    WE’RE NOT THE PAINT HEATER COMPANY!

    We hear this a lot, “Oh, you’re the paint heater company.” We tend to cringe because what we do is quite a bit different than traditional paint heaters.

    Are Batch-to-Batch Paint Variations Self-Inflicted?

    Posted by Rob Gladstone

    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.

    Can Temperature Change Disrupt My Fixed Displacement Dispensing System?

    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.

    Why Robotic Fixed Displacement Dispensing Systems Can’t Guarantee Consistent Bead Profiles

    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.

    Fixed Displacement Dispensing Doesn’t Guarantee Fixed Results

    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.

    How Big is Big? (or, “I Need How Much Space for That?!?”)

    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:

    Heat Exchanger Fluid Velocity – Why Should I Care?

    Posted by Mike Bonner

    The heat exchanger is the core device in virtually every fluid temperature control system.  Unfortunately, properly selecting a heat exchanger can be a daunting task.

    First, there is the thermal load that must be transferred. Next are working pressure, flow rate, and chemical compatibility requirements.  Coupled with the thermal transfer, these determine the configuration (gasketed plate, brazed plate, shell & tube, etc.) and the materials of construction (carbon steel, stainless steel, aluminum, titanium, etc.).
