Our Products


FastCore technology is used by ACM to make net shape mandrels for customers. These mandrels are delivered pre-formed and sealed with PTFE tape. They arrive at your facility as a ready to use shop supply. FastCore technology is suitable for rapid prototyping and production quantities.

AquaPour is a fluid slurry that is castable; hence, it is capable of forming complex shapes. It comes as a dry powder and water is added to activate it. It is most commonly utilized in applications where a mold is filled with the material in the liquid state, and upon setting in the green state.

ClaveCore is a patented self-pressurizing tooling material. It is rigid at room temperature, but becomes an expanding semi-liquid at high temperature. It is designed for out of autoclave applications that are OML driven. Its pressurization behavior can be engineered via composition to control the pressure onset temperature and magnitude of pressure.

Aquacore Premium

AquaCore™ Premium contains all of the advantages and properties of AquaCore™ but features a higher compressive strength.

Learn More


Aquafill™ has been formulated to patch the water-soluble mandrel materials Aquapour™, Aquacore™, and Aquacore™ Premium. Aquafill™ is premixed and ready to use. Once the mandrel has been formed and dried in a convection oven, it can be applied easily with a rubber squeegee such as those used in auto body applications.

RTM Core technology is the 1st soluble tooling system designed for resin infusion processes. Its unique properties allow it to be formed with heat and pressure (no drying required!). It is available in block form and can be machined or sanded to a smooth surface finish.

Learn More


The FastPour mandrel technology allows water soluble mandrels to be formed on-site. FastPour technology uses a unique binder system that provides rapid strength development, rapid set times, and a wide range of operational temperatures (up to 750-800°F).
