Workers at sanming sanheng printing machinery co., LTD. 's workshop in jinsha park, south China's guangdong province, on Aug. 13, 2008, are making pad plates for sale in shantou, south China's guangdong province. Over the past three years, the company through technical upgrading, the production of the main products pad plate doubled, sales ranked first in the same industry in the province.

　　Sanheng printing machinery company is an old manufacturing enterprise with more than 30 years of pad plate production history. The enterprise mainly USES bearing steel, spring steel, chrome steel, oil steel and other materials, the production of clock printing, electronic printing, printing disk and other special printing industry required plate pad.

　　In recent years, with the continuous improvement of the market, to manual polishing pad plate has been unable to meet the market demand. The company's overseas service department often receives customer complaints and feedback: the product polishing surface is not uniform, the printing qualification rate is not high. At the same time, energy consumption, efficiency is not high, difficult to hire old manufacturing enterprises and other common problems followed.

　　How to get out of trouble? "Machine replacement", to improve the level of automation is imminent, sanheng printing machinery decided to implement technical transformation.

　　Plan before you act. In 2012, the company invested more than 500,000 yuan to update the automatic equipment of the plane grinding process, doubling the work efficiency and successfully taking the first step of the transformation from semi-automation to automation. The following year, according to many years of accumulated experience in technology, the main link grinding, polishing pad printing plate production process upgrading technological upgrading, and independent research and development of mechanical polishing equipment, to replace the manual polishing, and picked up the three national patents: a rotating disc pad printing plate precision grinding machine, rotating disc pad printing steel polishing machine and rotating disc pad printing plate grinding machine. In addition to the core equipment, the company continues to automatic baling machine, sealing machine, cleaning machine and a series of equipment for technical upgrading. After a series of technical upgrading, the company's product pad plate production doubled, customer complaint rate is zero.

　　In addition, in the heat treatment process of pad printing plate production, the temperature of circulating water cooling oil is as high as 90 degrees Celsius, the hot gas can not be evacuated, has been plagued by sanheng printing machinery "old trouble" problem. In May 2013, the company cooperated with refrigeration enterprises in jiangsu province to develop a circulating cooling machine, which can realize hot air evacuation by convection. Li geyang, deputy general manager of the company, said, "the original use of two stoves, recycling water cooling oil temperature up to 90 degrees Celsius. After the technical modification, the temperature of the three furnaces is controlled at 50 degrees Celsius."

　　Technical upgrading to seize the market opportunities. From January to June this year, sanheng printing machinery co., LTD. Produces printing plate more than 3 million inches, the products sell well in China, southeast Asia, Europe and more than 10 countries and regions.

　　"In the next stage, the company plans to cooperate with the haixi (fujian) branch of the general institute of mechanical science and invest 2 million yuan to build the first automatic production line of pad printing steel template in China, so as to realize full automation of the production line and strive for doubling the output." For the future technical transformation, li geyang is quite confident.
