We are a window hardware manufacturer, and what we are discussing here is the impact of hardware configuration on the performance of aluminum alloy doors and windows.
The types of hardware that affect the sealing performance of doors and windows can be roughly divided into two categories: multi-lock hardware and single-lock hardware. The locking points and lock seats of the multi-locking hardware are distributed around the doors and windows. When the doors and windows are locked, the locking points and the lock seats are firmly buckled together and cooperate with the hinge or sliding brace to produce a strong sealing pressure , So as to provide sufficient sealing performance for doors and windows, so that the fan and frame are integrated. Therefore, the use of multi-lock point hardware can improve the sealing performance of doors and windows.
The sealing performance of single locking point hardware is relatively much worse. Because single locking point can only provide locking on the opening side of the door and window sash, it can only produce three or four places in conjunction with hinges (hinge) or sliding supports. The locking point and the four corners of the window sash are in an unconstrained state, which leads to the overall sealing effect of the doors and windows. According to the mechanics formula and experiments, it is concluded that the use of three locking points can greatly reduce the deformation of the door and window sash and improve the sealing effect. Under the condition of meeting the requirements of strength and sealing, no amount of lock points is equivalent to waste. We are also a door handle manufacturer, welcome to consult and contact us.
