Twin Screw Extruder

The twin-screw extruder is developed on the basis of the single-screw extruder. And it is a key component in this process as it plays a crucial role in determining the final product quality and efficiency. So welcome to contact us.

How does a twin screw extruder work?

The FPL twin screw extrusion machine consists of two parallel screws that rotate in opposite directions and are housed inside a barrel.

Feeding the raw material into the barrel through a hopper. And transporting them through the screws towards the end of the barrel. In addition, the screws are designed in such a way that they compress and heat the raw material to a specific temperature range. Thus converting it into a homogeneous mixture. Then forcing this mixture through a die and cooling it to form the desired product.

What is the main component of twin screw extruder?

There are three components in this machine: extrusion system, transmission system and heating & cooling system.

Extrusion system

The extrusion system mainly includes feeding system, screw and barrel. Furthermore, it is the core part of the extruder. And the screw is the key core component of the extruder. So the main function of the extrusion system is to melt and plasticize the polymer material to form a uniform melt. In addition, realizing the transition from the glass state to the viscous fluid state.

Transmission system

The transmission system is usually composed of a motor, a reducer and a bearing. And its function is mainly to drive the screw and supply the torque and torque required by the screw in the extrusion process.

During the extrusion process, the screw speed is required to be stable to ensure uniform product quality. However, under different circumstances, the screw speed needs to be adjustable. So that the same equipment can be adapted to extrude different materials or different shapes products.

Heating & cooling system

The heating and cooling system of the extruder consists of a heating device and a cooling device, which is a necessary condition for the smooth operation of the extrusion process. And the heating device and cooling device must ensure that the temperature conditions meet the process requirements.
