Sumika Completes the Installation of New Grinding Equipment
September 6, 2013
Sumika Electronic Materials, Inc. (SEMI) recently installed particle size reduction equipment to effectively provide ground PES5003P to the US market at their manufacturing facility in Phoenix, Arizona. SEMI provides grinding services of PES5003P primarily for domestic customers who require a smaller particle size by using dedicated Rotary Classifier Mills. Rotary Classifier Mills are integrated mills and classifiers and are designed to provide two distinct grinding sections, one for raw feed and the other for semi-ground material returned by the classifier requiring a higher grinding intensity. This feature provides improved grinding efficiency overcoming the limitations of conventional units in which both feed and oversize returns are ground in a single operation.
In addition, SEMI purchased and installed a Laser Diffraction instrument for precisely measuring particle size of feed stock and of finished product, and an Inductively Coupled Plasma (ICP) instrument that checks for metals before and after the grinding process to insure that the product is free from metallic contamination. Also, SEMI is capable of testing Ash Content by muffle furnace and Moisture Content using a Karl Fischer titration instrument.
SEMI is a wholly owned subsidiary of Sumitomo Chemical Co. Ltd., and Sumitomo is the manufacturer of PES materials. SEMI also manufactures custom epitaxial wafers using a Metal Organic Chemical Vapor Deposition process in a state-of-the-art facility. SEMI is certified to the ISO9001:2008 and ISO14001:2004 quality and environmental standards.
