Experience indicates that joining plastic materials can be a challenging discipline, and our plastics laboratory has expertise with various methods for quality assurance of plastic products containing joints.

Quality assurance includes, among other things, regular inspections, damage analysis, or advice on joining, e.g., laser weldability. With various scanning techniques, we detect voids and other defects in the interface layer.

Testing can be performed according to internationally recognized methods such as ASTM F88 or in customer-specific setups.

What can the Danish Technological Institute help you with?

  • We document adhesion (possibly before and after aging according to ISO 6133)
  • We examine the usability of peel-open packaging
  • We test adhesive strength – also at high and low temperatures
  • Laser welding, compatibility of plastic materials
  • Advice on joining plastic materials and pre-treatment
  • Detection of changes – comparison of ‘good’ and ‘bad’ joints
