For Sale - PCM - 1941 - Lab Extruder

Neoplast has developed first time in India a fully instrumented single screw and twin screw lab extruders with integrated data acquisition PLC. This machine can be attached to various downstream equipments to carry out varieties of testing like extrudability of polymers, studying the problems occurring in R and D as well as in practical applications. Manifold screws, die heads and downstream equipments fulfill all kinds of extrusion tasks.
The sample material is plastified under practice-oriented conditions and extruded through die head. All measuring values such as torque, melt pressure, melt temperature are recorded continuously and represented in the form of tables and graphs parallel to the running test.

Salient Features
- The Extruder frame is mounted on four caster wheel with level screw arrangement to fix it rigidly on the floor.
- Main motor with AC variable frequency drive and detachable keyboard.
- For attaching various toolings, the barrel flange is provided with hinge type arrangement for quick opening, dismantling and screw cleaning.
- The maximum output is just 5 kg/hr, which prevents wastage of expensive material under testing.
- The maximum processing temperature is up to 400 C which can be controlled by auto tune type, dual display PID temperature controllers.
