MAXImolding - vertical injection molding machine with partially liquid melt
The same principle has been used for casting for more than 5,000 years. The metal is heated in a pot so that it becomes a liquid. Then it is dosed into the mold with a spoon, where it then solidifies.
The time is ripe for a new process, a new machine, and a green, smart foundry. The aim is to solve two problems: the fast production of almost defect-free light metal parts with high integrity and the avoidance of emission of dangerous gases into the atmosphere. The aim is to improve the currently unsustainable approach in a foundry, according to which the liquid melt is produced under cover gases, is then poured into a mold, parts are inspected, separated in good and bad, and bad parts are finally remelted.
After 10 years of basic process development and 15 years of continuous machine improvement, the MAXImolding machine was created. This is a further development of the Thixomolding® machine without an extruder, which also combines the advantages of hot and cold chamber HPDC machines and avoids their disadvantages. This is a vertically oriented, environmentally friendly metal injection molding machine for semi-solid light metal melt. The melt is produced internally with 70% less energy compared to cold chamber machine and without dangerous gases. The partially liquid melt is precisely dosed under the injection piston and injected with 50% less material compared to cold chamber machines. It is injected directly with great force and speed into a mold of a hydraulic lower piston press. The MAXImolding machine was initially developed for magnesium alloys, but a modification for aluminum alloys is planned.
The exact principle of the MAXImolding technology was explained in the magazine CASTING PLANT & TECHNOLOGY 2/2021.
