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.

prototyping
We provide you with comprehensive support in the development and production of your prototypes. With our powerful 3D printing systems and our expertise in the design of molded parts, we offer precise, reliable and economical solutions for your projects.
High-precision 3D printing solutions for prototypes
Our 3D printing technology enables the production of high-quality prototypes with a maximum print size of 355 x 254 x 355 mm and an accuracy of ± 0,2 mm. Thanks to a wide range of materials, including ABS, ASA, PLA, TPU, PC-ABS, ABS-ESD7 and the chemical-resistant PA6.6 MF07 (Diran), we can adapt prototypes individually to the requirements of your projects. This variety of materials enables the production of components with special properties such as high impact resistance or wear resistance.
Efficiency and versatility
Our 3D printing systems offer:
- Versatile material options for the production of functional prototypes and components.
- Flexible layer thicknesses between 0,127 mm and 0,330 mm for customizable detail and strength.
- Large format printing options, ideal for producing complex or large-scale prototypes in a single print run.
construction and development
In addition to manufacturing, we also undertake construction of your prototypes and molded partsOur experienced team develops tailor-made solutions that are precisely tailored to your requirements. From the initial idea to the final implementation, we accompany you through all steps of development.
Fast and precise resin 3D printing
For particularly detailed prototypes, we use resin 3D printing systems that impress with their high resolution and precision. This technology is particularly suitable for delicate models or the simultaneous production of several components, which enables short production times.
The advantages at a glance:
- Fast and cost-efficient prototype production
- Wide variety of materials for individual requirements
- Precision and reliability at every print
- Support from design to production
