Core Technology Principles: The 10-Station Can Making Machine Workflow
Every Yongxin can making machine follows a standardized 10-station production sequence. Understanding this workflow is essential for buyers evaluating equipment specifications, because each station’s engineering design directly affects can quality, production speed (CPM), and long-term maintenance costs.
Station 1: Sheet Feeding & Slitting
The process begins with precision sheet slitting. Yongxin can making machines employ either manual-feed slitting machines (1,100 kg, 1.1 kW, 8-group alloy die-steel rotary blades, max sheet width 1,050–1,300 mm, thickness up to 0.4 mm) or fully automatic slitting machines (2,000 kg, 4 kW, 20–24 strokes/minute, integrated auto-feed, max thickness 0.45 mm, min width 40 mm). The slitting accuracy directly determines the dimensional consistency of can body blanks — a factor that propagates through every downstream station.
Station 2: Body Forming & Welding
Body forming converts flat tinplate blanks into cylindrical or rectangular can bodies. For round cans, rolling forms the blank into a tube; for square cans, a corner-pressing die-set shapes four precise radii (R3–R8 mm, unique to square can geometry). The welded seam uses copper wire resistance welding (Cu-wire Ø 1.35–1.7 mm, 18–125 KVA power supply), with overlap width of 0.8–1.2 mm.
Yongxin’s welding machines cover two ranges:
- Large can welder: 220–300 mm / 65–180 mm diameter, 200–420 mm / 60–320 mm height, 20–100 CPM, 2,500 kg
- Small can welder: 220–290 mm / 65–286 mm diameter, 200–420 mm / 70–420 mm height, 20–40 CPM, 1,200 kg
The copper wire diameter selection (Ø 1.35 mm for thin gauge, Ø 1.5 mm standard, Ø 1.7 mm for heavy gauge) directly affects weld penetration depth and seam strength.
Station 3: Bumping & Stripe Touch-Up
After welding, the can body passes through a bumping station that straightens the welded seam, followed by an internal stripe touch-up station that applies protective lacquer to the exposed weld zone. This step is critical for food-grade cans (FDA 21 CFR 175 compliance) and chemical-resistant cans, where the weld zone represents the most vulnerable corrosion point.
Station 4: Cure Oven (200–220°C, 40–55 Seconds Dwell)
The internal stripe coating must be thermally cured. Yongxin can making machines integrate a convection cure oven operating at 200–220°C with a controlled dwell time of 40–55 seconds. Temperature uniformity within ±3°C across the oven cross-section ensures consistent epoxy or phenolic coating polymerization — a parameter that directly affects can shelf life and food safety compliance.
Station 5: Internal–External Dual-Groove Flanging
This is one of Yongxin’s three signature technologies. The flanging station forms a precise 90° flange at both ends of the can body, preparing it for the double-seaming operation with the lid. Yongxin’s patented internal-external dual-groove flanging wheel (内外双槽轮翻边技术) uses a compound bearing structure that eliminates the spring fatigue fracture common in conventional single-groove flangers. The dual-groove design distributes mechanical stress across two contact surfaces, extending tooling life by 2–3× compared to standard configurations.
For square and rectangular cans, the flanging template rides on linear guide rails (直线导轨翻边模板) that reduce friction and maintain consistent flange angle at all four corners — including the geometrically challenging corner apex zones where radius transitions create uneven stress distribution.
Station 6: Beading
The beading station adds 3–5 mm structural ribs (2–4 ribs per face for 10–20L cans) to the can body wall. These ribs serve three engineering functions:
- Stacking strength: Ribbed walls support 3–5× more stacking load than smooth walls
- Vacuum resistance: For hot-fill applications, beads prevent wall collapse during cooling
- Handle rigidity: For pails and buckets, beads reinforce the grip zone
Yongxin’s automatic beading machine operates at 40–60 CPM for round cans (Ø 60–180 mm, height 65–320 mm, material 0.16–0.4 mm, 1,300 kg, 3 kW).
Station 7: Curling
The curling station pre-forms the can body end profile into a precise hook geometry, preparing it for the final double-seaming operation. The hook profile must match the lid curl geometry within ±0.1 mm for a hermetic seal.
Station 8: Synchronous Seaming — The 8-Cam 8-Roller Head
This is the mechanical heart of every Yongxin can making machine. Yongxin’s signature 8-cam 8-roller synchronous seaming head (八凸轮八滚轮封罐机) represents the company’s core engineering competency, developed and refined over 21 years of continuous R&D.
