The damage of plastic door and window hardware accessories is generally as follows: the hardware accessories are not firmly fixed, loose and loose, and the pulleys, sliding hinges and the like are damaged, and the opening and closing is not flexible.
It is known that the causes of hardware damage are:
The hardware accessories are not properly selected and the quality is inferior; there is no metal lining when tightening, and there is not enough installation strength.
Measures to prevent damage to hardware:
(1) The sliding hinges shall not be made of aluminum alloy and shall be made of stainless steel.
(2) For sliding windows with a width of more than 1 m, or doors and windows with double glazing, double pulleys or rolling pulleys should be used.
(3) The hardware accessories should be installed at the end. Door and window locks, handles, etc. should be assembled after the window door is inserted into the frame to ensure correct position and flexible switch.
(4) The type, specification and performance of the selected hardware fittings shall conform to the current national standards and relevant regulations, and shall be matched with the selected plastic doors and windows.
(5) After the hardware is installed, pay attention to maintenance to prevent rust and corrosion. In daily use, it is necessary to lightly open and close the door to prevent hard opening and damage.
(6) To install the hardware with the fastening screws, a metal lining must be built in. The thickness of the lining should be at least twice the distance of the fastener. Do not fasten to plastic profiles or use non-metallic linings.
