As a premier Chinese global beer container manufacturer, Shanghai Friend Metals integrates advanced metallurgy, precise mechanical forming, and zero-defect quality control to meet the rigorous physical demands of global filling lines.
Aluminum beverage container manufacturing relies on rigid metallurgical specifications to balance wall-thickness reduction against structural resistance. Modern standard, sleek, and slim can bodies utilize 3104-H19 aluminum alloy coil. This temper exhibits superior work-hardening capabilities during the Deep Drawing and Ironing (DWI) sequence, yielding axial crush strength exceeding 900 N even when wall gauge is thinned down to 0.095 mm.
For easy-open ends (SOT and RPT), shell stock is fabricated from 5182-H48 or 5182-H19 alloy, providing high tensile modulus required to resist internal carbonation pressure up to 6.2 bar (90 PSI) without dome reversal or buckle failure. Stay-on tabs leverage ductile 5052-H32 alloy to eliminate tab fracturing during high-speed opening.
Flavor preservation and corrosion prevention in beer and acidic RTD beverages demand strict barrier isolation. We apply next-generation BPA-Non-Intent (BPA-NI) acrylic and modified polyester internal lacquers via high-pressure electrostatic spray lances.
The film weight is continuously monitored between 35 mg/sq.in and 50 mg/sq.in depending on liquid aggressiveness (e.g., high IPA hop acids, dark stouts, or carbonated hard seltzers). Post-bake cross-linking checks are performed using enamel rater testing (<2.0 mA micro-porosity threshold) to guarantee zero metal pick-up, maintaining organoleptic purity over a 12-to-24 month shelf life.

Why top-tier global beverage brands partner with Chinese manufacturing hubs for primary metal packaging, raw coil sourcing, and automated high-speed logistics.
Direct integration with top-grade Chinese aluminum rolling mills allows raw coil allocation (3104, 5182, 5052, 8011) with precise gauge tolerances (±0.002 mm). Raw material price hedging mechanisms ensure stable long-term pricing for global enterprise contracts against London Metal Exchange (LME) volatility.
Our Shanghai manufacturing operations utilize automated multi-cavity conversion presses operating at up to 3,000 ends per minute. High-resolution optical vision systems inspect 100% of finished ends for score depth micro-cracks, tab alignment defects, and curl damage before automated vacuum sleeve packing.
Proximity to Shanghai Port facilitates rapid container loading and custom export handling. Advanced ocean palletization utilizes solid wooden or plastic top frames, kraft slip-sheets, and heavy-duty stretch-hood shrink wrapping to ensure zero pallet tilting or moisture intrusion during trans-oceanic voyages.
Meeting the strict quality assurance frameworks, traceability mandates, and international food contact regulations required by multinational breweries and global beverage conglomerates.
Every lot of aluminum beverage cans and easy-open ends undergoes stringent overall and specific migration testing. Our packaging materials strictly comply with:
To eliminate risk on automated high-speed filling lines running at 1,200+ cans per minute, enterprise procurement demands flawless structural consistency:
Understanding the shift toward sustainable circular packaging, craft beverage expansion, lightweighting innovations, and sleek format adoption.
Aluminum is a 100% infinitely recyclable material. Over 75% of all aluminum ever produced remains in active use today. Global brand owners are actively replacing single-use glass and PET with aluminum cans to fulfill ESG mandates. The inclusion of Post-Consumer Recycled (PCR) content in 3104 alloy sheet stock significantly reduces scope 3 carbon emissions.
Independent craft breweries worldwide are rapidly abandoning glass bottles in favor of 330ml, 355ml, and 473ml (16oz) aluminum cans. Cans provide 100% protection against UV light exposure (preventing "skunking"), offer superior thermal conductivity for quick chilling, and cut shipping freight weight by over 35%.
State-of-the-art wall-ironing dies allow container wall thickness to be re-engineered down to 0.092 mm while preserving axial load strength through engineered bottom dome geometries. Reducing material weight per thousand cans translates directly to lower freight costs and minimized environmental impact.
