Stainless Steel Vacuum Water Cooling Tank — Keep PTFE/PETG/PLA Pipes and Straws “Cool” and Precisely Shaped

I. Product Description

In the world of plastic extrusion, hot-melt tube blanks are like freshly made noodles—soft and prone to deformation. How do you make them “calm down” instantly and keep a perfect shape? The answer is this Stainless Steel Vacuum Water Cooling Tank. Acting like a “cool” fitness coach, it guides hot-melt PTFE, PETG, and PLA pipes and straws into a vacuum “pool,” where enveloping water mist rapidly sets their shape. Each pipe achieves “model-grade” dimensional accuracy and a mirror-like finish, seamlessly connecting to the next process—efficient, worry-free, and zero rework.

II. Product Advantages

1. Rapid cooling: 360° annular water curtain plus dense spray increase heat exchange efficiency by 40%. At the same line speed, tank length can be reduced by 25%, saving floor space.

2. Vacuum stabilization: Closed-loop micro negative pressure control with vacuum fluctuation ≤ 0.002 MPa achieves “zero-gravity” uniform shrinkage; ovality ≤ 0.15 mm.

3. All-stainless “skeleton”: SUS304 tank liner with 316L wetted parts resists chloride corrosion, providing ≥ 10 years of service life and eliminating rust contamination.

4. One-touch size change: Quick-release sizing sleeves and hinged viewing windows enable spec changeover in 5 minutes—ideal for small, multi-spec orders with zero waiting.

5. Smart energy saving: VFD pump and real-time temperature control save ≈ 3000 kWh annually; filtered recirculation reduces water consumption by 65%.

6. Quiet and safe: Double-layer insulated housing and low-noise centrifugal fans keep on-site noise ≤ 72 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: Warm, gentle cooling up front to prevent whitening; fast cooling at the rear to lock dimensions. Temperature gradients can be set by dragging on the touchscreen.

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

• Quick-release filter basket: 200-mesh stainless screen; remove and clean in 30 seconds, blocking impurity backflow and preventing nozzle clogging.

• Multi-material compatibility: PTFE (high-temp resistant), PETG (high transparency), PLA (biodegradable)—all in one machine. Switching formulations 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 length 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: Six 2 m standard sections can be stacked into a 20GP container, saving 30% on freight.

• Included “tool kit”: 5 spare nozzles, 10 seal sets, and a 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 run open water tanks—ovality was always unstable. After switching to this vacuum spray tank, ovality dropped from 0.4 mm to 0.15 mm. On-site customer acceptance passed at the first attempt, and rework fell to zero!”
— Mr. Li, Biodegradable Straw Plant, Dongguan

“Medical PTFE catheters demand strict cleanliness. The stainless liner plus quick-release filter design is very user-friendly. Weekly checks take 10 minutes, and the GMP auditor gave a perfect score.”
— Mr. Wang, Quality Manager, Medical Device Company, Wuxi, Jiangsu

“The equipment shipped to Mexico by sea for 40 days; the crate arrived intact. We connected water and power and started production. With the English HMI, our technician learned it in 15 minutes. After-sales required = 0—truly worry-free!”
— Carlos, Extrusion Equipment Distributor, South America

In one sentence: If you want PTFE, PETG, and PLA pipes and straws to form with stability, precision, and a brilliant finish right after extrusion, this Stainless Steel Vacuum Water Cooling Tank is the “anchor” of your production line.
