 E Golden Electric manufactures the moulded part, which is handled by a Multilift robotic system. An individual barcode is applied during the subsequent laser marking step. A six-axis robot takes the card holder and places it in the build chamber of the freeformer. For the automatic opening and closing of the cowl, the freeformer and robotic system communicate via a Euromap 67 interface. The freeformer additively applies the desired 3D lettering from ABS in accordance with the information in the code.
