Neoplast has developed first time in India a fully
instrumented single screw & 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
& 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.
