VORTEX® D.H.Z. Crosshead 

With all of the simplicity, accuracy, and speed of the VORTEX®, the D.H.Z. has the die area of the crosshead reduced to create a second heat zone. Visit www.tipsandies.com to learn more!
A second thermocouple port is placed in the die area to allow separate control from that of the main crosshead body. The separate heat zone allows for a potential overall better finish, surface finish (shine), reduction in cone breaks, and helps to eliminate die droll and melt fracture all at greatly increased speed lines.
