Melt flow testing (ISO 1133, JIS K 7210, ASTM D1238 as a general method and ASTM D3364) is a simple way to characterize the flow properties of a plastic melted mass. This test method is widely used, especially in quality assurance and goods inwards testing. Demands on the extrusion plastometer vary according to which processing stage in the plastics industry is involved. ZwickRoell has an extrusion plastometer to suit every testing volume. Learn more how test sequence can be automated over a wide MVR range, which to a great extent relieves personnel from the task of entering the correct test parameters. This makes work in the lab more efficient and ensures reproducibility of your tests when using different instruments at different locations, operated by different users.
