Application and characteristics of pearl cotton foaming machine screen changer

The screen changer of pearl cotton foaming machine is usually installed in the extrusion system, between the screw extruder and the die head. In the production process of pearl cotton, plastic particles (mainly polyethylene and other raw materials) are heated, melted, and plasticized in a screw extruder. However, the raw materials may contain impurities such as incompletely melted plastic pellets, dust, foreign objects, etc. The main function of the screen changer is to filter the plastic melt before it enters the mold head, ensuring the purity of the melt entering the mold head, thereby improving the quality of pearl cotton products.

For example, in the production of high-quality pearl cotton packaging materials, pure melt can make the foam holes of pearl cotton more uniform and the surface smoother. If there is no screen changer to filter impurities, these impurities may block the spray holes of the mold head, causing uneven foaming of pearl cotton, resulting in local density being too high or too low, affecting its buffering performance and appearance quality.

Characteristics of pearl cotton foaming machine screen changer

1、 Structural characteristics

a. Overall design: The screen changer of pearl cotton foaming machine usually adopts an overall structural design to ensure the stability and durability of the structure.
