Extrusion Precision Medical Inner Tubings

The precision medical inner-layer thin-walled catheter is a high-precision, high-performance medical device mainly used to guide and deliver drugs, liquids, gases, and other treatment or examination tools to specific parts of the patient's body.

In order to manufacture this thin-walled inner conduit, extrusion processing is required. Extrusion is a method of forcing molten plastic or metal into shape through a die. The steps for manufacturing precision medical inner thin-walled catheters are as follows:

1. Material selection: Choose high-quality plastic materials suitable for medical applications, such as polyethylene, polypropylene, polyurethane, etc.

2. Melting: Heating the selected plastic material to a molten state usually requires the use of a special extruder to complete this step.

3. Extrusion: Molten plastic material is extruded through a die. A die is a tool with holes of a specific shape and size used for plastic extrusion.

4. Cooling: After extrusion, the conduit is cooled so that it solidifies and maintains the desired shape.

5. Cutting and trimming: Cut the cooled conduit to the required length and perform necessary trimming to meet quality requirements.
