Empty Three-Piece Tin Cans Supplier for Milk & Beverage Packaging

High-precision empty three-piece tinplate cans designed for automated beverage filling lines. We are a professional OEM/ODM manufacturer dedicated to supplying high-precision empty tinplate cans to the global beverage and dairy industries. Our open-top three-piece steel cans are ready for immediate filling and are perfectly compatible with high-speed automated washing, filling, and seaming systems. Understanding that even minute dimensional variations matter, we precision-engineer our cans to ensure zero-downtime operation on your filling lines.

Key Technical Highlights:

Strict Flanging and Seaming Tolerances—The top flanges of our open-top cans are manufactured to rigorous micron-level tolerances. This ensures that upon arrival at your filling facility, the automatic seamer's chuck can form a perfect double seam, completely eliminating the risk of micro-leaks after filling.

High-Speed ​​Depalletizer Compatibility—The can bottoms and body beads (reinforcing ribs) are dynamically balanced in design. They glide smoothly on magnetic or vacuum depalletizers and conveyor tracks, effectively preventing tipping or jamming even during high-speed filling operations exceeding 500 cans per minute.

FAQ

Q: Do your empty beverage cans come with the easy-open end (EOE)—either bottom or top—pre-seamed?

A: As a flexible manufacturer, we offer two options based on your equipment setup: we can pre-seam the EOE onto the bottom of the can, leaving the top open for your filling process; or we can ship the can bodies and ends separately, allowing your seamer to seal the cans after filling.

Q: How do you ensure the internal food-grade coating isn't scratched during the can manufacturing process?

A: We utilize advanced non-magnetic nylon guide rails and air-cushion conveying systems throughout our production line. This ensures that the delicate white or clear internal coating does not rub against rough metal surfaces during forming, thereby maintaining the integrity of the protective layer.

Q: Can your factory manufacture empty tinplate cans with customized heights to meet specific capacity requirements?

A: Yes. While maintaining standard diameters (such as the 52mm or 65mm sizes commonly used in beverage filling lines), we can flexibly adjust our slitting and welding equipment to customize the can body height, thereby meeting your requirements for precise filling capacities such as 180ml, 240ml, or 330ml.
