OA fully automatic machine

Let us work for you! OA fully automatic machines for seal assembly.

Our OA machines assemble O-rings using the patented joining sleeve assembly process with minimum ring elongation. A vision sensor checks the assembly result. Only 100% correctly assembled parts end up in the IO box. That is process reliability in large-scale production.
