Currently, there are five major r & d groups under the sakura flag: the asia-pacific integrated research institute, the china-east research and development centre, the south china research and development centre, the taiwan research and development centre and the general kitchen development centre. Japan, taiwan and mainland china have jointly developed the cherry core technology; technical cooperation for digital heat in taiwan since 1995 has been initiated with the japanese capital to domesticate the critical zero component technology; digital heat technology was transplanted to china in 1999; technical cooperation agreement for energy-efficient digital heat was signed in 2009 between the cherry blossoms of china and the taiwan cherry flower coalition and the lao capital production; china introduced the strategic shareholder "japan power" group in 2013 to enhance the technological level of the gas heaters at both sites. In 2011, the huadong experiment centre was certified as an accredited laboratory, and the overall wisdom of the centre was selected in the total amount of rmb 20 million, with the introduction of advanced detection equipment and instruments such as the german specialized gas heat analyser, the united states angelon gas chromatography analyser, the japan fulfill gas analyser and three sets of automatic sets, which will allow the detection of gas systems for gas heaters and gas stoves, thermal load accuracy, combustion conditions, electrical performance, etc. In order to enable consumers to buy and use properly, cherry blossoms conduct a series of rigorous tests of parts of the product in the laboratory, including acid alkalis, high temperature tolerance, durability, etc., each detail is strictly closed。
