Engineered with high-grade N35 Neodymium magnets, food-grade ABS resin, and double-riveted ultrasonic welding for absolute safety and durability.
Navigating the international STEM toy market requires strict adherence to safety standards, structural durability, and supply chain scalability. Yongkang YuQi Industry and Trade Co., Ltd. bridges technical execution with global commercial compliance.
The primary concern for global buyers—including major retail chains in North America and Europe—is magnet displacement, which poses severe safety risks. Traditional magnetic bricks rely solely on glue or single ultrasonic seals. YuQi solves this via 360-degree double-riveted internal structural ribbing combined with ultrasonic seam fusion. Every batch undergoes 15kg tensile pull tests and high-impact drop verification.
Distributors require unique colorways, proprietary shapes, and custom branding to differentiate in competitive markets. Our in-house tooling plant enables quick prototype turnarounds in under 7 days. From specialized Macaron aesthetic series to custom translucent architectural tiles, our factory accommodates custom mold development with minimal tooling amortization fees.

Headquartered in Yongkang, Zhejiang—China’s epicenter of industrial hardware and high-precision plastic molding—YuQi operates an automated manufacturing infrastructure designed for scale, consistency, and rapid global fulfillment.
We exclusively procure prime-grade ABS plastic polymers directly from ISO-verified global petrochemical suppliers. Chemical purity is verified via batch spectroscopy to confirm complete freedom from heavy metals, phthalates, and bisphenol A (BPA).
Our 20,000 square meter plant incorporates 60+ fully automated robotic injection molding workstations. Robots precisely place individual Neodymium magnet cylinders into plastic housings, eliminating human placement error and optimizing cycle times.
Quality control is embedded at every phase: raw material inline inspection, automated optical visual check for surface clarity, 100% magnetic polarity alignment verification, and post-welding torque-drop stress testing.
Different commercial channels demand targeted product specifications. YuQi provides bespoke solutions crafted for educational institutions, mass retailers, and e-commerce brand builders.
Designed for kindergarten and primary school environments. Features reinforced 1.42-inch large-format magnetic cubes and tiles with curved safety corners, packed in stackable, heavy-duty storage bins accompanied by STEM curriculum playbooks.
Turnkey OEM solutions for global consumer brands. Custom shelf-ready retail packaging, FSC-certified color gift boxes, barcode integration, anti-counterfeiting holographic seals, and localized multi-lingual instruction inserts.
Optimized drop-test approved mail-order packaging designed to reduce dimensional shipping weights. Polybagged set configurations with predefined ASIN barcodes and fulfillment compliance for Amazon, Walmart, and Shopify merchants.
YuQi’s R&D team continuously advances magnetic toy architecture. Our forward-looking engineering roadmap outlines upcoming breakthroughs in smart connectivity, sustainable polymers, and spatial learning integration.
Implementation of free-floating cylindrical encapsulated N35 magnets within internal channels. Magnets automatically rotate 360 degrees upon proximity, ensuring instant connection regardless of polarity orientation, eliminating frustration for young builders.
Developing safe low-voltage conductive magnetic contact points embedded inside transparent tiles. Children can build 3D architectural castles that complete low-voltage LED circuits, powering light modules and miniature sound bricks without exposed wiring.
Transitioning target product lines toward 100% bio-based corn-derived polymers and Post-Consumer Recycled (PCR) ABS. This initiative helps global retail partners fulfill stringent European Scope 3 carbon emission requirements and circular economy goals.
Exporting to over 50 countries requires thorough understanding of regional product safety mandates. YuQi products carry full documentation tested by third-party laboratories (SGS, TUV, Intertek).
Fully compliant with United States mandatory safety standards, physical torque tests, small parts hazard tests, and lead content limits.
Certified for European Union distribution. Tested for mechanical safety, flammability, and migration of 19 toxic heavy elements.
Factory-wide Quality Management System and Environmental Management System certification for standardized batch production.
Children's Product Certificates issued for fast customs clearance across North America, China, and Gulf Cooperation Council countries.

For standard factory-ready packaging, our MOQ starts as low as 500 sets. For custom private-label branding, specialized colorways, or custom box packaging, our standard MOQ is 1,000 sets per item code. In-house mold modifications can be evaluated on a project basis.
We utilize a double-layer structural defense mechanism: First, individual magnets are secured inside internal structural plastic slots with internal plastic pillars. Second, the outer ABS plastic shells undergo high-frequency ultrasonic welding that welds the plastic together on a molecular level. Every production lot undergoes drop testing from 1.5 meters onto concrete.
Standard catalog products ship within 7 to 14 days after deposit confirmation. Custom OEM private label production runs typically take 25 to 30 days. Express prototype samples with custom logo print can be delivered via air within 5 business days.
Yes, we collaborate directly with accredited laboratory testing agencies including SGS, TUV, and Intertek. We can assist in filing for brand-specific Children's Product Certificates (CPC) and EN71/ASTM lab test reports bearing your entity's commercial name.
Complete range of high-margin magnetic tiles, 3D cubes, and STEM building block sets ready for bulk order fulfillment.
