Co-extrusion is the process of pressing two or more materials through the same die to produce a single piece of sheet or roll with different layers fused together. When multiple plastics are combined, the result can produce properties distinct from those of a single material and can create a different colour layers of the same material.
Co-extrusion is only possible with specialised extrusion capabilities. All three of PRO-FORM's large plastic extrusion lines offer multi-layer co-extrusion options. This capability is taken advantage of for many applications including their automotive products such as the ABS SportLid and canopy.
