4 Essential Elements When Choosing Extruder Screens

by Gabe Lawrence

When you are running a process where a polymer or plastic is melted down before being turned into the final product, the material is going to need to pass through some extruder screens. Extruder filters are used to remove impurities and contaminants from the melted material before the base material is used to create a specific object.

When purchasing extruder screens and choosing a manufacturer to work with, you need to have a good understanding of the material you are working with. You also need to know what to look for when choosing extruder screen packs.

Element #1: Quality Welding

The first thing you need to pay attention to when looking at extruder screens is the quality of welds. Although these screens are generally small, they still go through a detailed welding process. Before ordering numerous extruder screens, order a sample, and examine the welding on the screen. Proper welding is necessary for the screen to stand-up to the filtration process and do its job.

Element #2: Material

The material for your extruder screens depends upon the material that you are melting and filtering. The extruder screen material needs not to be impacted by the material it is designed to filter. The extruder screen should not rust or break down due to the interaction between the filtered material and the screen.

Steel, stainless steel, and nickel-alloy are three of the more popular materials used for extruder screens.

Element #3: Mesh Count

Next, you need to look at the mesh count for the filters. The mesh count lets you know what size material can easily flow through the screen and what size material will be stopped by the screen. The smaller the contaminants you want to remove from the melted material, the higher the mesh count you need to purchase. For example, if you need very fine filtration, you are going to want to go with 1000 microns, not 500 microns.

Element #4: Layers

Finally, you need to determine if your filtration system needs single layer filters or multi-layer filters. Single-layer filters are most often used when the material being filtered does not have that many contaminants, such as a virgin material. Multi-layer filters are most often used when the material being filtered is not a virgin material but is instead a recycled or reground material. Multi-layer filtration systems are also used when it is vital for the end material to be as pure as possible.

When it comes to purchasing extruder screen, pay attention to the quality of the welding, the material used for the weld, the mesh count of the screen, and the number of layers the screen has. These four elements will help you pick the right screen for your filtration process.
