Stainless Steel Vacuum Spray Water Cooling Tank — Achieve Instant Sizing for PTFE/PETG/PLA Pipes and Straws

I. Product Description

Imagine this: a freshly extruded thermoplastic pipe is swiftly guided into a fully sealed stainless-steel “tunnel.” Inside, a stable vacuum and enveloping water mist work together—no more trembling of hot pipes, the outer diameter is instantly locked, and the surface becomes mirror-smooth. This is our vacuum spray water cooling tank, purpose-built for high-performance pipes such as PTFE, PETG, and PLA. Like a calm and precise steward, it perfects the “last mile” of sizing and cooling, ensuring every meter of pipe achieves millimeter-level precision and a mirror-like finish, ready to connect directly to cutting, winding, or in-line inspection.

II. Product Advantages

1. Instant cooling: High-density 360° annular spray boosts heat exchange efficiency by 35%. At the same line speed, the tank length can be shortened by 20%, saving floor space.

2. Vacuum stabilization: ±0.003 MPa micro-negative pressure with closed-loop control enables “zero-gravity” uniform shrinkage of the hot melt tube blank; ovality ≤ 0.2 mm.

3. All-stainless “skeleton”: SUS304 inner liner and wetted parts resist chloride corrosion, delivering a service life of 10+ years and eliminating “rust contamination.”

4. One-touch size change: Quick-release nozzles and hinged viewing windows enable size changes in 3 minutes—perfect for small, multi-spec orders with zero waiting.

5. Smart energy saving: VFD pump and real-time temperature control save ≈ 2800 kWh per year; filtered recirculating water cuts consumption by 60%.

6. Quiet and safe: Double-layer insulated housing and low-noise centrifugal fans keep on-site noise ≤ 75 dB, giving operators a “quiet summer.”

III. Core Features

• Modular length: 2 m per section, stackable like “LEGO”—from 2 m to 12 m to suit different line speeds.

• Multi-zone independent temperature control: Front-end warm cooling to prevent whitening; rear-end fast cooling to lock dimensions. Temperature gradients can be set by “dragging” on the touchscreen.

• Real-time visible vacuum: Digital vacuum gauge plus LED indicators; abnormal vacuum triggers alarm and stop within 0.1 s to prevent batch scrap.

• Quick-release filter basket: 200-mesh stainless mesh; remove and clean in 30 seconds, blocking impurities from recirculating and keeping nozzles unclogged.

• Compatible with multiple materials: PTFE (high-temperature resistant), PETG (high transparency), PLA (biodegradable)—all supported. Switching formulas only requires calling the “process package.”

IV. Typical Applications

• Medical catheters: PTFE capillary tubes with OD 0.8–6 mm; ovality ≤ 0.02 mm for interventional devices.

• Food-grade straws: PETG/PLA transparent straws Ø4–12 mm, no streaks or water marks, resistant to 90 °C hot water.

• 3D printing filament: PLA filament Ø1.75 ± 0.02 mm, roundness ≥ 95%, directly spooled without secondary haul-off.

• Industrial liners: PTFE-lined oil pipes Ø25–75 mm, continuous lengths up to 100 m, no stress cracking.

V. Shipping and Delivery

• Export-grade wooden crates with moisture-proof vacuum bags; internal 3D foam fixtures withstand a 1.5 m drop test.

• Flexible FCL/LCL options: Six 2 m standard sections can be stacked into one 20GP container, saving 30% on freight.

• “Tool kit” included: 5 spare nozzles, 10 seal sets, and bilingual (CN/EN) quick-start guide; on-site assembly and water hookup completed in 30 minutes.

VII. Real User Feedback

“We produce PLA straws and used to rely on open water tanks—ovality was always unstable. After switching to this vacuum spray tank, ovality dropped from 0.4 mm to 0.15 mm. Customers approved at first inspection, and rework rate went straight to zero!”
— Mr. Li, Biodegradable Straw Manufacturer, Dongguan

“Medical PTFE catheters require exceptional cleanliness. The stainless liner and quick-release filter design are incredibly user-friendly. Weekly checks take just 10 minutes, and the GMP auditor gave it a perfect score.”
— Mr. Wang, Quality Manager, Medical Device Company, Wuxi, Jiangsu

“The equipment shipped to Mexico by sea for 40 days—the crate was intact. It was plug-and-play on site; with the English interface, our technician learned it in 15 minutes. After-sales service needed = 0—truly worry-free!”
— Carlos, Extrusion Equipment Distributor, South America
