Is Kaiping hinge better or parent-child hinge_Company News

When it comes to durability, flatHingeIt outperforms the mother-child hinge. Although the length of the mother-child hinge is the same as that of the ordinary hinge, the overlapping of its inner and outer pieces reduces the page of the inner piece, making it less sturdy compared to the casement hinge with two complete pages. Furthermore, the rotation and load-bearing capacity of a hinge depend greatly on its middle ring. The wear resistance of the middle ring is directly proportional to the closure of the middle shaft, which determines the load-bearing capacity. In this regard, the casement hinge with four middle rings surpasses the mother-child hinge with only two rings, which explains the lower durability of the latter.

However, in terms of convenience and adaptability to doors, the mother-child hinge undeniably has a significant advantage. Its ease of use is its biggest selling point. Unlike the flat hinge, it does not require slotting during installation, leading to cost reduction and reducing damage to the door. This greatly enhances the door's aesthetics. Additionally, some non-solid wood doors or hollow wooden doors cannot withstand slotting, resulting in quality issues like door leaf detachment or perforation. Nevertheless, the unique design of the mother-child hinge eliminates the need for slotting, improving the door's integrity and increasing the hinge's applicability to various types of interior doors.

In summary, while the flatHingeIt prevails in terms of durability due to its complete pages and multiple middle rings, the mother-child hinge shines in terms of convenience and adaptability to different door types. Both hinges have their unique strengths and weaknesses, and choosing between them depends on individual needs and priorities.
