The present invention provides a method and apparatus for producing a crosslinked foamed article. Such a method comprises the steps of: (a) uniformly mixing at least one crosslinkable resin, at least one crosslinking agent, at least one foaming agent, and some additives into a resin composition; (b) extruding the resin composition through a die into an extrudate of a predetermined shape; and (c) heating the extrudate to a temperature sufficient to cause crosslinking and foaming of the crosslinkable resin while being driven by a driving device to move in the extruding direction, thereby obtaining a crosslinked foamed article. By means of the present invention, the resin extrudate can progress smoothly through the heater or the mold.

A tipping device and processing for medical catheters, the device including a pneumatic mechanism, two fixtures controlled by the pneumatic mechanism to hold two opposite ends of the catheter, a nozzle controlled to heat or cool down the catheter, and hydraulic cylinder controlled to pull the catheter during the heating. When the front part of the catheter is heated and pulled, the outer diameter of the front part of the catheter is gradually reduced toward the middle, then the catheter is cooled down and removed from the device and then cut into a tapered tip.