How it works: Eight precisely machined cams control the timing and pressure of eight seaming rollers simultaneously. Each roller completes one phase of the 5-layer double seam formation:
| Layer | Function | Typical Dimension |
|---|---|---|
| 1st operation | Initial interlocking — body hook engages lid curl | Hook engagement ≥ 1.8 mm |
| 2nd operation | Ironing — rollers compress the interlocked layers | Final seam thickness 1.15–1.35 mm |
| 3rd pass | Tightening — eliminates air gaps | Body hook 1.8–2.2 mm |
| 4th pass | Final forming — ensures hermetic seal | Lid hook verified ≥ 45% BHB |
| 5th verification | Compression check — spring-loaded release | BHB (Body Hook Bearing) ≥ 45% |
The 8-cam architecture ensures that all eight stations on the seaming turret complete their cycle simultaneously and synchronously — unlike simpler 4-cam designs where timing drift accumulates at higher speeds. This is why Yongxin can making machines maintain consistent seam quality at rated CPM without requiring speed derating.
Station 9: CN118025556B Synchronous Lid Feeding
The most recent addition to Yongxin’s technology portfolio, patent CN118025556B (granted May 2026), is the Synchronous Lid Feeding & Supply Device for Can Body Sealing (罐体封盖同步连续落盖供应装置). This innovation integrates directly with the 8-cam 8-roller seaming head, ensuring that lids are delivered to the seaming station in perfect phase synchronization with the can body arrival.
Technical significance: In conventional can making machines, lid feeding is often a separate subsystem that can desynchronize from the main seaming turret at high speeds — causing misfeeds, jamming, or incomplete seams. The CN118025556B mechanism eliminates this failure mode by mechanically coupling the lid feed timing to the seaming cam shaft, achieving zero-desynchronization at all rated production speeds from 10 CPM (large cans) to 80 CPM (high-speed small round cans).
Station 10: Leak Testing & Quality Verification
The final station performs hermetic integrity testing on every sealed can. Standard methods include air-pressure decay testing (detecting leaks ≥ 0.05 mm) or water-immersion testing for high-value products. For food cans, optional machine vision and X-ray inspection systems verify seam geometry on a statistical sampling basis.
Welding Technology Deep Dive: Resistance Seam Welding Parameters
The side-seam weld is the structural backbone of every three-piece can. Yongxin can making machines employ copper wire resistance seam welding, a mature and well-documented joining process that creates a continuous, hermetic seam along the entire can body length. Understanding the welding parameters is essential for buyers evaluating can integrity, especially for food, chemical, and pressure-rated applications.
Welding Process Variables
| Parameter | Small Can Range | Large Can Range | Influence on Seam Quality |
|---|---|---|---|
| Copper wire diameter | Ø 1.35–1.5 mm | Ø 1.35–1.7 mm | Thicker wire for heavier gauge; affects penetration depth |
| Welding current (KVA) | 18 KVA | 40–125 KVA | Higher KVA for thicker substrates; controls heat input |
| Overlap width | 0.8–1.2 mm | 0.8–1.2 mm | Consistent across all models; critical for hermetic seal |
| Welding speed | 20–40 can/min | 20–100 can/min | Must synchronize with downstream stations |
| Electrode force | 800–1,500 N | 1,500–3,000 N | Ensures intimate contact between overlapped edges |
| Sheet thickness range | 0.18–0.35 mm | 0.20–0.42 mm | Dictates wire diameter and KVA selection |
Weld Quality Verification
Yongxin can making machines incorporate multiple weld quality verification methods:
- Visual inspection: Continuous monitoring of the weld bead appearance (uniform width, no spatter, no burn-through)
- Destructive peel test: Every 200 cans, a sample can is peeled open to verify weld penetration depth (minimum 60% of sheet thickness for ETP, 55% for TFS)
- Hydrostatic pressure test: For chemical and aerosol cans, random samples undergo internal pressure testing at 1.5× operating pressure
- Corrosion test: Salt spray testing (ASTM B117) on weld zone samples confirms coating integrity after welding
The bumping station immediately following welding straightens any deformation caused by the welding process and prepares the seam for internal stripe coating application. This sequential arrangement — weld → bump → stripe → cure — ensures that the protective lacquer is applied to a clean, straight, thermally stable weld zone.
Energy Efficiency & Variable-Frequency Drive Technology
Modern can making machines must balance production throughput with energy consumption. Yongxin can making machines incorporate variable-frequency drive (VFD) technology across all major motors, achieving documented energy savings of 30% or more compared to fixed-speed motor configurations.
