construction
Our product designers support you from the concept phase through to series development. We can do both individual components, such as silicone keymats, membrane keyboards and various molded parts, as well as the complete control unit design according to your ideas or revise the design or construction of existing products.
You decide whether you want to use the development and design work as an individual service or whether we will accompany you in further steps up to series delivery.
- Sketching, conception, planning and pre-construction
- Construction in 3D CAD
- Display of product views in the form of realistic 3D renderings
- Creation of production documents such as technical drawings and parts lists
- Creation of prototypes using 3D printing & silicone casting
Prototype construction with 3D printer
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. In addition to production, we also take care of the construction of your prototypes and molded parts.
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.
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:
- Support from design to production
- Fast and cost-efficient prototype production
- Wide variety of materials for individual requirements
- Precision and reliability at every print
Professional logistics
We take care of the complete transport and customs clearance of your goods.
Establishment of a buffer store
For items with regular, predictable requirements, we offer the option of setting up a buffer storage at our siteFrom the arrival of the goods in Willich, you will have flexible retrieval options with short delivery times and low supply risk over the entire term.
Other advantages are:
- Cost advantages higher production volumes and lower transport costs.
- reduction of storage costs with you
- fixed price of the ordered goods for the agreed storage period (max. 12 months)
- Reduced capital commitment
We would be happy to discuss various delivery scenarios with you in order to meet your needs on time and economically.
Outsourcing options for supply chain activities in Asia
In addition to the production of electromechanical components and complete solutions, we also offer outsourcing options as a service for your purchasing. We offer our medium-sized customers in particular the option of safely and reliably outsourcing existing simplify supply chains and streamlining purchasing structures.
Supply chain activities in Asia are high infrastructure and personnel costs Such operating and capital costs can quickly add up and significantly impact the profitability of a product. Benefit of our years of experience on the Asian market and our comprehensive supplier network in India, Taiwan, Vietnam and China.
You get a keyboard from us, but the display comes from supplier X in Taiwan and the injection molded housing from supplier Y in China? Why not purchase all components from N&H?
Our outsourcing solution for medium-sized companies:
- German contact person and a German GmbH as contractual partner
- We take over the auditing of the suppliers, the procurement of your components and the complete logistical handling
- Sound technical advice from our team of engineers in Willich
- Efficient communication from our Asian colleagues in Germany and our team in Shanghai
- Our warehouse in Germany offers you flexible delivery schedules, as well as savings potential through economies of scale and optimized freight costs
- On request, we also offer alternative suppliers and optimize your supply chain
N&H laboratory
In our laboratory we offer the opportunity to carry out technical tests and analyzes as a service. The tests and measurements on our own products are free of charge for our customers.
On request, we are also happy to carry out technical analyzes to solve problems with third-party products, which we charge at cost.
We offer exams in the following areas:
- Electromechanical Tests
- Optical / acoustic tests
- Materials exams
- Measurements surface resistance, volume resistance, conductivity
- Technical problem analysis, also for third-party products
We offer you a selection of samples to help you make targeted product decisions and find the optimal solution for your requirements.
keyboard pattern
Our keyboard sample set is a valuable tool for anyone working on the development of high-quality input systems. It contains a sample silicone keypad with numerous example keys and design variants, as well as a sample membrane keyboard that offers various equipment options. With these components, you can get to know and experience the diverse design and functional possibilities of our products up close.
