Core Making

Sand Core Engineering

Core making can be challenging. Both sand and air flow, within the tooling, are essential for making a good core. Arena-flow is not just a process model, but rather a fundamental approach to computing the sand flow and air flow physics of core making. Thus, it is not applicable to only one process, but has been successfully applied to a variety of core making technologies. Learn how you can apply the Arena-flow Sand Core Engineering Technology for your process:

Cold-Box

If you're utilizing a cold-box process, you're probably very interested in productivity. Arena-flow has interfaces specifically designed to enable the cold-box foundry to optimize their processes resulting in minimal scrap, binder loadings, amine or SO2 usage and cycle times. Cold-box sand core engineering physical models include:

air flow modeling
transient amine curing
transient SO2 curing
core fill and miss-fill prediction
core density variations
tool wear prediction
resin wipe-off prediction
sand particle size distribution
multiple sand types, and mixtures
sand flowability (binder effects)
discrete vent models
magazine performance and rat-holing

Shell Sand

If you're a shell foundry, then you probably have other concerns. Shell tooling is different than cold-box tooling. Venting may be limited, and the air flow in hot shell tooling is vital to ensuring complete and uniform core filling behavior before the sand begins to harden. Shell sand core engineering physical models include:

transient air flow during core filling
sand particle size distribution
multiple sand species
core fill and miss-fill
core density variations
tool wear prediction
sand flowability
discrete vent models including: circular vents, slit vents, parting line venting, vent clogging, etc.

Warm-box, Hot-box, Inorganics, ...

Arena-flow has been used to simulate, understand and optimize a variety of other core making processes. While the flowability or "stickiness" of these binder systems can differ, Arena-flow includes a custom flowability model which enables you to compute the complex, core-filling behavior. Advanced sand core engineering physical models include:

transient air flow during core filling
sand particle size distribution
multiple sand types and mixtures
tool wear prediction
resin wipe-off prediction
custom sand flowability
discrete vent models
magazine performance and rat-holing

Tooling Design

Arena-flow is not just useful to foundries, but also for tooling suppliers. If you are a tooling vendor, then you likely design and manufacture tooling for a variety of customers employing a variety of core making processes. At the same time, your customers are probably asking you to take on an increasing level of design responsibility, as they have reduced their internal expertise over the past few years. All of the above sand core engineering physical models are available to tooling suppliers. Tooling suppliers, however, typically have different reasons for running Arena-flow calculations. These include:

meeting or exceeding OEM requirements
eliminating trial-and-error in the design process
creating a good core on the first blow
designing optimized tooling
designing long-lasting tooling with minimal wear
differentiating themselves from the competition
