The Challenge
Your Process Demands More Than a Standard Machine
A catalog extruder is specified to a generic duty — not your filler load, residence time, or operating conditions. When the line sits far from support, spare delays and missed commissioning become process problems, not purchasing footnotes.
The Testron Approach
Engineered Around Your Material and Production Goals
We do not supply standard machines — we engineer co-rotating twin-screw lines around your material, throughput, and L/D. Manufactured in Bangalore, with regional support from Ajman for commissioning, spares, and servicing across the UAE and GCC.

Engineered Subsystems — Not Outsourced Subassemblies
Every extrusion line is built from in-house screw elements, barrels, shafts, and drive systems — configured for your material, filler load, and downstream process.
Twin-Screw Elements (Ø14 mm – Ø97 mm)
Modular segmented design for conveying, kneading, mixing, reverse, and barrier applications.

- Wear-resistant metallurgy with nitriding and hard-facing options
- Balanced for high RPM stability up to 1200 rpm
Barrel & Barrel Liners
Replaceable liner design that reduces maintenance cost and extends barrel life.
- Superior wear resistance for abrasive compounds
- Precision-bored for optimal screw-barrel clearance
- Nitrided and bimetallic liner options for corrosive applications
Gearbox & Shaft Drive
Heavy-duty extruder gearboxes and shaft systems built for high torque transmission and long service life.
- Precision-ground helical gearing
- High torque capacity for demanding compounds
- Coupling configurations for high filler loads
Melt Pumps & Auto-Filtration
Stable melt pressure control and filtration for consistent output and extended downstream equipment life.
- Stable melt pressure and reduced pulsation
- Improved output consistency across the line
- Replaceable screen packs for auto-filtration
MODULAR SCREW ELEMENTS
Five Element Families — Engineered for Your Compound
In-house screw elements from Ø14–97 mm, configured for conveying, kneading, mixing, reverse, and specialty process zones. Wear-resistant metallurgy with nitriding and hard-facing options — matched to filler load, dispersion goals, and your existing screw configuration.
Conveying Elements
Reliable forward transport
Forward-flight elements move polymer and additives through feed, melting, and transfer zones with controlled fill. Configured for your screw diameter, L/D, and throughput target.
- Optimized flight geometry for stable material flow
- Sized for Ø14–97 mm modular screw builds
- Balanced for high-RPM operation (size-dependent)
- Wear metallurgy for filled and mineral-loaded compounds
Kneading Elements
Controlled shear and dispersion
Kneading blocks deliver targeted shear for pigment dispersion, additive distribution, and filler wet-out. Available in 30°, 45°, and 60° configurations to match your compound and mixing intensity.
- 30°, 45°, and 60° kneading angles for process tuning
- Dispersive mixing for masterbatch and compounding
- Wear-resistant tool steels with nitriding / hard-facing
- Configured with conveying zones for balanced fill
Mixing Elements
Homogeneous melt preparation
Mixing elements homogenize melt before downstream devolatilization, reaction, or pelletizing zones. 66° and 90° profiles support distributive mixing without excessive energy input.
- 66° and 90° mixing profiles for distributive blending
- Supports devolatilization and reactive extrusion zones
- Matched to polymer viscosity and filler percentage
- Modular placement along L/D 24–60 screw builds
Reverse Elements
Fill control and back-mixing
Reverse conveying and reverse kneading elements create controlled back-pressure and fill-length management in critical screw zones. Used to balance melting, mixing intensity, and vent performance.
- Reverse conveying for fill-length and pressure control
- Reverse kneading for localized back-mixing zones
- Supports devolatilization and vent-section stability
- Configured as part of full screw profile review
Special Elements
Purpose-built process zones
Gear/toothed mixing, barrier, and combination elements address demanding dispersion, melting, and multi-stage process requirements. Engineered for abrasive fillers, high mineral load, and specialty compound profiles.
- Gear / toothed mixing for intensive dispersive action
- Barrier elements for melting and mixing separation
- Combination elements for multi-function screw zones
- Metallurgy selected for abrasive and corrosive compounds
