Complex Mold Production Reduces Lead Time by 9 Weeks & Saves Thousands

Customer Challenge

The customer required extremely fast lead time as well as complicated casting geometry for replacement cyclinders on an old obsolete compressor. MW Smith DXP Engineers, contacted Pumpworks Castings, LLC about the need for 2 Compressor Cylinders on an expedited basis. The challenge; reduce lead time from an estimated 17+ weeks down to 8 weeks without tooling.

The Solution / ExOne Competitive Advantage

Using ExOne technology, Pumpworks Castings, LLC was able to meet the schedule by providing the old obsolete compressor heads to MW Smith DXP in 8 weeks. The complex molds were printed in about 7 days and it was estimated that using a traditional wood pattern to make this complex mold, it would have taken about 8-9 weeks. By using ExOne technology, the mold was made ready for the casting pour in about 1 week versus 8-9 weeks. By printing the complex mold in 1 week, the aggressive delivery of 8 weeks was met and the compressor repairs were started.
