Sand Cores

Arena-flow is used to simulate the filling of an automotive cylinder head water jacket core through an integrated core print.

Arena-flow, by CPFD, models the air-driven sand flow critical to the creation of consistent, high-quality sand cores and molds for many processes including cold-box, shell, inorganics, greensand, hot-box, and warm-box. This video illustrates how air flow drags sand into the cavity.

This video shows how a mixture of gas and air progresses inside a core box, as the sand has contact with gas, air, cured sand, in this instance cured sand is shown as transparent dark grey.

This video demonstrates Arena-flow’s inorganic curing capabilities for dehydrative systems.

This video demonstrates the air-sand motion computed by Arena-flow for a magazine used to fill multiple sand cores.  As the magazine pressurizes, the air drags sand into the core.

This video shows the cope and drag views of a thin-walled jacket core made using the shell sand / warm box module of Arena-flow.

Arena-flow by CPFD Software simulates the blowing of industrial sand cores, and this video highlights a cold box core scenario of a cylinder head water jacket.

This video demonstrates the validation of Arena-flow’s cold box curing model using transparent tooling.