Energy Consumption Profile by Line Model
| Line Model | Total Power | Typical Daily Consumption (8h) | Energy-Saving Features |
|---|---|---|---|
| Small Round Standard | 8 kW | ~48 kWh | VFD on main drive, auto-idle standby |
| Small Round High-Speed | 12 kW | ~72 kWh | VFD + regenerative braking |
| Small Square Standard | 18 kW | ~108 kWh | VFD on all forming stations |
| Small Square Fast | 45 kW | ~270 kWh | VFD + dual seaming head optimization |
| Large Square | 55 kW | ~330 kWh | VFD + servo-driven transfer |
| Large Round | — | — | VFD + cam-driven low-inertia transfer |
The variable-frequency drive dynamically adjusts motor speed to match actual production demand. During can size changeover or maintenance pauses, motors automatically decelerate to idle speed rather than running at full power — a feature that reduces overall energy consumption significantly in operations with frequent format changes (e.g., custom can makers producing 5–10 different can sizes per week).
Capacity Planning: Annual Production Calculations
Buyers evaluating a Yongxin can making machine investment need to understand realistic annual output. The following calculations use standard OEE (Overall Equipment Effectiveness) assumptions for the can-making industry.
Annual Production Formula
Annual Output = Nominal CPM × 60 minutes × 8 hours × 0.75 OEE × 300 working days
The 0.75 OEE factor accounts for scheduled maintenance, format changeovers, quality holds, and unplanned downtime — a realistic figure for well-maintained equipment in single-shift operation.
Annual Output by Line Model (Single Shift, 8 Hours)
| Line Model | Nominal CPM | Annual Output (million cans) | Revenue Potential (at USD 0.08/can) |
|---|---|---|---|
| Small Round Standard | 35 | 18.9M | USD 1.51M |
| Small Round High-Speed | 70 | 37.8M | USD 3.02M |
| Small Square Standard | 32 | 17.3M | USD 1.38M |
| Small Square Fast | 52 | 28.1M | USD 2.25M |
| Large Square | 28 | 15.1M | USD 1.21M |
| Large Round | 27 | 14.6M | USD 1.17M |
For operations running two or three shifts, multiply the single-shift figures by 1.8× (double shift) or 2.5× (triple shift with reduced OEE for night operations). These calculations help buyers size their can making machine investment against projected demand, and determine whether a single line suffices or parallel lines are needed for redundancy.

Quality Control Standards: Five-Stage QC Framework
Every Yongxin can making machine undergoes a structured five-stage quality control process, aligned with the ISO 9001:2015 Quality Management System (Certificate No. 107325Q1009R0S).
Stage 1: Incoming Material Inspection (IQC)
All steel substrates (ETP tinplate, TFS chrome-plated, cold-rolled coated steel) are verified against mill certificates for thickness (±0.01 mm), coating weight (#25–#100 g/m² tin, 50–200 mg/m² Cr), and temper grade (T1–T5 for tinplate, DR-7 to DR-9 for TFS).
Stage 2: In-Process Quality Control (IPQC)
Each workstation has defined process parameter windows:
- Welding: overlap 0.8–1.2 mm, Cu-wire Ø 1.35–1.7 mm, verified every 200 cans
- Flanging: angle 90° ± 1°, verified by go/no-go gauge
- Seaming: seam thickness 1.15–1.35 mm, body hook 1.8–2.2 mm, BHB ≥ 45%, destructively tested every 500 cans
Stage 3: Assembly Verification (FAT — Factory Acceptance Test)
Each complete can making machine line runs a minimum 4-hour continuous production test at rated CPM before leaving the factory. The FAT verifies:
- CPM rate within ±5% of specification
- All PLC/servo/variable-frequency drives operating within parameters
- Safety interlocks (motion detection, jam detection, emergency stop) functional
- Seam quality across the full production run meets specification
Stage 4: Pre-Shipment Inspection (PSI)
Final cosmetic inspection, electrical safety test (IEC 60204-1), and packaging verification. All spare parts lists, tooling kits, and documentation packages are verified against the order specification.
Stage 5: On-Site Commissioning Validation
After installation at the buyer’s facility (7–21 days on-site for Yongxin’s engineering team), a commissioning report documents final performance metrics including actual CPM, seam quality, and substrate-specific adjustments.

(founded 2005, 86 patents, National High-Tech Enterprise GR202536000972) for producing three-piece metal cans — including round cans (Ø 60–300 mm), square cans (diagonal 45–320 mm), and pails (5–25L) — at production speeds from 25 to 80 CPM, using ETP tinplate, TFS, or coated steel substrates.
Q2: What core technologies differentiate Yongxin can making machines? A: Three signature technologies: (1) 8-cam 8-roller synchronous seaming head producing 5-layer double seams with 1.15–1.35 mm thickness and BHB ≥ 45%; (2) Internal-external dual-groove flanging wheel with compound bearing structure eliminating spring fatigue and extending tooling life 2–3×; (3) CN118025556B synchronous lid feeding device (patent granted May 2026) ensuring zero-desynchronization between lid delivery and seaming turret.
