One. What are the different types of hidden door hinges available?
1、Standard hinges
In doors and windows, and for furniture applications, standard hinges are the most common and widely used. However, these hinges lack the functionality of spring hinges, which limits their application in many areas.
2、Cigarette lighter hinge
A "tobacco hinge" is also a type of hinge, specifically a spring hinge. It features a spring located in the middle of the hinge, allowing for better control of doors and windows, as well as furniture. Tobacco hinges are available in galvanized iron and zinc alloy materials, allowing for adjustments in height, width, and curvature. They can also be adjusted to determine the opening angle based on the size of the interior space.
3、Door hinges
This is a highly specialized hinge designed for connecting and rotating large door leaves and door frames. Large door hinges are available in various materials, including copper and stainless steel. Compared to other types of hinges, this hinge offers superior load-bearing capacity and durability.
II. important considerations when selecting hidden door hinges
1、Check the hinge color
Generally, hinges are coated with a layer of lubricating oil, so their color can be used to assess their quality. If you choose imported hinge springs, their surface will typically display a light yellow or off-white lubricating oil, which has a long service life. However, most domestically produced hinges use black yellow or pure white lubricating oils, and the lubricating oil on the surface is prone to drying and has a low viscosity at high temperatures, making it feel sticky when touched.
2、Inspect the hinges for workmanship.
In terms of weight, high-quality hinges are noticeably heavier, while lower-quality hinges feel lighter. In terms of craftsmanship, high-quality hinges have a smooth, finely electroplated surface, and the edges of the spring strips are precisely finished. They also include a nylon protection device. Conversely, lower-quality hinges have rough edges, bubbles, and unpolished spring strip edges, resulting in a poor tactile feel.
3、Inspect the hinge construction.
High-quality hinges are manufactured using cold-rolled steel and a one-piece forming process to ensure excellent durability and a long service life. Quality hinges are heavier, have a smooth surface, and a thick coating, making them resistant to rust and providing strong load-bearing capacity. Conversely, low-quality hinges are typically made of thin steel sheets and lack elasticity, leading to issues such as difficulty closing, loosening, and cracking, especially over time.
4、Inspect screws
Whether it's hinges or pivots, their installation requires screws. High-quality products have screws that are installed correctly and securely, allowing them to be tightened with a screwdriver the first time. In contrast, many low-quality hinges have screws that are not properly tightened, and can even be turned by hand.
