A PU tube extrusion line is a complete production system for making flexible polyurethane tubing used in pneumatic control, automation equipment and industrial air transfer. In this page, PU tube, TPU tube, polyurethane tube, PU pneumatic tube and PU air tube refer to the same buyer intent: equipment for producing flexible small-diameter tubing, not finished tubing supply.
Jinxin supplies the configured extrusion line, not finished PU tubing, not a tubing trading service and not only a standalone extruder.

Applications
What This Line Produces
PU / TPU pneumatic air tubing samples for line configuration review
PU Pneumatic Tube
PU pneumatic tube is used for air lines in automation equipment, pneumatic cylinders, factory tooling, compressor systems and control circuits. The extrusion line is configured for stable OD, smooth surface, flexible bending and consistent winding or cutting.
TPU Tube
TPU tube is often described by suppliers as polyurethane tube or TPU pipe. It uses a thermoplastic polyurethane material window and usually needs controlled drying, stable melt temperature, careful cooling and low-deformation haul-off. Jinxin can configure one PU / TPU line for the material grade and tube format confirmed by the buyer.
PU Air Tube and Polyurethane Tube
PU air tube and polyurethane tube are important search variants for the same equipment intent. The line can be built for transparent, colored or marked tubing when the material, color and surface requirement are confirmed before quotation.
PU Air Hose
Some buyers and suppliers use the phrase PU air hose production line for flexible pneumatic tubing. On this page, "PU air hose" means non-braided flexible air tube made by extrusion. Braided, reinforced or spiral hose projects need separate confirmation because they may require additional reinforcement or coiling equipment.
Key Processing Points for PU and TPU
PU and TPU are flexible polyurethane materials, and their extrusion behavior is different from rigid pipe materials. A stable line should be configured around the compound behavior, not only around machine size.
Moisture and Bubbles
What to watch
Some TPU / PU grades are sensitive to moisture. Residual moisture can create bubbles, surface defects or unstable extrusion.
Configuration response
For moisture-sensitive projects, drying and stable material handling should be reviewed before confirming the line.
Temperature Stability
What to watch
PU / TPU tube extrusion needs steady melt temperature and controlled shear.
Configuration response
Overheating, unstable screw speed or a poorly matched die can create die lines, surface roughness or unstable tube dimensions.
Surface Marks and Drag
What to watch
Flexible TPU can show drag marks when downstream contact is too aggressive.
Configuration response
Calibration surface, water cooling, haul-off contact and guide alignment should be matched to tube hardness and surface requirement.
OD Control and Shrinkage
What to watch
Dimensional stability depends on die matching, cooling consistency and haul-off synchronization.
Configuration response
For tighter OD control or continuous production records, online laser diameter measurement can be added as an optional configuration.
Cutting vs Winding Tension
What to watch
Soft flexible tubing can deform if downstream tension is too high.
Configuration response
For coiled PU air tube, winding tension and reel handling matter as much as extrusion stability. For cut tube, cutter speed and tube support must be matched to line speed and hardness.
Online laser diameter measurement is optional. It can be added when the buyer needs continuous OD monitoring, tighter QC records or higher automation.
PU / TPU Tube Extrusion Process
01
Material drying and feeding
PU / TPU grades are reviewed for moisture sensitivity. Drying can be configured when the compound needs it to reduce bubbles, splay marks and unstable surface.
02
Single screw extrusion
The screw, barrel temperature profile and drive control are selected for gentle plasticizing and stable melt delivery.
03
Tube die forming
The die and core are matched to OD, ID and wall thickness. Each confirmed tube size normally needs its own tooling set.
04
Calibration and cooling
The tube enters the calibration and cooling section to stabilize roundness, OD and surface finish.
05
Haul-off
The pulling unit synchronizes with extrusion speed while reducing deformation on flexible tube.
06
Cutting or winding
The line can be configured for fixed-length cutting, single winding or dual-position winding depending on the buyer's packaging and downstream process.
07
Optional online measurement
Laser diameter measurement can be added when continuous OD monitoring or tighter QC records are required.
Process flow: PU / TPU granules -> drying and feeding -> single screw extrusion -> tube die -> calibration and cooling -> haul-off -> cutting or winding -> verified tube output

FAQ
FAQ About PU / TPU Tube Extrusion Lines
01What is a PU tube extrusion line?
A PU tube extrusion line is a complete production line for turning PU or TPU granules into flexible polyurethane tubing. It normally includes single screw extrusion, tube die tooling, calibration and cooling, synchronized haul-off, cutting or winding and electrical control. Jinxin configures the line around the buyer's tube sample, material grade and production target.
02Can the same line produce TPU tube?
Yes. PU and TPU can be reviewed together for this type of pneumatic tubing project. The actual setup still depends on the TPU grade, hardness, moisture behavior, tube OD / ID, wall thickness and surface requirement. Jinxin confirms the screw, die, cooling and haul-off configuration after reviewing the material and tube target.
03What tube diameter range can this line make?
The actual range is confirmed by sample or drawing. Competitor SERP references often show small pneumatic tube ranges around 3-16mm or 4-16mm, but Jinxin does not publish that as a fixed limit here. Send OD, ID, wall thickness and material grade so Jinxin can confirm the feasible tooling and line configuration.
04Is online laser diameter measurement standard?
No. Online laser diameter measurement is optional. It can be added when the buyer needs continuous OD monitoring, tighter QC records, higher automation or process traceability. Standard OD control depends on matched die tooling, calibration, stable cooling, synchronized haul-off and factory test-run verification.
05Should I choose cutting or winding for PU pneumatic tube?
Choose winding when the finished product is sold or used as coiled air tube. Choose cutting when the tube is assembled into fixed-length parts. Flexible PU / TPU tubing can deform if downstream tension is too high, so the cutter, winder and haul-off should be selected together instead of treated as separate machines.
06Is this page for PU hose or finished polyurethane tubing?
This page is for PU / TPU tube extrusion equipment. Some buyers call the product PU air hose, especially in pneumatic applications, but Jinxin is not offering finished hose or finished polyurethane tubing here. If the target product is braided, reinforced or spiral hose, the structure must be reviewed separately.
07Can this line make medical tube or catheter tube?
Medical tube and catheter tube are not default coverage for this page. They can involve special materials, clean production requirements, validation and compliance responsibilities outside a general pneumatic PU tube line. This page focuses on industrial PU / TPU pneumatic air tubing.
08What information is needed for quotation?
Send a tube sample, drawing or short video when available. At minimum, Jinxin needs the material, tube OD / ID / wall thickness and whether the output should be cut or wound. Hardness, color, tolerance and output target can be added if already known.
Send your PU / TPU tube size and material information, and Jinxin will prepare a custom turnkey line configuration for review.
