The difference between casement hinges and mother-child hinges Five differences between mother-child hinges and flat hinges




A hinge is a metal material that connects two parts of an object and enables it to move. It is often used for the installation of doors, windows, and cabinet doors. It is the iron sheet that fixes the door in our home. The hinges of doors on the market generally have Two types: casement hinge and mother-to-child hinge. So in terms of aesthetics and installation convenience, which is better, casement hinge or mother-to-child hinge? What is the difference between the two? Let the editor tell you Talk about the difference between the flat hinge and the mother-child hinge. I hope you can use it as a reference when purchasing.


The five major differences between mother-child hinges and flat hinges


strong aesthetics


Judging from the design of the mother-child hinge, it still has a certain difference from the casement hinge. It does not use a slotted design, which can relatively reduce damage to the door and greatly improve the overall aesthetics. It is now a home Ideal hardware use in life, widely used.




the
good applicability


There is still an obvious difference between the mother-child hinge and the casement hinge, which has been greatly improved in design, so that the use of the hinge itself is better. The mother-child hinge takes into account the load-bearing capacity of the door, so that The slotted design increases the integrity of the door and makes its own scope of application wider, which is in line with the applicability of different doors and has a wide range of applications.


the
Good simplicity


The design of the mother-child hinge takes into account the actual decoration needs, and compared with the casement hinge, it also has a good guarantee in terms of simplicity. The mother-child hinge itself is designed taking into account the needs of convenient installation. In actual processing It is relatively easy and has become a widely used hardware product.


the
strong design


The overall design of the mother-child hinge is stronger than that of the casement hinge, and it also pays more attention to practicality and firmness in the overall appearance design. As a commonly used hardware now, the mother-child hinge is the most important part of the connection and installation of doors and windows. The practical effect is obvious, and the installation position can be determined according to the size of the door gap without damaging the overall appearance.


the
poor durability


However, compared with the casement hinge, the mother-child hinge has many advantages, but it also has its own disadvantages, that is, poor durability. The length of the mother-child hinge itself is the same as that of ordinary hinges, but its inside and outside The design connection is not as good as the casement hinge, so the durability is poor. The casement hinge uses four middle rings, while the mother and child hinge has only two, so the performance is slightly inferior.


After reading the introduction of the editor, I believe that everyone has a general understanding of the advantages and disadvantages of the casement hinge and the parent-child hinge. It looks beautiful; although the swing hinge is troublesome to install, it is durable, and it has relatively high technical requirements. You can choose the appropriate hinge according to the situation of your own door. Finally, the editor reminds everyone to choose the swing hinge The page must match the height and width of the slot.


What are the special functions of mother-child hinges and ordinary flat hinges?

When the hinges of the mother and child are closed, they are single-sided thickness, and the closed double-layer thickness of the flat opening. The difference is that when installed on the door, the hinges of the mother and child do not need to be slotted, and they can be directly nailed to the door. For the side-opening door, a groove should be made on the side of the door, and one side of the hinge should be embedded in the groove. This is the difference. The advantage of the mother-in-law is that it is easy to install. The disadvantage is that the bearing capacity is not as good as that of the side-opening door. The advantage of the side-opening is that Good bearing capacity, after all, the force on both sides of the trench is even. Generally, three pieces are installed for the mother and child, and two pieces that are opened flat are enough.

When installing a wooden door, should you choose a mother hinge or a normal hinge? Which brand is better?

In terms of the convenience of use and the adaptability to the door, the mother-in-law hinge undoubtedly has the absolute upper hand. Its biggest selling point is its ease of use, because it does not require slotting compared with the installation of the flat hinge, which directly reduces the number of doors facing. The damage of the door greatly enhances the beauty of the door. More importantly, some non-solid wood doors (composite materials) or hollow wooden doors can't bear the slotting at all, and they are barely slotted to install the side-opening type. After a period of time, There may be serious quality problems such as door leaf falling off and door leaf perforation, but the unique design of the factor mother hinge can be installed directly without slotting, which enhances the integrity of the door and greatly enhances the applicability of the hinge to various types of inner doors.

In terms of durability, the casement hinge is better, because the length of the mother and child hinges is the same as that of the ordinary hinge, but the inner and outer pieces of the mother and mother hinges should be overlapped, so that The inner page shrinks, while the outer page is hollowed out. From this point of view, the durability is definitely not as good as the casement hinge with two complete pages. In addition, the rotation and load-bearing often depend on the middle ring, and the wear resistance of the middle ring The degree of closure and the degree of closure of the central axis directly determine the load bearing. The casement hinge usually has 4 middle rings, and the mother and child have two rings. From this point of view, the durability of the mother and child hinge is worse than that of the casement hinge. reason.

