The term pigment covers a wide range of materials and brings with it a host of handling challenges. This customer has over 200 variations to offer its wide customer base, and the bulk density and material properties range from 50 -85 lb./ft3. The customer utilizes intermediate bulk containers, or IBC’s, to move product from its mixing room into the bagging stations to enable quick-ship products.


In the Fall of 2020, the plant was running at near capacity to meet its customer demands. Our client needed to move from a manual process to a more automated solution. The Tinsley Equipment Company team performed a site laser scan of the packaging building to help in the product selection and equipment layout. After the equipment was delivered, the Tinsley team assisted in the start-up, training and on-going support that makes for a strong relationship.
