Virtual design specialist Sigma Engineering GmbH is introducing its latest interactive platform, SIGMAinteract during at K 2019 in October in Düsseldorf, Germany.
SIGMAinteract software enables the visualisation of information exported from Sigmasoft, the company’s virtual modelling software. The new tool allows users to share Sigmasoft results interactively and in 3D with colleagues, project partners and customers, thus contributing significantly to "a good interdisciplinary exchange,” the company said in a 5 Aug release ahead of the show.
A live demonstration of the new SIGMAinteract software will be shown at the company’s booth at K2019, where the company’s “Pot Cloth” project - developed in collaboration with Momentive Performance Materials GmbH, Germany, EMDE MouldTec GmbH, Germany, Wittmann Battenfeld GmbH, Austria, and Nexus Elastomer Systems GmbH, Austria - will provide an example of its possibilities.
Visitors to the booth can watch the virtual and actual production of the product - an LSR potholder made from Silopren LSR 2640 supplied by Momentive Performance Materials. The potholder will be moulded on a SmartPower 90/350, control Unilog B8, from Wittmann Battenfeld, using an LSR injection moulding tool and cold runner system built by EMDE MouldTec. the system is completed by a ServoMix X200 dosing system from Nexus Elastomer Systems.
In this project, part design and tool construction were done in parallel, making it necessary for the partners to work closely together.
Sigma conducted two virtual Designs of Experiments, for the validation of the part design and the evaluation of the heating concept. The Sigmasoft results showed that the honeycomb structure of the part placed high requirements on the material and the tool, with a high risk of air entrapment at the weld lines of the comb walls and premature curing during filling.
With the help of the Sigmasoft simulations, the ideal length and power of the heating cartridges needed to achieve an even temperature distribution in the cavity area could be determined.
The two DoEs provided the insight needed to build a mould that incorporated solutions to these challenges: a venting system was implemented into the tool, premature curing was prevented by choosing the appropriate material and the part could also be scaled up. The hanger - the part that determined the cycle time - was redesigned, allowing the heating time to be reduced by five seconds.
At K2019, Sigma Engineering can be found in hall 13 at booth B31.
