Interfacial Surface Generator (ISG) static mixers from Charles Ross & Son Co. (Hauppauge, N.Y.) can be quickly installed in existing meter/mix/dispense (MMD) equipment piping at low cost. Four holes bored through each element split the resin into layers, recombine it, then split it again. The ends of the elements are shaped so that adjacent elements form a tetrahedral chamber. Two input streams entering an ISG static mixer are split into more than two million layers in just 10 elements. Available in stainless steel, polypropylene and Teflon, ISG elements reportedly are well-proven for thorough mixing of high viscosity ratios (up to 250,000:1) in a very short length of pipe, and the elements can be removed for individual cleaning.
The latest equipment solutions deliver lower costs, faster cycle times and better part properties.
Suppliers of meter/mix/dispense (MMD) equipment are under pressure to keep pace with proce...
