Quality Assurance
Effective Date: 2026
Quality is our top priority. We are committed to providing premium, precise, and durable 3D metal puzzle models for every customer. Every product undergoes strict standardized production and inspection procedures to ensure reliable quality and perfect assembly experience.
1. Premium Material Selection
All our metal puzzle kits are made of high-quality stainless steel and brass materials. The raw materials are rigorously screened for sturdiness, corrosion resistance and long-term durability. We adopt eco-friendly and sturdy metal materials to avoid deformation, rust and fragility, ensuring finished models can be permanently collected and displayed.
2. Precision Manufacturing Standards
Equipped with industrial laser cutting and precision electroplating production lines, all metal parts are precisely cut within 0.1mm tolerance. Each component features smooth, burr-free edges and accurate sizing, realizing tight glue-free assembly. Strict production standards effectively avoid loose fitting, part deviation and structural defects.
3. Strict Multi-Stage Inspection
We implement full-process quality control from raw material screening, part production, surface treatment to final packaging. Our professional QC team conducts random and full inspections to check part completeness, cutting accuracy, surface finish and structural stability. Defective products will be eliminated before delivery to guarantee every qualified kit reaches customers.
4. Exquisite Surface Craftsmanship
All products adopt professional electroplating and polishing technology, delivering smooth texture, uniform color and excellent oxidation resistance. The premium metallic finish effectively prevents fading and scratches, maintaining a brand-new appearance for long-term display and collection.
5. Quality After-Sales Support
We provide reliable after-sales quality service. If customers receive missing parts, damaged components or quality defective products, we offer free replacement parts and professional solving solutions. We always stand behind our product quality and strive to bring every customer a reassuring and satisfying shopping experience.
