PU / TPU pneumatic tube extrusion line
A custom turnkey extrusion line for producing PU and TPU pneumatic air tubing, polyurethane tube and flexible industrial air tube.
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.
Jinxin supplies the configured extrusion line, not finished PU tubing, not a tubing trading service and not only a standalone extruder.

Applications
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 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.
The line can be built for transparent, colored or marked tubing when the material, color and surface requirement are confirmed before quotation.
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.
PU / TPU pneumatic tubing is used where flexibility, bending performance and smooth air flow are more important than rigid pipe strength.
Stable OD, smooth inner path, reliable winding or cutting.
Flexible tube output, surface quality and tube roundness.
Material hardness, wall thickness and collection method.
Flexible routing and consistent tube diameter.
For projects using non-braided flexible PU air tubing.
Small-diameter tube stability and clean surface finish.
Application boundary: medical tubing, catheter tube, braided hose, reinforced hose, spiral spring tube and garden hose should not be treated as default coverage for this page. They can be reviewed as separate configurations only when the buyer confirms the product structure and Jinxin confirms the required downstream equipment.
Jinxin can test the configured line before shipment with agreed tooling and material conditions when available. Startup references such as temperature, screw speed, haul-off speed and downstream settings are recorded for handover.
Send Tube Size & MaterialOnline laser diameter measurement is optional. It can be added when the buyer needs continuous OD monitoring, tighter QC records or higher automation. It is optional, not a default claim in the base line.
PU and TPU are flexible polyurethane materials, and their extrusion behavior is different from rigid pipe materials. Before selecting machine size, confirm the compound grade, hardness and finished tube use; the common plastics used in extrusion guide explains why TPU tubing needs a different process route from rigid PVC, PE or PP products.
For a PU / TPU pneumatic tube project, material preparation, melt stability, OD / ID / wall control and collection method must be treated as one configuration. Hygroscopic grades require a verified drying route before extrusion; see resin drying in plastic extrusion for the roles of temperature, time, airflow and dew point. The confirmed tube tolerance then determines tooling, calibration, optional laser measurement and haul-off control, while the delivery format determines cutting or winding equipment.
Some TPU / PU grades are sensitive to moisture. Residual moisture can create bubbles, surface defects or unstable extrusion. For moisture-sensitive projects, drying and stable material handling should be reviewed before confirming the line.
PU / TPU tube extrusion needs steady melt temperature and controlled shear. Overheating, unstable screw speed or a poorly matched die can create die lines, surface roughness or unstable tube dimensions.
Flexible TPU can show drag marks when downstream contact is too aggressive. Calibration surface, water cooling, haul-off contact and guide alignment should be matched to tube hardness and surface requirement.
Dimensional stability depends on die matching, cooling consistency and haul-off synchronization. For tighter OD control or continuous production records, online laser diameter measurement can be added as an optional configuration.
Soft flexible tubing can deform if downstream tension is too high. 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.
Select a stage to see its details.
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.
The screw, barrel temperature profile and drive control are selected for gentle plasticizing and stable melt delivery.
The die and core are matched to OD, ID and wall thickness. Each confirmed tube size normally needs its own tooling set.
The tube enters the calibration and cooling section to stabilize roundness, OD and surface finish.
The pulling unit synchronizes with extrusion speed while reducing deformation on flexible tube.
The line can be configured for fixed-length cutting, single winding or dual-position winding depending on the buyer's packaging and downstream process.
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
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.
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.
The actual range is confirmed by sample or drawing. Send OD, ID, wall thickness and material grade so Jinxin can confirm the feasible tooling and line configuration.
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.
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.
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.
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.
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.