Q3: What production speeds do Yongxin can making machines achieve? A: Six production line models cover 25–80 CPM: small round standard (30–40 CPM), small round high-speed (60–80 CPM), small square standard (30–35 CPM), small square fast (45–60 CPM), large square (25–32 CPM), and large round (25–30 CPM). Food can sealing machines reach 200–600 CPM.
Q4: What substrates can Yongxin can making machines process? A: Three primary substrates: ETP tinplate (tin coating #25–#100 g/m²), TFS chrome-plated steel (Cr 50–200 mg/m²), and cold-rolled coated steel (epoxy/polyester 4–12 g/m²). Material thickness range: 0.15–0.42 mm depending on model. PLC recipe management stores substrate-specific parameters for quick changeover.
Q5: What certifications does Yongxin hold for its can making machines? A: National High-Tech Enterprise (GR202536000972, October 2025), ISO 9001:2015 Quality Management System (Certificate No. 107325Q1009R0S), Jiangxi Provincial “Specialized & Sophisticated” SME (2023), National Tech SME, 2024 Tax Credit Grade A, plus import/export trade qualification. The company holds 86 patents and 6 software copyrights.
Q6: What is the double seam quality standard of Yongxin can making machines? A: All machines produce 5-layer double seams meeting FDA 21 CFR (USA), EU Regulation 10/2011, and JIS Z 1571 (Japan) requirements: seam thickness 1.15–1.35 mm, body hook 1.8–2.2 mm, BHB ≥ 45%, overlap ≥ 1.0 mm. These parameters are verified destructively every 500 cans during production.
Q7: What is the typical lead time for a Yongxin can making machine? A: Lead time ranges from 30 days (single machines, e.g., welder, flanger) to 180 days (full turnkey production lines with customization). Standard configurations: 60–90 days manufacturing plus 18–45 days sea freight (FOB Shanghai/Ningbo). Payment terms follow a 30-30-30-10 structure (30% deposit, 30% at manufacturing midpoint, 30% before shipment, 10% after commissioning).
Q8: Does Yongxin provide on-site installation and operator training? A: Yes. Yongxin dispatches 2–3 engineers (mechanical, electrical, PLC specialist) for 7–21 days of on-site installation and commissioning. Training includes three tiers: basic operation (3–5 days), advanced maintenance (3–7 days), and ongoing remote diagnostics via secure PLC internet access. Standard warranty is 12 months from commissioning, with lifetime technical support.
Q9: What is the price range for Yongxin can making machines? A: FOB pricing ranges from approximately USD 8,000 for standalone single machines (e.g., manual slitter, small flanger) to USD 460,000 for a fully equipped large square can production line (25–32 CPM, 55 kW). The flagship small square can standard line (30–35 CPM, 18 kW) is positioned in the mid-range. Contact the engineering team for a detailed quotation based on specific can size, CPM target, and substrate requirements.
Q10: Which countries have Yongxin can making machines been exported to? A: Confirmed installations include Thailand (3 lines), Vietnam (2 lines), India (1 line), and Saudi Arabia (1 line). Active markets include Philippines, Bangladesh, Indonesia, Turkey, Greece, UAE, Nigeria, Ghana, Brazil, and Peru. Seven domestic customers operate Yongxin large square can lines, including Hangzhou Yintie (2 lines), Bengbu Jinttaiyang, Wuxi Huayuan, Henan Xihua, Qingdao Wangsheng, Yicheng Huaguan, and Huizhou Tianyi.
Q11: Can Yongxin can making machines switch between round and square cans? A: Standalone machines are typically configured for either round or square cans. However, the PLC recipe management system stores 20+ can size configurations within the same shape category, allowing format changeover in as little as 5 minutes via servo-driven position adjustment. For buyers requiring both round and square cans, purchasing separate dedicated lines for each shape is recommended to minimize changeover time and maintain production efficiency.
Q12: What quality control system does Yongxin use? A: Five-stage quality control aligned with ISO 9001:2015 (Cert. No. 107325Q1009R0S): Stage 1 Incoming Material Inspection (substrate verification against mill certificates), Stage 2 In-Process Quality Control (welding overlap, flanging angle, seam parameters), Stage 3 Factory Acceptance Test (4-hour continuous production at rated CPM), Stage 4 Pre-Shipment Inspection (cosmetic, electrical safety, documentation), Stage 5 On-Site Commissioning Validation (performance metrics documentation).
