Production Line Configuration and Process Flow

The complete aluminum cap production line is seamlessly linked according to the cap manufacturing process sequence, covering the following core units:

Automatic Feeding System:

Precisely feeding aluminum coil into the stamping station with a feeding accuracy of ±0.15mm

Deep Throat Press:

Special deep throat punching press with , suitable for wide aluminum sheet feeding and multi-cavity die installation. Press force ranges from 80 to 300 tons.

Screen rings machine:

This machine is used to screen the cover and the edge material (ring) of the cover

Vibratory bowl or centrifugal cap orienting machine, automatically removing deformed or defective caps to ensure uniformity for the next process.

Conveyor and Cap Elevator:

Modular plastic belt or food-grade stainless steel conveyor, combined with a cap elevator to automatically lift caps to the knurling machine infeed, reducing manual handling.

Knurling/Thread Rolling Machine:

Driven knurling and thread rolling machine, embossing anti-slip patterns or threads on the cap sidewall, and imprinting brand logos on the top. Knurling depth and pitch are adjustable.

Automatic Gasket-inserting Machine:

• True Turnkey Project: All equipment is uniformly designed and manufactured by us, ensuring matching cycle rates and unified interfaces, eliminating compatibility issues from multiple suppliers.

• Extremely High Production Efficiency: The line is designed for a maximum speed of 300-400 caps per minute, with a stable actual output of 240-300 caps per minute, requiring only 1-2 operators for 24-hour continuous production.

• Superior Forming Precision: Utilizing YASKAWA servo drives and MITSUBISHI PLC control, cap dimensional tolerance is controlled within ±0.05mm, with precise thread matching and excellent sealing performance.

• Quick Changeover: Dies and fixtures adopt quick-change structures, combined with a recipe management system. Product changeovers typically complete within 30 minutes by simply recalling parameters.

• Low Operating Cost: The entire line uses low-energy servo motors and an automatic scrap recovery system. Combined with reduced labor and improved yield, the per-cap manufacturing cost is significantly lowered.

This aluminum cap line can produce:

• Aluminum ROPP caps for premium liquor bottles such as Baijiu, whisky, and brandy.

• Aluminum screw caps for red wine, olive oil, and mineral water bottles.

• Long skirt aluminum caps for special bottle shapes or cosmetic packaging.

• Aluminum tear-off lids, aluminum cap rings, and more.

We provide full services from reverse engineering of cap samples to complete line layout design. As a manufacturer with a 15,000㎡ self-owned factory and ISO 9001 & CE certifications, we produce the presses, feeders, dies, and automated downstream equipment in-house, with core machining facilities including large gantry CNC centers, CNC lathes, and wire EDM machines. This ensures controlled delivery times and quality for the entire line. Our aluminum cap production lines have been exported to Europe, the Americas, the Middle East, and Southeast Asia, serving multiple cap suppliers for well-known distilleries and brands.

We provide a 12-month warranty for the entire aluminum cap production line, along with detailed installation videos, operation manuals, and electrical schematics. We offer 24/7 online technical support and can dispatch senior engineers for on-site installation, commissioning, and production training, ensuring your operation team masters the entire line in the shortest possible time.
