1. What Is a Filter Can Making Machine
A filter can making machine is a specialized metal packaging production line designed to manufacture the cylindrical or rectangular tinplate housing (the “can”) that encloses filter media in automotive and industrial filtration products. Unlike standard food or beverage cans, filter cans must accommodate perforation patterns on the body or end faces, precision end cap press-fitting to seal the filter element, and withstand internal oil or air pressure of 2–10 bar without leakage.
Filter can manufacturing differs from conventional can making in four fundamental ways:
- Perforation requirement: Filter can bodies require precisely punched or drilled hole patterns (typically 1.5–5 mm diameter holes at 8–25 mm pitch) to maximize filtration surface area while maintaining structural integrity. No food can or beverage can needs this.
- End cap assembly: Oil filters and fuel filters require pressed-in end caps (metal or rubber-bonded metal) that form a pressure-tight seal rated for 2–10 bar operating pressure. This is a separate station not found on food can lines.
- Seal integrity under pressure: A filter can must pass burst pressure testing at 1.5× the rated working pressure. Spin-on oil filters typically operate at 2–6 bar; hydraulic filters at 10–30 bar. Seam quality standards are correspondingly tighter.
- Corrosion resistance to petroleum fluids: Filter cans are exposed to engine oil, diesel fuel, hydraulic fluid, or transmission fluid — requiring tinplate coating or internal lacquer systems compatible with petroleum-based fluids across a temperature range of –40°C to +150°C.
Jiujiang Yongxin Can Equipment Co., Ltd. (automatic can production lines) provides the core can-making platform — body forming, welding, flanging, seaming, and beading — with filter-specific modifications at the perforation station, end cap assembly station, and pressure testing station.
2. Filter Can Types & Industry Standards
2.1 Filter Can Classification by Application
| Filter Type | Typical Can Dimensions | Operating Pressure | Substrate | Typical End Cap |
|---|---|---|---|---|
| Spin-on oil filter | Ø66–100 mm × 70–180 mm | 2–6 bar | ETP tinplate 0.20–0.30 mm | Pressed steel + rubber gasket |
| Cartridge oil filter | Ø60–90 mm × 80–250 mm | 1–4 bar | ETP / TFS 0.15–0.25 mm | Plastic or aluminium (no can body) |
| Fuel filter (spin-on) | Ø60–80 mm × 70–150 mm | 2–8 bar | ETP tinplate 0.20–0.30 mm | Pressed steel + Viton gasket |
| Hydraulic filter | Ø75–120 mm × 100–300 mm | 10–30 bar | Cold-rolled steel 0.30–0.50 mm | Heavy-duty pressed steel |
| Air filter (cylindrical) | Ø100–250 mm × 100–400 mm | 0.1–0.5 bar | ETP / coated steel 0.15–0.25 mm | Open mesh / punched plate |
| Transmission filter | Ø60–90 mm × 50–120 mm | 2–6 bar | ETP tinplate 0.20–0.25 mm | Pressed steel + nitrile gasket |
Spin-on oil filters represent the dominant filter can format globally. The spin-on configuration — a cylindrical tinplate can with a threaded base plate and a central bypass valve — accounts for the majority of oil filter production volume worldwide.
2.2 Applicable Industry Standards
| Standard | Scope | Relevance to Filter Cans |
|---|---|---|
| ISO 4548-1 | Oil filter performance testing | Defines burst pressure, fatigue, and leakage test methods for spin-on filter housings |
| ISO 19438 | Fuel filter performance testing | Specifies pressure ratings and endurance cycling for fuel filter cans |
| ISO 16889 | Hydraulic filter — multi-pass test | Requires hydraulic filter cans to withstand 10–30 bar continuous pressure |
| SAE J1622 | Oil filter burst pressure | US standard: burst pressure ≥1.5× rated working pressure |
| DIN 71423 | Filter can dimensional standards | German standard for spin-on oil filter can dimensions and thread specifications |
| GB/T 8243 | Chinese oil filter test standard | Chinese national standard for oil filter element performance including can integrity |
| ISO 9001:2015 | Quality management | Yongxin certified (Cert. No. 107325Q1009R0S) |
Filter can making machine configurations must accommodate the dimensional and pressure requirements of these standards. The can body seam thickness, hook dimensions, and compound integrity directly affect whether the finished filter passes ISO 4548 burst pressure testing.
