DEFECTS DURING EXTRUSION PROCESSES -RECOGNIZE, ANALYZE, GRADUATE AND ERADICATE

摘要

Cutbacks, off-shoring and other cost reduction processes have led to a major loss of internal company know-how. Inefficient product and process qualities result primarily from non-aligned parameters, which are influenced by the operator. In the context of a research project conducted in collaboration with partners in industry, recognition features are established for defects in pipe extrusion lines. Products and processes can be analyzed, and defects graduated in process models, which put forward a catalog of potential measures on the basis of a self-compiled database. Reasonable variables for optimizing the products are identified, which means that defects can be eliminated by remaining within prescribed boundaries. The results are made available to all comparable production lines and validated.
