Once again, Bedford Technology is proud to offer three uniquely distinct plastic board manufacturing techniques: Molded (Hard Tool), Continuous Extrusion (CE) and Multi Stage Extrusion (Multi-X). Our final process explored in this series of blog postings, is referred to by Bedford Technology as Multiple Stage Extrusion (Multi-X) plastic lumber manufacturing. This process is used to produce 100% recycled plastic boards in our SeaPile®, SeaTimber® and SeaCamel® marine product lines.
The Multiple Stage Extrusion, also known as co-extrusion (or Multi-X) process, involves two or more extruder machines, each producing one extrudate material. The multiple materials are channeled through a single die. This usually produces a skin of material on the product surface, which is different from the material at the core of the final product.
Multiple Stage Extrusion recycled HDPE plastic lumber is utilized for large cross sections, at long lengths (up to 100’ or more) to be used in a structural application. This would include, but is not limited only to, many marine applications such as: fender piles and systems, structural piles, bridge protection, guide walls and locks, corner fenders, dolphins, navigational markers, wales and bullrails.
Bedford Technology’s plastic lumber serves as a replacement to traditional wood profiles, wood piles, concrete piles, steel piles and hollow piles (fiberglass). Bedford Technology can also design a custom plastic lumber product to suit your specific application, so contact us today at (800) 721-9037 and talk with one of our knowledgeable sales representatives.
