Elastomer covers all types of Rubber, of which I have personal experience with Natural Rubber, Silicone, FKM, Neoprene, and Polyurethane
Each material has different characteristics and forms in different ways, I personally have formed rubber through Extrusion, Injection, and Blow Molding but have the most experience with Compression of which I have developed industry-leading tooling and automation methods for
I have also built a facility for specifically FKM Forming which utilized 100K clean rooms and silo process management and quality systems to ensure efficient production
Colored rubber, especially FKM has a high defect rate (especially white components) and possible quality defects from contamination, short shot, flash or shiny marks caused by heating issues can all occur very easily without understanding and designing to mitigate these issues the product can become unviable
