Murray, Hoosier Pattern: Tools will


last forever and storage is free. T e truth is much diff erent. Old wood patterns and coreboxes dry out and degrade. Iron will rust and corrode. Regarding stor- age, there is a cost to bring tooling out of storage after many years and getting it ready for production.


What’s one unexpected benefi t for


a metalcasting facility to outsource its production of patterns and tooling?


Murray, Hoosier Pattern: Speed.


Metalcasters should work with pattern shops to choose the best material and process for the intended casting.


remounting and core box maintenance should all be fairly predictable. Try to eliminate surprises in that regard. Lamoncha, Humtown Products:


In terms of the supply chain, you really have to look at a pattern shop like a partner and not just a supplier. In the end, the goal is to make the end


customer happy. If a tool shows up and it’s not working as expected, it’s easy to start pointing fi ngers and that’s counterproductive.


What’s a common misconception you


encounter regarding tooling ownership and/or storage?

• Reduce prototyping costs • Achieve superior hydraulic balance


If you can outsource a part when it makes sense, you can use the tech- nologies off ered by the pattern shop without owning the machinery. Lamoncha, Humtown Products:


You gain a lot of knowledge working with a pattern shop that builds tooling for all diff erent industries. I’ve built 30-40 tools in the last few months in all diff erent industries, so I have a diff erent way of looking at a particular corebox or casting.