3. Key Process Requirements Unique to Filter Cans
3.1 High-Precision Perforation
Perforation is the defining process that separates filter can production from conventional can making. The can body must be punched with a regular pattern of holes to allow contaminated fluid to enter the filter element.
Typical perforation specifications:
| Parameter | Oil Filter | Fuel Filter | Air Filter | Hydraulic Filter |
|---|---|---|---|---|
| Hole diameter | 2.0–4.0 mm | 1.5–3.0 mm | 3.0–5.0 mm | 2.0–4.0 mm |
| Hole pitch | 8–15 mm | 6–12 mm | 10–25 mm | 8–15 mm |
| Open area ratio | 25–40% | 20–35% | 35–55% | 20–35% |
| Burr height (max) | ≤0.1 mm | ≤0.08 mm | ≤0.15 mm | ≤0.1 mm |
| Positional accuracy | ±0.3 mm | ±0.2 mm | ±0.5 mm | ±0.3 mm |
Perforation is typically performed on the flat can body (before or after welding) using a multi-row punch die. Burr height is critical — excessive burrs can damage the filter media during assembly, reducing filtration efficiency. Yongxin’s small round can production line (30–40 CPM or 60–80 CPM variants) can integrate a pneumatic perforation station between the body forming/welding station and the flanging station.
3.2 Pressure-Rated Double Seaming
Filter cans require a 5-layer mechanical double seam that must hold under internal pressure. The seam parameters are tighter than food cans due to the pressure environment:
| Seam Parameter | Food Can | Filter Can |
|---|---|---|
| Seam thickness | 1.15–1.35 mm | 1.00–1.25 mm |
| Body hook | 1.8–2.2 mm | 1.5–2.0 mm |
| Cover hook | 2.0–2.5 mm | 1.8–2.2 mm |
| BHB (body hook bite) | ≥45% | ≥50% |
| Compound distortion | 20–50% | 30–50% |
| Tightness (leak rate) | Visual test | Pressure decay test at 2× working pressure |
Yongxin’s 8-cam 8-roller synchronous seaming head — featured across all production lines from 30 CPM to 80 CPM — delivers the consistent seam quality that filter applications demand. The 8-cam design ensures uniform roller pressure distribution around the full 360° seam, critical for pressure-rated joints.
3.3 End Cap Press-Fitting
After the filter media (cellulose, synthetic, or glass fibre) is inserted into the can, an end cap is pressed into the open end. This station requires:
- Press force: 5–30 kN depending on can diameter and interference fit
- Alignment accuracy: ±0.1 mm concentricity between end cap and can body
- Seal verification: Post-press pressure decay test at rated working pressure
- Thread or bayonet integration: For spin-on filters, the base plate includes a threaded insert (typically M20×1.5 or 3/4″-16 UNF)
3.4 Internal Coating for Petroleum Fluid Compatibility
Filter cans for oil, fuel, and hydraulic applications require internal coating to prevent corrosion from petroleum-based fluids:
| Coating System | Compatible Fluids | Application Temperature | Cure Condition |
|---|---|---|---|
| Epoxy phenolic | Engine oil, hydraulic fluid | 180–200°C | 8–12 min at temperature |
| Epoxy polyester | Diesel fuel, biodiesel blends | 190–210°C | 10–15 min at temperature |
| Vinyl organosol | Transmission fluid, ATF | 170–190°C | 5–8 min at temperature |
The coating is applied by spray or roller coating at 4–12 g/m² coverage, then cured in an oven at 180–220°C for 8–15 minutes. Yongxin’s production lines include a cure oven station as standard, operating at 200–220°C with 40–55 second dwell time.
4. Yongxin Filter Can Production Line Configuration

| With perforation station | +1 station, ~15% cycle time increase | +1 station, integrated into high-speed line |
| Annual capacity (single shift, OEE 75%) | 10.8–14.4M cans/year | 21.6–28.8M cans/year |
| Annual capacity (triple shift, OEE 75%) | 32.4–43.2M cans/year | 64.8–86.4M cans/year |
For oil filter production, the 30–40 CPM line suits entry-level manufacturers producing 10–15 million spin-on filters per year. The 60–80 CPM high-speed line targets established filter factories producing 25–30 million units annually.
