Inside YuQi Industry's 20,000m² production plant: High-frequency ultrasonic welding technology, N35/N52 rare-earth magnet placement, and non-toxic food-grade ABS resin formulation.
Rather than relying on chemical glues that degrade over time, our high-speed automated ultrasonic welders melt plastic seams at the molecular level. This creates a hermetically sealed double-casing wall that withstands over 100+ Joules of impact resistance during lab drop testing.
We utilize Grade N35 to N52 Neodymium Iron Boron (NdFeB) magnets, nickel-copper-nickel plated for anti-corrosion longevity. Magnet strength is precisely calculated to provide effortless 3D construction stability while adhering strictly to international magnetic flux safety thresholds.
Our raw materials consist exclusively of non-recycled, high-clarity virgin ABS plastic. Free from BPA, phthalates, and heavy metals, our plastic maintains ultra-high transparency, scratch resistance, and vivid color vibrancy even under intense ultraviolet light exposure.
Mitigating compliance risk for global importers. Every batch produced by our wholesale factories is systematically tested and accompanied by valid laboratory certificates for seamless custom clearance.
Fully compliant with ASTM F963-23 (Standard Consumer Safety Specification for Toy Safety), CPSIA (Consumer Product Safety Improvement Act), Children's Product Certificate (CPC), and California Proposition 65 heavy metal limits.

Factory-direct Montessori blocks engineered by specialized manufacturers like YuQi Industry incorporate high-grade N35/N52 Neodymium magnets, food-grade virgin ABS resin, and double-welded ultrasonic seams. Unlike low-cost generic toys that use glue or cheap recycled plastic, our blocks undergo strict drop testing, torque tests, and colorfastness calibrations to ensure multi-year durability in demanding educational settings.
Safety is our primary engineering metric. We utilize high-frequency ultrasonic welding which fuses the plastic outer shell into a single solid piece at the atomic level. Additionally, internal retention ribs hold each magnet in an isolated internal chamber. Every batch undergoes 100+ Joule impact drop tests and 50N tension tests to guarantee zero magnet detachment, fully complying with ASTM F963-23 and EN71 safety standards.
For standard catalog inventory, our MOQs start as low as 50–100 sets. For custom Pantone color matching (such as our popular Macaron or Pastel palettes) and custom-printed retail packaging, the typical MOQ ranges from 500 to 1,000 sets per item. We offer flexible tiered pricing to accommodate growing brand owners and established international distributors alike.
