How does it work?

Hot melt extrusion (HME) is a solvent-free, continuous manufacturing process that mixes materials using heat and pressure, and forces the resulting homogeneous mixture into a uniform shape through a die. It is used in many industries where the smooth mixing of ingredients and precise application of heat are required; for example, pharmaceutical, food, cosmetics, plastics, materials science research and battery components. 

Heating or cooling applied in 4-8 zones along the barrel

Die block, which squeezes material out in various shape profiles to be cut, wound, or processed.

1

Feeding the Ingredients: Raw materials, in the form of powders, pellets or liquids, are fed into the top of the extrusion machine.

2

Heating and Mixing: Inside the extruder, the materials are heated and melted while being mixed thoroughly by the turning motion of the twin screws. Our machines apply precise and user-defined quantities of heating at various points throughout the barrel.

3

Pressurizing and Shaping: The molten mixture is pushed (extruded) through a specially shaped opening (die), giving it a particular shape, like strands, sheets, or tubes.

4

Cutting or Processing: Materials can be extruded in specific shapes, or, once solid, can be cut or processed further into smaller pieces or specific products.