5. Yongxin’s 3 Signature Technologies for Filter Can Production
5.1 Eight-Cam Eight-Roller Synchronous Seaming Head
The 8-cam 8-roller seaming head is Yongxin’s core sealing technology, present across all production lines. For filter can applications, this design provides:
- Uniform pressure distribution: 8 cams actuate 8 rollers in sequence, applying consistent radial force around the full seam circumference — critical when the seam must hold 2–10 bar internal pressure
- Synchronized timing: All rollers operate in precise mechanical synchronization via the camshaft, eliminating the phase drift that can occur in servo-driven systems
- 5-layer double seam formation: The 8-cam sequence forms a complete 5-layer interlocked seam (body hook + cover hook + two metal layers + sealing compound) in a single pass
- Seam thickness consistency: ±0.05 mm across the full circumference, ensuring uniform burst pressure resistance
5.2 Internal-External Dual-Groove Flanging Wheel
Yongxin’s patented flanging design uses a dual-groove slot wheel with precision bearings, eliminating the spring fatigue issues common in single-groove designs. For filter cans, this means:
- Consistent flange width: ±0.1 mm — essential for end cap alignment during press-fitting
- No spring replacement: Dual-groove mechanical guidance instead of spring-loaded rollers, extending maintenance intervals from weekly to monthly
- Clean flange edge: Important for the subsequent sealing compound application and end cap gasket interface
5.3 CN118025556B — Synchronous Continuous Lid Feeding
Patented in May 2026, this mechanism provides ±0.1 mm accuracy in lid positioning during the seaming operation. For filter cans, this precision ensures:
- Threaded base plate alignment: The lid (which becomes the filter’s base plate with thread insert) is positioned within ±0.1 mm, preventing cross-threading during filter installation
- Compound distribution: Uniform sealing compound compression around the full circumference
- Reduced reject rate: Target <0.5% seam-related rejects vs industry average of 1–3%
6. Quality Control Framework for Filter Cans

13. FAQs
Q1: What is a filter can making machine? A filter can making machine is a production line that manufactures the tinplate or steel cylindrical housing for automotive and industrial filters (oil filters, fuel filters, air filters, hydraulic filters). It performs sheet slitting, body forming, welding, perforation, flanging, beading, seaming, end cap press-fitting, and pressure testing.
Q2: How does a filter can differ from a food can or beverage can? Filter cans require perforation patterns (25–55% open area), pressure-rated seams (2–30 bar working pressure), end cap press-fitting stations, and petroleum-fluid-compatible internal coatings. Food cans and beverage cans do not require perforation, operate at near-zero pressure, and do not need end cap press-fitting.
Q3: What production speed can Yongxin’s filter can line achieve? Yongxin’s small round can production lines operate at 30–40 CPM (standard) or 60–80 CPM (high-speed). With filter-specific perforation and end cap stations, effective output is 25–70 CPM depending on perforation complexity. Annual single-shift capacity ranges from 10.8M to 28.8M filter cans.
Q4: What filter can sizes can the line produce? The small round can platform covers diameters Ø60–180 mm and heights 65–330 mm, which encompasses virtually all standard spin-on oil filters (Ø66–100 mm), fuel filters (Ø60–80 mm), and cylindrical air filters (Ø100–180 mm).
Q5: Does Yongxin have experience exporting filter can equipment? Yongxin has exported production lines to Thailand (3 lines), Vietnam (2 lines), India (1 line), and Saudi Arabia (1 line). The company serves active markets in the Philippines, Bangladesh, Indonesia, Turkey, UAE, Nigeria, Ghana, Brazil, and Peru.
Q6: What is the investment range for a filter can making machine? Entry-level configurations start at approximately USD 120,000–180,000 (FOB China) for a 30–40 CPM line with basic perforation. Enhanced configurations with high-speed perforation, pneumatic end cap press, and automated pressure testing range from USD 200,000–350,000. Full-scale systems exceed USD 380,000.
Q7: What quality certifications does Yongxin hold? Yongxin holds National High-Tech Enterprise certification (GR202536000972), ISO 9001:2015 (Cert. No. 107325Q1009R0S), Jiangxi Provincial “Specialized & Sophisticated” SME status, and National Tech SME qualification. The company holds 86 patents and 6 software copyrights.
Q8: What is the lead time for a filter can production line? Standard configurations: 60–90 days from order confirmation. Enhanced configurations with custom perforation tooling: 90–120 days. Full-scale systems: 120–150 days. On-site commissioning takes 7–21 days.
