Modular Screw Elements
Conveying, kneading, mixing, and barrier elements configured for your compound — wear metallurgy with nitriding and hard-facing for filled and abrasive materials.
Custom Machinery
Twin Screw, Co-Rotating and Counter Rotating Extruder
Varying from Ø14–Ø97 mm (capable up to Ø150 mm, L/D 60).
At Testron Engineering, we manufacture co-rotating twin-screw extruders ranging from Ø14 mm to Ø97 mm (capable up to Ø150 mm, L/D 60), designed to support everything from R&D trials to full-scale industrial production.
Built at our manufacturing facility in Bangalore, India, each machine is engineered with precision screw profiles, heavy-duty gearboxes, and modular barrel systems — ensuring superior mixing, high torque stability, and long service life.
Whether you are developing a new formulation or running continuous masterbatch production, our extruders deliver consistent output, optimized energy usage, and process flexibility.
