Laboratory & Feeding Tests

Extensive know-how in handling critical seals

Knowledge and experience of the feeding and assembly behaviour of seals are indispensable for the planning of assembly processes to ensure a smooth series start-up and to maintain permanently high machine availability. OHRMANN is the specialised technology leader in the field of seal feeding and assembly.

OHRMANN has extensive know-how in dealing with challenging assembly conditions and critical seals – an aspect that is often not sufficiently taken into account in assembly planning. In particular, very small O-rings with an inner diameter from 0.5 millimetres, but also very flexible rings with low cord thickness, certain base materials with mineral additives or silicone content as well as some coatings are considered critical and require special consideration.

OHRMANN feeder testing

While many suppliers of assembly automation see O-ring assembly as one process among many, OHRMANN deliberately uses a different approach. Even before a quotation is prepared, the OHRMANN feeder test is carried out for critical seals with sample parts, which documents important information for planning the assembly process.

Prevention of static charge in the feeding process

We pay special attention to the reduction of static charge and adhesion in the feeding process. Factors that favour occurrences of this kind are already eliminated during the planning process. As a result, many seals that used to regularly cause major problems in series production are now capable of being assembled in a process-safe manner. Thereby plant availability is significantly increased. One more reason to pay due attention to the C-part O-ring as early as the planning stage.

Performance tests

For critical seals and tasks, we carry out endurance tests before delivery or integration. In this way, we ensure that the cycle time required for the respective task is reliably fulfilled in the long term.
