Multi-Material · Universal Vacuum Sizing Water Tank

— A flash-cooling capsule that makes PVC, PE, PPR, and MPP “perfectly round”

Product Description

This isn’t a traditional “water dip tank”; it’s a flash sizing capsule that combines “vacuum + water cooling”:

• Right after the melt leaves the die, it’s “rounded and compressed” within 0.3 s in a high‑vacuum zone;

• It then enters an annular water curtain and completes ultra-fast cooling from melt to solid in 20 s;

• Full 304 stainless-steel construction—no rust, no leaks for 10 years; change materials without changing the tank.

One tank, compatible with PVC drainage, PE water supply, PPR hot water, and MPP cable ducts—a truly universal capsule for multiple plastics.

Product Advantages

1. Multi-material in one machine, 5-minute changeover
   Quick-release sizing sleeve. Switching PVC → PE → PPR → MPP only requires changing the die and sleeve. Up to 4 materials per shift—small batches made easy.

2. Four independent vacuum zones, roundness ≤0.15 mm
   Four vacuum chambers with independent pressure control. Upstream high negative pressure for sizing, downstream slight vacuum to relieve stress—Φ630 large pipes come out “as if drawn by a compass.”

3. Dual cooling: waterfall + immersion, line speed ↑30%
   Upper waterfall curtain rapidly removes surface heat; lower immersion bath uniformly extracts core heat. Thick-wall MPP pipes: speed boosted from 1.2 m to 1.6 m without deformation.

4. Half the energy, 8 dB quieter
   Permanent-magnet VFD vacuum pumps + EC centrifugal water pumps save 42% power vs. gear-pump systems. Workshop noise 65 dB—quiet enough to hear the phone ring.

5. Zero dead water, easy to clean
   5° sloped bottom + Φ75 quick-drain valve. Water change in 45 seconds—no residue, no odor; suitable for direct online production of medical-grade PVC tubing.

Core Features

• 2.5 mm 304 stainless sheet, single-piece bending: seamless, dirt-free; 1000 h salt spray with no rust spots.

• Magnetic snap-in filter basket: one-second removal, no debris recirculation; triples pump lifespan.

• Touch formula screen: 50 sets of process parameters, one-tap recall; 10-second material changeover.

• Plug-and-connect: standard Ethernet for ERP/MES; one-click dispatch from order to parameters.

• Export-grade rubberized casters: 8 swivel wheels on the tank; move the line like a suitcase.

Voices from Users

• Shandong XX Pipe (PVC drainage)
  “One machine runs 4 materials. Only swap the sizing sleeve for changeovers. Saved 2 hours per shift and 60,000 RMB in annual labor!”

• Egypt Agro Drip (PE irrigation)
  “At 45 °C desert temps, the tank ran two years with zero rust. Vacuum still at –0.07 MPa. The boss ordered two more lines on the spot.”

• Jiangsu XX Medical (PVC tubing)
  “Used in a cleanroom. Water change done in 45 seconds, microbiology passed first time. Saved 3 hours of cleaning versus our old European unit.”
