在80年代,中国双螺杆挤出机行业仍是一片空白,国内所需设备皆依赖进口,价格十分昂贵。80年代末,中国第一台商业化国产双螺杆挤出机诞生,刘光知先生正是这台设备的研制者。从80年代末到90年代初,国产双螺杆挤出机开始逐步出现在国内市场,打破了国外设备的垄断地位。“将一项技术转化成一个市场产品,需要走很多路。”在回忆起当初的研发经过时,刘光知先生如此总结。 In the 1980s, China’s twin-screw extruder industry is still a blank, the domestic equipment needed are dependent on imports, the price is very expensive. The late 80s, China’s first commercial domestic twin-screw extruder was born, Mr. Liu Guangzhi is the device developer. From the late 80s to early 90s, domestic twin-screw extruder began to gradually appear in the domestic market, breaking the monopoly of foreign equipment. “It takes a lot of road to get a technology into a market product.” Mr. Liu Guangzhi concluded, recalling the original R & D process.
