Three major precautions to prevent damage to the gold precision stamping parts
The three major considerations for preventing damage to the gold precision stampings are as follows:
1, in the daily use of light and light, to prevent hard open, resulting in damage. Without noise, there is now a nylon wheel. Not only does it push and pull up without noise, but it is smoother, lighter and has a shorter service life than the various pulleys above. To make the (door) window work. A smooth run requires a high – quality pulley for the window. Hard metal stamping processing poor quality she pulleys from the surface, work is relatively rough, no smooth, sliding up inflexible, small and light.
2, the selection of gold accessories models, specifications and performance should comply with the current national standards and relevant demarcation, and with the selection of plastic steel doors and windows to match. Hardware is installed with fastening screws and must be fitted with a metal liner that should be at least twice as thick as the fastener pitch. Do not fasten to plastic profiles or use non-metallic linings.
3, metal stamping parts after installation to pay attention to maintenance, to prevent rust erosion. Hardware accessories should be finally installed, door and window locks, hand-held, etc. should be in the window door fan into the box after assembly, to ensure accurate location, flexible switch. For sliding windows with a width of more than 1 meter, or doors and windows with double glazing, it is advisable to set up double pulleys or to use dynamic pulleys. Sliding hinges shall not be made of aluminum alloy and shall be made of stainless steel.
