These extruders are designed exclusively for a variety of medical applications and are typically used in a clean room environment. Our medical line of extruders (MD series) are supplied with a special urethane based medical paint that is more chip resistant and does not “yellow” over time, closed loop AC vector or servo drives for improved speed regulation, and a replaceable feed section liner on all small machines up to 1 inch (24mm) that provides the flexibility to configure the feed geometry to best suit the application. There are many options available to choose from including pressure feedback control that enables small but rapid changes to the screw speed to correct any drifting pressure that is sensed. Melt pump systems are also available on all models.
