Unit characteristics
The main features of precision medical catheter are: small size, complex shape, high precision, high health index and high biochemical stability. The diameter of the catheter is generally 0.5 mm to several millimeters, the allowable diameter deviation is generally less than 5%. The successful development of our high-speed precision extrusion equipment, provide advanced and reliable production equipment for the production of high-speed precision medical catheter.
Precision medical catheter production process: according to the size and material of the catheter, set the reasonable process parameters, including raw material formula, extrusion temperature, screw speed, etc.. The multilayer composite pipe using a coextrusion or two co extrusion process. The post processing of the pipe is determined according to the requirements of the product.   
3 to ensure the uniformity of tube geometric accuracy and intrinsic performance, in the production unit we use the following key technologies and equipment:
(1) precision drive system using
(2) the adoption of voltage stabilizing system
(3) application system of precise meter pipe
(4) using CAE software, the scientific design of precise medical catheter mold production
Can be realized on the statistical process control precision control system application
Use: mainly used in the production of oxygen tube, blood transfusion tube, indwelling catheter, drainage tube, central venous catheter, endotracheal intubation, anesthesia tube, catheter, capillary, perforated pipe and other kinds of sophisticated medical catheter; the raw materials are PVC, PE, PP, PA, ABS and other medical grade plastic
