X-Ray Foreign Object Detection Machine—The Ultimate Solution Beyond Traditional Needle Detectors
Industry development: Upgrade from "Metal" to "All Foreign Objects"
In the clothing, footwear, and home textile industries, contamination by metal foreign objects (such as broken needles, nails, and debris) during production has long been a serious quality and safety hazard.
Traditional "needle detectors" (which detect metal through magnetic fields) have been the industry standard for decades. However, as global supply chains become increasingly complex, consumer safety standards grow stricter, and brands pursue flawless product quality, needle detectors—limited to detecting ferromagnetic metals—have revealed their shortcomings. Non-ferrous metals (such as stainless steel, copper, aluminum), glass, ceramics, stones, rubber fragments, and other "invisible" contaminants are becoming new risks plaguing the industry.
To address this, we introduce the Garment-Specific X-Ray Foreign Object Detection Machine. This is not merely a technological upgrade from needle detectors but a revolution in quality management—from "metal detection" to comprehensive foreign object prevention and control.
Enable intuitive positioning of foreign object locations
Allows exclusion of zippers, buttons, underwires, and decorative components from detection, addressing the limitation of traditional needle detectors which cannot inspect products with such metal parts
Delivers more comprehensive coverage and improved detection precision

Revolutionary Expansion of Detection Range
Traditional Needle Detectors: Can reliably detect only iron-based (Fe) magnetic metals.
X-Ray Detection Machines: Based on differences in density and atomic weight, they can simultaneously and efficiently detect:
All metals: Iron, stainless steel, copper, aluminum, lead, etc.
Non-metallic minerals: Glass, ceramics, sand, stones, hard plastics.
High-density rubber/compounds: Certain sole fragments, hard impurities.
Product integrity: Can indirectly identify missing components (e.g., accessories, pads) or uneven filling.
Unmatched Reliability
Traditional needle detectors are easily affected by product moisture, salt content, placement, and environmental interference, leading to false alarms or missed detections.
X-ray technology offers strong penetration and intuitive imaging, unaffected by material, temperature, or humidity. It identifies foreign objects more stably and accurately, significantly reducing production efficiency losses and quality risks caused by misjudgments.
Visual Evidence and Process Optimization
Real-Time Imaging: When a foreign object is detected, the screen directly displays its precise location, size, and shape within the product, eliminating the need for manual repeated checks and enabling quick identification of the source of contamination.
Data Recording: Images and results of each inspected product can be saved, providing irrefutable electronic evidence for quality traceability and meeting the strict audit requirements of European and American brands.
Addressing Challenges of Modern Production Processes
Modern garments often incorporate metal accessories (zippers, buttons, decorative clasps), aluminum foil insulation layers, printing pastes containing trace metals, etc. Traditional needle detectors continuously alarm for such "acceptable metals," rendering the device unusable.
X-ray machines are equipped with advanced intelligent recognition software, allowing easy setup of "inspection zones" and "ignore zones." They scan only high-risk areas like fabric and filling cotton while automatically ignoring permitted accessories, achieving efficient and precise full inspection.
Typical Application Scenarios
High-End Brands and Export Manufacturers: Meet the "zero-tolerance" foreign object control regulations and customer standards in markets like Europe, America, and Japan.
Infant and Children's Clothing and Products: Categories with the highest safety requirements, where any hard foreign object risk must be eliminated.
Down/Fiber-Filled Products: High risk of contaminants like glass, metal, or hard plastics in fillings; X-ray is the only effective online detection method.
Underwear and Close-Fitting Garments: Soft fabrics with extremely high comfort requirements; even tiny foreign objects can lead to complaints.
Denim and Workwear: Multiple production processes and frequent use of metal tools increase contamination risks.
Fabric Roll and Cut Piece Inspection: 100% inspection of raw materials before cutting, blocking contamination at the source for the highest cost-effectiveness.
