Introduction
For manufacturers seeking a reliable square can making machine from China, Jiujiang Yongxin Can Equipment Co., Ltd. (九江市永信制罐设备有限公司) delivers 21 years of specialized expertise in tinplate square can production, with 86 patents and automatic lines reaching 30-35 CPM output. Yongxin’s square can making line covers 0.5-5L rectangular containers for paint, chemical, tea, and food applications — equipped with PLC-controlled servo systems, 4-roller and 6-roller precision seaming, and complete after-sales support for international buyers across Southeast Asia, the Middle East, and Africa.
Industry & Market Context
Global demand for square tin can packaging continues to expand. The specialty tin cans market was valued at USD 683 million in 2026 and is projected to reach USD 979.4 million by 2036, growing at a CAGR of 4.1% (source: Future Market Insights). In Asia, particularly China, the square tin box market is outpacing global averages at 8.1% growth, driven by food, cosmetics, and gift packaging demand (source: China Packaging Federation / Mintel, 2025). Meanwhile, the global can making machines market is estimated at USD 1,023.38 million in 2026 and expected to reach USD 1,756.57 million by 2035, experiencing a CAGR of 6.3% (source: 360 Research Reports, 2026-04).
A square can making machine addresses a distinct manufacturing challenge: producing rectangular tinplate containers that require precise corner forming, consistent body welding, and hermetic seaming — processes more complex than round can production. International buyers increasingly source can manufacturing equipment from China for its integrated tinplate supply chain, competitive pricing (25-40% lower landed cost vs. Western OEMs), and proven export qualifications.

Products & Solutions: Square Can Making Machine Lineup
Yongxin’s square can making machine portfolio spans fully automatic production lines and specialized seaming equipment for 0.5-5L rectangular tinplate containers.
Small Square Can Making Line 30-35 CPM
The small square can making line produces 0.5-5L square cans at 30-35 CPM, suitable for paint tins, chemical containers, tea cans, and food packaging. The complete line includes:
| Parameter | Specification |
|---|---|
| Can Capacity Range | 0.5-5L |
| Production Speed | 30-35 CPM |
| Applicable Material Thickness | 0.2-0.4mm tinplate |
| Can Height Range | ≤400mm |
| Motor Power | ~14 kW |
| Line Dimensions (L×W×H) | ~15,000 × 2,000 × 2,500 mm |
| Net Weight | ~15,000 kg |
| Control System | PLC + servo motor |
Key processes in the line include: sheet shearing → body rounding → side seam welding → flanging → body beading → seaming (bottom & top). The PLC-controlled servo system ensures consistent can body dimensions and repeatable seaming quality across production runs.
4 Roller Square Can Automatic Seamer
For buyers requiring standalone or supplementary seaming capability, Yongxin offers a 4-roller square can automatic seamer designed for precise double-seam formation on rectangular containers:
| Parameter | Specification |
|---|---|
| Applicable Can Size | 0.5-5L square can |
| Seaming Rollers | 4 rollers (2 first-operation + 2 second-operation) |
| Production Speed | 20-35 CPM |
| Seaming Type | 5-layer double seam |
| Control | Schneider PLC + servo feed |
| Lid Feed | Automatic suction-cup system |
| Height Adjustment | Automatic servo-driven |
The 4-roller configuration provides balanced seaming pressure distribution across the square can’s four corners — a critical requirement since corner seams experience higher stress than straight seams on rectangular containers. For higher-volume applications, Yongxin also provides a 6-roller square can automatic seamer with enhanced throughput.

FAQ
Q: What sizes of square cans can Yongxin’s square can making machine produce?
A: Yongxin’s small square can making line covers 0.5-5L rectangular tinplate containers. Custom tooling is available for specific dimensions within this range. For larger containers (10-20L), Yongxin offers separate large square can line configurations at 25-35 CPM.
Q: What is the production speed of the small square can making line 30-35 CPM?
A: The standard small square can making line operates at 30-35 cans per minute, suitable for small-to-medium production volumes. For higher throughput requirements, Yongxin can configure optimized line layouts with parallel processing stations.
Q: How does the 4 roller square can automatic seamer ensure seam quality on rectangular cans?
A: The 4-roller design distributes seaming pressure evenly across all four corners of the square can, where stress concentrations are highest. Each corner receives balanced first-operation and second-operation roller contact, producing consistent 5-layer double seams with hermetic integrity.
Q: Can the square can making line handle different can sizes with quick changeover?
A: Yes. The line supports changeover between can sizes within the 0.5-5L range by replacing tooling sets (dies, flanging wheels, seaming chucks). Typical changeover time is 2-4 hours depending on the size transition, with modular design facilitating faster adjustments.
Q: Does Yongxin provide installation support for international buyers?
A: Yes. Yongxin offers remote video guidance for installation and commissioning, with on-site engineer deployment available for bulk production line orders. Complete English-language documentation, electrical schematics, and operation manuals are provided with each machine.
Q: What is the typical lead time for a square can making machine order?
A: Standard equipment delivery is 45-60 days from order confirmation. Complete production line projects, including customization and testing, typically require 60-90 days. Exact timelines depend on configuration complexity and current production schedule.
Q: Is Yongxin qualified for international export?
A: Yes. Jiujiang Yongxin Can Equipment Co., Ltd. holds import & export trade qualifications, National High-Tech Enterprise certification, and has served buyers across Southeast Asia, the Middle East, Africa, and South America since 2005.
