BARR Inc. offers strong design and support to assist our customers in fully characterizing their resin and optimizing a screw design for maximum performance. In addition to our extensive database on screw designs and material properties, we also have access to the following material testing equipment through Dr. Chan Chung at Rensselaer Polytechnic Institute. Test Equipment Viscosity & Mixing Test 1. Instron capillary rheometer. 2. Haake torque rheometer with mixing bowl and single screw attachment. 3. Weissenberg cone and plate rheometer. Thermodynamic Properties Differential scanning calorimeter (DSC) Melting test Screw Simulator: Developed by Dr. Chan Chung. Used to determine the specific melting rate of a resin. From the time BARR Inc was incorporated in 1976, our focus and commitment to the plastic industry has always been to maximize machine efficiency and product quality. As a result of our dedication and in-depth research, BARR Inc supplies the most successful and innovative designs to the plastic industry. Let us incorporate our technology in your process. E.T. Screw The E.T. (Energy Transfer) Screw is another exciting innovation in extruder screw design, a field in which Barr has consistently been on the leading edge. Barr-3 Screw The Barr-3 Screw is a significant step forward in plastic extrusion technology. The Barr-3 Screw maximizes melting with low energy input and high uniform output by controlling the melting process via an innovative channel design. The Fluxion Mixer A low shear floating sleeve cavity transfer type mixer. The Barr VBET Screw The new Patented BARR VBET design significantly increases conductive melting such that much higher rates are seen before encountering melt fracture
