1. Product Description
QVX-Straw Micro-Diameter Vacuum Instant-Quench Tunnel — purpose-built for plastic micro-tubes “as thin as a hair.”
Cooling Journey
When a ø2 mm PETG straw preform exits the die, it just needs a quick “cool shower” in the tunnel:
A slight vacuum first gives the tube a “yoga stretch,” instantly locking roundness;
Then stepped water temperatures apply an “ice-water mask,” dropping from 180°C to 35°C in 3 seconds to freeze the molecular chains in place;
At the outlet, you get crystal-clear straws with clean cuts, falling straight into the packaging machine.
2. Product Advantages
2.1 No Clogging in Fine Tubes
Stepless vacuum adjustment from -0.03 to -0.07 MPa; even ø1.6 mm medical tubing maintains a 100% clear bore rate.
2.2 No Winter Cracking
First stage at a constant 35°C relieves internal stress; PETG straw -20°C drop-test pass rate improves by 18%.
2.3 5-Minute Changeover
Quick-open hinged top cover with gas struts; single-handed lifting for threading—no more “unscrewing 48 bolts” pain.
2.4 Half the Power Consumption
Variable-frequency water-ring pump auto-downshifts by tube diameter; saves 26 kWh per 24-hour run—pays for itself in a year.
2.5 Quiet and Comfortable
Overall noise ≤58 dB; meetings in the next office can go on without closing doors and windows.
3. Product Features
3.1 Mirror-Grade 304 Liner
Ra ≤0.4 μm; food-grade weld polishing reduces bacterial residue by 90%.
3.2 Three Independent Water Temperatures
45°C → 25°C → 15°C; one-tap recipe switching on the touchscreen—no seasonal retuning required.
3.3 Drawer-Style Dual-Canister Filtration
200-mesh + 400-mesh stepped interception; 30-second screen changes without stopping the line.
3.4 Laser OD Feedback
Real-time data fed upstream to the extruder for automatic speed correction; tolerance ±0.02 mm.
3.5 Quick-Connect Drain Manifold
One-button drain at shift end; full-system cleaning in 3 minutes—no overnight odors.
4. Applications

7. User Reviews
7.1 Yield Surge on PLA Straws
“Our ø3 mm PLA straw roundness used to fluctuate. With this tunnel, first-pass yield jumped from 92% to 99.3%. We scrapped 8 tons less material in a year—payback achieved!” — Mr. Zheng, Production Director, Yiwu XX Biomaterials Co., Zhejiang
7.2 Cleaner for Medical PE Tubes
“Medical PE tubes are sensitive to particulates. The mirror-finish liner wipes spotless; particle counts dropped 70%, and the client waived the secondary cleaning step.” — Ms. Hu, QC Manager, Yangzhou XX Medical Tech, Jiangsu
7.3 Quieter Night Shifts
“Operators say it’s like ‘silent mode.’ The office next door measured 58 dB—finally no earplugs needed to chat.” — Mr. Wang, HR & Admin, Dongguan XX Straw Factory, Guangdong
One-Sentence Summary
QVX-Straw Micro-Diameter Vacuum Instant-Quench Tunnel enables ultra-fine plastic tubes to transform from “soft” to “tough” in just 3 seconds—saving material, power, and hassle.
