Join us in our two private groups: GFS - Gietech Foundry Society and GIC - Gietech Improvement Center. These groups are for the members only and cannot be entered by others. Take the benefit of introducing problems and or questions and get the answers from the other groups members. For delicate questions, you can ask the groups owner (Staf Henderieckx) to enter them under his name. Sharing knowledge and experience is the best way to grow... Send me your request to join.
