Tubes & Cores - Coretec™, Naltex™, and Conwed™

Coretec™ Machined Parts & Tubing are designed to meet aggressive customer demands related to temperature extremes, chemical resistance, moisture & product performance requirements. Coretec Machined Parts can be integrated with other SWM advanced netting & nonwoven materials to provide turn-key quality products.

Our Conwed™ extruded rigid tube and Naltex™ extruded cage are manufactured through a single-step continuous extrusion process that yields a plastic material with integral joints. All of our extruded cylinder tubes have a square mesh netting configuration, and in comparison to seamed netting tubes, extruded cylinder tubes are stronger due to their consistent cylindrical shape, made in one single-step.
Extruded cylinder tubes are generally used to support, contain and separate. Most common applications are in filtration, where extruded cylinder tubes provide strength and rigidity to protect delicate filtration media.  Our extruded tubes are manufactured following the same process as our extruded netting.
