    No, this isn’t a lesson in parenting, though reflecting back on raising our daughter, the thought is certainly applicable! The point is that consistency is just as important in our dispensing processes as it is in our parenting experience!

    Let’s examine why…

    The Interaction Between Temperature, Pressure, Liner Weight, and Placement

    Posted by Mike Bonner

    Nov 3, 2016 11:36:00 AM

    In our recent blog, Can Liner Weight Variations Impact Quality, Delivery, and Cost Structure, we noted that the two most important criteria in evaluating liner performance are:

    1. Volume of the sealer applied
    2. Placement of the sealer (called “compound”)

    Throughout this series, we have also related these two criteria to variations in temperature, but in reality, there is an interplay between all three.

    Daily vs. Seasonal Temperature Changes

    I often get the comment:

    “I understand the issues associated with the big changes from season-to-season, but the changes from day-to-day are gradual.  Isn’t it pretty easy to compensate for those?”

    And then, mother nature comes along and provides the perfect demonstration of the issue.

    Why Do We Play With Our Coating Formulation?

    Posted by Mike Bonner

    In the last blog, I told the story of Dan, a friend of mine that runs a top-notch coating operation here in the Midwest and the problem he was experiencing during this extended cold snap we have been experiencing.  (Click here if you missed it or want to review)  In the end, Dan’s problem was caused by adding too much solvent in an attempt to adjust for the increase in viscosity caused by the colder paint temperature.

    To remind us that we are in the dead of winter here in the Midwest and across the Eastern Seaboard, Mother Nature has been delivering sub-zero temperatures and snow by the foot.  These are the times that try a coater’s soul!

    Sometimes, the Cynics Get It Wrong- or "Yes, I work in temperature control, but..."

    I did a presentation a few months ago and the sponsor asked me to turn it into an article for their industry journal – which I was only too glad to do!  Once submitted, it was subjected to peer review – a common practice – and one I never give too much thought.  I’ve done it lots of times – and I guess it was bound to happen – this time it went sideways…

    My System Uses a Shot Meter, Why Do I Need Temperature Control?

    Posted by Mike Bonner

    Feb 11, 2014 12:26:00 PM

    This is a great question!

    It seems that there is a prevailing attitude out there that the implementation of shot meters or other flow control systems eliminate the need for any other kind of control.  And it isn't without some basis in logic.  After all, shot meters and flow control systems are designed to assure that exactly the same volume of material will be applied, over the same time period, on every dispense, time-after-time-after-time…

    Point of Application - The Temperature Control Envelope

    So you’ve spent tens or even hundreds of thousands of dollars on your dispensing system, and still you experience quality holds and rejects from your customer – all related to your fluid dispensing operation.  Your best and brightest have analyzed your system and everything is working exactly as designed, yet you are still plagued with these seemingly random episodes.
