CHICAGO (July 15, 11:25 a.m. EDT) — Merritt Davis Corp. has teamed up with CPS Resources Inc. to offer new production systems for embossed, decorative profiles.
At NPE 2003, Merritt displayed an extrusion line incorporating a Merritt single-screw machine and Conair downstream equipment to form profiles. In the CompoPlast process, a bead of a special thermoplastic compound is applied to the profile. The bead is embossed to provide a decorated profile that can be stained in-line.
CPS President Craig Smith said the CompoPlast process is superior to conventional technology where a paste of wood flour, adhesive and solvent is applied as a bead. Such a bead shrinks when the solvent evaporates and solvent emissions are environmentally unfriendly. Operators need to make the wood paste in batches and, once applied, the wood paste takes 24 hours to dry.
Smith said CompoPlast applications include picture frames and decorative moldings. The CompoPlast material sets rapidly and, when cooled properl,y can take in-line spraying, foiling and patina finishing. It resists chipping and the resin adheres to a range of plastic substrates and wood.
CPS of Indian Trail, N.C., said side trim of its special resin is parted cleanly and recycled in-process. Merritt helped CPS adapt its system to profile extrusion.
Other equipment displayed at the NPE booth of Hamden, Conn.-based Merritt included a high-volume reclaim pelletizer unit with a ram to take plastic fluff waste.
