An innovative manufacturing process
The ProMetal RCT technology features:
* Industry proven casting materials.
* Online mixing of sand and hardener: No premixing and no reservoir refills required.
* Additive manufacturing of molds and cores.
* Proven printing technology for precise dosing of the binding agent.
* No support structures needed.
* No specialized postprocessing required (besides cleaning).
* Finished parts are generally available immediately for casting.
* Capable of complex internal details and structures, otherwise unattainable by traditional methods.
The molds and cores are built in a layered fashion. The same building principle is used with the metal process (click here for more information)
Each layer is comprised of two materials added sequentially:
A recoater applies the pre-mixed molding sand onto the entire building platform.
The printhead selectively dispenses the resin in the sand.
The activator contained in the sand hardens the binder and realizes the object, one layer at a time,
Selectively dispense binder using inkjet printing technology.
The build platform is lowered by a set increment.
Spreads a new layer of pre-mixed quartz sand.
Repeat step 1-3, until the mold or core is built.
Unbound sand is removed. Metal parts are cast.
