TNA\u2019s Smart Factory, Qinhuangdao<\/h2>\n\n\n\n

TNA\u2019s Smart Factory<\/a> in Qinhuangdao spans 27,000 m\u00b2, with an annual output of 50 million units. It is a nationally recognized \u201cLittle Giant\u201d enterprise and a certified green factory, accredited under three major management systems and holding LPCB and UKCA international certifications.<\/p>\n\n\n\n

Powered by ARM9 processors, real-time Linux systems, and 5G-enabled remote connectivity, every product that leaves here stands the test of time and rigorous scrutiny<\/p>\n\n\n\n

Injection Molding<\/h2>\n\n\n\n

The facility operates 41 Chen Hsong injection molding machines, covering five clamping force specifications: 120T, 160T, 260T, 320T, and 800T. By using top-tier equipment, consistent product quality is ensured.<\/p>\n\n\n\n

Plastic pellets are melted and injected into molds under controlled conditions. As molds open and close, robotic arms retrieve each component with precision. From raw pellets to finished housings, the entire process is completed within a single injection molding cycle.<\/p>\n\n\n\n

Surface Mount Technology (SMT)<\/h2>\n\n\n\n
\"\"<\/figure>\n\n\n\n

Seven SMT lines operate with high precision and stability. From solder paste printing and 3D SPI inspection to high-speed placement of micro-components, each board passes through reflow soldering and then undergoes AOI scanning, where every solder joint is inspected with micron-level accuracy.<\/p>\n\n\n\n

Every PCBA undergoes 100% optical inspection, ensuring consistent quality. Micron-level precision is where millimeter-level safety begins.<\/p>\n\n\n\n

Magnetic Levitation Production Line<\/h2>\n\n\n\n
\"\"<\/figure>\n\n\n\n

China\u2019s first fire detector production line to adopt magnetic levitation technology<\/h3>\n\n\n\n

Four custom-built insertion machines operate at 2,000 cycles per hour, performing precise bending and insertion of through-hole components. After wave soldering, a UV coating system applies a conformal coating layer, providing protection against moisture, mold, and salt spray. A dual-spindle milling cutter rotates at high speed to produce smooth, low-stress edges on the panels.<\/p>\n\n\n\n

Subsequently, magnetic levitation pallets carry the semi-finished products, gliding along the track without contact and eliminating the vibration and friction associated with traditional conveying systems.<\/p>\n\n\n\n

Automated assembly, electrical calibration, and laser marking are performed in sequence. Inside the automated aerosol detection chamber, an optical densitometer calibrates smoke concentration, ensuring an environmentally friendly and highly accurate measurement process<\/p>\n\n\n\n

The final packaging uses PE heat-shrink film, forming a tight protective layer over the product. The entire production line operates at a rate of 2,000 units per hour, achieving an Overall Equipment Effectiveness (OEE) of 85%, exceeding the industry average by 10 percentage points and reaching world-class standards.<\/p>\n\n\n\n
