Indirect extrusion (backward extrusion) is one of the keystone technologies used by GoldEx. We have invested heavily into these systems and now have four indirect extrusion production lines in our workshop. They are equipped with a gas injection fast preheating furnace, hot skinning machine, continuous infrared temperature measurement system, water and gas combined quench, etc. Using this equipment, and we are able to extrude 17 tons materials per day.
