In many cases, yes. Adding a vent port stuffer is one of the more cost effective upgrades you can make to an existing extrusion line, especially if the vent is the thing holding your output or quality back.
Screwtech Engineering supplies vent port stuffers in various sizes to suit a wide range of twin-screw and single-screw extruders. That covers a lot of machines already out there on factory floors.
Once fitted, the stuffer lets your existing extruder run at higher fill levels while maintaining product quality. Its self-wiping twin screws keep melt in the barrel, and precision tolerances allow full vacuum to be drawn for proper removal of moisture and volatiles. Less vent blockage means less costly downtime.
Where a machine needs something a bit different, Screwtech can design and manufacture bespoke parts along with modifications, using up to date 3D CAD modelling software.
Every stuffer is built from high quality stainless steel, with an easy clean two-part vacuum chamber, separate seal housing and an oil filled gearbox with water cooled jacket for long life at high temperature.
The best starting point is to send Screwtech your extruder details, the vent you want to use and the problem you are trying to solve. Get in touch with Screwtech Engineering and they will advise on the right fit.
