A PIPE COEX CENT DIE FOR HIGH IMPACT PVC PIPE AND METHOD MAKE IT AND HIGH IMPACT PVC PIPE

摘要

The present invention relates to a multi-tube manufacturing method and a multi-tube manufacturing method using a COEX center die for manufacturing multi-tubes capable of producing multi-tubes used for water supply and sewerage, and is a technology applicable to multi-tubes or more. To this end, the flange 10 for coupling to the multi-pipe manufacturing apparatus and the guide jaw 20 and the flange 10 formed in an upward spiral shape on one side of the flange 10 to rotate and move the composition for pipe manufacturing And a compression part for compressing a composition for a pipe which is located next to the inflow part 30 formed by opening a part of the induction jaw 20 and the induction jaw 20 and transferred from the induction jaw 20. Located next to (40) and the compression section (40), the discharge section (50) for discharging the compressed pipe composition from the compression section (40) and the center hole for supplying the pipe composition for the inner skin layer of multiple pipes ( It provides a coex center die for manufacturing a multi-tube consisting of 60) and a manufacturing method and a multi-tube using the same.
