The co-extrusion process utilizes two or more extruders to melt and deliver a steady volumetric throughput of compatible viscous plastics to a single extrusion die which will extrude the materials in the desired form.
Examples of a co-extrusion could include a rigid and a flexible material or 2 rigid materials. Another example could be a multi-color part consisting of a clear and an opaque material.
The co-extrusion process has many benefits such as cost effectiveness, quality, and sustainability.
