Strict Parameters, Preferred Gift — Mini Car Gift Tin Box, with "standardized parameters, traceable quality and strong gift adaptability" as its core positioning, focuses on the core needs of gift scenarios, and specifies detailed core parameters in all dimensions such as size, material, process, safety and customization. It combines the cute appearance of mini cars with the exquisite texture of gifts. Relying on precise parameter control and standardized production, each tin box meets the gift-level quality standards, adapting to diverse gift scenarios such as holiday gifts, parent-child gifts and brand souvenirs, becoming a preferred mini car gift tin box with appearance, quality and practicality. We have been deeply engaged in the R&D and production of mini car gift tin boxes for many years, adhering to the core concept of "parameters determine quality, details show ingenuity", strictly controlling every parameter standard, refining parameter details, so that the parameters of each mini car gift tin box can accurately adapt to the needs of gift scenarios, build a solid quality foundation with standardized parameters, empower gift value with precise parameters, and show the sincerity and style of gift-giving.

　　Precise and Standardized Size Parameters, Adapting to Gift Scenarios, Balancing Appearance and Practicality. Based on the portability and display needs of gift giving, scientific and standardized size parameters are set, divided into two series: mini gift version and regular gift version. Each series of parameters has undergone repeated calculations, balancing the cute shape and practical storage, accurately adapting to different gift scenarios and gift-giving needs, no size deviation, ensuring the consistency of mass production. Mini Gift Version: The overall shape is a mini car, with a body length of 8-10cm, width of 4-5cm, height of 3-4cm, hexagonal base side length of 2.5-3cm, and weight controlled at 25-35g. It is small and exquisite, can be easily put into gift bags and hand-held boxes, adapting to the gift of small gifts and souvenirs, easy to carry and display; Regular Gift Version: Body length 11-13cm, width 5-6cm, height 4-5cm, hexagonal base side length 3-3.5cm, weight 40-50g, moderate capacity, can hold small jewelry, candies, beauty samples and other gifts, adapting to formal gift-giving, holiday gifts and other scenarios. Both versions adopt rounded corner design, with a corner radius of 0.5-0.8cm, no sharp protrusions, and coordinated size ratio, which not only meets the delicacy of gifts, but also takes into account the safety of use, adapting to gift-giving needs of different age groups.

　　Strictly Up-to-Standard Material Parameters, Gift-Level Quality, More Assured Safety. Strictly following the gift-level material standards and national safety standard for children's products (GB 6675-2014), the material parameters of each part are clarified. From the main body to the accessories, each material has undergone strict screening and testing to ensure safety, harmlessness and outstanding texture, adapting to the quality needs of gift giving. Main Material: Food-grade cold-rolled iron plate is selected, with thickness accurately controlled between 0.3-0.35mm, material purity ≥99.9%, no excessive heavy metals and no harmful residues. After double environmental protection pre-treatment of chrome-free passivation and high-temperature rust removal, the surface is smooth and delicate, no burrs and no odor, which can directly contact food, jewelry and other items; Surface Coating: Environmentally friendly soybean ink is used, with thickness 0.02-0.03mm, full color and strong adhesion, wear-resistant, not easy to fade and peel off, meeting the environmental protection gift standards, and maintaining an exquisite appearance after long-term storage; Internal Accessories: The buckles are made of high-strength ABS environmental protection material, with hardness ≥85D, tough and durable, not easy to break after repeated opening and closing; The sealing ring is made of food-grade silicone, with thickness 0.2-0.25mm, odorless and non-aging, with excellent sealing performance. All materials have passed SGS comprehensive testing, and all parameters meet the gift-level safety standards, balancing quality and safety.

　　Exquisite Process Parameters, Details Show Texture, Adapting to Gift Style. Standardized process parameters are formulated, with clear parameter specifications for each process. Relying on intelligent CNC equipment and a professional craftsman team, it ensures that the process accuracy meets the standard, so that each tin box has gift-level exquisite texture, and the details show ingenuity. Stamping Process: Stamping accuracy is controlled within ±0.02mm, ensuring that the car body shape is regular, lines are smooth, no skew, no deformation and no unevenness, and the car shape reduction rate is ≥98%; Welding Process: Seamless welding technology is adopted, the welding joint width is ≤0.1mm, flat and smooth, no welding beads and no gaps, improving the overall structural sturdiness, not easy to damage; Polishing Process: After 3 rounds of fine polishing, the surface roughness Ra ≤0.8μm, smooth and burr-free, warm hand feel, fitting the delicate needs of gifts; Printing Process: High-definition screen printing technology is adopted, with printing accuracy ≥300dpi, clear patterns and uniform colors, no blurring and no missing printing, adapting to the pattern and text printing needs of gift customization, making each tin box have both appearance and texture.

　　Safety and Customization Parameters Adaptation, Diversely Meeting Gift Needs. Based on the safety and personalized needs of gift scenarios, safety parameters and customization parameters are clarified, balancing safety and exclusivity, adapting to different gift-giving scenarios and customization needs. Safety Parameters: Formaldehyde emission ≤0.1mg/L, heavy metal content (lead, cadmium, etc.) ≤0.01mg/kg, no odor and no irritation, meeting the gift-level safety standards, adapting to gift-giving for different groups such as the elderly, children and friends; High Temperature Resistance Parameters: Can withstand a temperature range of -20℃ to 80℃, not easy to deform and fade, easy to store and transport, adapting to bulk gift stock-up; Customization Parameters: Supports pattern, text and logo customization, customization size error ≤±0.1mm, printing color deviation ≤△E2.0, customization area can cover the side and front of the car body, adapting to the customization needs of brand souvenirs, holiday gifts and other scenarios, short customization cycle, no additional price for bulk customization, balancing personalization and economy. All parameters support traceability query, and each batch of products is accompanied by a parameter test report, ensuring that the gift quality is guaranteed and gift-giving is more assured.
