With all of the attention to Additive Manufacturing, you would think that traditional manufacturing methods have lost their place in today’s production. But that is hardly the case as current manufacturing equipment and automated processes are still king and dominate the vast majority of castings made globally, today.
Production volume projections, delivery requirements, and costs are all important consideration in determining the correct production methods for your parts.
Recently, Cunningham Precision produced a new pattern and core box for the production of complex engine parts in 6 days – cheaper and faster than 3D printing.
A major engine manufacturer was having difficulty getting castings produced quickly enough from their production foundries. Not being able to ship their engines on-time was costing them millions of dollars.
To meet their shipping requirements, we produced new tooling and cast their engine parts. Their shipment requirements were varied from 12 castings on one part and up to 300 castings on another part per shipment.
4-cavity cope/drag pattern from urethane tooling board and a 2-cavity urethane core box. This pattern is estimated to last up to 2000 molds.
If you were to 3D print this same project (print both the cores and mold) The costs would be $1900 for one sand mold with cores. In other words, making more than 3.5 molds would exceed the pricing of the tooling!
In 6 days patterns, core boxes were produced, sample molds were poured, P.P.A.P. was completed, samples shipped to customer, and remaining molds were poured and all castings completed (150 casting total).
Cost savings are estimated at $60,000 versus their in-house 3D printing facility.
