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.
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.
The price you can expect to pay for extruder screens is going to depend on a number of factors including:
- Size
- Shape
- Number of layers
- Quantity purchased
- The cost of each individual mesh specification chosen
- Any special processing required
- Alloy
A rough estimate on cost would be about $.20 each for small single-layer screens bought in high volume to well over $20 each for large multi-layer screens bought in low volume.
While good extrusion screens are a quality product, they are made to be used, changed, and discarded at regular, frequent intervals.
How often they need to be changed out is going to be dictated by your processes, how dirty the melt is, or how much of the impurity needs to be taken out.
Screens with clean melt running through them could last days or weeks without change/replacement, while dirty recycled material may need the Extruder Screen replaced several times per hour.
