An extruder screen, often referred to as a screen pack, is a woven wire filtration system that is formed to meet the needs of the customer.Extruder screens are available in both single-layer and multi-layer configurations to remove impurities from melt plastics.
Extruder-ScreenWhen choosing the size of your extruder screen, you need to consider factors such as pressure requirements, the characteristics of the material being processed, and the level of purification required.
A thin mesh count may provide the desired level of decontamination, but it may cause pressure levels to damage your device. An excessively large mesh count may allow for sufficient flow, but it can also cause contaminants to enter the final product.
Most extruder screens in the plastics industry are typically square mesh weaves in the 20-150 mesh range, made of stainless steel to avoid corrosion/contact corrosion.
