Patented Screw Design
AS&B offers several types of Screw Designs to increase productivity
and quality of Plastics. Many polymers are difficult to Melt and
Mix, in which standard Screw Designs cannot perform without an
increase in shear and overheating. With these types of problems
in mind, AS&B has developed the patented INTERMIXERTM (U.S.
Patent # 5,288,223). This Design imparts a very high degree of
homogenization while at the same time avoiding the overheating
and breakdown of materials associated with the shear developed
by the ordinary Screw. Among the many superior product enhancements,
plasticizing improvement of 30% is not uncommon thus reducing
HP requirements by a healthy 15% and in some cases improvements
in recovery time are a staggering 400%.
In the Manufacture of Barrels, AS&B offers several Bimetallic
Inlays for types of applications that require:
Extreme Wear & Corrosion Resistance.
Steels and Nitralloy 135 (mod) are other alternatives depending
on your Processing Application.
