Frequently Asked Questions about Automatic O-Ring Assembly

Does OHRMANN provide complete assembly automation for my products?

Yes – we also offer complete assembly lines, if the seal assembly is part of the process. Additionally, our integration modules can be incorporated into existing assembly automation solutions.

Ohrmann covers solutions for a wide range of seals – where are the limits?

Alongside the large number of seal types we work with, there are some clear boundaries. For example, flat seals. Additionally, there are certain types of seals where fully automated assembly is less feasible, such as mechanical seals. As for seal sizes, we have experience with seals ranging from 0.7 x 0.4 mm to 660 x 15 mm. Tasks outside these size ranges must be evaluated on a case-by-case basis.

I have a very unique case – do you offer custom solutions?

Yes! We see ourselves as custom machine builders and love exploring new paths. Thanks to our experience, we often find simple solutions for complex cases. Challenge us with your special case!

Can I integrate Ohrmann solutions into my assembly line?

Yes! We have integration modules especially designed for this use case. Many of our customers are automation companies that offer industrial automation to their customers. Ohrmann integration modules are a perfect fit in these cases. The complete development and ramp-up of such solutions is usually very time and money consuming. Why not use an economical solution from the world leaders in O-ring assembly right away?
