China Precision Medical Tube Extrusion Line Manufacturer, 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

Screw & Driving System

Optimum design Screw and driving system, with excellent extrusion and plasticization effect.

S136 Mould Steel

Core rods and die are made of S136 mould steel material, which ensures the inner flow surface glossiness and anti-corrosion. Structure of mold adopts "high pressure volumetric type", which can provide stable and high-speed extrusion for the tube material with tiny fluctuation.

Weak Vacuum Control

With the new "accurate control of weak vacuum" technology: vacuum and water system are controlled separately. In this way, we can coordinate the multilevel water balance control system with vacuum system, ensuring stable vacuum degree, cooling water level and water flowing.

LaserMike Measurement

Adopt LaserMike bi-direction high speed diameter measurement system for measuring diameter on line, measuring precision can reach ±0.001MM.

Stable Puller Driving

Puller adopt imported multilayer composite wearable strap (in accordance with medical sanitary requirements), with high level precision roller, SERVO motor driving offer high stability pulling.

Servo & PLC Control Cutter

Cutter equips with low inertia aluminum alloy rotating knife arm structure, driven and controlled by Servo system, which offers high speed and high accuracy cutting action. With PLC programmable control and human-computer interface, cutter can realize continuous cutting, timing cutting, length counting cutting etc. Cutting length can be freely set, automatic counting.
