© IKVTopic of the work:
The factors influencing the bond strength must be characterized for the use of micro-molded plastic/metal components.
The work is related to this research project:
In the IGF project “MiFoVe”, IKV is working on the investigation of hybrid components to facilitate their use in industrial products. As part of your work, you will have the opportunity to coordinate closely with industrial companies.
Objective:
The bond strength of a micro-form-fit bond between plastic and a joining partner is largely determined by the molding compound used, the injection molding process, the structural arrangement, the structural geometry and the load case. The structure opening width, the undercut of the structure and the structure depth play a particularly important role in the structure geometry. The structural filling also influences the bond strength. Through a holistic and systematic consideration of the influencing factors described, a design guideline is developed that facilitates the design of micro-form-fit joints, adapted to the load case of the application and the plastic used, and thus enables the economical development of hybrid, micro-form-fit joined components.
