Technical injection molding
ARBURG injection molding technology enables you to produce technical components at competitive unit costs. These videos show a broad range of applications – from micro injection molding and complex mold technology through to automation and complete turnkey systems, which we supply as a primary contractor.
Head module produced on flexible production cell
For the production of the head module of an optical motion detector, a production cell with manual loading of the part magazine is the optimum solution in terms of flexibility, capacity utilization, quality and costs. The cycle time is around 43 s and offers sufficient scope for additional manual tasks.
At the center of the ARBURG project facility is an electric ALLROUNDER 470 A with a clamping force of 88 tons and a 6.1 oz injection unit. Two injection modules with screw diameters of 25 mm and 35 mm are available to achieve different shot weights. The highly flexible production cell alternately manufactures front and bottom lenses, as well as head modules on seven injection molds. The modules are produced in 42 versions. Handling is performed by a vertical MULTILIFT V robotic system configured in a task-oriented manner. The lower gripper part is used for the heads and the upper one for the lenses.
Shot weights of a few milligrams
Precision small parts, such as micro counter wheels weighing only 0.004 g, can be produced to a high standard on optimized ARBURG standard machines. A special micro-production cell enables us to offer you an efficient solution for shot weights measured in milligrams.
Dynamic injection using a position-regulated screw, for example, ensures the required precision and compliance with tolerances in the micron range. An electric ALLROUNDER 270 A injection molding machine is used with a 0.1 oz micro-injection unit. Part handling is via a horizontally-operating MULTILIFT H 3+1 robotic system.

New dimensions: individualized plastic parts
Production efficiency can be enhanced through the process integration of upstream and downstream production steps. One example is the flexible inline printing system using the InkBOT process, which ARBURG and FPT Robotik presented to the international trade public for the first time in 2012.
The production cell manufactured individualized name plates. The new InkBOT process combines digital printing and robotics. By means of inline printing, it is now possible to exploit the benefits of digital print in the high-speed sector, even in the case of free geometries in industrial production processes. Fast, flexible, borderless and individualized printing is even possible on curved plastic parts immediately following injection molding during the manufacturing process.
Complex core pull technology
In order to produce a Y junction for a sewage pipe with a diameter of 110 mm, a mold featuring complex core pull technology and collapsible core segments is used. The three hydraulic core pulls are fully integrated in the SELOGICA control system.
A sequence with synchronized side cores prevents damage to the mold; the main core moves separately and always ahead of the side cores. The pipe junction is produced on a hydraulic ALLROUNDER 820 S injection molding machine. A MULTILIFT SELECT robotic system ensures gentle removal of the component, which weighs 505 g.
