EMI RFI Shielding Solutions

Electromagnetic interference (EMI) is unwanted noise or interference caused by electromagnetic radiation from external sources, such as mobile phones, power lines, or nearby electronics. Radio frequency interference (RFI) is a specific type of EMI within the radio frequency spectrum (typically 10 kHz to 100 GHz). Both can significantly impact the performance of sensitive electronic equipment.

EMI/RFI shielding refers to techniques and materials used to block or reduce this interference. Shielding is often achieved using conductive or magnetic materials that absorb or reflect electromagnetic waves, preventing them from reaching vulnerable components.

The Role of Metal Fabrication in Shielding

Metal components play a crucial role in effective EMI/RFI shielding. Materials like aluminum, copper, nickel, and stainless steel offer excellent conductivity and magnetic permeability, making them ideal for creating barriers against electromagnetic interference.

TMN Metal Parts Fabrications excels in the production of custom metal shielding solutions, including:

• Shielding enclosures

• Gaskets and seals

• Shielded housings

• Shield clips and spring fingers

• Cable shielding solutions

• PCB shielding cans and covers

Each component is engineered to fit your specific design requirements, ensuring optimal protection and seamless integration into your product.

Our Capabilities

At TMN Metal Parts Fabrications, we combine advanced manufacturing techniques with skilled craftsmanship to deliver high-performance EMI/RFI shielding products. Our core capabilities include:

1. Precision Metal Stamping

We use high-speed stamping presses to produce intricate shielding components with tight tolerances. From simple shields to complex multi-part assemblies, our stamping processes ensure consistent quality and cost-efficiency for both low and high-volume production.

2. CNC Machining

For parts requiring detailed features or low-run customizations, our CNC machining services provide unmatched precision and flexibility. This is especially valuable for prototypes or specialized shielding enclosures.

3. Deep Drawing and Forming

We manufacture deep-drawn metal parts that offer structural strength and enhanced shielding for demanding applications. This technique is ideal for enclosures and housings that must withstand environmental stress while providing effective EMI/RFI protection.

4. Laser Cutting and Welding

Our state-of-the-art laser cutting equipment allows for fast, accurate cutting of complex shapes in a wide range of materials. Laser welding further ensures strong, clean joints without compromising the shielding integrity.

5. Surface Treatments and Plating

To maximize shielding effectiveness and corrosion resistance, we offer a variety of finishes and coatings, including:

• Nickel plating

• Tin plating

• Conductive coatings

• Passivation

• Anodizing

Each surface treatment is selected based on the material and intended application, balancing conductivity with durability.

Custom Shielding Solutions

At TMN, we understand that one size does not fit all. That’s why we specialize in custom EMI/RFI shielding solutions tailored to your unique specifications. Our team works closely with your engineers to develop prototypes, refine designs, and produce high-quality components that meet all electrical, mechanical, and environmental requirements.

Key Customization Parameters:

• Material selection based on frequency range and environmental conditions

• Dimensions and thicknesses to match specific device layouts
