Unplanned downtime is expensive. Lost output, wasted material, labour stood waiting and a restart that rarely goes smoothly. On a lot of extrusion lines, the vent port is a regular cause of it.
Melt rises up the vent, gets into the port and the vacuum line, cools and builds up. Eventually the vent blocks, degassing stops and the line has to come down for cleaning. Then the cycle starts again.
A Screwtech Engineering vent port stuffer breaks that cycle. Its self-wiping twin-screw design pushes rising material back into the barrel and keeps the screws clean as they turn. Nothing sits in the port long enough to build up, so the vent stays open.
That helps minimise inconvenient and costly downtime through vent port blockage. And because precision tolerances allow full vacuum, you are not trading reliability for product quality.
When planned maintenance does come round, Screwtech makes it straightforward. The easy clean two-part vacuum chamber and separate seal housing make access simple. The oil filled gearbox with water cooled jacket is built for long life at high temperature, and the stainless steel construction suits demanding production environments.
Screwtech supplies vent port stuffers in various sizes for twin-screw and single-screw extruders. If vent stops are eating into your production hours, get in touch with Screwtech Engineering.
