Patented Screw Design American Screw & Barrel 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, American Screw & Barrel 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, American Screw & Barrel offers several Bimetallic Inlays for types of applications that require:
Extreme Wear & Corrosion Resistance.
Tool Steels and Nitralloy 135 (mod) are other alternatives depending on your Processing Application.
For your current Barrel, Resleeving and Honing are offered for cost effective ways to improve productivity. Inspections need to be performed to determine if these are options that will improve your current application.
