Gasket Manufacturing Services

EMI Shield Seal Gasketing
Gasketing strips are available in various material combinations and sizes. The versatility of Abante's materials and sizes provides assurance of protection against temperature extremes as well as Electro Magnetic Interference and Radio Frequency Interference leakage. Materials conform with military specifications. The elastomers (Neoprene or Silicone) are available with or without an adhesive backing.

The gasketing strips are used in applications, such as electronic cabinets, to seal off stray EMI signals around the doors of the cabinet. The gasketing strips are also used extensively to shield electronic boxes of various sizes and shapes.

Adhesive backing on the elastomer is often preferred due to the ease of strip mounting. The knit wire mesh is available in various wire materials with Monel and Ferrous materials being the most popular. Double shield strip materials are available for added shielding effectiveness. Contact us to determine which material would best suit your requirements.

Gasketing strips with adhesive backing are convenient during the engineering or prototype stages of projects. In production stages, it is more convenient and economical to have Abante manufacture the complete gasket with the necessary mounting holes, compression stops and other special mechanical consideration incorporated. Each gasket would be complete and ready for installation, thereby increasing reliability and reducing labor costs during assembly of the end product.

EMI / RFI Gaskets for Connectors
Abante offers connector gaskets in order to reduce the ingress or egress of EMI/RFI interference from connectors to an enclosure bulkhead. Supported connector types include AN Series, Bendix, and RF-Type.

Various combinations of gasket dimensions and connector shell sizes are available. The choice of elastomer and metal used for grounding is dependent upon the environment in which the equipment will be operating.

EMI / RFI Rigid Frame Gaskets
The composition of Rigid Mounting Frame EMI/RFI Gaskets includes an aluminum extrusion with a specially designed jaw. When closed, the jaw crimps the fin of the knit wire EMI gasket to form a rigid construction with the EMI gasket held firmly in place.

When fabricated into a frame with mitered and heliarc-welded corners, these gasket assemblies can be installed with flat-head screws. This design makes retro-fitting in the field a relatively easy task and, at the same time, provides a positive stop for controlled compression of the EMI Gasket.

Rigid frame gasket is recommended for larger cabinet doors or access panels doors that are frequently opened. For applications requiring a moisture seal, an elastomer strip can be bonded to the edge of the extrusion opposite the gasket.

An added barrier to EMI/RFI interference can be achieved by utilizing a double-shielded construction. Double-shield gasketing is recommended for larger doors for which controlling the mating surface joint unevenness can be difficult and expensive. Another advantage of the rigid frame approach, with its load bearing support, is in cases when shock and vibration are encountered.

EMI Wire Mesh Gasketing
Knitted wire mesh gasketing is available in various cross sections to satisfy the many different requirements encountered in shielding applications. The choice between rectangular, round, round-with-fin, or double-round-with-fin depends on the enclosure or equipment to be shielded. Each strip has the same resiliency, created by the knit construction, but reacts differently dependent on material and shape. Of the most common materials used, monel has the best spring factors while silver-plated brass has the highest conductivity.

Rectangular or round shapes are recommended for groove mounting, while single-round-with-fin or double-round-with-fin is recommended for flat surfaces. Surface conditions must be clean, and free from contamination such as paint or oil, for good conductivity. There should be an even distribution of pressure along the length of the gasket.

Die-Cut Gaskets
Abante offers a variety of die-cut gaskets that meet or exceed the most demanding standards. Configurations of any shape or size are available with the optional application of pressure-sensitive adhesive materials. Our gaskets and seals are used by a variety of electronic, telecommunication, aerospace, and medical firms.