The difference between mother-child hinges and flat hinges Which one is better for mother-child hinges and flat hinges

Mother-child hinge.


1. The beauty and installation convenience are different: the mother-in-law hinge is more convenient to install than the flat hinge. It does not need to slot on the wooden door, but only needs to be installed with screws, and the aesthetics is better.


2. The durability is different: the casement hinge is more durable than the parent-child hinge. When the casement hinge is installed, it needs to slot the door leaf fixed hinge, and the hinge is embedded in the groove. The overall bearing capacity of the hinge It is better than mother-in-law hinges, and it is relatively more durable after a long time of use.


Precautions for the use of mother and child hinges


It should be noted that unlike ordinary hinges, the mother-child hinge is not two plates of the same size, but looks like a pair of mother and child, consisting of a smaller child leaf and a larger mother leaf. The leaf is shaped like a hollowed out part of the mother leaf. Compared with ordinary hinges, the mother and child hinges are thinner and are not suitable for heavier wooden doors.


It should be noted that the core of the hinge is the bearing. The flexibility and durability of the door opening and closing are determined by the bearing. The bearing of the mother and child hinge is lighter than the ordinary hinge. It is better to install three hinges. for better load bearing.

The production of forged aluminum hinges involves several steps, including blank making, pre-forging, final forging, machining, and heat treatment. This article will provide a detailed explanation of each process to help you better understand the production process.
1. Blank Making:
The first step in the production of forged aluminum hinges is blank making. Due to the complex structure and large deformation of long wheelbase hinges, it is not feasible to use bar or profile to make billets as it would greatly increase the forging process. Therefore, a 125OkN die-casting machine is used to die-cast billets at a low speed. This method not only reduces the forging process but also ensures a uniform metal flow and continuous fiber. During die-casting, the die-casting machine's injection rate is controlled by adjusting the valve opening to inject the molten metal slowly. This allows the gas in the cavity to be discharged through the exhaust groove, effectively eliminating defects such as porosity and shrinkage inside the finished blank. X-ray real-time imaging is used to inspect the blank for any internal defects.
2. Pre-forging:
As a result of the low-speed die-casting process, the shape of the blank closely resembles that of the final forging. Thus, only two forgings are required to meet the size requirements. Pre-forging and final forging are carried out to achieve the desired shape. Pre-forging improves the dimensional accuracy of the workpiece and ensures complete filling at the corners of the outer surface. A mold is used on a punching machine to remove the excess material from the pre-forged forging. The pre-forging process includes heating, preservation, forging, and air cooling. This process helps achieve a dense internal structure, excellent surface quality, and stable dimensions.
3. Final Forging:
The pre-forged forging undergoes final forging to further enhance its dimensional accuracy and surface quality. The final forging process completely fills the cavity and ensures a dense internal structure. This is achieved by heating the pre-forged forging, preserving the temperature, forging it with a press, and finally air cooling it. The result is a forging that meets the required size specifications and exhibits excellent mechanical properties.
4. Machining:
After the forging process, the forged aluminum hinge is subjected to machining operations. A special jig is used to process the mounting holes, ensuring precise dimensions and alignment with other components.
5. Heat Treatment:
The final step in the production of forged aluminum hinges is heat treatment. The drawing specifications dictate the use of 6061-T6 aluminum alloy. T6 treatment involves a solution treatment and artificial aging process. For wrought aluminum 6061, the solution treatment is carried out at a temperature of (5405) for a duration of 1/6-1 hour. After the solution treatment, the forging is cooled in cold water. The artificial aging treatment is then performed at a temperature of (1755) for 6-10 hours. This heat treatment process enhances the mechanical properties of the forging, increasing its tensile strength to over 280MPa, thereby meeting the requirements for its intended use.
In conclusion, the production of forged aluminum hinges involves several crucial steps, including blank making, pre-forging, final forging, machining, and heat treatment. Each process is carefully carried out to ensure dimensional accuracy, surface quality, and mechanical properties of the final product. By following these production procedures, manufacturers can produce high-quality forged aluminum hinges that meet the required specifications and satisfy customer demands.
