Autocaster Continuous Casting Systems

Ultra CM325

The ultimate technology available for high throughput continuous casting!

Application: Automated, continuous casting for cast polymer and other composites manufacturing.


The Autocaster Ultra™ continuous casting machine and associated Ground Hoppers automate filler loading, recipe management, mixing and dispensing of cultured marble matrix for cast polymer manufacturing for unparalleled continuous casting production.
Replacing manual mixing and casting with the Autocaster Ultra™ will significantly increase productivity, cut material cost and improve quality – all leading to increased profits for the manufacturer.
