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 realize:

  • Protective covers for input devices
  • Rubber seals and rings
  • Grommets, flanges, 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.

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

Silicone Covers

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 rubber-metal connections for industrial use

We can supply you with machined metal components in an elastomer composite.

The 2K components are suitable for a variety of applications in which a plastic base with overmoulding TPE is out of the question. Examples include sealing elements in mechanical and plant engineering, shock absorbers in the automotive sector or transport rollers in industry.

The basis for these components is a milled metal component (e.g. stainless steel, aluminum-zinc or copper alloys), which is firmly bonded to the elastomer. Common materials include silicone, EPDM, NBR etc.

Different color and hardness variations of the soft component lead to numerous variants. In this way, the requirements of customer-specific applications can be taken into account. For example, by selecting suitable elastomer materials to counteract premature abrasion or to implement certain damping characteristics. The milled metal base allows classic shaft-hub connections or screw threads for connection to peripheral elements.

We advise you comprehensively on the selection of materials and design of the contact areas especially for your project.

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.  




On the basis of your sample, your specification or technical drawing, we will create an individual offer and support you during the project.

We advise you on the selection of suitable materials and offer cost reduction options. We offer you an active co-operation in the development and construction and give suggestions for improvement.

For a technical consultation please contact us by phone: +49 (0) 2154 – 81250. Also a personal meeting in our office or at your place is possible by appointment.

For an offer we need:

  • technical drawing, sketch or pattern
  • technical specifications, equipment extras
  • required amount
