Displaying items by tag: TestingNumberland engineering consultancy for new processes, new materials. New processes: We analyse, optimize and document processes often not covered by quality management handbooks and teach them to run. We translate technical demands into physical effects or properties and then find the suitable material.http://www.coating-materials.de/index.php/get-in-contact/itemlist/tag/Testing2016-07-29T20:08:38+02:00Joomla! - Open Source Content ManagementTesting of sintered parts2015-01-18T20:47:39+01:002015-01-18T20:47:39+01:00http://www.coating-materials.de/index.php/get-in-contact/item/1387-testing-of-sintered-partsAdministratorgrond@numberland.de<div class="K2FeedImage"><img src="http://www.coating-materials.de/media/k2/items/cache/a837e119cd945083823082e324cfb9ef_S.jpg" alt="Testing of sintered parts" /></div><div class="K2FeedIntroText"><h1><span style="display: inline; float: none; position: static; font-size: 14px; font-weight: bold; font-family: Tahoma,Arial,sans-serif; font-size-adjust: none; font-style: normal; font-variant: normal; line-height: 14.3px; text-align: left; text-decoration: none; text-indent: 0px; text-shadow: none; text-transform: none; word-spacing: normal;">Testing of sintered parts</span></h1> </div><div class="K2FeedFullText"> <p>ID: F1501-10</p> <p>Non-destructive evaluation (NDT) techniques tο detеct defects in complеx compοnentѕ mаde frοm metal powders are currently lacking.
