Two barrel section lengths for every screw diameter:
The barrel sections and screw elements of the ZE UTX series are designed in strict accordance with the building block principle. With various types and different specifications that can all be combined with great versatility, there is virtually no limit to the barrel and screw configurations which can be employed to meet your process requirements in the finest detail.

The patented hardening method (DE 101 122 95 B4) for the ZE UTX barrel bores is unparalleled worldwide. Inductive hardening of the figure 8 bore provides excellent protection against abrasion and corrosion for different extruder applications and barrel materials. Barrels made of composite materials are the ideal solution to satisfy the most stringent requirements in terms of wear protection. Where protection requirements are less severe, nitriding steel barrels are used. Costly anti-wear barrel liners are no longer required for the ZE UTX series. Barrel sections with an L/D ratio of 4 or 6 are available for the configuration of the modular processing section. These barrel sections are designed as

• open barrels for feed zones,
• open barrels equipped with inserts for degassing, metering, injection zones or with measuring elements,
• closed barrels,
• combined barrels for horizontal side feeding of additives or for vertical venting.
