Master thesis Polymer Engineering (m/w)

ALPLA Werke Alwin Lehner GmbH & Co KG / Hard / Austria / Technical Support

Your responsibilities

  • ALPLA, one of the biggest rigid plastic packaging manufacturing companies in the world, uses ISBM (Injection Stretch Blow Molding) technology to manufacture PET bottles for different applications.
  • One of the largest market segments is the beverages industry for carbonated soft drinks.
  • Due to the competitive market, which drives light weighting of the bottles, and the extreme climate conditions in Mexico, environmental stress cracking (ESC) has become a quality issue.
  • In previous studies, residual stresses have been identified as one of the dominant factors. Thus, the objective of this master thesis is to develop a measurement method for stress distribution and symmetry in PET bottle bases with polarized light.
  • As ESC normally does not have its root cause in one single factor, the different variables and their combinations have to be analyzed using a Design of Experiments (DoE) approach.
  • For this topic we're looking for an interested student to write his/her master thesis on a 6 month basis. During this time some of the experiments will be done in Mexico in an ALPLA Plant.

Your competencies and qualifications

  • Student currently doing his/her Master in a technical field (Polymer Engineering or Material Science)
  • Strong communication and intercultural behavioural skills
  • Solution thinking and independent working skills
  • Excellent English and German language skills, Spanish skills would be also helpful

Our offer

  • Modern family based work environment
