At an event recently, we struck up a conversation with an Account Manager at one of the major paint suppliers. During our conversation we discussed the batch-to-batch variation of the paints they supply. He said what we often hear from paint suppliers, “Our paints don’t vary much from batch to batch.” When we asked why their customers often have a different perception he said, “Most of the variations that they see are self-inflicted.” That prompted us to request a more in-depth conversation so we could better understand how end users may be unknowingly creating their own batch variations. We thought his insights were helpful, so we decided to share a summary of them here.

In this series we’ve been discussing the impact of changes in fluid properties, specifically viscosity, on the performance of robotic fixed displacement dispensing systems. In the first installment, “Fixed Displacement Dispensing Doesn’t Guarantee Fixed Results”, we examined common dispensing defects, contrasting those that can be readily addressed through the implementation of a robotic fixed displacement dispensing system, and those that are the result of changes in physical fluid properties, which prove to be more resilient.

In our last segment, Fixed Displacement Dispensing Doesn’t Guarantee Fixed Results, we examined how viscosity variation impacts your robotic fixed displacement dispensing system and the many defects that can still exist, even in the most highly advanced of these systems. In this installment, we look more closely at the phenomenon of bead profile, it’s importance to the quality of your end product, and why simply controlling path, dispense rate, and total volume does not guarantee that your process will produce consistently high-quality parts.

It has become commonplace to employ fixed displacement systems when dispensing mid-to-high-viscosity fluids like sealers and adhesives. It makes sense. Proper performance in these applications hinges on making sure that the right amount of sealer or adhesive is dispensed in the right place on every part. When coupled with a robot to assure that path, speed, distance and angle to part are consistent and repeatable, it is easy to believe that the dispense job will be perfect every time.

In Part II of this series, we continued our discussion on viscosity by tackling the topic of thixotropy. With this defined, we can now circle back to bring it all together and show how different measurement methods produce different results and how our measurement choices can actually work against us.

In Part I of this series, we examined some of the issues with the viscosity cup measurement process and started to look at the fundamentals of fluid viscosity as a means of explaining the source of those problems. In this installment, we pick up the discussion with a somewhat difficult topic: thixotropy.

Manufacturers who dispense fluids in their process (i.e. – paints and coatings, sealers and adhesives, potting compounds and encapsulants, etc.) all understand that the viscosity of that fluid is fundamental to the process out

I recently received an e-mail from BV Thermal Systems, a supplier of chillers, that caught my eye. It opened with a statement that is all too familiar in our world of temperature control:

The modern paint shop is a maze of pipes and tubes carrying paint all over the place! Some of these circulation systems even have temperature control systems designed to make sure that the paint temperature is controlled as it is circulated. So why is paint temperature still such an issue?
