When deciding on the right filtration screen for your extruder, what element is the most fundamental? Is it the mesh count? Or maybe the material used to make it? What about the size and shape of the screen?

All four are crucial to consider when choosing extruder screens, but with so many variables to consider in the polymer extrusion process, it can be challenging to know where to begin. An excellent place to start is the mesh count used to filter your product. 

Depending on the material to be filtered, your screen should have the correct mesh weave and count to optimize filtration effectiveness, which in turn can increase output and improve product quality. Screens also need to be crafted from the right metal for your material. Made from a variety of metals, such as stainless steel, Monel, and Hastelloy, some are prone to corrosion or rust when used with certain filtered products, so be sure to know which metal is best suited for your needs. If you’re not sure what you need, ECS experts can help. 

The next step would be specifying the shape and size of your screen. A perfect fit to your extruder is critical to a quality filtration process, and there are a lot of size and shape options available for extruder screens and screen packs. If ECS doesn’t already have what you need in their vast inventory, they can design a custom die to ensure a precise and consistent fit, and reliable performance. Some of the stock options for polymer filtration include:
