Custom Precision Medical Tube Extrusion Line Manufacturers, Factory

Medical tube extrusion line is used for producing various kinds of specification medical catheter like angiography catheter, multi-lumen tubes, hemodialysis tube, infusion tube, urethral catheter, central venous catheter, epidural  anesthesia tube, capillary tube, stomach tube, porous tube etc. Cover almost all kinds of polymer, including the largest amount of soft PVC. The particularity of medical application requires extrusion equipment to have the basic characteristics of “Precise size control and high efficiency". Medical tube extrusion line is one of product of “SXG” series precision tube extrusion line, which is the core machinery product of BAOD EXTRUSION. By virtue of ”accurate control of weak vacuum calibration” and ”high pressure volumetric extrusion” forming technology, BAOD’s medical tube extrusion line features with incredible extrusion speed (Max 180m/min), unusual extrusion stability and high control accuracy of tube size (CPK value≥1.67).

Product Description

Optimum Design Screw & Driving System: Engineered with an optimum design screw and driving system, ensuring superior extrusion and plasticization performance.

High-Precision Die & Core Rods: Built with S136 mould steel for inner flow glossiness and corrosion resistance. The proprietary "high pressure volumetric type" structure guarantees stable and high-speed tube extrusion with minimal fluctuation.

Weak Vacuum Accurate Control: Employs independent vacuum and water system controls combined with multilevel water balancing to stabilize vacuum degree, cooling liquid levels, and dynamic flow.

Online Laser Measurement: Integrated LaserMike bi-direction high-speed diameter measurement monitors dimensions on line, reaching a precision tolerance of ±0.001MM.

Medical-Grade Puller Unit: Features imported multilayer composite wearable belts matching medical sanitary criteria, paired with precision rollers and SERVO motor drives for high stability pulling.

Servo Cutting & Automation: Low inertia aluminum alloy rotary knife arm powered by a Servo system. Controlled via Japan Mitsubishi PLC and SIEMENS HMI for continuous, timed, or length counting cuts with automatic counting.

Frequently Asked Questions
Q1: What materials are used for the extrusion dies and core rods?

The core rods and dies are made of premium S136 mould steel, which provides high glossiness along the inner flow surface and ensures strong anti-corrosion protection.

Q2: How is tubing dimension precision monitored during manufacturing?

The line adopts a LaserMike bi-direction high-speed diameter measurement unit that monitors outer dimensions in real time, capable of reaching an accuracy of ±0.001MM.

Q3: How does the vacuum and cooling system maintain stability?

It features a weak vacuum accurate control design where the vacuum and water systems are regulated independently, coordinating multilevel water balancing with vacuum stability.

Q4: Are the puller components compliant with cleanroom environments?

Yes, the puller utilizes imported multilayer composite wearable belts designed specifically to meet stringent medical sanitary requirements.

Q5: What control systems are implemented for the cutting mechanism?

The cutter is driven by a Servo system and managed by a Japan Mitsubishi PLC with a SIEMENS touchscreen interface, supporting continuous cutting, timing cuts, and length counting modes.
