二. Overview and Core Advantages of the Blesson High-Speed Precision Infusion Tubing Extrusion Production Line

（1）Overview of the Blesson High-Speed Precision Infusion Tubing Extrusion Production Line

The Blesson production line is an integrated, fully automatic precision extrusion line. It incorporates core process modules such as material plasticization and extrusion, tubing cooling and sizing, inline dimensional inspection, precision haul-off and conveying, and digital production control and management. Its overall design complies with the requirements of medical cleanroom production environments and enables continuous, automated production from raw material feeding to finished tubing output. While ensuring high precision, it also achieves high-speed production efficiency, making it suitable for large-scale medical tubing production.

（2）Core Configurations and Equipment Advantages of the Blesson High-Speed Precision Infusion Tubing Extrusion Production Line

1.Optimized Screw Extrusion System

Blesson equipment optimizes the screw configuration according to the characteristics of medical polymer raw materials, adopting a structural design and low-shear plasticization path suitable for medical polymers. Under high-speed extrusion conditions, it still ensures uniform melting and plasticization of raw materials, effectively reducing material degradation, gels, and color variations in the tubing.

Blesson equips customers with a multi-zone precision temperature control system to precisely control extrusion temperature, ensure a stable melt state, and lay the foundation for dimensional consistency and stable performance of the tubing.

2.High-Efficiency Cooling and Sizing System

The Blesson high-speed precision infusion tubing extrusion production line is equipped as standard with a dual-end cooling water bath configuration, which accelerates tubing sizing by extending the cooling path and effectively improves overall production efficiency.

另外, Blesson can provide an optional reciprocating serpentine cooling water bath according to customers’ site and process requirements. This configuration achieves a longer cooling travel within a more compact footprint, significantly improving cooling and sizing performance and ensuring tubing roundness and dimensional accuracy.

The main body of the water bath is made of medical-grade stainless steel, conforming to medical cleanroom production standards and meeting the requirements for long-term stable operation and ease of cleaning and maintenance.

3.Laser Closed-Loop Diameter Gauging System

The Blesson high-speed precision infusion tubing extrusion production line is equipped with an inline laser closed-loop diameter gauging system. It uses non-contact high-speed laser inspection technology to monitor key dimensional parameters such as tubing outer diameter and roundness in real time.

Measurement data are fed back to the control system in real time to automatically calibrate extrusion speed, haul-off parameters, and sizing vacuum, enabling dynamic correction of dimensional deviations. This ensures uniform and consistent tubing dimensions, with accuracy up to the micron level, meeting the stringent tolerance requirements of medical tubing.

4.Digital Full-Process Traceability Management and Control

The Blesson high-speed precision infusion tubing extrusion production line is equipped with a digital production management system that collects and stores process parameters, dimensional data, and operating status in real time throughout the production process. It supports retrieval of historical data for traceability, enabling traceable control across the entire production process. This helps enterprises comply with Good Manufacturing Practice for Medical Devices and consistently ensures that each batch of tubing meets requirements for dimensional accuracy, cleanliness, and performance.

（3） Blesson Customized Services

Blesson can provide comprehensive customized solutions based on customers’ actual production needs: it can tailor production line configurations and cooling solutions to different capacity requirements and site spaces; customize extrusion dies and screw configurations according to tubing specifications (直径, 壁厚, and single-layer/multi-layer co-extrusion structure); and offer optional downstream cutting, 收卷, inspection, and other expanded functional modules as needed. It also supports customization requirements such as special material compatibility and control system upgrades, creating dedicated medical tubing extrusion lines tailored to customers’ specific production scenarios.
