Asahi Breweries Europe values benefits from partnership with AGR

In December 2017, Kompania Piwowarska SA (the subsidiary of Asahi in Poland) requested AGR investigate breakage rates in the filling line concerning non-returnable glass bottles. Based on the detailed description of the problem, technical drawings and breakage samples provided by Asahi, AGR performed a comprehensive analysis to identify the root cause(s) for  the witnessed breakage, involving:
  • Fracture Analysis
  • Finite Element Analysis of the Bottle Design
  • Comprehensive Audit of the Filling Line
 A number of issues were identified concerning the manufacturing quality of the supplied bottles and the filling line handling. Major aspects involved:
  • the vertical glass thickness distribution differed significantly from the design criteria – thus pointing to issues traced back to the bottle supplier,
  • excessive impact forces were observed in the packaging end of the filling line, which resulted in bottle breakage inside the cardboard cases. Detailed recommendations were given to improve the palletizing machine.
 The value of the project delivered in partnership with AGR consisted not only in a reduction of line losses (bottles and beer), but more importantly, in an efficient and accurate diagnosis of the root causes of the problem, which prevented time-consuming and potentially misleading investigations and hypotheses. End-to-end assistance provided by AGR allowed for a quick and accurate identification of the key issues involved, which made it possible to take the proper corrective actions consisting of a redesign of the bottle leading to an increase of its impact resistance and changes to the filling line machines.
This all was made possible due to a multi-disciplined approach to the problem, clear and effective communication between AGR and Kompania Piwowarska, the audit methodology based on scientifically proven concepts, and an end-to-end service including the redesign and validation of the non-returnable beer bottle.
Thank you and looking forward to our further work together!

AGR will be attending the glasstec trade show in Dusseldorf, Germany October 23-26. AGR Director of Research, Bill Slusser along with Manager of Research Services-Europe, Peter de Haan,will be available to discuss any glass issues you may be experiencing.

 AGR will also be offering a Free Training Seminar at glasstec entitled "The 3 Key Stages of Glass Container Development". The seminar details the fully immersive product development service offered by AGR. The topics will  include filling line auditing, enhanced conceptual design creation, physical testing and manufacturing auditing.

If you would like to set up a meeting with Bill Slusser or Peter de Haan Contact Us .   While at glasstec please visit us at stand 14/C28

AGR will be attending the 79th Glass Problems Conference November 5-8 in Columbus, Ohio. The GPC is the largest glass manufacturing conference in North America, attracting glass manufacturers and suppliers from around the world, allowing an open exchange of innovations and solutions.

AGR has been a regular participant at the conference as both speakers and exhibitors throughout the history of the event.  AGR will be represented by Senior Scientist Dr. Brandon Aldinger, Research Engineer Brian Collins, and AGR Manager of Analytical Services Neal Nichols.

Q: Are stresses created by cord, annealing and ACL permanent throughout the lifetime of the bottle?

A: Yes, these three types of stress are permanent. Although they are rarely high enough to cause breakage on their own, they can combine with stresses generated by other loads on the container. The combined stresses can potentially lead to failures when the magnitude exceeds the container’s strength. Thus, ensuring that the cord, annealing, and ACL stresses are acceptable is a critical aspect of container performance success.  

This question is asked frequently and has become part of our "Glass Myths - Fact or Fiction" section of our "Fracture1: Testing and Breakage Diagnosis of Glass Containers" Training Seminar that addresses many glass myths.

2019 Training Seminar Schedule Announced

Do you want to learn how to diagnose and prevent bottle breakage?  Conduct a thorough audit of a glass manufacturing plant? Or understand all of the implications of Lightweighting a bottle design? 

AGR Training Seminars can help in all these areas and will be held in the first half of the year in Krakow, Poland, Munich, Germany, Moscow, Russia, Butler, PA and Montecchio, Italy. 

Here is our first quarter schedule:

February 12-15 Krakow: Fracture 3: Glass Fracture Diagnostician
February 18-19 Krakow: Evaluation and Lightweighting of Glass Container Designs
February 20-21 Krakow: Audit of Glass Plant Operations

March 19-22 Munich: Fracture 2: Advanced Breakage Diagnosis of Glass Containers
March 25-27 Munich: Fracture1: Testing and Breakage Diagnosis of Glass Containers

See our Training Schedule for the dates and locations of all of our seminars and our Training Catalogue for descriptions of all of our seminars.
