New AGR Europe Testing Lab successfully completes first year

Agr International has invested more than 1 Million Euros in the establishment of an American Glass Research Testing Laboratory in Delft, The Netherlands. The lab has completed its first full year of operations and AGR CEO Henry Dimmick declares it has more than met its first year objectives.  “Our goals were to create and staff a state of the art testing laboratory for glass containers and be able to offer all of the same core glass testing services American Glass Research is known for, including: Fracture Diagnosis, Proof of Design Testing, Filling line and Glass Manufacturing line audits, Container Design Study, as well as Label, Decoration and Closure Analysis”,  said Dimmick.

We have installed Agr International produced testing equipment including a Ramp Pressure Tester 2X, Vertical Load Tester, and Pendulum Impact Tester for comprehensive, performance testing of glass containers. Additionally complementary AGR equipment housed at the laboratory includes the following:  Line Simulator, Hot End Coating and Finish Coating Measurement Systems, Tilt Table, Polarimeter and MBTxt thickness measurement guages. State of the art optical and polarizing microscopes along with an array of metrology devices round out the capabilities of the facility.
Peter de Haan, Senior Scientist and Manager of the Delft lab shared that “Our customers have told us that because this location is so convenient, they have been able to reduce testing time and saves themselves money.”
If you would like to visit our new testing laboratory, or would like to discuss any glass container issues with us, please contact Peter de Haan at our Delft Lab at: +31 (0)15 890 40 20, or Contact Us.

We are pleased to announce...
Dr. Clarissa Justino de Lima has joined the AGR Testing Laboratory team in Delft, the Netherlands as a Senior Scientist. "We have continually expanded our staff to meet our growing needs and are pleased Clarissa is joining us and bringing a wealth of experience" said Peter de Haan, Senior Scientist and Manager of the Delft lab. Clarissa’s main areas of responsibility will include fracture analysis, container testing as well as seminar instruction.
She will also have considerable involvement with the internal research projects and technical papers as they relate to glass as a material for use in the container industry.   Clarissa received her PhD in Civil Engineering from Technische University Delft.  She also holds a Master’s degree in Science & Engineering of Materials from Federal University Alfenas in Brazil.

AGR releases new Proof of Design Report

The ability to predict and verify the performance of a container, well in advance of mold creation, is invaluable. The AGR Proof of Design service helps our customers streamline project schedules and delivers confident product launches. We are pleased to announce an upgrade to this trusted service with the introduction of our enhanced Proof of Design report format. The enhanced format provides key testing data and conclusions at a glance. With contemporary, tailored figures and tables which allow our customers to quickly make data-driven decisions.

Of course, we still include the key value-add benefit that differentiates us from other testing. We don’t just report the data. Leveraging our fracture analysis expertise we analyze low strength failures and indicate the cause and the corrections necessary to achieve acceptable quality and performance.

The Proof of Design services provides customers with assurances that their production quality and container design are world-class.  “Ultimately, the goal for glass packaging is to prevent breakage and enable our customers to fill with confidence”, said Dr. Wenke Hu, AGR Senior Scientist. “Whether it is a lightweighting project, new product development or a desire to increase filling line speeds, a sound bottle design with high quality glass production is imperative for success. We feel our service gives our customers the best chance to achieve those goals”, said Hu.

AGR developed and began offering the enhanced report in Q1 of this year. To date, customer response to the clear and comprehensive tables and supporting color coded graphics has been overwhelmingly positive. The new format simply communicates the key points more efficiently.

Q: Is glass strength primarily dependent on glass thickness?

A: No. It is important to note that the strength of glass is defined as the stress at failure. Strength of glass is not a material property, but rather, it depends on the flaws present in the glass surface. While thickness can dictate the amount of stress a glass article can endure, it has nothing to do with the surface strength.

The strength of glass is determined by:

  • Surface condition (flaws present)
  • Water Vapor
  • Time (Static fatigue - duration of stress)

Did you know …

that all batch materials need to be analyzed, including cullet and electrostatic precipitator dusts, to assure all materials being fed into the furnace are reliably of the composition used in the batch calculation? These analyses are critical in order to achieve the desired final glass composition.

Second half training schedule finalized
The second half training seminar schedule has been finalized and gets underway in picturesque Lake Ammersee, located just outside Munich, Germany starting with “Fracture 1: Testing and Breakage Diagnosis of Glass Containers” September 9-11 followed at the same location by “Evaluation and Lightweighting of Glass Container Designs” September 12-13. These back-to-back seminars allow participants to attend both minimizing travel.  Due to the popularity of Fracture 1, a second seminar has been added in Lake Ammersee September 16-18.
We will also be conducting F1 on our Butler, PA, USA campus September 17-20. The Fracture Diagnosis of  Pharmaceutical Glassware seminar takes place September 10-12 and is also on our Butler campus.
Krakow, Poland hosts:
  • Fracture 2: Advanced Breakage Diagnosis Oct 1-4
  • Glass container Technology Oct 7-8
  • Fracture 1 Oct 9-11
These additional seminars will be held on our Butler Campus:
  • Cord and Annealing Oct 8-9
  • Glass Container Technology Oct 10-11
  • Fracture 2: Advanced Breakage Diagnosis Nov 5-8
  • Coating Technology Nov 19-20
  • Bottle Design Evaluation/Lightweighting Nov 21-22
Moscow, Russia has been added to our Training schedule and will be hosting Glass Container Technology Oct 21-22 and Fracture 1 Oct 23-25.
