The problem appeared in an otherwise stable production process. Removed residue from the surface of the window jamb and analyzed with FT-IR spectroscopy. Impact developed a method for comparative measurement of the percent of open cell area of the polishing foams.
A sample of the split component was examined using optical and scanning electron microscopy. Comparison with a sample of blasting media used to polish the parts during production identified this media as the contamination. Mechanical Parts Industry Problem: When imaged at high magnification, the fracture surface characteristics indicated poor fusion was occurring in the middle layer during the co-extrusion process.
The fuel line extrusion step was producing a product that appeared normal by usual quality control inspection but had a hidden defect. IA identified and applied a chemical process to stabilize the material and clearly stain the micro-phase domains.
Manufacturer of precision polyurethane foam polishing pads for the semiconductor industry needed a method to measure cell size and open cell area for quality control, Plugging in the consumer case analysis well as for comparison with competitive products.
Chemical staining provides contrast to clearly identify polymer phases in representative digital micrographs, supplied within the report to the customer. A three layer, co-extruded plastic fuel line component was splitting when sent to a supplier for unit assembly.
A third party coating applier denied contamination was occurring during its process. TEM images of cross sections afforded direct comparison of surface and bulk morphologies, enabling informed evaluation of manufacturing processes. Rejects and returned product were increasing.
Gas Chromatography-Mass spectrometry GC-MS confirmed that the oil found on the surface of the part and the resin was the same, and enabled the customer to decide whether to change the resin used or change the conditions of environmental testing. Characterizing the fibers aided in determining the source.
The part manufacturer was able to prove the contaminant was the applied coating and work with the third party supplier to eliminate the problem.
Disassembly and microscopic evaluation of the cartridge components revealed contaminant fibers collecting on the cartridge filter screens.
The ink manufacturer was able to make adjustment to the ink processing and eliminate the problem. Results enabled the team to pursue a modification technique producing consistently superior surface adhesion of the particles to the matrix, as verified by IA microscopy data.
When fittings were inserted, the fuel line split from the applied hoop stress. Ink Jet cartridges plugging prematurely.
Oil was also found in the resin of one of the plastics used in the window jamb. A manufacturer of machined metal parts was finding contamination of a bearing surface. Unknown residue appeared on the surface of an extruded plastic car window jamb after environmental testing at one facility, but not at another.
The analysis suggested the molding conditions be evaluated and corrected. Manufacturer of multi-layer films for the food packaging industry needed to measure the thickness of layers for quality control.
Impact used a combination of polarized light microscopy and infra red microscopy to photograph, measure, and identify the separate layers of the film in cross section. Cartridges for ink jet printing were plugging before the ink was consumed. Impact modified an existing optical microscopy ASTM method, for measurement of the cell size of the micro-porous PU foams in the scanning electron microscope.
Contaminant on surface of steel engine parts caused production slowdown and rejection of product. Impact photographed the fractured surfaces of the samples at high magnification in the scanning electron microscope, to clearly document the difference in surface adhesion as a result of experimental modifications.
Impact used precision cryoultramicrotomy technique to create ultra thin sections of the material for examination in the transmission electron microscope TEM. Impact recommended more thorough cleaning after this interim polishing step. Plastic fuel line splitting during manufacture.
Analysis determined the material to be an oil or oleamidea material often used as a slip agent in the molding process. Impact examined the shape morphology and analyzed the elemental composition of the microscopic metal particles of contaminant in the scanning electron microscope.Case Study - Energy MBA - Students: Tyler Wunsch, Yan Chen, Ana Oliveira "Plugging In" the consumer: The Adoption of Electrically Powered Vehicles in the U.S.

consumer interest in non-fossil fuel vehicles is relatively positive. There are several issues that American faced about fossil fuel such as pollution, dependency on oil imports, concerns of how long fossil fuel supply will be worn-out and especially fluctuation of foreign-oil prices and the more expensive cost of fuel for American household.
