Custom Seals from Gallagher Fluid Seals

While you could buy seals made with the size and materials of industry standards, sometimes the performance may not be up-to-snuff. Whether you have a static or a dynamic application, each one has its own unique traits and characteristics. Rather than finding a product that "fills the needs" of your specific application, wouldn't it be more prudent to create the perfect solution?

Using custom-engineered seals from GFS, specific to your application, can help solve that.

Size

No matter the size, Gallagher can assist. Whether less than 1 millimeter or dozens of inches of diameter, our expert engineering team can help design the solution for the exact dimensions you need. Our ability to have the exact sizes and designs fabricated with our global partnerships can help you get it for the right price, too.

Different Manufacturing Processes

Depending on the application need, the type of manufacturing process can have major advantages over another type.

  • Injection molding is generally considered the most cost-effective molding process, suitable for high-volume productions of small products that require tight tolerances and little finishing. The process involves feeding material into a press, which is warmed and injected into a mold. The process very precise, due to the control the manufacturer can have over the pressure, temperature, and speed at which the material enters the mold.
  • Compression molding is suited for low-to-medium production volumes and larger parts which do not require the tightest tolerances or perfect finishes. Rubber is pre-heated and then inserted into a mold by a press. It is held there until cured. Benefits include: lower tooling costs, faster production, and higher durometer materials.
  • Transfer molding uses a press and mold much like compression molding. But unlike compression molding, transfer molding uses a piston to force a material through a passage into the mold cavity. This method can produce very complex components (ofen larger products) with tight tolerances at a high production rate. Production cost for transfer molding tends to be higher due to these benefits.

Material

One of the most important choices for sealing applications is material. There are a wide variety of materials to choose from, each with their own unique properties. If you haven’t determined the right material for your application, your application performance could be suffering.
