8. Door Sheet And Door Frame Friction
Hinges side debris, close the door and cause the hinges by the impact of the external squeeze so that the door surface hinge parts deformation, resulting in indoor surface and door frame friction generated by the sound and paint wear; open the door with excessive force, and cause the hinges by the impact of external squeeze the door surface or door frame displacement, may cause the door surface and door frame friction generated by the sound and paint wear; door seam precision is too high and door surface and door frame gap are uneven or door surface and The door surface and the door frame may be rubbed to produce a rattling sound and wear to the paint surface.
Tighten the expansion screws on both sides of the door frame and widen the distance between the door frames. Use 1~3CM thick long wooden strips to place at the friction, close the door surface and slowly press hard to eliminate the friction. Use an adjustable spanner to adjust the door surface hinge screws, so that the door surface and door frame gap in the best position can be.
