    The Pitfalls of Smaller Automation

    With robot costs in the tens or even hundreds of thousands of dollars, automated dispensing used to be the domain of large, well-financed companies in industries like automotive, aerospace, aeronautics, etc.

    How Much Does Your Material Change During Your Dispense Process?

    Posted by Rob Gladstone

    Jan 29, 2020 9:37:00 AM

    Before I get into how much your material may change during your dispense process, let me provide a quick summary of why it matters. As your plant temperature changes, your material temperature often changes. When material temperature changes, the viscosity changes. When viscosity changes, the end result of your dispense changes – and nothing good happens when your finished product varies. It causes rework, scrap, customer rejects and in some cases, early product failure. In this blog, we’re going to address the effects of material temperature only. There may be other factors affecting your material but they’re not going to be addressed here.

    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.

    Can Temperature Change Disrupt My Fixed Displacement Dispensing System?

    Posted by Mike Bonner

    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

    Posted by Mike Bonner

    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.

    Why Does My Temperature Change Between My Circ System and the Point of Application?

    Posted by Mike Bonner

    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?

    Heat Exchanger Fluid Velocity – Why Should I Care?

    Posted by Mike Bonner

    Dec 7, 2017 3:02:00 PM

    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.).

    How Saint Clair Systems Made Sealer Behave

    Posted by Mike Bonner

    Jul 13, 2017 8:00:00 AM

    Saint Clair Systems has been a leader in fluid process control systems and viscosity control for nearly three decades, and in that time they’ve managed to revolutionized the industry and change the future of manufacturing operations. Most recently, Saint Clair tackled a sealer dispensing issue at Tata Motors in India, and today we’re going to tell you a little bit about our most recent feat and how we got to where we are today.
