Electro-magnetic shielding of plastics

The electronics market has become very competitive today, and electronics companies are looking to simplify and streamline their product manufacturing processes. Metal equipment is definitely much more costly and provide much less flexibility in designing compared to plastic products, which is why electronics manufacturing companies are actively substituting metal with high-quality plastic.

What is electromagnetic shielding of plastics?
Electromagnetic pulses affect the function of electronic products. Medical equipment as well as electronics that are used in daily life such as mobile phones are susceptible to electromagnetic pulses that are emitted by other electronic products. To prevent equipment from damage and malfunctions it is necessary that electromagnetic shielding is done.

The process of shielding reduces EMI by reflecting or absorbing craze before they come close to electronic circuit boards and cause any damage at all. If shielding is done correctly, it can protect electronic systems from external radiation by breaking the path of electromagnetic waves. It also protects other external equipment from potential damage caused by other products emitting electromagnetic pulses. Though a lot of factors affect how little magnetic pulses work on electronics, the distance between source and the shield is also quite important.

It is important to understand that electromagnetic pulses may come from within the equipment itself, or they can originate outside. A proper shielding process will eliminate all potential risks of damage.

Masterbatches manufacturers in India add to the typical shielding process of using carbon fibre, stainless steel five or nickel coatings with their own products. These compounds can also incorporate flame retardant additives and wear additives, colourants as well as other reinforcements as required by the manufacturer.
