First, the type, specification and performance of the stamping metal parts shall comply with the current national standards and relevant regulations, and be matched with the selection of plastic steel doors and windows.
Second, for a sliding window with a width of more than 1 meter, or doors and windows for installation of double-glazed glass, double pulleys or rolling pulleys should be used.
Three, sliding hinges shall not use aluminum alloy materials, stainless steel materials should be used.
Fourth, the use of fastening screws to install hardware must be provided within the metal liner, the liner thickness should be at least twice the fastener pitch. Do not fasten on plastic profiles or use non-metallic linings.
Fifth, the hardware accessories stamping should be the final installation, door and window locks, handles, etc. should be assembled after the window into the box, to ensure the correct position, the switch is flexible.
Sixth, hardware accessories stamping parts should pay attention to maintenance after installation to prevent rust corrosion. In everyday use, it should be lightly opened to prevent hard opening and damage.
Hardware accessories stamping manufacturers overview, the current market is more commonly used die-casting hinges. This type of hinge is directly die-cast from zinc alloy, so the quality of zinc alloy is very important. The grade of zinc alloy is not the same, and the quality will be different. Generally speaking, since the hinge is a very important hardware, the selected zinc Alloys are also better than other alloys of zinc alloys. Choosing zinc alloys with impurities will produce brittle hinges, and the bearing capacity will not be strong. After stress-bearing, it will break easily. In addition, the zinc alloy die-casting process will also seriously affect the quality of hinges. In view of the fact that the raw materials of hinges are generally not easy to identify, it is recommended that consumers purchase regular branded products to ensure quality.
