...of smaller moulds, lower locking forces, and even smaller machines in some cases. Hot-Runner Stack Moulds for Families of Moulds. In the case of hot-runner stack systems with an offset spruebar, the melt can be fed eccentrically. This “swan neck” is ideal for large, two-dimensional parts that do not permit central passage of the sprue bar (Fig.4). Robot access is also easier, since the swan neck is placed so as not to interfere with handling of the parts. Husky offers hot-runner systems with th...

...ctric servo drives are gradually replacing pneumatic drives (Fig.1). The sum of the experiences in small, high-speed and medium-sized injection moulding machines has taught us that a linear unit can remove a part in a shorter time than a swan-neck unit, provided that ejectors or cores present the part in an open way for transfer. With larger machines and injection moulded parts, demoulding is often more difficult. The advantage of a short removal time is becoming less important. Swan-neck robots...

...Reis Extrusion, which emerged from the former Gepoc Verfahrenstechnik. Reis Extrusion extrudes thermoplastic elastomers and, as a process specialist, complements the expertise of Reis Robotics. In the rest of its exhibition program, Reis presents swan-neck robots for rapid assembly and handling of parts directly on the production machine, and a retouching press for optimizing molds and dies. Cost and time savings in programming and simulation are promised by ABB Automation GmbH, Friedberg, Germa...

...;In 2000, therefore, we invested in the first robot-aided plant. Despite many good offers for conventional solutions, we therefore decided in favor of using six-axis robots." Parts Removal and Quality Removal in One Operation Some 19 swan neck robots (manufacturer: Kuka Roboter GmbH) are now used on the 80 injection molding machines in the company’s manufacturing shop. Bauser chose a locally based partner to implement the automation project: SHL Automatisierungstechnik AG, Böttingen, Germa...

...me standard machines, Ettlinger also designs and builds one to three custom machines per year for manufacturing particularly large, heavy plastic parts – tailored to specific customers and products. The system, delivered in August 2008 with a swan-neck robot for part removal, measures 11.9 × 3.2 meters and therefore requires less space than conventional machines of this clamping force class. Construction of the special machine took eight months from design to delivery. After a comprehensive test...

...s produced from a 30 % short glass fiber-reinforced polyamide (PA6-GF30). In parallel, in the second stroke, dam elements are molded on with a thermoplastic elastomer (TPE), and bellows seals for the ventilation are created. In parallel, a swan-neck robot removes the parts at the 270° mold position and transfers them to the assembly station, where the eleven assembly clips are fitted by two more robots, including laser monitoring. The hot-runner systems of PA6-GF30 and TPE are very effectively t...

...workflow. With such a combination, there is the added advantage that a control system for linear robots developed by Sepro Robotique, La Roche-sur-Yon, France, can be used, with which the user can also operate and program a swan-neck robot. Energy Efficiency of Automation Solutions A still relatively new topic for injection molding and robot manufacturers is the energy efficiency of the systems. Most of them have long regarded “green automation” as making an important contribution to the efficie...
