PostProcess Technologies, which expanded its path spouse coverage in North America the following spring, is well known for its software and post-printing mixtures. With its automated Hybrid DECI Duo solution, PostProcess helps its purchasers achieve good skin-deep finish standards and replicable reactions for complex metal parts.
Recently, PostProcess demonstrated in a brand-new case study how well its engineering can help other fellowships. The topic was Ingersoll Rand, a $14 billion world industrial manufacturing firm that specializes in contracted breeze technologies. The firm applies 3D publication for its shrouded impellers, which improve the performance of a compressor pack more than open impellers because there is no permission between the stationary flue and the impeller, so no plunge loss come as a result of tighten gas recirculating in the space.
The design for shrouded impellers, which revolve 60,000 RPM, has very tight forbearances in order to meet aerodynamic testing. In additive, the blades requirement good face stop, and it takes months to build exploiting conventional forms of manufacturing. So Ingersoll’s engineering team, required to be commercialize its shrouded impeller designing, turning now to 3D printing because of its complete scheme opennes; the technology too impels it possible to build the component as monolithic, so no welding is involved. But, in order for 3D printed fractions to satisfy conduct doorsteps, they do expect exemplary skin-deep finishes.
Ingersoll 3D books its shrouded impellers out of titanium and nickel alloy, but they unfortunately come off the print berth at an Ra( roughness average) importance that doesn’t meet the engineering team’s specifications. The crew has tried everything from manual sanding and grind tools to chemical etching, but the results were inconsistent and did not have the necessary, repeatable quality needed to produce end places within the required specifications.
The company needed to find a replicable process that they are able to supplied with the necessary skin-deep finish for its shrouded impeller’s complex geometry, in order to be allowed to, as PostProcess wrote in its case study,” drive a discernible increase in productivity for its advanced aura compressors .”
So, Ingersoll turned to PostProcess in hopes that the company could work with complex metal division geometries, like organic shapes and internal directs, and help achieve repeatable results and superb surface finish standards for its shrouded impellers.
PostProcess delivered a” transformative outcome” for Ingersoll’s 3D reproduced titanium and nickel alloy portions, thanks to its patent-pending, automated Hybrid DECI Duo solution. The Hybrid DECI Duo- a single, multi-functioning, data-driven method- hopes fast cycles/second periods for even the most complicated of parts Designed to optimize production storey infinite, information systems also includes sounds shortening pieces for a low dBa, an LED illuminated cavity, and a manual procedure for hands-on component finishing when needed.
The system also abuses PostProcess’ proprietary AUTOMAT3D application, in order to be allowed to optimize intensity and exclusive chemistry, which includes detergents and suspended solids so the geometries maintain their fine-feature details while still receiving the desired face finish.
” We have chosen the DECI Duo because of its repeatability, minimum setup, processing epoches, and cost of possession. Photochemical machining, extrude honing, and micro polishing or micro machining all fruit very good results when applied correctly, however extensive tooling and equipment payments, setup terms, and required DOE’s prior to applying the surface finishing technique to obtain a repeatable process have represented the DECI Duo a better option ,” said Ioannis Hatziprokopiou, Mechanical Engineer, New Product Development, Ingersoll Rand Compression Technologies and Services.
” In additive, some of aforementioned finishing proficiencies unevenly remove substance inside the flow track of the impeller, whereas the DECI Duo uniformly treats the part skin-deep of the flow move. The final geometry of the flow course must remain as unaltered as possible after post-processing of any kind .”
The PostProcess solution fixed controlling trains that were in line with Ingersoll’s standards employing mark parts. Then, the DECI Duo was able to consistently finish metal percentages that were able to successfully progress exacting aerodynamic tests.
Ingersoll came to PostProcess with a need for high quality and requirements under consistency and repeatability. But, it’s also achieved additional advantages from is collaborating with the company, such as cost savings and easy of operation.
In addition, the DECI Duo likewise developed an average of 70 -8 0% reduced by Ra for proportions run for 20 times or less.
