On the Metal Casting Design and Purchasing LinkedIn discussion board, a member asks: “Anybody have a good story to share about collaborating with a casting supplier to achieve a new part design or develop a unique process?” Below are excerpts from some of the discussion points:

“I had an instance where an

OEM wanted to increase the effi ciency of its engine by slightly modifying the port sizes. A whole team worked on it and, using the same core, added and/or removed by rubbing the cores and thickening the coating to make it bigger. Four trials were taken with various combinations and permutations. Only one trial was very successful and the lead time and equipment pattern corebox lead time were reduced by almost one year. R&D by a dedicated team from the OEM and the foundry made it possible.” —Geethamohan

“This is the default mode of

operations in our business. The sad truth is that being a casting supplier operating from California makes our ability to compete

otherwise impossible. The cost structure and regulations make it prohibitively expensive to simply take a purchase order with perfectly correct drawings and specifications and quote it attractively. For that reason our engineering team must be able to understand the design behind the part and be honest about the best process to produce such a part effectively. Often, it starts with unrealistic

expectations from the customer. Examples are a request to make a small quantity of castings, or to pay for a diecast part without investing in die cast tools or in turnaround time that is not possible with diecasting. It takes more than a ‘no bid’ to

explain to the customer why the RFQ should be different.” —Yehoram

BLOG ROLL Knowledge is Power

More and more, metalcasters are sharing their knowledge with the next generation of metalcasters. A quick look at the American Foundry Society website will provide news stories of chapters utilizing tools such as Foundry in a Box to interest youngsters in the fi eld and provide them with hands-on knowledge.

Buyers, designers and casting end users should be privy to the same treatment and take advantage of time spent with their casters. If you do not meet with your metalcaster, consider it. Not only is it a mark of a good relationship, but asking questions and learning metalcasting terms and technology can provide you with the tools to explain exactly what you need in your cast component.

Those less familiar also can

take advantage of courses offered through the AFS Institute, such as An Introduction to Metalcasting. The more you know about the process, the easier it will be to create and design the casting of your dreams. As the phrase goes, knowledge is power.
