　　With strict source control over food-grade raw materials, the base adheres to the highest safety standards for children’s tableware. It exclusively selects high-purity food-grade tinplate, with all incoming raw materials attached with authoritative material test reports. Four strict pre-warehouse inspections including heavy metal screening, purity detection, corrosion resistance testing and non-toxic verification are implemented to eliminate inferior recycled plates and impure materials, fundamentally preventing heavy metal exceeding standards, material aging and harmful substance precipitation. All surface coatings and sealing accessories adopt food-grade eco-friendly materials, free of BPA, PVC, phthalates and other harmful additives. Complying with national GB4806 food contact standards and passing multiple authoritative international tests including FDA, LFGB and SGS certification, the products are safe for direct holding of hot and cold meals with high temperature resistance, corrosion resistance and no residual odor. Different from ordinary factories that mix general materials, the base implements an exclusive raw material management system for children’s tableware, completely isolating industrial packaging materials to fully protect children’s dining safety.

　　Adopting exclusive children-oriented refined craftsmanship, the base optimizes detailed safety performance to adapt to young students’ usage habits. Based on years of R&D and production experience in children’s tableware, it establishes exclusive safety process standards, different from adult tableware and ordinary tin boxes, to weaken the rigid defects of metal materials and strengthen safety protection details. The integral seamless stamping forming technology eliminates splicing gaps and welding spots to avoid dirt accumulation and bacterial growth, suitable for students’ repeated cleaning and daily use. All box openings, corners and handles undergo multiple fine grinding and rounded passivation treatments to remove burrs and sharp edges, preventing scratching and bruising and fitting children’s gripping posture. The eco-friendly flexible matte curing coating features strong adhesion, scratch resistance, fade resistance and fingerprint resistance, avoiding accidental ingestion caused by peeling paint during long-term use. Meanwhile, the sealing structure is optimized for bumpy campus commuting scenarios, with precise closing tolerance and high-elastic food-grade sealing parts to achieve effective leak-proof and fresh-keeping performance, adapting to schoolbag carrying, classroom storage and canteen dining scenarios.

　　The multi-layer full-process quality control system realizes zero-defect factory standards and stable batch quality. Strictly implementing the ISO9001 quality management system and SEDEX social responsibility system, the base builds a seven-level quality control mechanism covering raw material warehousing, procedural production, semi-finished processing, finished product shaping and outbound sampling inspection. A triple inspection system of self-inspection, cross re-inspection and final inspection is adopted for every working procedure. Special strict tests are customized for core children’s tableware indicators, including heavy metal dissolution detection, high-temperature weather resistance test, leak-proof sealing test, edge safety detection, coating wear resistance test, compression deformation resistance test and food contact safety test to eliminate potential safety hazards. Random full-item sampling is carried out for batch orders to strictly control color difference, dimensional error and process defects, ensuring highly unified batch quality without hidden dangers. All finished products undergo sterile cleaning and independent dust-proof packaging before delivery to eliminate factory pollution, fully meeting the strict quality requirements of large-scale campus procurement and brand bulk supply.

　　The large-scale flexible production capacity and efficient delivery system adapt to diverse order demands and ensure stable supply. With multiple synchronous automatic production lines and sufficient daily output, the production base flexibly undertakes large-scale campus procurement orders, regular brand bulk orders, cross-border export orders and small-batch customized sample orders without backlog or delivery delay.
