The extruder screen is nothing but a filter screen, punched out of a specifically woven wire mesh roll.

The extruder screen is a vital component being used in the plastic and polymer extrusion process. The screens are placed on the extrusion machine’s breaker plate to filter the contaminations and other foreign particles from the melted plastic. Extruder screens are made in a specific shape (i.e., Circular, Oval, Rectangular, and Kidney), using single or multi-layered wire mesh screens.

The specifications of wire meshes for extrusion are determined by looking at the quality of plastic raw material and contamination. Practically to extrude a certain kind of granules, the manufacturer tends to practice trial and error methods to choose the best wire mesh combination for their process. At this point, the role of RajFilters begins. We provide a complete filtration solution and expert guidance to choose the best suitable wire mesh combination so that the customer can get the hassle-free desired outcome.

Genuine and good quality extruder screens are typically made using Stainless Steel 304L or 316L grade material. The use of these specific grade materials is due to their effectiveness against the molten plastic’s pressure and temperature. Moreover, due to the high tensile strength of the stainless steel, the screens can be cleaned and used multiple times till the aperture size is disturbed.

Various cheaper options are available, may be cheap initially in price but prove EXPENSIVE at the later stage.


Manufacturing a quality extruder screen requires the utmost attention at every stage. At RajFilters, we start by choosing the best quality, high-grade stainless steel wires, which we procure from our approved vendors renowned for supplying the raw materials at a consistent and accurate rate.

The quality of the wire is thoroughly checked by our Quality Control Engineers, verified by the suppliers’ QC report, and documented.

Then the art of the masterly weaving process starts by considering ASTM standards. The weaving of wire mesh is a too specialized technic that is uncommon for the mass. Our next-generation High-Tech machinery are yielding fine quality and high-speed production.

Our skillful engineers inspect all the aspects with great care, and the outcome turns to be an error-free, consistent, and finely woven wire mesh.

The wire mesh is then calendared and slit as per the production requirement. After that, the slitted wire mesh rolls are sent to the power press department, where a suitable mold is set on the machine.

The mold plays a vital role in producing High-Performance Extruder Screens. Before the commencement of production, our molds are inspected and documented to ensure smooth functioning.

If the mold is not inspected prior to use, the chances of burr while punching is almost certain. The burr hinders the extrusion process by slipping inside the filtered melt, degrading the quality of the finished product.

The extruder screens are then sent to the welding department where various screens are precisely stacked together and welded.

Welding is another important process where the chances of rejections are high if carried out inappropriately. We use high-tech welding equipment to avoid defects in our manufacturing.

At each and every stage of producing the extruder screens, we emphasize carrying out documented quality control inspections. This helps us to control the rejection and the extruder screens are produced as per the strict guidelines and specifications of our reputed customers.

The punched extruder screens are sent for the final inspection and then they advance toward our ultrasonic cleaning facility. The washed screens are then dry-cleaned and sent for packing.


Globally, there are various Extruder Machine Manufacturers having their unique mechanism and spare specifications which also includes the shape and size of the breaker plate. A unique breaker plate design means a unique extruder screen design too.

Over Four decadesRajFilters and Wiremesh Pvt. Ltd. have provided complete filtration solutions to manufacturing Masterbatches, Polypropylene yarn, PP Spun bond fabrics, Plastic Granules, Non-woven fabrics, PVC Compounds, Blown Films, etc. This has helped us to understand the various specifications and precise requirements of our customers.

Due to such longevity in this field, we have developed almost every kind of mold at our manufacturing facility. We pass on this advantage to our customers by not levying the additional cost of mold development. Since the molds are readily available, we take the least possible time to produce extruder screens for our customers.

There are an en number of extruder screen suppliers worldwide. But at RajFilters, all the manufacturing process takes place under one roof. We have complete command of our quality, which makes us different in producing the real world-class, most economical, and accurate wire mesh extruder screen.

Lastly, to summarize the above, RajFilters believes in the precious advice of Mahatma Gandhi –“it’s the quality of our work which will please God, not the quantity.”
