Maplan die enhances properties of pipe
Extruder maker American Maplan Corp. has developed a spider-type die head for producers of small-diameter PVC pipe, chlorinated PVC pipe and PVC conduit.
The die has optimized flow geometry that allows the knit lines of the spider to fuse together as a homogeneous melt before it exits the die. Maplan said that improves the physical properties of the pipe.
The tooling is designed to run about 200-350 pounds of pipe an hour.
A major advantage is the small size of the housing, which allows for dual-strand extrusion at a center distance of 6 inches, or quad extrusion using Maplan's flow separator.
