Bedford Technology is proud to announce our collaboration with AEC Daily on a continuing education course, geared towards educating architects/engineers on the uses of HDPE plastic lumber products. This course, Recycled HDPE Plastic Lumber: Performance Characteristics & Applications, has been designed over the last few months and incorporates all three unique design processes utilized by Bedford Technology, including: Molded (Hard Tool), Continuous Extrusion and Multiple Extrusion (Multi-X). The course also goes into comparisons between HDPE (High Density Poly Ethylene) plastic lumber and other composite lumbers.
The Bedford Technology continuing education course, Recycled HDPE Plastic Lumber: Performance Characteristics & Applicationswent live May 1st, on AEC Daily’s Online Learning Center (OLC). The course may be viewed here at www.aecdaily.com/sponsor/bedford.
Bedford Technology’s plastic lumber serves as a replacement to traditional parts made from injection molding, rotational molding, vacuum forming, aluminum extrusion, flow molding, lumber profiles and wood profiles. 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.

The Hard Tool (or molded) process is similar to injection molding. The molten plastic material with additives (UV stabilizers, colorant, strengtheners, etc.) is forced, under pressure, through channel runners and gates into a finite mold. The molten HDPE recycled plastic is pressure packed to the net shape of the mold and allowed to cool until it is solid. Larger molds take hours to cool, so the molds are disconnected and rotated around to the extruder between the fill, cool, and part removal steps. The output typically is a single or multi cavity linear shaped plastic lumber part run in a horizontal line set-up. (See image for diagram) It can also can be a large custom molded shape (i.e. the leg of an outdoor park bench, cribbing block, etc).
