Rubber & Silicone Parts

We manufacture customer-specific molded parts made of rubber, silicone and elastomer composite parts in small and large series production according to your sample or drawing.

Molded rubber parts are generally characterized by their good formability, chemical resistance, pressure and abrasion resistance and good electrical properties.

We advise you in detail on the selection of the suitable material, with a view to the functional description, temperature resistance, chemical requirements, weather influences and resilience.

Our molded parts are used in all industries, such as the automotive industry, medical technology, mechanical engineering and electronics industry.


We process all common materials in different hardnesses (ShoreA):

  • Standard materials such as NR, NBR, BR, EPDM, CR etc.
  • Elastomers: ACM, CSM, FPM, HNBR etc.
  • LSR – liquid silicone rubbers
  • TPE, TPU molded parts
  • Thermoplastics
  • Rubber-metal connections
  • Rubber-plastic connections
  • Customized special mixtures


We realize:

  • Protective covers for input devices
  • Seals, rubber seals, rings, rubber rings
  • Grommets, flanges, bellows bellows
  • Form Tubes
  • Rubberized rollers
  • Rubber damper
  • Rubber positively connected parts
  • PU molded parts (e.g. wheels and rollers)
  • Combined rubber-metal parts
  • Combined rubber-plastic parts
  • etc.

Silicone covers offer many advantages to a handheld device. They protect the hardware from dirt and scratches, reduce damage and also the risk of slipping out of hand. N & H Technology produces customer-specific silicone or LSR protective covers of various hardnesses (Shore A40 - A70).

Depending on the application, an additional PU coating can be applied. The silicone covers are adapted to the existing housing and have a high customizability by the possibility of OEM lettering and specific markings.

Our  engineers  help you to design a silicone cover for your hardware. Prerequisite is an existing 3D file of the handheld device.


2K Gummi-Metallverbindungen für die industrielle Anwendung

Spanend bearbeitete Metallkomponenten im Elastomerverbund eignen sich für vielfältige Anwendungen bei denen eine Kunststoffbasis mit Overmoulding TPE nicht in Frage kommt. Beispiele hierzu sind Dichtelemente im Maschinen- und Anlagenbau, Shock-Absorber im Automotive Bereich oder Transportrollen in der Industrie.

Grundlage bildet bei diesen Bauteilen eine gefräste Metallkomponente (z.B. Edelstahl, Aluminium- Zink oder Kupfer Legierungen), welche stoffschlüssig mit  dem Elastomer verklebt wird. Gängige Materialen sind beispielsweise Silikon, EPDM, NBR etc.

Verschiedene Farb- und Härtevariationen der weichen Komponente führen zu zahlreichen individuellen Varianten die mit einem Werkzeug gefertigt werden können. Durch die vielfältigen Kombinationen im Materialmix kann gezielt Rücksicht auf die Anforderungen der kundenspezifischen Anwendungen genommen werden. Beispielweise durch die Auswahl geeigneter Elastomer-Materialien um vorzeitigem Abrieb entgegenzuwirken oder bestimmte Dämpfungscharakteristiken zu realisieren.

Die gefräste Metallbasis erlaubt klassische Welle-Naben-Verbindungen oder Schraubgewinde zur Verbindung mit Peripherieelementen. Wir beraten Sie umfassend zur Auswahl der Materialien und Ausgestaltung der Kontaktflächen speziell für Ihr Projekt. Gerne bewerten wir Ihre Anfrage und stellen Ihnen sinnvolle Realisierungsmöglichkeiten gegenüber.

In-House 3D Prototyping


Prototypen mit Formlabs In the field of prototyping via 3D printing, N&H has been working with well-known suppliers for many years. To extend our services, we now offer prototyping in-house. With a new 3D printer of the stereolithography technology (SLA) we offer our customers further support in the development process. In SLA technology, liquid resin is cured layer by layer using a UV laser. The individual layer thickness can be varied in the range of 25µm – 100µm. In addition to verifying the dataset, we can now independently support our customers in the early stages of development. These include collision checks, assembly samples, pilot series, etc.
