Dankai PFA pipeline extruder, through the feed throat (near the cavity tube back end opening) into the material, and contact with the screw. Rotate the screw (usually turning 120 RPM) to force the plastic bead to turn toward the heating barrel.
Due to the influence of adhesive heating, the required extrusion temperature is rarely equal to the set temperature of the cylinder. In most processes, due to the effects of sticky heating, etc., the heating profile is set to the barrel, where three or more independent PID controls control the heating zone by increasing the temperature of the barrel forward from the rear (plastic entry).
Heating is caused by pressure and friction in the inner barrel. In fact, if the PFA pipe extrudes the PFA resin fast enough, the heater can be turned off. Of course, this is only an ideal situation, and there is no way to keep the temperature in equilibrium. The equilibrium must be dynamic.
Dankai found that the above factors had a great impact on the screw, cavity, die and temperature control tests of different PFA tube extruders. The working principle is similar, but the process is slightly different. It is these differences that determine the product details of PFA management.
