Market Applications for Shielding Tooling
Our custom shielding dies are designed to meet the strict isolation standards of modern high-frequency electronics:
Smart Mobility: Radar and LiDAR housing shields, GPS/GNSS receiver modules, and central infotainment processor enclosures.
Telecommunications: 5G base station transceiver covers, optical network router housings, and high-speed server blade shields.
Mobile Electronics: Smartphone mainboard shielding frames, wearable device battery covers, and tablet Wi-Fi/Bluetooth module cans.
Proprietary Engineering Pillars & Architectural Innovations
To prevent the manufacturing defects commonly associated with drawing thin-gauge reflective metals, our shield tooling incorporates several advanced design features:
Ultra-Flatness Pressure Management: Shielding cans must sit completely flush on a PCB to ensure effective soldering and prevent RF leakage. Our dies feature balanced, nitrogen-driven pressure pads that eliminate oil-canning and warping, keeping flatness tolerances tight across the entire part profile.
Precision Micro-Perforation Blocks: Many shielding covers require micro-ventilation holes for thermal management. We engineer high-density punch clusters that perforate arrays of ventilation holes cleanly without distorting the surrounding flat surfaces of the metal strip.
Engineered Pre-Score & Snap-Off Lines: For two-piece shielding designs (where a cover snaps onto a frame), the tool integrates micro-scoring stations. This creates crisp, repeatable dimples and detention detents, ensuring a perfect mechanical click-fit every time.
Zero-Scrape Forming Radius: Shielding parts are typically made from pre-plated tin or nickel silver, which can easily flake during tight bending. Our bending radii are mirror-polished and treated with slick vanadis coatings to prevent scratching or compromising the protective plating layer.
Operational Advantages on the Factory Floor
1. Zero Burr Edge Execution
Any tiny metal burr remaining on an EMI shield can break off during assembly and cause a catastrophic electrical short on the host PCB. Our tools utilize tight, modern wire-EDM clearances and premium tool steels to deliver completely clean, burr-free edges, making secondary tumbling or deburring completely unnecessary.
2. Optimized High-Speed Material Utilization
Because shielding covers are essentially hollow, box-like structures, standard strip layouts can generate substantial center scrap. Our design engineers specialize in nested, interlocking strip layouts and multi-row configurations. This significantly reduces your material scrap rate and directly lowers your cost per part.
3. Integrated SMT Tape & Reel Coordination
To prepare shields for high-speed robotic picking on PCB assembly lines, the stamped parts must exit the press organized and damage-free. Our dies are designed to interface seamlessly with down-line automated packing systems, placing completed shields directly into protective carrier tape pockets.
