Why should a melt pump be installed in a medical catheter precision extrusion line?

For metering feeding, melt pump, vacuum shaping cooling, online measurement and haul-off cutting are all important parts of precision extrusion, which are related to the quality and output of products. Such as melt gear pump, some manufacturers are reluctant to install, thinking that it has little effect on the quality.

melt pump for extrusion

Through practice, it has been proved that for high-precision extrusion production melt pump is to be installed, and to use high-precision melt pump, it is true that the extruder screw can play a role in the melt pump, mixing, extrusion, pumping, etc., but the high-precision melt pump for extrusion can improve the stability of the melt pressure, improve the pressure of the head to increase the output of the extruder, to ensure the quality of the conduit. Thus, the extruder screw can be allowed to focus on mixing and melting.
