Seals are designed to prevent undesirable mass transfer within technical products. Because they are relatively inexpensive components, they are not usually given high priority in design. This is why seals often cause problems in development projects, because each application has its own requirements for a sealing element, which designers must be aware of.<\/p>

In this article, we take a look at three typical problems<\/strong> that can arise due to negligent handling of seals in the development of machines and devices. We will also tell you how you can effectively avoid the difficulties described.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Problem 1: The installation space is unsuitable for the intended seal<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Whether (and for how long) a seal can perform the task assigned to it depends not least on its installation environment<\/strong>. Even for simple O\u2011rings suitable grooves or recesses, for example, must be planned in the design into which the seal can be fitted. The requirements for sophisticated elements such as rotary or hydraulic seals are more complex and call for specific design expertise.<\/p>

If the intended installation space for a seal is insufficient, this can cause problems.<\/strong> Typically, existing design drawings need to be adjusted late in the product development process (PEP), requiring additional development loops. To avoid this, some companies opt for highly complex sealing elements that have yet to be designed for the project \u2014 including costly tooling concepts. In the worst case, a seal is installed defectively so that it fails sooner or later in use. At one manufacturer of electronic devices, for example, an improperly installed seal caused the electronics to come into contact with dust and fail completely after a short time.<\/p>

Manufacturing companies that want to avoid delays, consequential costs and loss of reputation must already sufficiently consider the requirements of each sealing component (installation space, functional requirements, etc.) in their design drawings. However, this does not mean that designers should design their machines around the seal. A simple catalog of measures<\/strong> listing all relevant requirements and processes can often nip the difficulties described above in the bud.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Problem 2: The seal material does not match the general conditions of the machine<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Seals are also sometimes subject to strict legal requirements<\/strong> and quality standards. Design teams must be aware of these requirements at the beginning of the development project in order to be able to design a seal correctly. Otherwise, this also leads to expensive delays and additional development loops.<\/p>

One example of this is the UL94 fire classification. This is used when a plastic article is exposed to a certain fire risk and must therefore be flame-resistant. In some cases, companies forget that this property must affect the entire product, not just individual components. They may use a UL94-rated plastic for the enclosure, but not for the seal. As a result, the overall product is not sufficiently flame resistant, which can affect further certifications.<\/p>

Such problems are not uncommon in the development of sealing components. They can be circumvented with conscientious material selection<\/a>. In doing so, companies must analyze in advance all relevant framework conditions that are of importance for the seal. In addition to legal requirements, these include:<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
