The Ringwood RS-3000 Starch Mixing System

Years of Ringwood experience and customer iput from around the world led to the development of the RS-3000, the new world standard for starch mixing systems. Today’s corrugators have to produce more than ever before with increasing quality requirements. This new reality has increased the need for corrugated adhesive that is extremely high performing, consistent and repeatable. The RS-3000 produces the world’s most consistent starch adhesive.

High Shear

All our systems are based on the concept of high shear. High shear is the process of adding extreme agitation to eliminate the “false initial viscosity” that’s routinely found with Stein-Hall adhesives. The RS-3000 eliminates false readings.



The RS-3000 receives a signal from the adhesive storage tank indicating that a new batch is needed. The system will then automatically add batch ingredients and mix a new batch. The adhesive is then transferred to the proper storage tank.
