K 2016: Balances out process fluctuations before rejects are produced

Producing moulded parts of a consistently high quality shot by shot is the aim of every injection moulder. Simply using a precise injection moulding machine will not achieve this, however. Even minor changes in ambient conditions or in raw materials and wear have an effect and can mean that parameters need to be readjusted. more...

Current 3D printing technologies use glass, metal, plastic, synthetic resin or ceramics as starting materials. What was missing was a process for silicone elastomers – that is, until now. WACKER has developed a 3D technology that makes it possible to build three-dimensional silicone objects for the first time. (Photo: Wacker Chemie AG)

Schicht für Schicht zum elastomeren 3D-Objekt

Additive Fertigung mit Silikon

3D-Druck ist eine Trendtechnologie, die für Produktentwickler besonders interessant ist. Doch die Palette der Materialien ist begrenzt. Bisher lassen sich vor allem Kunststoffe und Metalle drucken. Nun steht ein Verfahren zur Verfügung, mit dem sich auch Objekte aus Silikon im 3D-Druck fertigen lassen. Schicht für Schicht setzt ein Roboter aus einer Düse winzige Tröpfchen nebeneinander ab. Anschließend wird das Silikon mit ultraviolettem Licht vulkanisiert. Dabei entstehen homogene Körper mit einer nahezu glatten Oberfläche. Das Material ist biokompatibel, temperaturbeständig und transparent. Damit eröffnet das Verfahren neue Anwendungsfelder in den Industriebereichen Automobil, Medizin, Haushalt und Optik. Nach Meinung der Rohstoff- experten ist der 3D-Druck mit Silikon ein riesiger Markt. more...

Automated Production of Pharmaceutical Rubber-Stoppers

Pharma Challenge

The challenge consited in providing a turnkey solution for the production pf pharmaceutical stoppers in injection molding machines in a controlled atmosphere. The goal of the fully automated solution with integrated robot for the stripping of the parts was to produce 240 million stoppers of a diameter of 13 mm per year. The injection-compression molding solution by REP consists in producing the stoppers on two fully automated CMS-type machines equiped with eight molds of 413 cavities. The solution enables the user to produce 41,880 parts/hour with a machine cycle of 71 sec. The automated system reduces waste and costs. more...
