Form in Place Conductive Gaskets:
Our automated Form-In-Place gasketing process applies programmed conductive elastomer gasket beads on to metal or plastic substrates. These highly reliable seals can be applied to flanges as narrow as .035″. FIP process compensates for uneven surfaces and affords more real estate in your overall packaging design. The bead exhibits very good adhesion to plated metals, shielded plastics, stainless steel and vacuum metalized surfaces. Attenuation exceeds 75 dB between 200Mhz and 10Ghz.
Form in Place Environmental Gaskets:
Our automated Form-In-Place gasketing process also applies environmental non conductive elastomer beads to metal and plastic substrates. These form in place gaskets provide reliable environmental seals and have excellent adhesion properties. Beads are dispensed with robotic accuracy providing a highly conformable gasket that can accommodate various height requirements.
Engineering Notes: We have the capability to do all in house tooling, locating fixtures and programming. Compression range is 10% to 50%, with 30% ideal depending on material. Bead diameters and placements are verified with vision measuring equipment. We offer a wide range of materials but will also work with any customer specified materials.
FIP UV Curable Gasket Video
Central Coating is now offering the latest generation in Form-in-Place (FIP) Gasket Application using UV curing dispensing technology. This process and material is used for sealing Plastic, Glass, Metal and Plated surfaces and enclosures. The dispensed gaskets acts as a moisture seal preventing air, dust, liquids, gaseous substances and dirt from penetrating the enclosure. The gaskets are cured in-line, increasing production speeds and turn-around times. These curable materials contain no nonreactive solvents and are silicone free! These materials conform to intricate channels and recesses.

FIP Gasketing Utilizing Trishield® Technology
Central Coating is now offering the latest generation in FIP Gasketing using the Trishield® dispensing technology.
The benefits of Trishield® include lower compression force, shorter production time and lower cost The newest material is called Trishield Soft®, which is a modified version of traditional Trishield® gasket. It is co-dispensed with both conductive and non-conductive material. The technique, however, remains unchanged as a precise string of electrically-conductive silicon rubber is dispensed onto a carrier and is then formed into the characteristic shape.
Central Coating employs a unique technology to apply the material in a triangular and wave shaped gasket. Materials applied include silicone nickel, nickel graphite and soft nickel graphite. Trishield®Soft is available in gasket heights of 1.2 – 2.5 mm, and in a range of metal fillers including Ni/C, Ag/Ni or Ni/Al, depending on customer requirements. Application of these materials results in up to 70% lower compression force and a low compression set.
Advantages of TriShield includes:
- Excellent shielding properties – Up to 110 dB
- Saves space on PCB by reducing the number of screws
- Reduced over-all cost – Less machining, fewer screws,
- thinner and more flexible covers
