1. Water inlet area.
Basically what happens here is the inhalation, compression, and transportation of raw materials. If you want to have a unique commodity characteristic, you can choose additives at this stage. The resin is fed into the PFA tube extruder by the material hopper and into the screw by the feeding pipe. The screw then moves the raw material forward. The amount inhaled depends on certain factors, including screw speed and PFA resin density. It also depends on the screw channel depth and pitch.
2. Melting zone.
Once the material is in the screw, the extrusion process begins. The screw continually pushes the resin forward. When this happens, friction occurs between the material and the barrel, causing the resin to melt. Get extra heat from the heater underneath the bucket. This ensures that the resin melts completely. As the PFA resin moves forward, friction and pressure in the barrel increases.

3. Measurement area.
Once the polymer melt is complete, the broken plate with the screen is left behind by the extruder. Molten zone unmelted particles also occur here. This ensures the uniformity of the molten resin. In order to achieve plastic uniformity of PFA, the number of screens and the porosity of screens are controlled. The high pressure here causes the PFA molten polymer to be extruded into shape. In this section, there is an air pump to prevent the PFA product from collapsing.
4. Cooling area.
The PFA moves to the cooling zone and cools in it. There are two types of cooling systems you can use. There are air and water cooling systems. Depending on the type of cooling system you use, PFA products will slowly cool. This gives PFA products the perfect shape and gives them the appeal they deserve.
