As the world continues to move toward an ever-increasing reliance on electronics for a variety of uses, the question then turns to the protection of these electronic devices. Interference from radio frequencies and/or electromagnetic energy can be damaging to electronics and render them inoperable. In answer to this critical issue, there has been a great deal of research conducted on shielding and ways to eliminate radio frequency interference (RFI) and electromagnetic interference (EMI).

Methods of Protecting Electronics

There are three primary methods of preventing interference from radio frequencies and electromagnetic energy. The first involves a reduction of cables and wires so that no excess is used. A second method requires the installation of additional parts, such as inductors, circuit breakers or capacitors, in an effort to provide a filter system. Providing some form of enclosure for the electronic device is the final method of protecting these valuable parts. For many of today’s applications, enclosures provide better protection at a more value-conscious price point.

Plastic Enclosures Offer Superior Protection

Unlike enclosures made of other materials, such as metal or aluminum, plastic enclosures provide a material that is easy to work with in terms of RFI/EMI shielding. In most cases, plastic enclosures that are designed to offer such protection are sprayed with a lacquer with an acrylic base that is combined with copper or nickel. This coating prevents the electronic device within the enclosure from being damaged by radiation.

Importance of Using Plastic Enclosures with RFI/EMI Shielding

Frequency disturbances that one device can emit could damage another electronic device. Using plastic enclosures with RFI/EMI shielding provides a simple and effective method of ensuring that these frequency disturbances are not an issue. Because RFI and EMI can cause significant interference in devices — such as the suppression of the signals that a device generates internally, internally-generated emissions that can interfere with normal equipment operations or ambient external interference with other equipment operations — providing a method of shielding is imperative for the successful operation of many of today’s crucial industries.

Industries Helped by RFI/EMI Shielding

One of the most important industries in the world today — the telecomm industry — relies heavily on preventing the effects of RFI and EMI. A signal’s reception can be hampered other signals that are too similar in frequency. Using RFI/EMI shielding can prevent interference from those frequencies that are not correct. Within the medical industry, the Food and Drug Administration (FDA) has set strict standards that medical providers must comply with. Medical equipment must not be affected by those electronic devices that are found throughout the facility, such as cell phones, tablets and other electronic devices. RFI/EMI shielding ensures compliance with these regulations. Within the board room, protecting audio/visual equipment from interference from nearby electronic devices with the use of RFI/EMI shielding increases productivity while protecting valuable equipment.

SIMCO specializes in offering enclosures to meet a variety of needs, including plastic enclosures with RFI/EMI shielding. The coating they use, SprayLac, is the leader in the industry and offers superior results for SIMCO‘s customers. Contact them at 800.780.9090 for more information.

RFI / EMI Shielding and Its Importance

April 4th, 2015

What is RFI/EMI?



This acronym means Radio Frequency/Electromagnetic Interference. This is a kind of interruption that has an effect on an electrical circuit that is caused by electromagnetic energy from an outside source.  When such interruption occurs, it will have a damaging effect on the electronic device affected. And since there is an increase of usage of electronic devices, there is a higher chance that an electronic interference may happen.  For this reason, there have been a lot of research and initiatives done in order to prevent this to ensue.

What are the different ways to prevent RFI/EMI?

There are several techniques to prevent RFI/EMI.  The first way is to use cables or wires as minimal as possible. This just simply means that when electronic devices are connected via cables or wires, it should be measured well so that no extra cable loops out.  When cables and wires are measured well, it has minimal chance to experience electromagnetic interference. Meanwhile if cables and wires are left looping, it can cause a lot of interferences.

The second way is to install a filter system on the electronic device. This just simply means that the electrical source and electrical load to and from the device should be carefully thought of. In doing this, capacitors and inductors or even circuit breakers must be installed to control the flow of electricity which protects the electronic device.

The third and most important way is to protect the electronic device with an enclosure that is RFI/EMI safe.  There are many kinds of enclosures that are proven RFI/EMI safe. There are aluminium, metal, and plastic enclosures available to all consumers around the world. The best and cheapest kind of enclosure to use on electrical device is plastic enclosure.  There are now plenty of plastic enclosures available in that provide electromagnetic interference shielding or EMI shielding.

What is RFI/EMI shielding?




RFI/EMI shielding is a way of protecting electrical devices that are installed inside plastic enclosures to ensure minimal or no electromagnetic interference.

Plastic enclosures that have RFI/EMI shielding are usually sprayed with an acrylic based lacquer combined with nickel or copper which prevent the housed electronic device from damages due to radiation.

Which company produces the best plastic enclosure with EMI shielding?

Top of the line plastic enclosures with RFI/EMI shielding are made available by Standard Injection Molding Company or Simco.  Simco uses the best and up-to-date spray coating to prevent RFI/EMI.

This coating is called the Electordag 550 Coating.

This most recent kind of coating has the best attenuation rate and has the highest guaranteed protection from radiation and emission.


Why is it important to use plastic enclosures with RFI/EMI shielding?

Using RFI/EMI shielding to protect electrical devices ensures no frequency disturbances from one device to another. For telecommunications companies, they need to protect their telecom devices from RFI/EMI so that no other radio frequencies may affect or intersect from the frequency that they use. A concrete example is when you turn on an old television set and you use a two-way radio nearby. Somehow the television will be interfered by the frequency used by the two-way radio. The television may broadcast the conversation transpiring from the two-way radio.

Another setting that really needs RFI/EMI shielding is the airport.  The constant communication transpiring among different airplanes and the tower must never be interrupted by any other radio frequency.  If there is no EMI/RFI shielding, disasters may happen. This is the reason why RFI/EMI shielding is very crucial.

What is Simco’s thrust when it comes to RFI/EMI shielding?

Since RFI/EMI shielding can save lives and make our everyday lives safer and better, Simco wants to make sure that the quality they offer is incomparable from any other companies.  In order for them to live by those values, Simco complies with standards that can assure top quality to all its clients.  Simco’s plastic enclosures go through testing at Underwriters Laboratories or UL.  This is a highly credible consultation and certification company located at Illinois. Simco is proud to state that all of its plastic enclosures are UL certified which means that all of its plastic enclosures have passed safety and quality tests.

In Summary

RFI/EMI shielding is essential to ensure no radio frequency leakage or infiltration between devices. Whether it is a small or big electronic device, it should still be shielded from RFI/EMI.

Now that we have discussed in detail what RFI/EMI is and how it is shielded, you can now understand the importance of using enclosures that have RFI/EMI shielding. Hence, should you need to enclose your electronic device and shield your other devices from radiation or emission; you should invest in good quality enclosures from Simco. All of its plastic enclosures are UL certified and can be RFI/EMI shielded.  You can check all their products at
