Hi World!!
Let me introduce myself, I am a chemical engineer from Spain.
Although I have focused my professional career in injection plastic molding. Studying several master degrees in injection molding process and design of injection molds.
Moreover, I have worked in three of the biggest company in injection molding and I have travelled around the world, in the development and set up for new tools.
I love to help and teach people, that it is the reason why I am here.
