Combined with polymers for the first time
AMM at K 2019: combined with polymers for the first time
Der Mehrkomponentenspritzguss verzeichnet wachsende Marktanteile – ein Trend, der sich auch weiterhin dynamisch entwickeln wird. Überproportional wachsen Mehrkomponentenanwendungen mit Silikon. Die Gründe hierfür liegen in den besonderen Materialeigenschaften, der sehr guten Verarbeitbarkeit im Spritzguss und der steigenden Zahl geeigneter Materialpartner. Auf der K 2019 in Düsseldorf präsentiert Engel erstmals die Kombination von Flüssigsilikon mit amorphem Metall und eröffnet damit vor allem im Hightech-Sektor neue Horizonte. more...
Sinnvolle Zusammenführung von Automatisierung, Digitalisierung und Prozesssteuerung
Digitization for less Complexity and more Sustainability
Die Zunahme von Komplexität, Flexibilität, Volatilität, sich verkürzender Planungshorizonte, Geschwindigkeit, Präzision und Qualität, setzen bisherige Geschäfts- und Methodenmodelle einem Stresstest und mit teilweise hohem Tempo anzugehenden Veränderungen aus. Das Unternehmen Desma bietet durch die sinnvolle Kombination von Maschinenanwendungen mit digitalen Werkzeugen die Voraussetzungen dafür, dass sich die Elastomerverarbeiter im Wandel der Zeit weiterhin wettbewerbsfähig positionieren können. more...
