Process for Catheter Tip Molding Technology

Process for Catheter Tip Molding Technology basic steps typically include heating, molding, cooling, and demolding.

  • Heating and Molding
    During the heating stage, the catheter tube is heated to its plasticizing temperature. the catheter tube softens and is ready for molding.CatheterMelt use RF technology to keep heat uniformly to avoid localized overheating or underheating of the pipe.
  • Cooling
    After molding, the catheter needs to be cooled to cure its shape. Cooling is usually done in the mold to ensure that the accuracy of the molding is maintained. This process must be properly controlled to prevent shrinkage or distortion of the material. Cathetermelt tipping machine use air cooling.
  • Demolding
    Once the catheter tube has cooled and cured, it is removed from the mold.
  • Precautions
    The following factors must be carefully controlled throughout the thermoforming process:
  • Temperature: The heating temperature must be precisely controlled to ensure that the tube is heated uniformly over the entire heating zone to avoid localized overheating or underheating.
  • Time: The heating and cooling times have a direct impact on the quality of the final product. Too little time may result in insufficient softening of the material, while too much time may result in degradation of material properties.
  • Pressure: In some forming processes, pressure may need to be applied to aid in shaping, especially in blow molding. 
  • Material Properties: Different materials have different forming properties, such as thermal stability, elasticity, hardness, etc. Heating and cooling parameters must be adjusted according to the material properties.
  • Mold design: Molds must be designed to withstand high temperatures while accurately forming the desired shape of the catheter tip.
