What is the difference between a hinged hinge and a Sub-mother hinge?

1、The difference between flat hinges and Sub-mother hinges

When the hinge of the Sub-mother is closed, it has a single-sided thickness, while the closed double-layer thickness of the flat opening is different. The difference is that when installed on the door, the hinge of the Sub-mother does not need to be slotted and can be directly nailed to the door edge, while the flat opening needs to be slotted on the side of the door, and one edge of the hinge is embedded in the groove. This is the difference. The advantage of the Sub-mother is easy installation, but the disadvantage is that the load-bearing capacity is not as good as that of the flat opening. The advantage of the flat opening is that it has good load-bearing capacity, After all, the force on both sides of the control slot is uniform. Generally, three branches are installed for the mother and son, and two horizontally opened branches are sufficient.

2、Which one is better to choose between the Sub-mother hinge and the open hinge

At present, the hinges on the market are mainly divided into two types: flat hinges and Sub-mother hinges. From the perspective of aesthetics and installation convenience, Sub-mother hinges are relatively more convenient to install compared to flat hinges. There is no need to groove on wooden doors, only screws are needed for installation, which is more aesthetically pleasing.

But in terms of durability, flat hinges are more durable than Sub-mother hinges. When installing a hinged door, it is necessary to slot the fixed hinge of the door leaf and embed the hinge into the slot. The overall load-bearing capacity of the hinge is better than that of the Sub-mother hinges, and it is relatively more durable after use.

It should be noted that the material of the door and the technical level of the installation workers are relatively high for the flat hinge. If the door chosen by the owner is hollow, the flat hinge cannot be used because the door cannot be slotted. At the same time, workers are required to pay more attention when slotting to avoid damaging wooden doors. In terms of purchase price, the flat hinge is slightly more expensive than the Sub-mother hinges, but the price difference between the two is not significant.
