Satisfied customers are at the heart of every successful company. They are not only a sign of excellent service quality and outstanding products, but also act as ambassadors for the brand. Through recommendations or positive reviews, they make a significant contribution to the growth and reputation of a company.

In the following, we would like to present some examples of our work.

Project examples

Development of a new type of compound for the extrusion of profiles

The aim of the project was to develop a compound that was reinforced with natural fibers instead of glass fibers. A profile is then to be extruded from the compound. The project went through the following steps/phases:

Application qualification of an additive and derivation of recommendations for action for the plastics processing industry

The aim of the project was to qualify a plastic additive for various applications in plastics processing. As a result of the project, not only were the engineering effects that occurred when the additive was used in the end product measured, but specific recommendations for action were documented for the end users of the additive (our customer's customers) and implemented in an easy-to-understand marketing flyer. The project went through the following steps/phases:

  • Markt- und Patentüberblick
  • Technische Machbarkeitsprüfung anhand der entwickelten Ideen (à Entscheidung des Kunden das Projekt mit unseren Lösungsansätzen fortzusetzen)
  • Compoundieren von Testserien mit einem ausgewählten Biokunststoff als Matrix, verschiedenen Anteilen der vom Kunden bereitgestellten Naturfaser sowie verschiedenen Anteilen eines recherchierten natürlichen Faser-Matrix-Kopplers zur Realisierung einer ausreichenden Faser-Matrix-Anbindung
  • Test der Faser-Matrix-Anbindung sowie Analyse der erzielten Homogenität der Faserverteilung und Test der vom Kunden als relevant eingestuften Eigenschaften wie E-Modul, Zugfestigkeit, Bruchzähigkeit
  • Optimierung in Schritt 4 entwickelten Compounds hinsichtlich Zusammensetzung und Verarbeitbarkeit (Minimierung der kostenintensiven Rezepturbestandteile und Minimierung des Energieaufwands während der Compoundierung durch Optimierung der Rezeptur und Nutzung von Additiven zur Verbesserung beispielsweise der Fließfähigkeit des Matrixkunststoffs und Dispergierung der Fasern)
  • Herstellung von Profilen auf Technikumsebene (Prototyp)
  • Erstellung eines Datenblatts zum in Schritt 6 hergestellten Datenblatts und Übergabe sämtlicher Ergebnisse und Muster an den Kunden
  • Erstellen eines Versuchsplans (im Einzelnen wurden Mischungsreihen verschiedener Matrixpolymere mit unterschiedlichen Anteilen des betreffenden Additivs realisiert. Zur besseren Ver- und Zerteilung des Additivs im Prozess wurden im Vorfeld Compounds aus Matrix und Additiv in den unterschiedlichen Mischungen hergestellt.)
  • Analyse der Qualität der Compounds hinsichtlich Additivverteilung und Rieselfähigkeit des Granulats
  • Herstellen von Mustern unter Zuhilfenahme von Kunststoffverarbeitungsverfahren auf Technikumsebene (Extrusion, Spritzguss, Thermoformen und 3D-Druck)
  • Allgemeine analytische Untersuchungen zur Verarbeitbarkeit der Compounds und Test der vom Kunden als relevant eingestuften Eigenschaften wie E-Modul, Zugfestigkeit, Bruchzähigkeit, MFI sowie weitere Eigenschaften, die das Additiv positiv beeinflussen soll
  • Dokumentation der Ergebnisse in Form eines Prüfberichts und Erstellen eines Flyers mit konkreten Handlungsempfehlungen (Der Flyer wurde speziell für VertriebsmitarbeiterInnen erstellt, die dann wiederum bei ihrem Kunden die Benefits des zu verkaufenden Additivs klar und unkompliziert kommunizieren können.)
  • Zusammentragen der Anforderungen, die an das betreffende Produkt des Kunden gestellt werden
  • Übertragen der Anforderungen in messbare ingenieurtechnische Größen. Definieren von Mindestanforderungen bezogen auf die ingenieurtechnischen Größen
  • Prüfung eines Benchmarks im ungealterten Zustand und Prüfung real gealterter Produkte bekannter Einsatzdauer durch Messen bzw. Ermitteln der unter 2) festgelegten ingenieurtechnischen Größen in Abhängigkeit der Alterungszeit mit dem Ziel eine Masterkurve bzw. einen Masterkurvenbereich (+/- 5% der Werte der Masterkurve) zu erstellen. Kennzeichnen der unter 2) definierten Mindestanforderungen in der Masterkurve zur Visualisierung des vom Kunden noch akzeptierten Produkteigenschaftsniveaus
  • Eine fortlaufende Prüfung bzw. Einsatzqualifizierung der Kundenprodukte ist möglich und erhöht nach und nach die Genauigkeit der Masterkurve bzw. des Masterkurvenbereichs. Weiterhin kann anhand der aufgestellten Korrelation auch zu unbekannten Alterungszeiten hin inter- oder extrapoliert und somit eine Lebensdauerabschätzung vorgenommen werden.
  • Dokumentation der Ergebnisse in Form eines Prüfberichts
  • Market and patent overview
  • Technical feasibility check based on the ideas developed (à customer's decision to continue the project with our solutions)
  • Compounding of test series with a selected bioplastic as matrix, different proportions of the natural fiber provided by the customer and different proportions of a researched natural fiber-matrix coupler to achieve a sufficient fiber-matrix bond
  • Test of the fiber-matrix bond and analysis of the homogeneity of the fiber distribution achieved and test of the properties classified as relevant by the customer, such as modulus of elasticity, tensile strength, fracture toughness
  • Optimization of compounds developed in step 4 with regard to composition and processability (minimization of cost-intensive formulation components and minimization of energy consumption during compounding by optimizing the formulation and using additives to improve, for example, the flowability of the matrix plastic and dispersion of the fibres)
  • Production of profiles at pilot plant level (prototype)
  • Creation of a data sheet for the data sheet produced in step 6 and handover of all results and samples to the customer
  • Creation of a test plan (in detail, series of mixtures of different matrix polymers with different proportions of the additive in question were realized. Compounds of matrix and additive in the different mixtures were produced in advance to improve the distribution and separation of the additive in the process).
  • Analysis of the quality of the compounds with regard to additive distribution and flowability of the granulate
  • Production of samples with the aid of plastics processing methods at pilot plant level (extrusion, injection molding, thermoforming and 3D printing)
  • General analytical studies on the processability of the compounds and testing of the properties classified as relevant by the customer, such as modulus of elasticity, tensile strength, fracture toughness, MFI and other properties that the additive should positively influence
  • Documentation of the results in the form of a test report and creation of a flyer with specific recommendations for action (the flyer was created especially for sales staff, who in turn can then communicate the benefits of the additive to be sold to their customers in a clear and uncomplicated manner).
  • Compilation of the requirements placed on the customer's product in question
  • Transferring the requirements into measurable engineering parameters. Defining minimum requirements in relation to engineering parameters
  • Testing of a benchmark in an unaged state and testing of real aged products of known service life by measuring or determining the engineering variables defined under 2) as a function of the ageing time with the aim of creating a master curve or a master curve range (+/- 5% of the values of the master curve). Marking of the minimum requirements defined under 2) in the master curve to visualize the product property level still accepted by the customer
  • Continuous testing or application qualification of customer products is possible and gradually increases the accuracy of the master curve or master curve range. Furthermore, the established correlation can also be used to interpolate or extrapolate to unknown ageing times and thus estimate the service life.
  • Documentation of the results in the form of a test report
