What are the machining processes for Catheter Mold and Mandrels?

The following are 5 methods to produce catheter mold(tip forming dies) and mandrels:

  • CNC machine tool machining: CNC machine tools are a kind of automated machining equipment, which can control the movement trajectory of the tool and the machining parameters through pre-programmed instructions. For the machining of cathetermolds and mandrels, commonly used CNC machine tools include CNC lathes, CNC milling machines, CNC grinding machines, etc.. CNC machine tool machining can realize high precision and complex shape machining needs.
  • Electrical Discharge Machining (EDM): EDM utilizes the principle of electric spark discharge to form tiny discharge pits on the surface of the workpiece to achieve the machining goal. For the machining of cathetermolds and mandrels, EDM can be used to create complex internal structures, tiny holes and angles. It can be machined on hard materials with high accuracy and surface quality.
  • Precision Grinding: Precision grinding is a high precision machining method that removes material from the surface of a workpiece by using a grinding stone or grinding tool to achieve precise control of the geometry. For the machining of tip molds andmandrels, precision grinding can be used to achieve the high accuracy and finish required.
  • Wire EDM (WEDM): Wire EDM is a method of cutting on a workpiece by means of electric spark discharge utilizing a metal wire as an electrode. For the processing of tip molds and core pins, WEDM can achieve complex contours and internal structures, and is particularly suitable for high material hardness.
  • Laser Processing: Laser processing uses a high-energy laser to process the surface of the workpiece, melting, evaporating or vaporizing the material through the heat of the beam to achieve cutting, punching, engraving and other processing operations. For the machining of cathetermolds and mandrels, laser machining allows for high-precision, non-contact and contactless machining processes.

These processing methods can be combined and applied according to specific needs and material selection. In the actual processing, it is usually necessary to combine process experience and expertise to select appropriate processing methods and parameters to ensure the processing quality and precision of catheter molds and mandrels.