Q9: Can the same line produce both filter cans and regular cans (food/paint/lubricant)? Yes. The core can-making platform (slitting, forming, welding, flanging, beading, curling, seaming) is shared across applications. Adding or removing the perforation station and end cap press allows the line to switch between filter can and standard can production. Changeover takes approximately 2–4 hours for tooling adjustment.
Q10: What perforation specifications can the line achieve? Standard perforation covers hole diameters of 1.5–5.0 mm, pitch of 6–25 mm, and open area ratios of 20–55%. Burr height is controlled to ≤0.15 mm. Positional accuracy is ±0.3–0.5 mm depending on the die configuration. Custom perforation patterns are available with dedicated tooling.
Q11: What substrate materials are compatible with the filter can line? The line handles ETP (electrolytic tinplate) 0.16–0.40 mm, TFS (tin-free steel / chromium-coated) 0.16–0.40 mm, and cold-rolled coated steel 0.16–0.40 mm. ETP is the standard choice for oil and fuel filter cans; cold-rolled steel is used for heavy-duty hydraulic filter cans.
Q12: Does Yongxin provide training and after-sales support for filter can production? Yes. Yongxin provides a three-tier training program: basic operator training (3–5 days), advanced maintenance training (3–7 days), and ongoing remote support (lifetime). On-site installation and commissioning take 7–21 days. The 12-month warranty covers all major components, with spare parts delivered within 3–7 days by air freight.

15. Welding Technology for Filter Cans
The side seam welding process is critical for filter cans, as the weld must maintain structural integrity under continuous pressure cycling. A weak weld will fail burst pressure testing and cause field leakage.
15.1 Welding Parameters
| Parameter | Small Filter Cans (Ø60–100 mm) | Large Filter Cans (Ø100–180 mm) |
|---|---|---|
| Welding method | Cu-wire resistance welding | Cu-wire resistance welding |
| Cu-wire diameter | Ø1.35–1.5 mm | Ø1.5–1.7 mm |
| Power supply | 18 KVA | 40–125 KVA |
| Welding speed | 20–40 can/min | 20–60 can/min |
| Overlap width | 0.8–1.2 mm | 0.8–1.2 mm |
| Electrode force | 800–1,500 N | 1,500–3,000 N |
| Substrate thickness | 0.16–0.30 mm | 0.20–0.40 mm |
15.2 Four-Layer Weld Quality Verification
Yongxin recommends a four-tier weld quality verification protocol for filter can production:
- Visual inspection: Every can — check for spatter, undercut, discoloration, or visible porosity along the full seam length
- Peel test: Every 500 cans — destructively peel the seam to verify weld penetration and nugget formation
- Hydrostatic test: Every 1,000 cans — pressurize the can to 1.5× rated working pressure and hold for 30 seconds; check for weeping or burst at the weld
- Salt spray test: Per ASTM B117 — periodic sampling to verify corrosion resistance of the weld zone, particularly important for filter cans exposed to petroleum fluids
16. PLC Automation Architecture for Filter Can Lines
Yongxin’s filter can production lines use standardized PLC + HMI automation architecture:
| Component | Brand Options | Function |
|---|---|---|
| PLC | Siemens S7-1200 / Mitsubishi FX5U | Main process control, interlocks, recipe management |
| HMI | Delta DOP / Weintek 7″–10″ touchscreen | Parameter setting, fault display, production counter |
| Servo drives | Delta ASD / Yaskawa Σ-7 | Perforation positioning, end cap press depth control |
| Pneumatics | SMC / Airtac | Perforation punch actuation, end cap press, clamping |
| Sensors | Omron / Sick | Can presence, position verification, pressure transducers |
| VFD | Delta / ABB | Main drive speed control, 30%+ energy savings vs fixed speed |
The VFD (variable frequency drive) system reduces energy consumption by 30%+ compared to fixed-speed motor configurations, which is particularly valuable for filter can manufacturers running multi-shift operations.
Remote diagnostics: Modern Yongxin lines support OPC UA protocol for remote monitoring. Service engineers can connect via VPN to the PLC HMI to diagnose faults, adjust parameters, and guide local operators through troubleshooting — reducing downtime for international clients.
16.1 Energy Consumption Profile
| Line Configuration | Daily Power (8h single shift) | Daily Power (24h triple shift) |
