Rubber parts and silicone parts have many positive properties, such as high elasticity, good resistance to heat and cold, high chemical resistance, good aging resistance and high tear strength. These properties make silicone molded parts very versatile.
We manufacture custom rubber parts, silicone parts and elastomer composite parts. We can already help you with this small and medium quantities offer attractive conditions. Our dedicated team will provide you with comprehensive advice on the selection of the optimal material that will withstand the requirements of your functional description, temperature resistance, chemical resistance, weather influences and load.
For an individual offer, we need either a technical drawing of your component or an existing sample. However, if you do not yet have such a template, our product designers will be happy to design and develop a suitable molded part for you.

Silicone protective covers
Covers made of silicone offer many advantages. They protect the hardware from dirt and scratches, reduce damage in the event of a fall and provide a better grip.
We ask custom protective cases made of silicone or LSR of different hardnesses (Shore A40 - A70). Depending on the application, an additional PU coating can be applied. Thanks to lettering, different colors and specific markings, the silicone cases also have a high level of customization. The silicone cases are adapted to the existing case.
Service
Our product Designer support you in Mechanical Design a silicone cover. The prerequisite is an existing 3D file of the handset or a reference sample. Of course, we also manufacture custom plastic housing.
Advantages
Protective cases made of silicone offer many advantages:
Durability: Silicone is a very resistant material and offers excellent protection against bumps, scratches and other damage.
Flexibility: Silicone is a very flexible material that adapts well to the contours of the protected object. As a result, it offers a tight fit and better protection.
water resistance: Silicone is water-repellent and can therefore offer good protection against water. This is especially important for electronic devices such as smartphones and tablets.
heat resistance: Silicone can withstand high temperatures without melting or deforming. This makes it a suitable material for use in high temperature environments.
Lightweight: Silicone is a lightweight material and therefore adds little extra weight to the protected item. This makes it particularly useful for use with portable devices such as cell phones and laptops.
Realized protective cases
Multi-component injection molding
The Multi-component injection molding makes it possible to combine the positive properties of plastic and elastomer or metal in one component. This opens up a wide range of application examples.
Elastomer molded parts and plastic often appear together where the properties of a single component are not sufficient. The hard component to absorb mechanical loads, the soft component as a seal, protection or damping. In a large number of cases, two separate components are designed for this. This leads to additional investment and effort in production and quality assurance, which can, however, be reduced through clever design in the development phase.

Molding of magnets with silicone
The integration of silicone coating and magnets creates innovative and versatile products. A striking example of this is our recently produced silicone bracelet with integrated magnets.
The positioned magnets are evenly spaced in the bracelet, making it easy to put on and take off the tracking watch for almost all wrist widths. This targeted placement ensures comfort and adaptability in everyday use.
The silicone coating acts as a protective shield for the magnets and protects them from moisture, dust, chemical influences and mechanical stress. This robust protection mechanism ensures that the magnets can maintain their optimal performance and durability. In addition, the silicone can be easily cleaned and disinfected, which is particularly advantageous in times of increased hygiene requirements.
Also worth emphasizing is the critical role of temperature control in the overmolding process. Accurately controlling temperatures ensures that the silicone precisely cures and takes on the desired properties. This is essential as excessive heat can affect magnetism, while too low temperatures could result in incomplete curing.
With our many years of expertise in the field of silicone technology, we are very familiar with this technology and look forward to realizing innovative products with overmoulded magnets for you.
Our product designers support you from the concept phase to the series development of customer-specific rubber parts and silicone parts. We can construct individual components as well as the entire product according to your ideas or revise the design or construction of existing products.
You decide whether you development and construction work as an individual service or we can accompany you in further steps up to series delivery.
This is how we start your project
In order to make you an initial offer, we need the following information:
- A technical drawing, sketch or sample of your product
- Technical Specifications
- Information on desired equipment extras
- required quantity or your annual requirement
To protect your data and ideas, we can conclude a non-disclosure agreement (NDA) in advance. If you do not have your own NDA, we will be happy to provide you with our template available.
Contact us under info@nh-technology.de. We look forward to your inquiry.

3D printer prototypes
In the field of prototyping using 3D printing, we have been working with well-known providers for years. To expand our range of services, we now offer the creation of prototypes in-house.
With the Stratasys F3 370D printer, we produce prototypes and devices made of real plastic up to a size of 355 x 254 x 355 mm with an accuracy of ±0,2 mm. In addition to the materials ABS, ASA, PLA and TPU, the materials PC-ABS, static-dissipating ABS-ESD7 and robust and chemical-resistant PA6.6 MF07 (Diran) can also be processed. With two print heads, the F370 is able to print the product material and the soluble support structures at the same time. The support structures are washed out in a subsequent ultrasonic bath without manual removal.
Example of a prototype creation in the 3D printer
We design and manufacture custom silicone parts, rubber parts, elastomer parts, multi-component injection molded parts, injection molded parts, plastic parts, molded plastic, rubber, metal and glass parts.
