Compounding Extruders
Co-rotating twin-screw extruders, counter-rotating twin-screw extruders, and lab testing machine
Co-rotating twin screw extruders for polymer compounding
Harden develops co-rotating twin screw extruders for plastics compounding. Our co-rotating twin-screw extruders are featured with integrated bimetallic coated barrels, high torque, and high throuighput.
Counter-rotating twin screw extruders for PVC compounding
Harden develops counter-rotating twin screw extruders for PVC compounding. Our counter-rotating twin-screw extruders are featured with sectioned barrels, in-house made high torque gearboxes, and high throuighput. Harden also supplies PVC powder mixers and two mills for color testing.
Small Two-roll Mill for PVC compounding Testing
Harden two roll miller is an ideal option for mixing, sample sheet making for color check.
Main Features of Two Roller Mill Robust design
Two independent PID constant temperature control for the two roll.
Roll surface is quenched and chromate, supported by graphite self-lubricated bearing.
Anti-corrosion painting.
Mini Blown Film Machine
Hardem film production simulation for polymer development, materials evaluation and parameter monitoring requires highly adaptive small scale systems with complete process functionality. The mini blown film system, provide a means of accurate thin film production for total process evaluation, by producing a thin-walled tube which is inflated using compressed air to form a thin circular film.
The films produced during this process can be used for:
Simulating the production process
Testing for gel particles
Testing the pigment distribution
Testing the transparency
Testing the colour distribution
Testing the homogeneity
Testing for contamination and occlusions
Testing die mechanical properties of the polymer
