Spiderless Pipe Die Touts Material Savings
Capable of providing a finished extrusion with OD from 2 in.-15 in.
A new Spiderless Pipe Die from Guill Tool is said to provide increased material savings compared to conventional basket dies for pipe and tubing extrusions. In the design, polymer flows through a distribution plate very similar in design to a breaker plate. Guill describes this plate as a disc into which many small flow passages are machined in a randomized pattern. This is said to distribute the polymer flow evenly around the circumference of the die body.

This new die is capable of providing a finished extrusion with OD from 2 in.-15 in. It’s offered in 4140 steel, or stainless with heat treating.
Guill says material savings are realized due to precision machining, its ability to do flow analysis, and its engineering and design capabilities, among other things.
