The plastic window was first developed by West Germany in the late 1950s and began production in 1959. The original plastic windows were all simple and rough with a single glue structure. With the worldwide energy crisis in 1972, plastic windows with good energy saving effect were widely used in the early 1970s, which also promoted the improvement of profile production technology and improved performance. The original single cavity profile was developed to three cavity and four cavity profile, It has also driven the development of plastic doors and windows in Europe and even Asia. According to incomplete statistics, the use of plastic doors and windows has accounted for 52% of the door and window market in Germany, 48% in Austria, and more than 10% - 20% in Switzerland, Britain, France, Italy and other developed countries; Plastic windows in the United States started in the late 1970s, with an annual growth rate of more than 15%. In Asia, plastic windows are used in Japan, South Korea, Taiwan, Singapore, Thailand, etc. The plastic windows in China started relatively late. The calcium plastic windows and doors produced in the 1970s are substandard and have been basically eliminated. The real production of plastic windows began in 1983 with the introduction of equipment. At that time, the technology was not very advanced, and single cavity or two cavity structural profiles were used. With the improvement of the industry in 1991, a number of manufacturers of extrusion equipment, molds, profiles, assembly equipment and other manufacturers emerged in China; In 1996, with the birth of a new manufacturer that introduced advanced equipment in the 1990s, which was strongly advocated by the state, the development of the industry was greatly promoted. There are more than 2000 profile extrusion production lines, more than 400 profile factories, and more than 3000 assembly plants in China. In 1999, the profile production capacity was 800000 tons, and the annual assembly capacity of doors and windows was 60 million square meters. It has become one of the few industries with rapid development in China. Plastic doors and windows are being accepted by users for their excellent performance.
