TECHNOLOGY OF CO-EXTRUSION

Co-extrusion put simply, is "a tube within a tube." How that happens is as the inside tube is being formed, the outside tube is being formed too. The result is that the two tubes become one. The process has been around for a while. In fact, the colored stripes that are common on drinking straws get there through a coextrusion process. Though the process is not new, LANGBO machinery’s technology development and experience in the fluid power industry, make this a groundbreaking announcement.

THE FUTURE OF CO-EXTRUSION

Although compound plastic products have already found multiple applications in the multi-color extrusion, multi-layer pipe, and energy industries, co-extrusion continues to expand its functional range. Since the effectiveness of its products depends on the combination of plastics used in the process, discovering viable mixtures will shape co-extrusion applications in the future.

COEXTRUDED STRUCTURAL UNITS

Plastic is sometimes used as a substitute for wood. Manufacturers can create decking, boat docks, fences and dimensional components with “plastic lumber,” which has some advantages over natural wood. Co-extrusion is a cost-effective method of fabricating many of these artificial materials. It can add titanium dioxide, a weather resistant material, to exterior structural plastics or produce decking with an inner layer of recycled plastic.
