In the design and manufacturing of modern electronic products, Electromagnetic Compatibility (EMC) and precision structural connections are two core factors determining product quality and reliability. Whether in smartphones, communication base stations, automotive electronics, or medical devices, internal circuits face increasingly complex electromagnetic challenges—such as high-frequency signal crosstalk, external electromagnetic interference (EMI), and unstable ground loops. Even minor oversights can lead to degraded performance or total functional failure.
With nearly 20 years of deep expertise in the EMI sector, Qiyiguo Technology is a professional manufacturer and supplier of EMI shielding components and precision metal parts in China. We also offer a wide range of Pogo Pins. Backed by ISO9001 and IATF16949 dual-system certifications, we deliver high-quality, highly reliable products and services across industries including consumer electronics, communication equipment, automotive electronics, medical devices, and industrial control.
Qiyiguo Technology’s EMI shielding components and precision metal parts comprise two core product lines, addressing the full spectrum of needs from electromagnetic protection to precision connectivity:
Utilizing high-precision molds and advanced stamping processes, we provide a variety of precision metal components, including conductive contact springs, SMT grounding contacts, copper pillars, EMI conductive springs, metal clips, and terminals.
These products are widely used for PCB grounding, circuit connections, structural fastening, and signal shielding. Their high precision, consistency, and superior material properties ensure the electrical performance and structural reliability of electronic products.
These electromagnetic shielding structural components are stamped from high-quality metal materials. By forming enclosed or semi-enclosed shielding cavities, they effectively isolate sensitive circuits from interference sources, blocking both radiated and conducted electromagnetic waves.
Our product range covers applications such as shielding cans for smartphone motherboards, RF modules, automotive electronics, wearable devices, laptops, power modules, industrial control equipment, medical devices, and communication equipment. Offering shielding effectiveness exceeding 60dB, our products help you successfully obtain major EMC certifications like FCC and CE.
Our two major product lines complement each other, offering a comprehensive solution covering electromagnetic shielding, grounding/bonding, structural connection, and signal transmission. This enables superior EMC design and more efficient supply chain management during the product development phase.
We hold both ISO9001 and IATF16949 (automotive industry) quality management system certifications. Our production processes strictly adhere to the five core quality tools—APQP, PPAP, FMEA, SPC, and MSA. Our products meet general industry standards for consumer electronics, telecommunications, and medical devices, while also passing the automotive industry's most rigorous audits. We possess the capability for mass delivery of automotive-grade products, meeting the qualification requirements of OEMs and Tier 1 suppliers.
With EMI shielding components and precision metal parts integrated into a single product ecosystem, you can consolidate your purchasing with one supplier. This reduces communication costs, lowers supply chain risks, and improves delivery efficiency.
We maintain an in-house mold design and manufacturing team, supporting the entire process from product concept to mass production. Our mold precision reaches ±0.01mm, ensuring high dimensional consistency across products.
We work with a wide range of metals—including copper alloys, stainless steel, tinplate, nickel silver, carbon steel, and aluminum alloys—and can recommend the optimal material based on your specific requirements for conductivity, corrosion resistance, weldability, and cost.
Every stage is strictly controlled, from incoming raw material inspection and in-process checks to final product inspection and pre-shipment testing. We utilize professional testing equipment—such as 2D measuring instruments, network analyzers, force testers, contact resistance testers, and salt spray chambers—to ensure consistent and reliable product quality.
We support small-batch prototyping with turnaround times as fast as three days. Flexible delivery schedules for mass orders help shorten your product development cycle and accelerate time-to-market.
We offer customization based on your drawings or samples. Our engineering team can engage early in the design phase to help optimize product structure, enhance manufacturability, and reduce overall costs.
Our EMI shielding components and precision metal parts are widely used in the following sectors:
Consumer Electronics: Smartphones, tablets, laptops, TWS earbuds, smart wearable devices
Communication Equipment: 5G base stations, Wi-Fi/Bluetooth modules, optical modules, routers, switches
Automotive Electronics: Vehicle ECUs, ADAS (Advanced Driver Assistance Systems), BMS (Battery Management Systems), in-vehicle infotainment systems
Medical Devices: Patient monitors, ultrasound equipment, portable diagnostic devices, medical probes
Industrial Control: PLC modules, servo drives, variable frequency drives (VFDs), test fixtures
New Energy: Charging piles, energy storage systems, inverters, power modules
Qiyiguo Technology holds both ISO9001 Quality Management System certification and IATF16949 Automotive Quality Management System certification. ISO9001 ensures our production processes meet internationally recognized quality management standards, while IATF16949 signifies that our manufacturing capabilities have passed the most rigorous system audits in the global automotive industry.
Yes. Both EMI shielding components and precision metal parts are part of our product portfolio, allowing you to source everything from a single supplier. This not only streamlines communication and reduces supply chain management costs but also ensures consistency in material selection, surface treatment processes, and quality standards across both product categories, thereby enhancing the overall performance of the finished product.
Qiyiguo Technology accepts custom orders based on provided drawings or samples, supporting formats such as CAD, STEP, and IGS for 3D models and 2D engineering drawings. If you only have a preliminary concept or specific functional requirements, our engineering team can assist with structural design, material selection, and process optimization, helping to control costs and improve manufacturability right from the design stage.
The prototyping lead time is typically 3–7 working days, depending on product specifications and tooling requirements. Mass production lead times depend on order volume but are generally completed within 7–15 working days. Specific delivery dates will be confirmed with you upon order placement.
There is no MOQ requirement for the prototyping stage, facilitating validation during product development. For mass production, the MOQ can be negotiated based on product specifications and manufacturing complexity; please contact us for a detailed quote.
We offer comprehensive technical support covering the entire process—from product design optimization, material selection advice, and EMC solution consulting to mold development, sample validation, and mass production. Please feel free to consult our engineering team if you encounter technical challenges related to EMC or precision interconnects during product development.
If you are looking for a reliable supplier of EMI shielding components and precision metal parts, please feel free to contact us. Whether you need product inquiries, technical discussions, drawing evaluations, or mass production quotes, our professional team is ready to provide efficient, expert service.
