N&H technical testing and analysis laboratory
Tests and measurements for electromechanical components
In our laboratory in Willich we offer the possibility of carrying out technical tests and analyses close to the customer. 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 are 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.

We offer the following exams
Electromechanical testing
- Force-displacement characteristics of control elements
- Service life of controls
- Abrasion resistance of painted and printed surfaces
- 2D / 3D measuring microscope for assessing surface structures and geometric measurement of components (new 3D measuring device Scope Check)
- Pressure / tensile force meter for checking the strength of material connections, actuating forces on operating elements (buttons, switches) and the pull-off force of foils and films.
Optical test
- Optical inspection with stereo microscope
- luminance
- color coordinates
- Color measurement with a sphere spectrophotometer
- 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.
More exams
- Climate test in a climate chamber (temperature -70°C to +180°C / humidity 10% to 98%)
- cable tester
- Jig construction with CNC engraving and milling machine
prototyping
In order to provide our customers with extensive support in the early concept development phase as well as in the testing of their designs, we have several 3D systems 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 2 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.
