Medical Catheter Tip Molding

Medical catheter tip molding refers to processing the tip of the catheter to give it a specific shape and function. The purpose of medical catheter tip molding is to meet different clinical needs and application scenarios.

Common medical catheter tip-forming methods include:

1. Shear forming: Forming is achieved by shearing, cutting, or slicing at the tip of the catheter. This method is often used for some simple catheter tips, such as infusion catheters.

2. Thermoplastic molding: Taking advantage of the properties of thermoplastic materials, the catheter tip is heated at high temperatures to soften it, and then molded or other tools are used to shape it into a specific shape. This method is often used for catheter tips that require special shapes or angles, such as urinary catheters, stent catheters, etc.

3. Hot Needle Forming: Use a hot needle (soldering iron or electric heating needle) to heat the tip of the catheter to soften and shape it in a localized area. This method is often used for catheter tips that require subtle shape adjustment, such as vascular catheters.

4. Injection molding: The thermoplastic material is injected into the mold through the injection molding process, and a catheter tip of a specific shape is obtained after cooling and solidification. This method is often used for catheter tips with complex shapes or requiring special functions, such as cardiac catheters, catheter valves, etc.
