We advise to always do a trial with the first design. An alternative in this case is a lip seal. the freedom of movement of the seal, deviate considerably and are larger than usual, an O-ring may not always be able to move with it.
If the tolerances in the construction, i.e. Whether an O-ring can be used depends on the dimensions. An O-ring that is pressed in well gives the best seal, but the strength and space required for this is not always there in the construction. The simplest and most effective seal is the O-ring, a seal with which NDS-Seals has a great deal of experience. In addition to choosing the right material, it is also important to choose the right shape of the seal. Furthermore, the use of certain colours in the seal can provide recognition to facilitate the assembly process. If, for example, parts need to be assembled automatically, the seal can be treated so that no more friction can occur. After all, correct assembly is essential for the customized seal to function optimally. The method of assembly is also taken into account. In that case, the investment is slightly higher, but you can save on maintenance because the seal does not need to be replaced as often. In some cases it may be more advantageous to choose a more expensive material that has a longer lifespan. DurabilityĪnother aspect that is taken into account in the choice of materials is durability.
If a seal must be very wear-resistant, polyurethane or natural rubber can be chosen, for example. In that case, EPDM or silicone can be chosen. In the construction of a coffee machine, for example, a seal must be resistant to hot water and suitable for foodstuffs. Is it about sealing air, water or oil, for example? On the basis of these data, a basic material is chosen. The design process of a seal generally begins by identifying three factors that the seal faces: The dimensions and corresponding tolerances form the starting point of the design process. NDS-Seals can still support you in these cases on the basis of the construction data. It may also be the case that the seal used does not function properly, for example if a standard seal has been used. However, it may be the case that your construction has already been designed, but afterwards it turns out that a seal still needs to be applied. This allows you to work cost-efficiently. If you pay immediate attention to the required seals during the design phase, NDS-Seals can advise you about the possibilities. We advise you to involve us in your design process at an early stage.
Customized sealing: get advice from the start In this article you can read how this process works. NDS-Seals has the knowledge and experience to bring the design of your construction to a successful conclusion with the right seal. The design process of a seal is a meticulous process in which various factors have to be taken into account. In this way we can ensure that the right seal is made to measure for you. Usually NDS-Seals is therefore directly involved in the design of new constructions. NDS-Seals supplies total solutions in the field of customized sealing in a wide variety of constructions.
