DUESSELDORF, Germany—K 2019 was a showplace for liquid silicone rubber, with companies highlighting new machinery, materials, tooling, molding and simulation technologies.
Here's a look at some of the technologies showcased.
- Nassau, Germany-based EMDE MouldTec GmbH showed off its capabilities by molding LSR cookie forms on a horizontal Engel injection molding machine.
- EMDE MouldTec supplied a hot runner mold for yellow LSR potholders that were molded by Aachen, Germany-based Sigma Engineering GmbH in Silopren LSR 2630 from Leverkusen-based Momentive Performance Materials. The demonstration used a SmartPower 90/350 injection press from Kottingbrunn, Austria-based Wittmann Battenfeld GmbH. Sigma made simulation studies, applying virtual design of experiments, for the 83-gram potholders, the mold tool and the molding process with Sigmasoft Interact software, overcoming challenges of mainly 1-mm wall thickness over most of the part and flow length up to 135 mm.
- Sigma also simulated rheology and flow for a "Butterfly" cell phone and navigation device holder for horizontal or vertical mounting on automotive interior ventilation grilles. NDU New Design University in Sankt Poelten, Austria, designed the part, as molded by Momentive Performance Polymers in transparent Apec 1745 polycarbonate from Leverkusen, Germany-based Covestro A.G. and Silopren LSR 2759 black adhesion optimized primerless LSR.
- A Wittmann Battenfeld SmartPower 120/130H/130S Combimold multicomponent injection molding machine molded the part with 40 seconds cycle time.
- Elmet also showed butterflies at its booth, as it supplied the 1+1-cavity cold-runner mold tool and TOP 5000 P mixing and dosing equipment for them. Hot runners for the Apec 1745 component came from Luedenscheid, Germany-based HASCO Hasenclever GmbH + Co. K.G.
- Elmet's work is progressing on development of an electric drive TOP 5000 P dosing system, starting with a redesigned pump group, to be followed by a full electric drive "E" version. TOP 5000 P includes Industry 4.0 capability with VNC (Virtual Network Computing) and OPC-UA (Open Platform Communications - Unified Architecture) interfaces for data exchange with injection molding machines. A new email and remote access interface comes within a Premium Connectivity Package as from December 2019, enabling automatic messaging in the event of breakdowns or drum-change needs.
