Wohlrab coating technology - unique and versatile beyond comparison
Conductive or insulating, highly reflective, scratch resistant, biocompatible… and of course economical and durable: Application requirements on coatings are so diverse that there is no such thing as a „one for all“ technology. Wohlrab‘s comprehensive surface treatment portfolio will satisfy your every need - tailored to your specific coating task.
Apart from PVD and PECVD coatings, Wohlrab offers automated robotic painting with connected dust-free chambers, pad printing with up to six colours, nano coatings and plasma treatment. Special coatings for optical and sensor applications as well as biocompatible coatings for the medical field round off our extensive range of surface enhancements. Wohlrab offers two different PVD processes: thermal evaporation and sputtering. That gives you a free hand in designing, and flexibility in selecting the best possible material or combinations thereof for your specific application. And when standard solutions just aren‘t good enough, Wohlrab‘s decades of expertise in the development of coating layers will provide you with the best possible solution for your particular needs. We‘d be delighted to solve your next challenge!
Fixtures and masking are individually developed when only defined areas of a product are to be coated, be it for functional or decorative purposes. We boast our own design and manufacturing workshop. Moreover, our processes and equipment can be customized to even very special requirements.
- Design and manufacturing of tailored fixtures
- Design and production of masking
- In-House design department using Solid Works
- In-House 3-D prototyping
- Wohlrab injection moulding in Indonesia
- Close cooperation with qualified injection moulding suppliers
The profound experience of 40 years in coatings, together with the knowledge and creativity of our engineers, and the continuous investment in state-of-the-art technology allow us to provide solutions far beyond market standards.
Be that the development of coating layers, the combination and/or optimisation of technologies and processes - the comprehensive expertise and decades of experience of our technical staff make us the partner of choice for all aspects of coating technology. We collaborate with a broad R&D network of companies and institutes to stay abreast of state-of-the art technologies and pave the way for tomorrow‘s applications.
Whatever your requirements are - contact us! Consult our developers, physicists and engineers even in the earliest development phase of a project to conduct a feasibility study. On hand of this, we are also in a position to offer alternatives, thereby pointing out your individual benefits. And we‘ll ,hold your hand‘ along the way - until mass production and beyond. Take advantage of our know-how!
The innovative spirit of our company is fuelled by the creativity of our staff and the application of state-of-the art equipment. This enables us to exploit the boundaries of coating technology and provide solutions for even the most challenging of surface treatment tasks.
