Our experience and knowledge of the needs of the extruder user coupled with our comprehensive stocks of woven mesh in all materials enables us to offer screens for most sizes of extruder.  
 
These can be single screen, spot welded multi layer and metal rimmed packs. 
We also provide single and multi mesh cylinders as well as the more sophisticated shaped screens.  
 
Based on this we can offer a high quality product at an extremely competitive price and excellent service coupled with short delivery times. 

CALDWELL EXTRUSION FILTERS 

Caldwell Extrusion Filters are our one of our companies primary products, we ensure that the quality of these meshes are not compromised as poor standard/less expensive meshes often don't last and blow sooner than get used.  
 
Our weld packs are made up you your requirements taking into account flow rate and plastic quality and our rimmed packs are for your higher pressure filtering. What ever your needs we know we can help. 

CALDWELL SCREENS 

Caldwell Screens e.g. Rotex are self-contained production screening machines for separating dry materials by particle size, through the unique gyratory motion of the horizontal screen surface, combined with a positive screen mesh cleaning system.  
 
These screens provide unusually high efficiency and capacity, all the result of continuous development for hundreds of applications throughout scores of industries in many countries. 
Screens utilise a unique screening action that provides both accuracy of separation whilst maintaining production rates. Materials are fed into the top of the machine and it is distributed over the entire width of the screen surface and then conveyed to the discharge end.  
 
Larger particles remain above the screen surface while smaller particles pass through as determined by the aperture sizes selected for each screen mesh for the particular application. 
Screens can be supplied with one to five screening surfaces producing between two and six separate product grades. 
 
Caldwell's Wire mesh Screens can be supplied with PVC taped edges and metal eyelet's and are available with wear strips if required.  
 
Caldwell's Tensioned Screens can be supplied new or for customers existing screen frames can be re-meshed.
