Description

A bi-color extruder is a mechanism or machine designed to process, melt, and push two distinct colors or types of materials simultaneously. Depending on the context, it typically refers to either industrial co-extrusion manufacturing lines or 3D printing equipment.In industrial manufacturing, a bi-color extruder uses two separate barrels and screws to feed two different plastic or rubber streams into a single die. This co-extrusion process is widely used to manufacture dual-colored consumer products, automotive trim (such as weather-stripping with a rigid core and flexible, colored edge), and multi-colored 3D printing filament.
