Do corrosive chemicals and high torque forces wear down your twin screw drive system? We manufacture high-performance Corrosion Resistance ZE77 Involute Inner Spline Neutral Screw Elements and Kneading Blocks.
ZE77 extruders utilize an involute inner spline design to handle massive drive torque safely. Therefore, we machine every inner profile to exact involute gear standards. Furthermore, our 90-degree neutral kneading blocks provide maximum energy input and intense dispersive mixing without generating unnecessary forward pressure.
We craft these ZE77 elements from premium nickel-based alloys, stainless steels, and bimetallic materials. As a result, our components resist severe chemical corrosion, prevent spline stripping, and ensure long-term mechanical reliability in demanding processes.

High-Torque Involute Inner Spline Drive:
We precision-grind the involute spline teeth inside every element. Consequently, the teeth distribute mechanical stress evenly across the shaft, preventing shaft breakage and spline distortion under heavy torque.
Neutral 90° Geometry for Intense Dispersive Mixing:
Our neutral kneading blocks feature a 90-degree stagger angle. Therefore, they hold raw materials in the shear zone longer, breaking down pigment agglomerates and difficult fillers effectively.
Superior Resistance Against Chemical Attack:
We select specialized nickel alloys and acid-resistant steels. Thus, our components withstand organic acids, halogenated polymers, and reactive additives without pitting or scaling.
Precise Self-Wiping Clearance:
We machine all outer profiles using CNC grinding centers. Because of this, the inter-meshing elements wipe each other continuously and maintain uniform melt temperature.

Our corrosion-resistant ZE77 involute inner spline elements perform reliably across aggressive chemical and polymer processes:
Fluoropolymer Compounding: Processing corrosive materials like PTFE, PVDF, and FEP that release aggressive gases at high temperatures.
Reactive Extrusion & Polymerization: Mixing liquid monomers, catalysts, and active chemical agents continuously.
High-Pigment Dispersive Mixing: Utilizing 90-degree neutral kneading blocks to break down stubborn titanium dioxide and carbon black agglomerates.
Devolatilization & Monomer Stripping: Creating strong distributive shear to release volatile organic compounds (VOCs) from polymer melts.
Flame Retardant & Acidic Additive Compounding: Handling high loadings of halogenated flame retardants and acidic processing aids safely.
A: Involute splines feature curved tooth flanks that distribute torque evenly around the shaft circumference. Therefore, they carry significantly higher drive loads without shearing the inner teeth. Consequently, your ZE77 machine operates safely at higher motor torques.
A: Neutral kneading blocks have zero forward or backward conveying effect. Consequently, they increase residence time in the mixing zone and deliver pure dispersive shear. As a result, you achieve fine particle breakdown and homogeneous liquid dispersion.
A: Yes, absolutely. We cut and inspect all involute inner splines using specialized CNC gear shapers and CMM machinery. Therefore, our components slide smoothly onto your original ZE77 shafts with zero play.
