Constant machinery in the overall leadership of the Soviet Union, after years of development, innovation and excellence supply doors and windows equipment, according to the customer in the use of windows and doors equipment during feedback, and constantly improve the production process, whether it is the use of materials, quality, appearance, or practicality , ease of use, and maintenance of life are further doors equipment maintenance, the true realization of the factory 100 percent qualified, objective hundred percent customer satisfaction. Ying Yang Constant mechanical doors and windows installed in fact not an easy living, there are many problems to install, and now the windows and doors processing equipment - manufacturers of aluminum windows and doors frame debugging as we analyze this: First, the overall stiffness of the door frame difference (a) or start sliding phenomenon closing doors or experiencing windy weather, door frames shaking. (B) the reasons 1, profile inappropriate choice section, strength is not enough. Aluminum doors and windows to prevent the material does not meet the requirements. Substandard material quality steel doors. 2, lined with steel doors and steel configuration does not meet the standard, (generally use steel liner 1.20, but because of the installation up a lot of business owners do not see it with the owners failed to install.) Steel wall is thin, the intensity difference; within lined steel doors and windows equipment segment is inserted, do not form the overall strengthening of the role; lined with steel and plastic profiles connection is not strong and so on. 3, install a node fails to specification. 4, without depending on the wall using different fixation methods. (C) Measure 1, the door window frame profiles specifications, quantities meet national standards. Aluminum profile frame thickness not less than 2.4 mm. Plastic window material thickness not less than 2.5 mm. 2, check the appearance of plastic profiles, qualified profiles should be bluish or ivory white, clean and smooth. Better quality should be protective film. 3, according to the size of window and door openings, mounting height select profiles sectional doors processing equipment, not less than 55 series casement windows, sliding windows not less than 75 series. 4, in strict accordance with specification installation, ensure a solid and stable. Supply of doors and windows equipment, Constant Machinery (certified), doors and windows equipment from Xingyang Constant farming machinery plant. Constant farming machinery factory Xingyang (www.hlyzjx.com) is Zhengzhou, machining leaders, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
