These granules are precisely blended with stabilizers, colorants, and other proprietary additives to achieve the desired tube characteristics, such as UV resistance or specific colors for coding. Consistency in material composition is paramount to ensure uniform product performance across batches.

The blended material is then fed into a high-precision extruder, where it is heated to a molten state and forced through a die to form the continuous tube profile. Critical parameters such as temperature profiles, extrusion speed, and cooling rates are precisely managed to control dimensional accuracy, wall thickness uniformity, and the overall structural integrity of the tube. Post-extrusion, the tube undergoes immediate cooling in a controlled environment, often involving water baths, to solidify its form. In-line laser gauges and ultrasonic sensors continuously monitor the outer diameter, inner diameter, and wall thickness, ensuring strict adherence to specifications. This real-time feedback loop allows for immediate adjustments, minimizing deviations and ensuring a consistent, high-quality product ready for cutting and packaging.

Essential Technical Parameters and Performance Metrics for PU Tubing

Understanding the technical specifications of pu pneumatic hose is vital for selecting the appropriate product for any given application. Key parameters directly influence the tube's suitability for specific pressure ranges, environmental conditions, and mechanical stresses.
