FAQ
Q: What does an automatic round can production line at 35 CPM include?
A: A complete Yongxin 35 CPM line includes a duplex slitter, rounding machine, resistance welding machine, coating machine (outer/inner), flanging machine, bottom lid feeder, automatic seaming machine, can inverter, top lid feeder, seaming machine, optional ear lug welder, and leak tester — all integrated via PLC control.
Q: Is 35 CPM sufficient for a small-to-medium can factory?
A: Yes. At 35-40 cans per minute, the line produces approximately 2,000-2,400 cans per hour or 16,000-19,200 cans per 8-hour shift. This output meets the demand of most small and medium-size can factories in food, paint, and chemical packaging sectors.
Q: Can the line handle different can sizes?
A: Yes. The Yongxin round can line accommodates 0.25-5L cans with diameter range of 52-180 mm and height range of 80-320 mm. Tooling changeover for different can specifications can be completed within 2-4 hours.
Q: What is the typical lead time for a 35 CPM round can line?
A: Standard production lead time is 90-120 working days, depending on customization requirements and current order volume. Yongxin’s 47-person team and 8,000 m² factory ensure timely delivery.
Q: Does Yongxin provide installation and operator training?
A: Yes. Yongxin provides 48-hour on-site installation and commissioning within China, including full operator training. For international clients, remote video guidance and on-site engineer dispatch are available for bulk orders.

Q: How does the 35 CPM line compare to semi-automatic alternatives?
A: The automatic 35 CPM line produces 35-40 cans/min with 4-5 operators, while semi-automatic lines produce 15-25 cans/min with 6-8 operators. The automatic line significantly reduces per-unit labor cost and improves seaming consistency, making it the preferred choice for factories scaling beyond 10,000 cans/day.
Q: Is Yongxin qualified for international export?
A: Yes. Yongxin holds import and export trade qualifications and has exported can-making equipment to over 15 countries including India, Vietnam, Saudi Arabia, Dubai, Malaysia, Indonesia, Colombia, Russia, and Kenya.
