N&H technical testing and analysis laboratory
Tests and measurements for electromechanical components
In our laboratory in Willich we offer the possibility to carry out technical tests and analyses close to our customers. Our laboratory is equipped with modern technology and equipment to ensure that the tests and analyses are carried out accurately and reliably. The tests and measurements on our own products free of charge for our customers.
On request, we also carry out technical analyses in our laboratory to solve problems with third-party products, for which we charge according to the effort involved.
Further services for our customers >>
We offer the following exams:
Electromechanical testing

- dominant wavelength brightness distribution (homogeneity) of Displays, backlights, backlit keyboards and pictograms etc.
Acoustic test
- sound level measurements
- Recording of frequency response diagrams
material testing
As the exclusive representative of the conductivity measuring devices from Nittoseiko Analytech in the German-speaking area (DA-CH) and the BENELUX region, we also offer the measurement of the surface resistance and volume resistance as a service.

- Jig construction with CNC engraving and milling machine
prototyping
We will support you comprehensively in the Development and production of your prototypes From the initial idea to near-series implementation. With powerful 3D printing systems and in-depth design expertise, we offer precise, economical, and reliable solutions for a wide range of requirements.
Our 3D printing technology enables the production of high-quality prototypes with a maximum build volume of 355 × 254 × 355 mm and a dimensional accuracy of ±0,2 mm. wide selection of materials Using a wide range of materials – including ABS, ASA, PLA, TPU, PC-ABS, ABS-ESD7, and the chemical-resistant PA6.6 MF07 (Diran) – the manufactured components can be optimally tailored to your technical and functional requirements. This also allows for the creation of prototypes with special properties such as high impact or wear resistance.
Depending on the project requirements, we produce in variable Layer thicknesses between 0,127 mm and 0,330 mm, which allows for flexible adjustment of detail accuracy and component strength. The large-format printing capacity allows even complex geometries or larger prototypes to be realized in a single run.
In addition to pure production, we also undertake the Design of your componentsOur experienced development team creates tailor-made concepts that are precisely tailored to your requirements – efficiently and practically.
For particularly delicate or detailed models, we use our resin 3D printing technology. This is ideal for high-resolution prototypes and also enables the parallel production of multiple components with short lead times.
Your benefits at a glance:
- Fast and economical prototype production
- Wide variety of materials for individual requirements
- High precision and reproducibility
- Support with construction, design and implementation
Whether it's a single piece or a small series, we offer a flexible and quality-assured solution for your prototypes. Please contact us to find the right process for your project.
