Overview

Hot Melt Extruder

Melt extruder is the new mixer extrusion range that builds on the proven Umang technology and its benefits. Similar design of the twin screws, extrusion die and cutting mechanism in the process and validation, so that there is no difference to the extrusion process. This unique design of segmented twin screws, mixing attachments and cutting makes the not only a perfect hot melt extrusion granulator but also an ideal machine for performing one stop operations.

The outstanding feature of the Melt extruder range is the the twin screw segmented barrel and twin screw feeders attached to it for uniform and continuous product feeding. Connections, cabling and supplies are completely integrated, covered and sealed so the outside of the machine is smooth and very easy to clean. Our system Melt extruder is a result of high level of engineering expertise and product technology knowledge, quick product changeover increases productivity and cost effectiveness.

The Melt extruder capacity ranges from few 100 gms. to 150 kgs. / hr. featuring through the wall design and movable head, allowing operation with platform and dust-free discharging via a linked mill directly into an IBC. The Melt extruder can be stand-alone or linked to a Cone Mill or Multi Mill to form an integrated system.

With its special versions of the twin-screw extruder suitable for the production of pharmaceutical compounds, Umang is one of the pioneers in the development of Pharmaceutical Hot Melt Extrusion. In this continuous production process, polymers are mixed with binding materials, carrier materials and active pharmaceutical ingredients (API’s). This innovative, flexibly applicable process has recently become increasingly important.

No, the extrusion chamber is on hinges completely dismantlable and cleanable.

Are the screws of segmented design?
Yes the screws can be arranged in a design best suited for the customer products, the segmented screw is completely configurable.
drying/coating as per product / process needs.

Can a Spheronizer be coupled with a twin screw extruder to give hot melt pellets ?
Yes , a jacketed spheronizer.

Is the Extruder and powder feeder controlled by a inverter?
Yes.
