Quality Data Scandal Spreads to Sumitomo Heavy
Tokyo, Oct. 2 (Jiji Press)--A Sumitomo Heavy Industries Ltd. <6302> unit falsified quality data for metal-processing equipment parts to make them appear to meet customer requirements, the parent company has said.
This followed a string of similar scandals at Japanese manufacturers, including industry peer Kubota Corp. <6326>, whose misconduct emerged last month.
Sumitomo Heavy Industries Himatex Co., the subsidiary, altered inspection results for rolling mill rolls on hardness and other characteristics that were examined, the parent said Monday.
The subsidiary, based in Niihama, Ehime Prefecture, western Japan, also replaced micrographs of metal structures of the rolls with those meeting customer standards. The cylinder-shaped metal product is used in equipment to produce steel plates.
The misconduct affected rolls shipped to 38 of the subsidiary's 66 clients using the product, between October 2017 and last month. It has not been confirmed whether and how much the rolls have impacted the clients' metal-processing equipment.
