Protected against the toughest wear
For single and twin-screw extruders, 3S supplies the right barrels for the right material. The big advantage is that everything comes from a single source and includes enhanced quality and an innovation in conical twin screws.
Your advantages in a nutshell:
In nitrided or bimetallic spun qualities. Barrels in every possible specification. Grooved bore or smooth inside, with various cooling systems.
Screw accessories such as parts for mixing and shearing, screw tips and non-return valves are also part of the wide 3S product range.
Your advantages in a nutshell:
We deliver conical and parallel twin-screw barrels as well as barrel sections for compounding machines. Twin screw extruders with the wear sleeve inside the barrel designed by the 3S development team.
The advantage of this hardened tool steel sleeve is that it can be replaced completely and as often as required if it is subject to wear. This greatly increases the service life of the barrel as a result.
Conjured out of the barrel.
The barrel design for conical twin-screw extruders used to have one major disadvantage: high wear. In the last 50 years, the design of barrels - featuring surface-hardened material - has hardly changed. Until now.
The 3S development team has conjured out of the barrel what is truly a global innovation: a wear sleeve made of hardened tool steel on the inside of the barrel which, once it has become worn, can be completely replaced as often as necessary. This increases the service life of the barrel considerably as a result. The new technology is manufactured at the 3S location in St. Barbara im Mürztal. The first barrels with removeable wear sleeve were shipped in 2010.
