Verification and tests within polymer materials, design and processing

20 September 2022

Scandic Odense
Hvidkærvej 25
5250 Odense

Test and verification is costly both in time and money. It is important to test enough to verify your products. However testing too much is expensive and can prolong your time-to-market.

On this day we will take a look at how test and verification can be done effectively. The performance of plastic materials is often highly dependent on manufacturing process parameters. We will see how the processing parameters will influence the performance of the final part.

Who can participate
The program is targeted persons who work with product development. It could be within design, test, quality control or many other functions.

This seminar has been developed by Kristian Meldgaard, Peter Sommer-Larsen and Ion Marius Sivebæk from ATV-SEMAPP’s steering group for plast technology.

Verification and tests - what kind of evidence do you need?

Carsten Lund, Owner, EpsilonPlus

Testing, verification and even validation is common during development, but what is the difference between these terms, and what does it mean for your analysis? There is one common factor and that is the purpose. In addition you have questions where you need a yes/no answer.
The challenge is that you can never be 100% sure about the conclusion because in theory it could be pure luck that the test went well. You may test more products to be certain, but how many do you need to test? My question is how much evidence do you need? I hope to try to give you at least part of the answer.

Carsten Lund is the owner of EpsilonPlus supporting customers with quality management, injection moulding expertise and statistical analysis. He has a mechanical engineering background and is specialized in injection moulding. He is also a Six Sigma black belt and has been helping companies across Europe with process validation for more than a decade at EpsilonPlus.

CT-scanning in medical device development

Jan Andreasen, Senior R&D Engineer, Novo Nordisk A/S

In medical device development design loops with physical prototypes are a part of the process to reach the design intend. We have over the past 15 years been using CT-scanning comprehensively in the development process for prototype characterization. That is for moulded part verification and for troubleshooting functional challenges and failure investigations in device testing. This presentation will through examples demonstrate opportunities, limitations, and give you recommendations for using this characterisation tool in test and verification.

Jan Lasson Andreasen is Senior R&D Engineer at Novo Nordisk A/S, where he has been working with test and characterisation in device development since 2005. He holds an industrial PhD in surface characterisation from DTU / Brüel & Kjær A/S. He has more than 40 scientific and technical publications.

Assessing material and process variations for high quality moulded elements

Kelly Briceno, Material Platform Manager, Lego

The creative process of building LEGO models is only possible with high precision interlocking LEGO elements. This has been the case for more than 60 years. Due to the LEGO Planet Promise and the ambition of introducing new sustainable materials it is necessary to explore a wider range of materials.
This presentation aims to show the main technical consideration to guaranty the high level quality of LEGO products no matter the type of resin, colors, suppliers and element design required for the near future. In this work, the processing parameter influence on shrinkage and crystallinity was studied in a DoE. Furthermore, the influence of colours was also investigated.

Kelly Briceno is a Materials Engineer and have been working for more than 15 years with different materials accross Europe. Since 2019, she has been dedicated to research, understanding and supporting the implementation of more sustainable materials in the LEGO portfolio.

Assessing material and process variations for high quality moulded elements (continued)

Wendi Wang, Moulding Technology Manager, Lego

Wendi Wang is moulding technology specialist at the LEGO group. With a background in polymer physics, she is interested in understanding the link between process variables and material properties through a scientific data-drive approach.

How to optimize development and verification of injection moulded parts

Anders Johnsen, VP – R&D and Technology, Carmo A/S

Development and verification of devices containing injection moulded parts are traditional time consuming and highly expensive. This presentation will show ways to optimize the development process – time to market with examples and ideas taking into consideration the environmental footprint too.

Anders Johnsen is heading the R&D department at Carmo A/S. He has a mechanical engineering background and is specialized within advanced injection moulding, focusing on components for medical devices.

Using screening analysis tests of critical components before large-scale application testing

Arnim Saalbrink, Senior Specialist – polymer materials and processes, Danfoss

Products are usually tested in large-scale, time-consuming tests under application conditions before introduction to the market. To avoid costly retests at this stage it is desirable to identify the products critical components and screen these for potential problems with regard to the foreseen application conditions. The presentation will show some examples where such screening analysis tests revealed problems relating to polymer materials and processing, and helped to avoid costly retests.

Arnim Saalbrink is Senior Specialist for polymer materials and processes at Danfoss A/S Technology Centre. He has a chemical engineering background (M.Sc.) and worked with plastic- and rubber materials analysis, testing and selection in various research- and industry positions in The Netherlands and Denmark.

Diffusion and permeation in polymers, measurement, and application

Jakob S. Engbæk, Senior Specialist, Civil Engineer, Ph.D., Danish Tecnological Institute

Diffusion of gases and liquids in polymers is relevant for many applications of polymers. Permeation through the material is important for the barrier properties in use with pipes, gas containers and packaging of foods and pharmaceutical products. It is also important for pressure transducers and pumps where seals are influenced. Measuring permeation as a function of time gives a measurement of solubility and diffusivity in the polymer. After touching the theory, methods for measuring and some results will be shared along with some unusual applications illustrating pitfalls for hermetically sealed products.

Ph.D. from DTU, has worked with development projects and measurements of permeability at the Danish Technological Institute since 2006.

Recycled plastic

Peter Sommer-Larsen, Business Manager – Plastics and Packaging Technology, Danish Tecnological Institute

Performance? Quality assurance? Supply? Recycled content? Additives? Marketing? The use of recycled plastics poses many questions for verifications and quality assurance, that normally is handled by the polymer supplier when it comes to virgin polymers. The tools for dealing with some of these questions are built in norms, standards, regulations, and directives. One example is the proposal on updates to “recycled plastic materials and articles intended to come into contact with foods, and repealing Regulation (EC) No 282/2008”. Here, it is proposed that each batch of recycled plastics to be used in food packaging should come with a declaration of conformity.

We will look into these complex questions in the talk – honestly, we don’t give a solution manual, but we hope to spawn a dialogue and get feedback from the participants.

Peter Sommer-Larsen is Senior Specialist and Business Manager at the Danish Technological Institutes’ center for Plastics and Packaging Technology. His business area is conversion technologies for plastics and process development with a particular emphasis on recycling and sustainability of plastic products.
