EMI interference is uncontained electrical noise that is circulated over a wide range of frequencies that originally exists at a base frequency and then eventually produces multiple harmonics. Problems with electromagnetic interference can be minimized by ensuring that all electronic equipment is operated with a good electrical ground system. In addition, cords and cables connecting the peripherals in an electronic or computer system should, if possible, be shielded to keep unwanted RF energy from entering or leaving. Since most rotating machinery generates a significant amount of electrical noise it is important that highly sensitive devices and components be shielded from EMI interference.
Fabri-Tech is a leading manufacturer of EMI gaskets for small electronics and other applications. Our EMI shielding gaskets will help protect your devices from electromagnetic interference (EMI) and protect users from any potentially harmful emissions your devices may generate.

EMI can cause many significant problems for all types of electronic equipment. Even the newest and most advanced models are susceptible to the effects of EMI. At Fabri-Tech, we provide custom EMI gasket options to help small electronics manufacturers block this interference. For cell phones, medical devices, A/V components, or any products of similar function or purpose that could potentially suffer the ill effects of electromagnetic interference, our EMI gaskets are a made-to-order solution. Some of the additional benefits of EMI gaskets and RFI gaskets include:
• Device sensitivity protection through increased immunity of susceptible circuits.
• Circuit isolation through shielding, grounding, and filtering
• Suppression interference that corresponds to immunity requirements.
RFI and EMI interference share a range of similarities and differences. However, EMI is a frequency of electrical noise, while RFI is a specific subset of electrical noise on the EMI spectrum. Radiofrequency interference can also be described as a disturbance that affects an electrical circuit due to either electromagnetic conduction or electromagnetic radiation emitted from an external source. The disturbance may interrupt, obstruct, degrade, or limit the effective performance of the circuit. In addition, the negative consequences that result from electromagnetic interference can include temporary disturbances, data losses, system failure, and loss of life.
EMI shielding gaskets are mechanical devices that provide protection for electronics from electromagnetic interference. Conventionally, EMI shielding gaskets have been manufactured from metal sheets and formed into shapes that fit electronic housings or enclosures. In addition, aluminum, copper, and steel are strong and rigid, but thin metal sheets can deform under certain sealing pressures.
Furthermore, Fabri-Tech can cut copper foil, aluminum foil, or other materials to the exact configurations of your product or device, and these cut-out pieces can then be applied where needed to block EMI. The same processes and materials can be used to shield end users from emissions that your devices may generate.
As premiere EMI gasket manufacturers Fabri-Tech can create the perfect custom EMI gaskets for your products. We have many different methods and materials at our disposal with which to fabricate EMI gaskets. Our EMI gaskets are manufactured from a variety of materials, including:
• Molded elastomers
• Stamped elastomers
• Extruded elastomers
• Die-cut elastomers
• Oriented wire
• Wire mesh
• And other materials
In addition, EMI gaskets can be die cut, water jet cut, or compression molded from electrically conductive silicone rubber compounds with age and weather resistance. They can also be manufactured from conductive fluorosilicone rubber for additional chemical resistance.
Each of the above-mentioned shielding materials provides their own unique advantages. Moreover, our particle-filled silicone elastomers provide premium electromagnetic interference shielding, while combining the electrical properties of metals with the material properties of silicone rubber. This makes them exceptionally durable and highly resistant to all forms of RFI and EMI interference. EMI gaskets and RFI gaskets can prevent all types of Electromagnetic interference.
At Fabri-Tech we are a high-end EMI gasket manufacturers that create custom EMI gaskets to meet our customers’ needs, but that doesn’t mean you’ll pay the high prices usually related to “custom” work. Our experienced employees have the experience and the technological resources to produce custom parts and components at economical prices. Fabri-Tech will work with you to design the ideal custom EMI gasket(s) for your needs.
