Innovationsprojekt „IMC-Seal3D“ – Nachbearbeitungsfreie Sichtbauteile im PUR-IMC-Verfahren
Im Polyurethan-In-Mold Coating (PUR-IMC)-Verfahren werden hochwertige Sichtbauteile direkt im Spritzgießwerkzeug mit einer kratzfesten, dekorativen Oberfläche versehen. Eine zentrale Herausforderung ist dabei die zuverlässige Abdichtung der Kavität: Aufgrund der sehr niedrigen Viskosität des Polyurethans stoßen konventionelle Abdichtungskonzepte an ihre Grenzen. Die Folge ist bislang eine Abdichtkante am Bauteil, die eine zusätzliche Nachbearbeitung erforderlich macht. Im vom Bundesministerium für Wirtschaft und Energie geförderten Kooperationsprojekt „IMC-Seal3D – Etablierung eines flexiblen Abdichtsystems für polyurethanüberflutete Sichtbauteile“ hat ein Konsortium bestehend aus der Neue Materialien Bayreuth GmbH (Projektleitung), Pakulla GmbH, MURTFELDT GmbH & Co. KG, Heraeus Amloy Technologies GmbH sowie Forvia Hella ein neuartiges, flexibles Werkzeugabdichtungssystem entwickelt. Ziel war die Realisierung einer kavitätsbündigen, prozessstabilen Abdichtung, die sowohl kleine Geometrien als auch komplexe 2D- und 3D-Bauteile sicher beherrscht und damit den Nachbearbeitungsschritt vollständig überflüssig macht. Hierzu wurden innovative Dichtwerkstoffe wie amorphe zirkoniumbasierte Metalllegierungen sowie Hochleistungsthermoplaste wie PEEK untersucht und unter industriellen Bedingungen hinsichtlich Dichtwirkung, Lebensdauer und Prozessstabilität optimiert. Als Demonstrator wurde erfolgreich eine Abdeckung für eine Fahrzeuginnenraumleuchte umgesetzt. Die Ergebnisse zeigen: Mit dem entwickelten System ist erstmals ein PUR-IMC-Prozess realisierbar, der ohne nachgelagerte Bearbeitungsschritte auskommt. Damit wird die Prozesskette deutlich verkürzt, die Fertigung effizienter gestaltet und die Kosten reduziert. Gleichzeitig eröffnet das Verfahren neue Anwendungsmöglichkeiten für hochwertige Sichtbauteile in der Automobilindustrie, im Consumer-Bereich und in der Elektronikfertigung.

Bergischer duck brooding basket
We built the precision injection molding tool for the Bergisch duck brooding basket, which provides a protected place for ducks and other animals such as owls, hedgehogs, and kestrels. The basket, made from recycled plastic, protects against predators and the weather and is particularly easy to assemble thanks to two half-shells that are connected with seven high-quality V2A connecting screws. With our tool, we are helping to produce this sustainable and animal-friendly solution in high quality.

Conformal cooling
In contrast to conventional drilling cooling, contour-close cooling channels run close to the geometry along the cavity. Targeted heat dissipation enables a homogeneous mold temperature and significantly shortens the cooling phase. This method is particularly worthwhile for complex component geometries, tight tolerances, visible surfaces, and materials with challenging thermal behavior. In addition to improving quality, cycle times can be reduced and process stability and tool performance can be sustainably improved.

Maximum travel distance for milling (3-axis) 1,350 x 900 x 800 and (5-axis) 1,050 x 900 x 600

In-house electrode production
Maximum precision thanks to the latest electrode technology Our electrode technology is a key component for the precision and quality of our work. We rely almost exclusively on graphite electrodes because they guarantee the highest processing speed and excellent precision. We only use copper electrodes in exceptional cases. With our fully automated Chameleon production line, we produce all electrodes entirely in-house. For this purpose, we have purchased two specially designed Röders milling machines, which impress with their maximum precision and efficiency. This modern equipment enables us to meet even the most demanding requirements of our customers - with precision, quality and reliability.

Milling with the highest precision
Precision and efficiency – our machinery We rely on the latest technologies to ensure the highest precision and efficiency in production. Our machinery includes a total of 9 high-performance processing machines: Milling machines: 4 three-axis and 2 five-axis milling machines for machining complex geometries. EDM machines: 3 sinking EDM machines and a CNC wire EDM machine for the finest contours and details. Grinding machines: 2 precision surface and profile grinding machines for perfect surface quality. Laser technology: An Alpalaser 120 for precise laser welding, ideal for repairs and modifications. With this equipment, we are able to meet even the most demanding requirements in the tool and mold making industry. See for yourself our know-how and our passion for precision – we look forward to getting to know you!

Mold design
The design of an injection molding tool begins with precise 3D modeling of the mold in Cimatron. This powerful CAD/CAM system enables the detailed elaboration of complex geometries and the efficient planning of all tool components. The injection molding process is then simulated using CadMould to analyze and optimize filling behavior, cooling, and potential sources of error at an early stage. This enables us to ensure high quality, functionality, and cost-effectiveness of the mold even before production begins.
