The double cylinder screen changer consists of a main body and two core shafts, each symmetrically equipped with one or more filtering channels. The filtering channels on these two core shafts can be in the working position at the same time, and also allow the filtering channels on one core shaft to be in the working position, while the filtering channels on the other core shaft are in the non working position, to achieve non-stop screen changing.

1. Subject

A shell that supports a spindle or slide to form a flow channel.

2. Mandrel

A cylindrical structural component that supports the filter screen and porous plate and can be moved within the main body during screen replacement.

3. Porous plate

A plate like structural component that supports the filter screen.

4. Filter screen

Made of metal wire mesh with different mesh sizes, its function is to filter the molten material flow and increase the resistance of the material flow, thereby filtering out impurities and improving the mixing or plasticizing effect. Its shape is in the form of a strip, tube, or disc.

We believe that any type of plastic product has a suitable polymer screen changer, and each type of plastic product has different production processes and raw materials, and the requirements for the screen changer are also different. Therefore, we have carried out one-on-one targeted research and design, and developed various specialized screen changers, such as XPS extrusion board dedicated non-stop mesh changers; Special non-stop screen changer for film blowing; Special non-stop screen changer for wire drawing machine, etc.
