Custom vs Off the Shelf

Some companies like Stimpson offer "off the shelf" ferrules or grommets as part of their product line and through their catalog. In these cases, companies like Stimpson have invested in the tooling required to manufacture these catalog items and can offer them in lower volumes at reasonable prices.

Trans-Matic does not have a ferrule product line, but instead works with customers on custom ferrules or eyelets for volumes over 500,000 per year with dedicated customer tooling.

About Ferrules & Eyelets

Within the manufacturing world, the terms ferrule and eyelet are often used interchangeably. Both ferrule and eyelet describe a metal cap that is used to shield, cover, connect, bind, or convey. In the most common example, the metal cylinder used to hold the eraser onto a pencil is a ferrule, as is the metal cap at the end of a garden hose.

Ferrules can be made of almost any kind of metal. Some of the most common metals used in ferrule manufacture include stainless steel, low carbon steel, brass, copper, bronze, and aluminum. The choice of metal depends on the application of the ferrule: fluid conveyance ferrules often use copper, brass, or stainless steel, while ferrules used as a heat sink are often created from aluminum.

Some of the uses for ferrules and eyelets include:

  • Shield: ferrules can shield parts or cables from electromagnetic pulses, environmental damage, the elements, damage protection, thermal shielding including absorption or dissipation from a heat sink.
  • Cover: ferrules can act as a covering to add wear resistance to a part, as damage protection and as a part of packaging.
  • Connector: ferrules can be used to connect wires, structural devices, and systems.
  • Bind: ferrules can be used to bind parts together, including bundles of wires or binding the cloth threads of a mop to the base of the handle.
  • Conveyance: ferrules can be used as a conveyance for fluids (hydraulic ferrule) like oil and water, or as a conveyance for gasses (pneumatic ferrule) like air.

Within a deep drawn metal stamping context ferrules and eyelets can be used in several different ways. They can make connections in order to convey gasoline or other fuel from a fuel line to a fuel rail to a combustion cylinder through an injector cup. Ferrules can be used to protect wire harnesses used in automotive oxygen sensors in the form of a heat or wear resistance shield covering the harness. Ferrules are also used as EMP (electromagnetic pulse) shields for data transferring devices like Ethernet cables. Ferrules are used for automotive cable connectors, and literally hundreds of other uses.

Ferrules are an incredibly versatile and diverse component that is common throughout manufactured items. Some parts can use off the shelf components, while many others require custom manufactured ferrules. For high volume, custom ferrule and eyelet manufacturing, contact Trans-Matic.
