MDES students visit Modern Metals Foundry Inc. for putter casting project

Engineering Drafting & Design students in the Product Design class recently visited Modern Metals Foundry Inc. in Bloomington, Minn. The visit is part of a golf putter design project the students are working on.

Before the students visited the foundry, Dan Taylor, pattern maker and partial owner of Modern Metals, spent a day in the classroom working with 21 students to create golf putter designs and follow boards that could be easily cast in aluminum.

“At the foundry the students were able to watch the actual process of packing the sand into a core and cavity using one of their putter patterns and follow boards,” said Senior Instructor Andrew LeRoy. “The sand was hardened using a CO2 process. Finally the sprue and runners were cut into the mold and the liquid aluminum was poured into the mold by hand using a ladle. After a cooling period the part was removed and then brought into the grinding area to clean it up.”

When all the putter parts are complete they will be returned to the students to do the final machining of the putters striking faces and installation of the shaft and grip.

“This project makes the design process come to life from conception through final manufacturing of a part using required standards from industry. It is very realistic and mirrors what graduates will face in industry on a smaller scale,” LeRoy said. “Modern Metals has been integral to the MDES program for several years and they really make an invaluable contribution.”

Putter Contest
For this project the students are required to ensure their putter meets United States Golf Association standards of weight and design. In mid to late November the students will host a putting contest for Dunwoody faculty, staff and students–who will be asked to vote for which putter they think is best. The winner will be listed on a trophy displayed in the Robotics & Manufacturing department.
