Scientific papers database

Ortofon has an extensive global network of technology partners with whom we exchange information, troubleshoot, research and write research papers summarizing findings, methods and results

Scientific collaboration

In Ortofon research and development is done with the company's own engineers supported by a strong network of technological know-how.
In recent years Ortofon A/S and Technical University of Denamrk have been working in close collaboration to develop the micro-factory concept with the objective to develop and optimize the manufacturing process for the mass production of multi-material functional micro-components. Micro injection molding (μIM) is one of the most suitable micro manufacturing processes for flexible mass-production of multi-material functional micro components.

Micro-injection moulding process simulations can be important to substantially reduce experimental and quality assurance efforts. In this study, the usage of process simulations for the prediction of the size of the flash affecting a three-dimensional polyoxymethylene (POM) micro component is discussed.

Micro-Injection Moulding In-Line Quality Assurance Based on Product and Process Fingerprints

Department of Mechanical Engineering, Technical University of Denmark, Lyngby, Denmark

Micro-injection moulding (μIM) is a replication-based process enabling the cost-effective production of complex and net-shaped miniaturized plastic components. The micro-scaled size of such parts poses great challenges in assessing their dimensional quality and often leads to time-consuming and unprofitable off-line measurement procedures. In this work, the authors proposed a novel method to verify the quality of a three-dimensional micro moulded component (nominal volume equal to 0.07 mm3) based on the combination of optical micro metrology and injection moulding process monitoring.
