If you're in the medical device industry, you've likely heard of the twin screw extruder. Unlike the single-screw extruders, twin-screw extruders can be configured for specific processes and a wide variety of materials. These extruders have a number of distinct advantages.

An intermeshing twin-screw extrusion machine is a complicated machine with many moving parts. This type of machine has numerous control parameters, including screw speed, feed rate, and temperature. In addition, it also has the capability of monitoring a range of other parameters, such as melt pressure. These extruders are often controlled through a HMI screen.

Twin-screw extruders have high speeds and torque. These features are particularly beneficial for the processing of heat-sensitive and high-viscosity materials. There are several different types of twin-screw extruders, each with its own specific characteristics. For example, an intermeshing counter-rotating twin-screw extruder is an excellent choice for the production of profile or pipe products from PVC materials.

Two basic designs of intermeshing twin-screw extrusion machines are available. One is a low-speed late-fusing (LSLF) configuration, while the other is a high-speed energy input (HSEI) model. The LSLF mode is a widely used extrusion machine in the plastics industry for the shape extrusion of polyvinyl chloride profiles, with thousands of installations worldwide.
