How Guidewire Tip Forming Machine Work?

Guidewire tip forming machine is a device specifically designed to create precise round tips at the end of guidewires. These tips are usually made of thermoplastic material, and they minimize damage to the blood vessels when the guidewire is inserted into the body. Below is a comprehensive explanation of how the guidewire tip molding machine works:

  • Preparation of the guidewire

Before the molding process begins, the guidewire needs to be cleaned and sterilized to remove any contaminants that may affect the quality of the molding.

  • Heating

One end of the guidewire is heated to a specific temperature so that it reaches a state suitable for adhesion of the plastic material. This is usually accomplished by an integrated heating unit that precisely controls the temperature.

  • Shaping

– The heated tip of the guidewire is placed into a mold that has an inner cavity with the desired tip shape.

– A thermoplastic material, such as polytetrafluoroethylene (PTFE), polyurethane or polyether block amide (PEBAX), is then fed into the mold and covered with the tip of the thermal conductor.

  • Molding

– In the mold, the plastic material melts due to the high temperature and is molded into the desired tip shape under the appropriate pressure.

– Once the plastic material has filled the mold and covered the tip of the guide wire, it begins the cooling and curing process.

  • Cooling and Curing

– Cooling is a critical step in the molding process that ensures that the plastic material adheres firmly to the metal guide wire and maintains the precise tip shape during curing.

  • Stripping

– Once the plastic is fully cured, the molded wire can be removed from the mold.

  • Quality Inspection

– Each molded guidewire tip is subjected to quality inspection to ensure that the tip shape, dimensions, and integrity of the plastic overlay meet strict medical standards.

– Inspection may include visual inspection, dimensional measurements, and possibly functional testing.

  • Post-processing

– In some cases, the molded guidewire tip may require further processing, such as the application of special coatings, to improve its performance or reduce patient discomfort.

Guidewire tip molding machines ensure the quality and consistency of guidewire tips by precisely controlling the heating, plastic material supply, molding pressure, and cooling processes. These devices are essential to ensure that guidewires used in interventional medicine procedures are safe and effective.
