🔥 High Output vs Low Output — The Real Gap in Filter Bag Tubing Lines

Why Most Chinese Tubing Lines Drop to 5 m/min —And Why KABORY’s High-Speed Tubing Line + Auto Filter Bag Sewing System Runs 10 m/min for Years

Whether you are new to filter bag manufacturing or upgrading an old factory, there is one industry truth you cannot ignore:

**❗ 90% of tubing lines from Chinese suppliers can only run at:

➡️ 5 m/min (long-term real production)**

You may hear them claim:

“⚡ Our machine can run 7–8 meters.”

But they never tell you the real story:

⏳ 8 m/min lasts only for the first 1–4 weeks
⏳ Drops to 6 m/min after 2–3 months
⏳ Falls to 5 m/min after 3–6 months
❗ And stays at 5 m/min permanently

This is not a coincidence.
It is a structural limitation of low-cost machines.

⚠️ Why LOW-COST Tubing Lines Always Drop to 5 m/min

1. ⛓ Chain Drive = Backlash + Wear + Vibration

Chain-driven systems have unavoidable defects:

  • ⚠️ Backlash grows with speed → feeding becomes unstable
  • ⚠️ Chain wear increases quickly → synchronization drifts
  • ⚠️ High temperature → chain expands → speed becomes inconsistent
  • ⚠️ More vibration → more needle breaks → operators forced to slow down

This is why suppliers dare to say:

“⚡ New machine can reach 8 meters.”

But they will NEVER promise:

“⚡ Still 8 meters after 6 months.”

Because it will NOT.

➡️ Real stable speed = 5 m/min

2. 🪵 Round-Tube Frame = Low Rigidity + Structure Bending

Most low-cost tubing lines use a round-tube welded frame:

  • Thin walls
  • Weak torsional strength
  • Long frame bends over time
  • Misalignment between forming → guiding → sewing
  • High-speed vibration increases dramatically

As a result:

⚠️ The faster it runs, the more unstable it becomes
➡️ Final stable speed = 5 m/min

3. ❌ No Closed-Loop Tension Control (Manual Only)

Low-cost machines CANNOT do:

  • No real-time tension feedback
  • No automatic compensation
  • No accumulator/buffer
  • No synchronization between feeding and sewing

So when operators try to run faster:

  • Fabric jerks
  • Stitch lines drift
  • Quality drops
  • Needle breakage rises

Operators finally slow it back to:

➡️ 5 m/min — the only speed that doesn’t cause defects

📉 Summary: Low-Cost = Always 5 m/min

8 m/min = demo speed
5 m/min = real speed

And this is why Chinese low-cost suppliers NEVER guarantee long-term speed —
they simply cannot.

**🚀 KABORY High-Speed Tubing Line:

10 m/min Stable for 5+ Years
Still 9–9.5 m/min in the 8th Year**

KABORY is the only manufacturer that openly guarantees long-term speed.

Why?

Because our system is built differently:

  • 🧱 Heavy-duty cast-iron / steel frame
  • 🎯 Synchronous-belt drive (no backlash, no wear)
  • 🔄 Real closed-loop tension control
  • 📦 Integrated accumulator
  • 🔧 Industrial-grade components
  • 🕒 Designed for 24/7 multi-shift production
  • 🛠 8–10 year mechanical lifespan

This is why KABORY can guarantee long-term speed.
Others cannot.

💡 Who Needs High-Speed Tubing Lines the Most?

1) New Factories

They quickly discover:

  • 5 m/min cannot support business growth
  • Too much manual work
  • Low efficiency and unstable quality
  • Hard to compete with faster factories

Industry lesson:

“Start with the right speed first, or you will buy twice.”

2) Old Factories Upgrading Capacity

Typical problems:

  • Old tubing lines dropped to 3–4 m/min
  • High downtime
  • Lack of factory space
  • Rising labor costs

KABORY solves all at once:

➡️ 1 KABORY line = 2 low-cost 5 m/min lines
➡️ No extra space
➡️ No extra labor
➡️ No extra utilities

Best ROI for mature factories.

📈 The Future: Not How Many Machines You Have — But What Speed You Run

Global trend is clear:

  • Slow factories lose orders
  • Fast factories take the market
  • Speed = Production power
  • Speed = Profit
  • Speed = Competitive advantage

5 m/min belongs to the past.
10–12 m/min defines the next decade.

🏁 Conclusion

LOW-COST Tubing Lines
➡️ New machine: 8 m/min (demo only)
➡️ 3–6 months later: 5 m/min
➡️ Long-term stable speed: 5 m/min

KABORY High-Speed Tubing Line
➡️ 10 m/min stable for 5+ years
➡️ 9–9.5 m/min even in year 8
➡️ One machine equals two low-cost lines

High speed is not about being “fast.”
It is about doubling output, doubling efficiency, and doubling competitiveness.
