This die for PVC and CPVC pipe, built by American Maplan Corp., McPherson, Kan., uses a new head design with optimized orientation of the spider legs to allow knit lines in the melt to fuse together for improved strength, Maplan says. The die comes in single, dual, and quad strand configurations. The first four-strand die of the new design has been in commercial production for a about year on a parallel twin-screw extruder with 6-in. center distance, producing 200 to 350 lb/hr per head of pipe or conduit with 0.375 to 1 in.
