III. Production Process and Inspection Specifications (Refer to GB 6 and 7)

1. Core Production Process

The mainstream production process of the 48mm smart cap is compression molding, which complies with the national standard requirement of "injection molding, hot pressing, or other processes". The specific production process is as follows:

Raw Material Preparation: Fully stir and mix food-grade HDPE or PP particles with color masterbatch to ensure compliance with national hygiene standards;

Quantitative Extrusion: Extrude the mixed raw materials into the compression mold according to the set dosage;

Mold Clamping and Compression: After the mold is closed, compress and shape the raw materials to ensure the 48mm smart cap has a full appearance and no defects;

Ring Cutting Process: Use special equipment to process the connecting bridges between the tamper-evident band and the cap body, and precisely control the breaking torque;

Cooling and Setting: Rapidly cool the formed cap through a closed-loop water cooling system to ensure the dimensional accuracy meets the tolerance requirements;

Quality Inspection: Adopt 7 lenses for 360° comprehensive inspection to eliminate products with unqualified appearance and dimensions;

Packaging and Warehousing: Seal and package qualified products with food-grade packaging bags to avoid contamination during transportation and storage.

2. Strict Inspection Rules

Batch Division: Products produced continuously on the same production line with the same raw materials are classified as one batch, and the quantity of each batch of 48mm smart caps shall not exceed 1.2 million pieces;

Inspection Classification:

Factory Inspection: Mandatory inspection items include appearance (GB 5.1), dimensions (GB 5.2), and printing pattern adhesion performance (GB 5.3);

Type Inspection: All items need to be fully inspected (i.e., all requirements in Chapter 5 of the national standard). Type inspection shall be initiated when new product finalization, material or process change, resumption of production after more than 6 months of suspension, receipt of quality problem feedback, or request from users or regulatory authorities occurs;

Sampling and Judgment: Implemented in accordance with the double sampling plan of GB/T2828.1. The Acceptable Quality Level (AQL) for appearance, dimensions, sealing performance and other items of the 48mm smart cap strictly follows the provisions of Table 6 of the national standard; if any item in the hygienic performance test is unqualified, the entire batch of products shall be judged as unqualified.

IV. Marking, Packaging, Transportation and Storage (Refer to GB 9)

1. Product Marking

The packaging box of the 48mm smart cap shall comply with the requirements of GB/T191 "Packaging - Pictorial Marking for Handling of Goods". The box shall clearly mark the product name, specification (48mm), quantity, trademark, full name and address of the manufacturer, external dimensions, transportation and storage precautions, and be accompanied by a qualification mark. Clear marking can allow consumers to quickly understand product information and facilitate subsequent transportation and management.

2. Packaging Requirements

The packaging process shall be carried out in a clean and dust-free environment. First, seal the 48mm smart cap with packaging bags that meet food hygiene standards, and then put them into the packaging box; if there are special requirements, the packaging method can also be determined through negotiation between supply and demand parties.

3. Transportation Specifications

The vehicles or tools responsible for transportation shall be kept clean and dry. The stacking weight of boxed products shall not exceed the bearing capacity of the outer packaging. During transportation, avoid direct sunlight, rain, pollution, and severe impact to ensure the products are intact.

4. Storage Conditions

The 48mm smart cap shall be stored in a clean, dry, and well-ventilated warehouse, with the ambient temperature controlled between 18℃~38℃;

If the storage ambient temperature is lower than 18℃, the product shall be transferred to an environment above 18℃ for 24 hours before use;

During storage, keep away from heat sources and pollution sources, and it is strictly prohibited to mix with toxic, harmful, and strong-smelling items. Moisture-proof measures shall be taken in the warehouse to avoid product quality being affected by environmental humidity;

Storage Period: From the date of production, the storage period of the product shall not exceed 12 months.

V. Purchase and Use Tips

1. Key Purchase Points

Confirm Compliance: When purchasing, check whether the product complies with GB/T17876-2010 and whether the merchant can provide the corresponding hygienic performance test report (GB/T5009.60), which is an important guarantee for qualified products;

Inspect Appearance Quality: High-quality 48mm smart caps are fully formed, with a smooth surface, no shrinkage, bubbles, burrs, black spots, or other defects, and the connecting bridges of the tamper-evident band are intact without breaking marks;

Verify Dimensional Adaptability: Confirm that the product caliber is 48mm, and the inner plug and thread can be precisely adapted to the bottleneck of your own barreled water to avoid unusable situations;

Pay Attention to Material Safety: Prefer products made of HDPE or PP materials. The packaging shall clearly mark "food-grade" and "BPA-free" to ensure drinking water safety;

Test Sealing Performance: You can simply check whether the top-piercing sheet is intact without damage and whether the inner plug is deformed. If necessary, perform an upside-down test to confirm no leakage before purchasing.

2. Practical Use Suggestions

Operate gently during installation, handle with care, and avoid rough handling that may damage the 48mm smart cap or tamper-evident band, affecting the sealing performance;

Before use, ensure that the column of the water dispenser's smart seat is clean and dry to prevent pollutants from entering the water source and affecting drinking water hygiene;

After opening the barreled water, it is best to drink it within 7 days to maximize the freshness of the water quality and avoid bacterial growth;

When storing barreled water, avoid direct sunlight and high-temperature environments. High temperature will accelerate plastic aging, which may affect the hygienic performance of the product and shorten its service life.

In today's era where drinking water safety and convenience are emphasized, the 48mm smart cap has become the preferred accessory for large-caliber barreled water due to its excellent technical standards, reliable sealing performance, thoughtful anti-theft design, and wide adaptability. From production to inspection, from transportation to use, the entire process of the 48mm smart cap strictly follows national standard requirements, not only ensuring drinking water safety but also bringing a convenient user experience. Whether it is daily household drinking water, office area water supply, or precise needs in special fields, it can be perfectly adapted to protect people's healthy drinking water. As its core category, the 48mm tamper-evident top-piercing cap, with its prominent anti-theft and anti-counterfeiting advantages, has become an important support for the standardized development of the barreled water industry.
