Source Control, Ingenious Craftsmanship — Die Cut Tin Plate Box, with "source traceability, precision die cutting, high-quality tin" as the core, strictly controls from three aspects: raw material source, process source and quality source. Relying on precision die cutting technology, it creates a die cut tin box with both texture and practicality, accurately adapting to diverse scenarios such as storage, decoration and gift giving, and becoming a preferred product that highlights ingenuity and quality in the field of tin storage. We adhere to the concept of "source determines quality, and exquisite craftsmanship creates good products". From tin material procurement to die cutting production, every source link is strictly controlled to eliminate defects, so that each die cut tin box carries the ingenuity from the source, balancing appearance, durability and practicality, and adapting to the needs of home, supermarket, gift and other scenarios.

　　Raw Material Source: Select High-Quality Materials, Lay a Solid Foundation for Quality. High-purity food-grade tin plate is selected from the source, with a tin content of ≥99.5% and a material density of 7.3g/cm³. Inferior raw materials are eliminated from the source to ensure the product is safe and durable. The tin plate is all from qualified source suppliers, and each batch of raw materials is strictly tested. The heavy metal content and harmful substance residues all meet the national food contact safety standards, with lead content ≤0.001mg/kg and no harmful volatile substances, protecting use safety from the source. The raw materials are preprocessed at the source to remove impurities and polish smoothly, improving the toughness and wear resistance of the tin plate, laying a solid foundation for the subsequent die cutting process, ensuring that the finished product is not easy to deform or break, with a service life of ≥36 months.

　　Process Source: Precision Die Cutting, Restore Detailed Texture. The die cutting process is independently developed and optimized from the source, using high-precision die cutting equipment with a die cutting accuracy of ≤0.01mm, accurately controlling every cut and every line, ensuring that the tin box has a regular shape, smooth corners, no burrs and no deviations. From die cutting mold design, debugging to mass production, the whole process is controlled from the source. The mold is made of wear-resistant steel, with no loss after die cutting ≥10000 times, ensuring that each product has a unified shape and consistent details. The die-cut tin box undergoes multiple processes such as polishing, grinding and welding at the source, with seamless connection and close fit, which not only ensures structural stability, but also improves the overall texture, making the precision of the die cutting process reflected from the source.

　　Quality Source: Strict Control, Eliminate Defect Hidden Dangers. Establish a full-process source quality control system. From raw material warehousing, process production to finished product delivery, each link is inspected by special personnel to prevent unqualified products from entering the market. The finished product inspection focuses on core indicators such as die cutting accuracy, sealing performance and load-bearing performance, ensuring that the tin box has a flat cut, smooth opening and closing, and tight sealing, and each product meets the quality standards. Defects are avoided from the source, making the die cut tin box not only have practical functions, but also carry the ingenuity from the source, adapting to diverse scenarios such as storage, decoration and gifts, and showing quality strength.
