The extruder screen prevents contamination in the melted mass during the extrusion process.

Screens for extrusion are primarily determined by their shape, dimensions, material, and mesh size. For screen packs, be sure to designate the screen layers in order, so we know how to stack for welding.  Common round screens have an outer diameter measurement. Oval, kidney, or irregular shapes that should be measured carefully. We invite you to send a sample of what you need, so we can help you positively identify it before ordering.  

Most extruder screens are steel. Plain steel is often sufficient. If there is more abrasion/corrosion you may use stainless steel. There are other specialty materials- ask if you have a unique application! 

The mesh size has to do with the size of the wire and of the space between them. In the extrusion world, square weave mesh can be as large as #8 and as small as #500. Dutch weaves range from a 12/64 rectangular pattern to 80/400. In either case, the smaller the number, the larger the hole size. If you aren’t sure, feel free to supply us a sample!

Optimal pressure and filtration can be built with individual screens stacked in a way that progressively restricts and allows the material flow. Ordering a welded screen pack from ECS will eliminate the human error associated with the stacking and make screen changes a snap.

We maintain one of the largest stocks of wire mesh and extruder screens in the USA. We can generally ship screens and packs in 5-7 days and often have the capacity to offer an Expedite path for critical situations. We manufacture in the USA and ship worldwide.

Yes! We manufacture custom breaker plates here in the USA. We have a large library of designs and drawings. We can use your drawing. If there is a drawing, we can receive a breaker plate and make one in the process of making the quotation. They are most often made with 17-4 PH stainless, and heat treated to H900 condition.
