High precision and stability of melt pumps in medical catheter extrusion

Precision medical catheter extruder melt pump in the field of medical tube manufacturing has significant advantages characterized by the following aspects:

High precision metering

Precision medical catheter extrusion melt pump can accurately control the flow of polymer melt. In the medical catheter extrusion process, the catheter size precision requirements are extremely high, for example, some catheters used for vascular intervention, its inner diameter may be between zero point a few millimeters to a few millimeters, the wall thickness also has a strict standard. Melt pumps can precisely deliver the melt to the extruder head according to a preset flow value, ensuring uniform catheter dimensions. This high-precision metering capability enables the production of medical catheters to meet stringent dimensional requirements, improving product qualification rates and quality stability.

Stabilized pressure output

Medical catheters are made of various materials, including polyurethane and silicone, which are more sensitive to pressure during extrusion. The melt pump enables the melt to be extruded under stable pressure, like a pressure stabilizing valve, preventing pressure fluctuations from causing quality problems such as uneven surface, uneven thickness or internal structural defects in the catheter. The stabilized pressure output ensures the stability and quality consistency of medical catheters during the extrusion process.

Optimize production efficiency

The melt pump helps optimize the operation of the entire medical catheter extrusion line. It works in concert with other equipment such as extruders and dies to make the entire production process smoother. By accurately metering and steadily delivering the melt, the scrap rate during the production process is reduced, production efficiency is improved, and production costs are reduced. In addition, the stable output of the melt pump also enables the extrusion process to run stably at a higher speed, further increasing the production speed and meeting the growing market demand for medical catheters.

adaptable

Melt pumps can be adapted to the extrusion needs of different materials. Whether it is thermoplastic elastomer (TPE), polyvinyl chloride (PVC) or other medical polymer materials, melt pumps can be effective melt transportation. Different materials may be used in the production of medical catheters for different applications, such as infusion tubes, urinary catheters and breathing tubes. Melt pumps can be adjusted accordingly to the different viscosity, fluidity and other characteristics of the materials, ensuring versatility in the extrusion production of medical catheters made of different materials.

very small pressure flow pulsation and linear output

Precision medical catheter extrusion melt pump has a very small pressure flow pulsation, can realize the flow of linear output. This feature makes the melt pump in the precision extrusion system outstanding performance, can further ensure the medical catheter extrusion accuracy and quality stability.
