Blesson | Medical Endotracheal Tube Extrusion Line | TPU & PVC

一. Product Overview of the Blesson Endotracheal Tube Extrusion Production Line

The Blesson endotracheal tube extrusion production line is specifically designed for the extrusion molding of medical endotracheal tube tubing. It is intended for medical device manufacturers and is compatible with medical-grade raw materials such as medical-grade TPU and phthalate-free PVC. Depending on different clinical requirements and product structures, Blesson can configure equipment for customers to produce standard adult and pediatric endotracheal tubes, wire-reinforced endotracheal tubes, and double-lumen bronchial tubes. The tubing produced on the Blesson endotracheal tube extrusion production line is primarily used in surgical anesthesia ventilation, ICU respiratory support, emergency airway establishment, and other scenarios, and is subject to high requirements for dimensional accuracy, cleanliness, flexibility, strength, and batch-to-batch consistency.

The production line is designed around the standardized and volume manufacturing requirements of medical tubing, with consideration given to material compatibility, forming stability, and clean production requirements. Through functions such as precision extrusion, vacuum sizing, inline diameter measurement, radiopaque line co-extrusion, and data traceability, Blesson equipment helps customers establish a stable, controllable, and traceable production process for endotracheal tube tubing, meeting the quality management and volume manufacturing needs of medical device manufacturers.

二. Description of the Blesson Endotracheal Tube Extrusion Production Line

（1）Overview of the Blesson Endotracheal Tube Extrusion Production Line

The Blesson endotracheal tube extrusion production line is an extrusion molding system for medical endotracheal tube tubing, covering key stages such as plasticizing extrusion, synchronous control, vacuum sizing, inline inspection, radiopaque line forming, and production data retention. The complete line is compatible with material systems such as medical-grade TPU and phthalate-free PVC and can be configured and adjusted according to different product requirements, including standard tubes, wire-reinforced tubes, and double-lumen bronchial tubes.

The production line emphasizes cleanliness control and process stability and is suitable for use in standardized medical device manufacturing environments. Through coordinated control of extrusion, sizing, diameter measurement, and haul-off, the tubing maintains relatively stable outer diameter, wall thickness, and roundness during continuous production, providing a qualified tubing basis for subsequent assembly, welding, printing, packaging, and other processes.

（2）Core Configurations of the Blesson Endotracheal Tube Extrusion Production Line

1.Precision Plasticizing Screw and Clean Direct-Drive

Blesson provides customers with precision plasticizing screws, which help achieve uniform plasticization of medical raw materials and reduce the impact of localized overheating or uneven plasticization on tubing performance. The Blesson drive system adopts a clean direct-drive structure, reducing contamination and speed fluctuations that may be caused by conventional transmission components, thereby improving operational stability and cleanliness.

2.Closed-Loop Servo Synchronized Speed Control

Key processes of the Blesson endotracheal tube extrusion production line, such as extrusion and haul-off, adopt closed-loop servo synchronized control so that line speeds at each stage remain coordinated and matched. This configuration helps stabilize tubing dimensions, reduce issues such as diameter deviation and uneven wall thickness caused by speed fluctuations, and improve the stability of continuous production.

3.Vacuum Stainless Steel Water Bath Sizing

After extrusion, the tubing enters a vacuum stainless steel water bath for sizing. Vacuum sizing helps the tubing cool rapidly and form round, and improves the surface quality of the inner and outer walls, making tubing dimensions more stable and meeting the requirements of medical endotracheal tubes for tube roundness and surface cleanliness.

4.Inline Diameter Measurement for Real-Time Dimensional Correction

The Blesson endotracheal tube extrusion production line is equipped with an inline diameter measurement system that can monitor the outer diameter of extruded tubing in real time and feed the measurement results back to the control system for real-time dimensional correction. This function helps reduce the scrap rate and improve dimensional consistency and batch stability.

5.Integrated Radiopaque Line Extrusion

Tubing with a radiopaque line can be extruded in an integrated manner, so that the radiopaque line is simultaneously integrated during tubing formation, reducing subsequent processing steps. This method helps maintain a stable position of the radiopaque line, improve overall tubing consistency and production efficiency, and meet the radiopacity requirements of medical endotracheal tubes.

6.Full Retention and Traceability of Production Data

The Blesson endotracheal tube extrusion production line can record, store, and trace key production data, facilitating batch management, quality analysis, and process review for customers. Combined with clean production control, the produced tubing meets cleanliness standards and can satisfy the requirements of standardized volume manufacturing and quality traceability in the medical device industry.

（3）Overall Advantages of the Blesson Endotracheal Tube Extrusion Production Line

The overall advantages of this production line are mainly reflected in the following aspects:
