Many furniture-making enthusiasts are familiar with hydraulic hinges and often find themselves faced with a wide range of options when it comes to purchasing them. However, they may wonder why there is such a significant difference in price between products that seemingly look the same. In this article, we will delve into the hidden tricks behind these hinges and shed light on why cheaper products are priced the way they are.
First and foremost, one of the primary factors contributing to the price discrepancy is the quality of materials used by manufacturers. In an effort to reduce costs, many hydraulic hinge manufacturers opt for inferior materials. Consequently, the overall quality of these hinges is compromised, as high-quality materials are not utilized for their production. This cost-cutting measure is a significant contributor to the lower prices of these hinges.
Another crucial aspect to consider is the thickness of the hinges. Many manufacturers choose to use a thickness of 0.8mm, which is significantly less durable compared to hinges with a thickness of 1.2mm. Unfortunately, the difference in thickness is not easily noticeable, and manufacturers may fail to mention this important detail. As a result, customers often overlook this vital aspect and unknowingly compromise the longevity of their hinges.
The surface treatment process, also known as electroplating, is another factor that impacts the price of hydraulic hinges. Different electroplating materials are available at varying price points. Nickel-plated surfaces, for instance, offer high hardness and increased resistance to scratches. Connectors, especially those used for plugging and unplugging, benefit from nickel-plating, as it enhances wear and corrosion resistance. Opting for low-priced electroplating may lead to rust formation and significantly reduce the lifespan of the hinge. Consequently, choosing lower-cost electroplating saves manufacturers money and contributes to the lower prices of these hinges.
The quality of hinge accessories, such as springs, hydraulic rods (cylinders), and screws, also plays a pivotal role in determining the overall quality of hydraulic hinges. Among these accessories, the hydraulic rod is of utmost importance. Manufacturers commonly use materials like steel (No. 45 steel, spring steel) and stainless steel. However, solid pure copper is regarded as the most commendable material due to its high strength, hardness, and resistance to chemical corrosion. Additionally, it aligns with international environmental protection standards. Manufacturers who utilize high-quality accessories, specifically solid pure copper hydraulic rods, can ensure the durability and longevity of their hinges.
The production process employed by manufacturers is yet another factor that contributes to the price of hydraulic hinges. Some manufacturers employ fully automatic production processes for the hinge bridge body, hinge base, and link parts. Such manufacturers have stringent inspection standards, resulting in very few defective products entering the market. On the other hand, some manufacturers simply rush the production of hinges, paying little attention to quality requirements. These low-quality products naturally lead to a significant price disparity in the market.
After considering these five points, it becomes clear why some hinges are significantly cheaper than others. The old adage "you get what you pay for" rings true in this case.

As more and more people embrace DIY projects, the trend of self-installing cabinet hinges is gaining popularity. When purchasing hinges for your cabinets, it's important to understand the different types available based on the position of the door panel and the side panel of the cabinet. Hinges are categorized as full cover, half cover, or no cover.
A full cover hinge, also known as a straight arm hinge, is used when the door panel fully covers the vertical side of the cabinet where the hinge is installed. On the other hand, a half cover hinge is suitable when the door panel covers only half of the cabinet's side. Lastly, a big bend hinge is used when the door panel does not cover the side of the cabinet at all.
The selection of full cover, half cover, or inlay hinges depends on the specific side panel of the cabinet. Generally, the side panel thickness ranges from 16-18mm. The cover side panel is 6-9mm thick, while the inlay hinge allows the door panel and side panel to be on the same plane.
In practice, if the cabinet is built by a decorator, it usually comes with half cover hinges. However, if the cabinet is custom-made at a factory, full cover hinges are more commonly used.
To summarize, hinges are essential and widely used hardware for cabinets and furniture. Their prices vary from a few cents to tens of yuan, making them a crucial component for upgrading furniture and cabinets. Hinges can be divided into regular hinges and damping hinges, with the latter further categorized as built-in or external. Different hinges have distinct material choices, workmanship, and prices.
When choosing hinges, it's important to inspect the material and feel its quality. If budget allows, opting for hydraulic damping hinges, such as those from Hettich and Aosite, is recommended. It would be best to avoid external damping hinges as they tend to lose their damping effect over time.
When purchasing non-damping hinges, there is no need to solely focus on European brands; domestic brands can be a suitable choice. Depending on the position of the door panels and side panels, there are three types of hinges: full cover, half cover, and big bend. In practical use, decorators generally opt for half cover hinges, while cabinet manufacturers prefer full cover hinges.

Which Hinge Should You Use for an Upward-Opening Door?
When discussing upward-opening doors, it is important to specify whether you are referring to furniture doors, cabinet doors, or standard household doors. In the context of doors and windows, upward opening is not the common method of operation. However, there are top-hung windows in aluminum alloy doors and windows that open upwards. These types of windows are often found in office buildings.
Top-hung windows do not use hinges but instead utilize sliding braces (available for download on Baidu) and wind braces to achieve the upward-opening and positioning effect.

Now, let's discuss how to choose the appropriate hinges for your doors and windows.
1. Material: Hinges are generally made from stainless steel, pure copper, or iron. For home installations, it is recommended to choose 304 stainless steel due to its practicality and cost-effectiveness compared to pure copper, which is more expensive, and iron, which is prone to rust.
2. Color: Electroplating technology is commonly used to provide a variety of color options for stainless steel hinges. Choose a color that matches the style of your doors and windows.
3. Types of Hinges: There are two main types of door hinges available on the market: side hinges and mother-to-child hinges. Side hinges, or standard hinges, are more practical and hassle-free as they require manual slotting during installation. Mother-to-child hinges are more suitable for lighter PVC or hollow doors.
Next, let's discuss the number of hinges needed for proper installation:
1. Interior Door Width and Height: In general, for a door with dimensions of 200x80cm, it is recommended to install two hinges. These hinges are usually four inches in size.
2. Hinge Length and Thickness: High-quality hinges with a length of approximately 100mm and an unfolded width of 75mm are commonly available. For thickness, either 3mm or 3.5mm should suffice.
3. Consider the Door Material: Hollow doors typically only require two hinges, whereas solid wood composite or solid log doors may benefit from three hinges.
Furthermore, there are invisible door hinges, also known as concealed hinges, which offer a 90-degree opening angle without affecting the door's appearance. These are ideal if you value aesthetics. Meanwhile, swing door hinges, also called Ming hinges, are exposed on the outside and offer a 180-degree opening angle. These are essentially common hinges.
Now, let's move on to discussing the types of hinges used for anti-theft doors and their installation precautions:
With an increasing focus on safety, more households are using anti-theft doors that offer enhanced security. The hinges used in these doors play a crucial role, so we will cover the main hinge types and installation precautions.
1. Types of Anti-Theft Door Hinges:
a. Ordinary hinges: These are commonly used for doors and windows. They are available in various materials, including iron, copper, and stainless steel. Note that they do not have the function of a spring hinge and may require additional touch beads for door panel stability.
b. Pipe hinges: Also known as spring hinges, these are used to connect furniture door panels. They typically require a plate thickness of 16-20mm and are available in galvanized iron or zinc alloy materials. Spring hinges come equipped with an adjusting screw, allowing for height and thickness adjustment of the panels. The angle of door opening can vary from 90 degrees to 127 degrees or 144 degrees.
c. Door hinges: These are categorized into ordinary type and bearing type. Bearing hinges are available in copper and stainless steel, with stainless steel being the more commonly used material.
d. Other hinges: This category includes glass hinges, countertop hinges, and flap hinges. Glass hinges are designed for frameless glass doors with a thickness of 5-6mm.
2. Installation Precautions for Anti-Theft Door Hinges:
a. Ensure that the hinges match the door and window frames and leaves before installation.
b. Check if the hinge groove aligns with the height, width, and thickness of the hinge.
c. Verify that the hinge is compatible with other connecting screws and fasteners.
d. Install hinges in such a way that the hinge shafts of the same door leaf are aligned vertically.
These are the types of hinges commonly used for anti-theft doors, along with some installation precautions. For more detailed information, please visit our official website. Pay attention to these small details during the installation process for optimal results.
