ZSE75 Reverse Screw Element | Back Pressure Conveying Element for ZSE75 Extruder Spare Parts
Brief Introduction
This ZSE75 reverse screw element is also called back pressure conveying element. It serves as a direct replacement part for ZSE75 co-rotating twin screw extruders. First, it adopts a reverse helix structure. It slows down the forward flow of materials and builds stable melt back pressure inside the barrel. Then, it extends material residence time inside the machine. It makes plastic melting and material mixing more uniform. Besides, it fits original parts perfectly. It suits multiple production scenarios such as plastic compounding, masterbatch production, plastic recycling and filled material processing.
Key Functions
-
Build stable backpressure: It slows down material delivery and creates steady, adjustable extrusion pressure.
-
Extend material residence time: It allows polymer melt to fully melt, blend and react inside the extruder.
-
Improve mixing quality: It cooperates with kneading blocks to solve uneven mixing issues and deliver consistent material performance.
-
Optimize devolatilization effect: Workers install it in front of vent zones to remove moisture and volatile impurities more thoroughly.
-
Support modular assembly: It fits standard ZSE75 spline shafts. Users can freely combine it with regular conveying elements and kneading blocks.

FAQ
Q1: Can this reverse element replace original ZSE75 parts directly?
A1: Yes, it fits 100%. We make all dimensions, splines and profiles strictly per original standards. You can install it directly on your ZSE75 extruder with no adjustments needed.
Q2: What’s the difference between reverse screw element and normal forward element?
A2: Forward elements speed up material delivery. On the contrary, reverse elements slow down material flow to build steady back pressure. This extends material residence time, improves melting, mixing and devolatilization, and greatly boosts your final extrusion quality.
Q3: How to pick the right material for my production?
A3: Choose 38CrMoAlA nitriding for regular production for great cost performance. Pick WR5 or high-speed steel for medium wear with common fillers. Select SAM26 or CPM10V for high-filler, abrasive and corrosive materials for longer service life.
Q4: Can you customize size and structure?
A4: Yes, we offer full customization. We adjust pitch, length and structure based on your screw drawings and production needs. We also provide free technical optimization suggestions for your extrusion issues.
Q5: What’s your delivery time and quality warranty?
A5: We deliver standard parts in 3-7 working days, and customized parts in 7-15 working days. We test every product strictly before shipment. We also offer a 1-year warranty under normal working conditions.
Q6: Will reverse screw element cause material blocking?
A6: No, it will not block materials. Our self-wiping design and precise gap keep smooth material flow while building back pressure. It has no dead corners or material buildup for stable long-time operation.
Q7: Do you offer sample service and technical support?
A7: Yes, we support sample testing. Meanwhile, our team provides free screw matching guidance, process parameter advice and full after-sales technical support for your production.
