custom emi shielding

Electromagnetic Interference (EMI) refers to the disruption of electronic circuits caused by electromagnetic radiation from nearby sources. This interference can be radiated through the air or conducted through wires and circuit boards. Without proper shielding, EMI can lead to:

• Data loss or corruption

• Signal degradation

• Malfunctioning devices

• Reduced performance or device failure

• Non-compliance with international regulations (e.g., FCC, CE)

With the rise of wireless communication and densely packed PCBs, EMI shielding has become a crucial part of electronic product design.

Why Choose Custom EMI Shielding?

Off-the-shelf EMI shielding components are not always the best fit—literally or functionally. Many devices have unique layouts, space constraints, or performance requirements that demand custom-designed shielding. TMN offers tailored solutions that integrate seamlessly into your design without compromising form, function, or manufacturability.

Our custom EMI shielding offers:

• Perfect fit for your specific layout and dimensions

• Material selection based on frequency, environment, and conductivity needs

• Custom openings, slots, or ventilation for heat dissipation

• Shielding cans, enclosures, covers, or gaskets designed for your product

We work hand-in-hand with your design team to create a shielding solution that supports performance, compliance, and cost-efficiency.

TMN’s Capabilities in Custom EMI Shielding

At TMN Metal Parts Fabrication, we combine engineering expertise with advanced manufacturing to produce high-performance custom shielding components tailored to your needs.

1. Wide Range of Shielding Components

• Metal shielding cans and covers

• Board-level shields

• Two-piece enclosures

• Custom-molded or stamped shields

• Clip-on and soldered shields

• Conductive gaskets and mesh screens

Every part is designed to block or redirect EMI effectively while fitting precisely into your product architecture.

2. Premium Materials

We offer a selection of high-performance shielding materials that ensure excellent conductivity, corrosion resistance, and formability:

• Nickel Silver

• Stainless Steel

• Copper

• Aluminum

• Brass

• Conductive foams and elastomers (for gasket applications)

Material selection is based on your device’s EMI frequency range, environmental exposure, thermal considerations, and assembly method.

3. Advanced Fabrication Techniques

Our facility uses precision metal stamping, laser cutting, CNC machining, and deep drawing to ensure accuracy and repeatability. This allows us to produce custom EMI shields with complex shapes, fine features, and tight tolerances.

We also offer value-added processes such as:

• Plating (tin, nickel, silver, etc.)

• Surface treatments

• Custom etching or marking

• Prototype tooling and short-run production

• Reel-to-reel and progressive die fabrication for high volumes
