ExOne saves PumpWorks Castings 9 weeks of lead time with industrial 3D printing

PumpWorks Castings, LLC, an industrial pump producer and foundry, is tackling the problem of obsolescence by making use of additive manufacturing know-how. Responding to an pressing request from its buyer MW Smith, a Division of DXP Enterprises, Inc., a rotating tools provider from Longview, Texas, PumpWorks diminished the lead time for the manufacturing of two customized elements down from 17 weeks to simply eight.

For this request, PumpWorks utilized ExOne’s S-Max additive manufacturing system to make 3D sand castings. In line with Jared Helfrich, CCO, ExOne: “This was a really compelling case because the buyer urgently wanted a fast turnaround time for the casting. ExOne’s S-Max system was capable of successfully ship on the mould package deal.”

“We’re thrilled that PumpWorks was capable of meet their clients’ wants through the use of ExOne’s know-how.”

Additive manufacturing vs. conventional manufacturing  

MW Smith’s request was for the manufacturing of two heads for an out of date fuel compressor which is now not in manufacturing. Constructed from Class 40 Forged Iron, the normal manufacturing methodology for these elements can be wooden sample primarily based casting with machining. For the normal course of, ExOne estimates that producers would sometimes run up a tooling invoice of round $70,000. The associated fee is essentially as a result of customized tooling required. In additive manufacturing, no tooling is required to breed the form.

PumpWorks used their ExOne S-Max, to make molds for the heads in silica sand utilizing a furan binder. Roughly one week of 3D printing and full casted half turnaround had been required to finish every mould, versus the anticipated eight/9 weeks for a wooden sample. When assembled, the mould measured 46 x 38 x 46 inches. Liquid forged iron was then poured into the mould and cooled, then the mould was eliminated, leaving the half to be completed and delivered to the client.

By way of this course of, the PumpWorks workforce was capable of meet MW Smith’s eight-week deadline for the elements, and the corporate might start its compressor repairs. “ExOne know-how has empowered our manufacturing workforce to tackle initiatives we’d not have taken on up to now,” stated Mark Welch, Director of Gross sales at PumpWorks Castings, LLC.

“Matching our workforce’s ability units with ExOne’s know-how permits us as a provider of elements to say sure to one-off designs and say sure to quick deliveries.”

3D printing straight from CAD file

Along with the aggressive lead time, and eradication of tooling prices, PumpWorks’ utility of ExOne additive manufacturing meant that the workforce might 3D print direct from CAD file, reasonably than having to manually convert design data into operational knowledge. On this course of, ExOne guarantees 3D printed mould and core accuracies of ± zero.zero11 in. (± zero.three mm). The method achieves geometric complexity and a scale unmatched utilizing standard casting strategies with out the necessity for a bodily sample.
