All raw materials (quartz sand, soda ash, limestone, etc.) are inspected for composition and particle size to ensure consistent glass formula. The first article produced after mold setup is strictly checked for initial dimensions, surface quality, and mouth finish to confirm process stability.
During high-temperature forming, real-time monitoring ensures uniform molten glass flow and proper mold filling. Post-annealing internal stress detection is conducted to eliminate hidden cracks, ensuring the mechanical strength and safety of the bottles.
Bottles undergo manual light table inspection to identify invisible flaws such as bubbles, stones, cracks, and black spots. Automated AI vision systems are used for mass production to achieve high-precision detection of surface and internal defects.
Professional measuring tools (caliper, micrometer, gauge) are used to strictly verify key dimensions including bottle height, caliber, mouth diameter, and wall thickness. This ensures perfect compatibility with caps, pumps, and filling equipment.
Leak-proof Test: Simulate actual transportation and use conditions to verify the sealing performance of the bottle cap system.
Pressure & Impact Test: Conduct internal pressure resistance and thermal shock tests to ensure the bottle can withstand internal pressure and temperature changes.
Perform repeated screw and cap tightening tests to confirm the matching degree between the bottle mouth and various caps. Ensure no liquid leakage occurs during transportation and use.
Random sampling is carried out from finished product batches to conduct a comprehensive re-inspection of appearance, dimensions, and performance. Only products that pass all inspections are marked and packaged for shipment.
Inspect carton packaging integrity, inner lining protection, and palletizing stability. Verify shipping marks, barcodes, and quality certificates to ensure accurate information and safe transportation.
We implement a full-process quality control system from raw materials to finished products, committed to providing customers with 100% qualified, safe, and reliable food-grade glass bottle packaging.
