1. The key of plasticizing system includes PFA extruder screw and barrel.

In order to consider various types of production and processing requirements, usually the screw and barrel design scheme for the combination of building blocks. According to the role of each part, the screw can be divided into feeding section. Plasticizing section. Mixing section. Exhaust section and extrusion unit. This kind of component has different role in the whole process of extrusion, its structure is not the same, the relative screw component geometry parameters are not the same. Therefore, how to determine the geometric parameters of threaded components has become the key to the design of plasticizing system.

2. Diameter ratio (that is, the ratio between the center distance of two screws and the radius of the screws).

There is a certain relationship between the number of PFA screw threads and the top Angle of the thread, can not be arbitrarily designed, otherwise there will be interference between the two screws. In order to solve this problem, Shenzhen Dankai obtained the theoretical end curve of the screw according to the trajectory of the screw, using the three-dimensional solid modeling effect of large-scale computer aided design (CAD) software, so as to design the best PFA screw.

 

3. In addition, combined with the project practice, with the help of the computer, control the gap of the screw barrel of the PFA tube extruder, so that the material has no dead Angle in the movement of the screw, that is to ensure that the screw has a strong self-cleaning ability, which can effectively prevent the PFA material from staying in the machine for a long time and degradation, undoubtedly producing high-grade products.

For more information about PFA tube extruder, please continue to pay attention to Shenzhen Dankai Technology Co., LTD.
