Interactive workshop: Creation of working groups to study and analyse physical samples
– Viewing and describing defects in real samples
– Study of their problems
– Discussion of possible solutions
– Possibility to bring own parts with defects for assessment
– Conclusions of the workshop
To delve into the causes and solutions of most of the defects in a plastic injection moulded part. Questions will be answered such as: What is the real source of the problem? Is it in the injection moulding machine? Is it in the mould? Is it a design problem? Is it the material? Is it the process parameters?
Technicians and professionals in the plastic injection sector, both transformers and consumers of plastic parts (automotive, packaging, medicine, etc.); mainly in the Production, Finishing, Development, Quality and Sales Departments.
