10 Mesh 0.50MM Height 200 MM Stainless Steel Wire Mesh Wire Filter Tube For Filter

we specialize in woven wire mesh. One of our focuses is on customized filtration products. As you can imagine, “customized filters” is such a wide category.

The problem is that we have made filtration products for such a wide range of industries like oil and gas, food and beverage, pharmaceutical and medical and so many more.

So, although a product group like this lets us use our engineering expertise and our wire mesh capabilities, even we struggle to imagine all the possibilities.

We don’t have a lot of chances in this product line to talk about a standardized product except in the plastics industry. 

One of our most commonly made “customized filters” is an extruder screen. Sometimes these filters are also called screen packs, both mean the same thing.

Extruder screens are a necessity for any extruder of polymer or plastic. We are going to explore all things extruder screens in this article, from definitions to pricing to how they are made

The diameter is up for your request.

A polymer material needs to be formed into the desired shape. This is true whether it’s being used to produce bags, bottles, flat-screen TVs, clothing, or automotive components.

The material generally starts in pellet form. Those small pieces need to be run through some sort of manufacturing operation or they need to be extruded into a desired state.

The material needs to be processed through melt and filtration operations to be sure the material is clean and pure. This is where a melting system with extrusion screens comes in.

Extruder screens are either single-layer or multi-layer wire filtration systems that are welded together and made into specific shapes and sizes.

The melted material is forced through a wire mesh screen in order to remove any contaminants before continuing on to the next process.

Different layer configurations and micron ratings (mesh opening sizes) can be used depending on the level of decontamination required, pressure requirements, or characteristics of the material being filtered.

These screens are changed out frequently during a filtration process, and typically are not able to be cleaned or reused.

How is an Extruder Screen made?

Extruder screens are manufactured to lots of different specs. The mesh that makes up the screen will be the exact opening size for your process and the size and shape will be dictated by your machines.

Here is how an extruder screen is made:

- Wire mesh specifications with an appropriate micron rating are chosen
- Materials are layered and joined together in a spot welding operation
- Spot welded material continues on to a punching operation utilizing compound tooling
- The resulting Extruder Screens are separated from skeleton/waste material
- Finished Extruder Screens are cleaned
- Clean Extruder Screens are shrink-wrapped in preparation for shipping
