Types of Hinges for Different Door Applications
Hinges play a vital role in door installation and functionality. They are responsible for connecting two solids and allowing relative rotation between them. While ordinary hinges are commonly used for cabinet doors, windows, and regular doors, there are many other types of hinges available for specific applications. Let's explore some of these hinges in detail:
1. Butt hinge: This is the most common type of hinge and is often used for regular doors. It consists of two rectangular plates, one attached to the door frame and the other to the door itself. The plates are connected by a pin, allowing the door to swing open and closed.
2. Continuous/piano hinge: This type of hinge runs the full length of the door, providing continuous support and smooth operation. It is commonly used on heavy doors, such as those found in commercial buildings or industrial facilities.
3. Concealed hinge: As the name suggests, concealed hinges are hidden from view when the door is closed. These hinges are often used for cabinet doors, as they provide a clean and seamless appearance.
4. Pivot hinge: Pivot hinges allow the door to rotate on a single point, typically located at the top and bottom of the door frame. These hinges are commonly used for large, heavy doors or doors that need to swing in both directions.
5. Strap hinge: Strap hinges are decorative hinges that add a rustic or antique touch to doors. They consist of two long plates, usually made of iron or steel, connected by a pin. Strap hinges are often used for barn doors or large gates.
6. European hinge: Also known as concealed hinges or cup hinges, European hinges are widely used in modern cabinet and furniture construction. They are hidden from view when the door is closed and provide adjustable and soft-closing features.
7. Ball bearing hinge: Ball bearing hinges use ball bearings to reduce friction and allow smooth door operation. They are commonly used for heavy-duty doors, such as those found in high-traffic areas or commercial buildings.
8. Spring hinge: Spring hinges are self-closing hinges that automatically return the door to its closed position after being opened. They are often used in residential or commercial settings where doors need to be kept closed for security or energy efficiency purposes.
9. Double acting hinge: Double acting hinges allow the door to swing open and closed in both directions. They are commonly used for doors in restaurants, hospitals, or other environments where foot traffic flows in both directions.
10. Gate hinge: Gate hinges are specifically designed for outdoor gates or fences. They are typically made of heavy-duty materials, such as stainless steel or galvanized iron, to withstand harsh weather conditions and provide durability.
These are just a few examples of the various types of hinges available for different door applications. Each hinge has its own unique features and benefits, allowing doors to function properly and meet specific requirements. When choosing a hinge for your door, consider factors such as door size, weight, style, and desired functionality to ensure the best fit.

When it comes to choosing cabinet door hinges, there are several factors to consider. It's important to invest in good-quality hinges that are durable and functional. Here are some tips on how to choose the right cabinet door hinges:
1. Material: Cabinet door hinges are typically made of stainless steel or semi-stainless steel. Stainless steel hinges are more resistant to rust and corrosion, making them a better choice for long-lasting durability.
2. Type of hinge: There are two main types of cabinet door hinges: positioning hinges and hydraulic hinges. Positioning hinges allow the door to be opened at a specific angle and stay in place. Hydraulic hinges have built-in dampers that control the closing speed and prevent slamming.
3. Types of hinge bends: Hinges come in different bends, including large bend, medium bend, and straight hinge. The bend refers to the angle at which the hinge arm is bent. The choice of bend depends on the type of door panel and the desired coverage of the cabinet side panel.
- Full cover hinges: These hinges cover the entire side panel of the cabinet and are typically used for doors that fully cover the side panel. They provide a smooth opening and closing action.
- Semi-shrouded hinges: These hinges are used when two doors share a side panel. There is a minimum required gap between the doors, and the distance covered by each door is reduced. This requires the use of hinges with bent arms.
4. Adjustability: Good-quality hinges should offer adjustment options for door coverage distance, depth, height, and spring force. These adjustments allow you to fine-tune the positioning and operation of the cabinet doors.
5. Installation method: The installation method of the hinges depends on the type of cabinet and the desired door coverage. There are three common installation methods: full cover door, half cover door, and embedded door. Choose the installation method that suits your cabinet design and requirements.
To install cabinet door hinges, follow these steps:
1. Determine the minimum door margin based on the thickness of the door panel and the hinge cup margin.
2. Choose the number of hinges based on the width, height, and weight of the door panel.
3. Select hinges that are compatible with the shape and opening angle of the cabinet.
4. Install the hinge cups and hinge seats according to the chosen installation method.
5. Adjust the door panel by loosening the fixing screws on the hinges and sliding the hinge arm to the desired position. Tighten the screws once the adjustment is complete.
Remember to consider the weight of the material, the feel of the hinge, and the details of the product when choosing cabinet door hinges. Classifications of hinges include pipe hinges for furniture door panels, door hinges for heavier doors and windows, and ordinary hinges for lightweight doors and windows.
By following these guidelines, you can choose the right cabinet door hinges that are durable, functional, and suitable for your specific cabinet design.

Ordinary sound-proof electromagnetic screen doors have a large self-weight and closing resistance, and the hinges are easily deformed and damaged, resulting in unsatisfactory sound insulation and shielding performance. In order to solve this problem, the screen door, hinges, and hinge shafts have been taken as the research objects, and three-dimensional modeling and finite element analysis have been carried out to obtain the distribution law of stress, displacement, and safety factor of the components. Through the analysis of the data and graphic parameters, the structure has been designed and optimized, and the strength of the hinge and hinge shaft has been strengthened. The strength of the hinge shaft is particularly important for door leaf applications.
The design of the soundproof screen door focuses on weight reduction. The frame of the door is usually made of rectangular steel pipe, made of ordinary carbon steel, and the interior of the door is filled with wooden boards. In order to increase the sound insulation effect and reduce the weight of the door, it is filled with thermal insulation cotton with a density of 30kg/m3, with a filling volume of 0.3m3. The frame of the door leaf and door frame is made of aluminum alloy 6061-T6, and the total weight of the door is about 130kg.
After the trial production of the soundproof screen door, some problems were found during the inspection. The hinge was difficult to turn and produced abnormal noise, and the door closing resistance was large and lasted for a long time. To analyze these issues, the motion of the S81 and S201 hinges was analyzed separately.
Under ideal conditions, motion analysis was conducted on the S81 hinge using SolidWorks software. It was found that when the angle between the door leaf and the door frame was about 25°, resistance started to appear during the door closing action. As the door continued to close, a greater force was required to completely close the door. After replacing the S201 hinge, the problem was greatly improved. Analysis showed that the S201 hinge required less force and a shorter duration during the door closing process, making it more suitable for workplaces with large door closing force and requirements for sealing and sound insulation.
The strength analysis of the S81 hinge structure revealed that the hinge shaft had exceeded its use requirements, and the upper hinge shaft had a safety factor less than 1. Therefore, the structural strength of the S81 hinge needed to be checked and analyzed. Finite element analysis was conducted on the S81 hinge using SolidWorks software. The analysis showed that the maximum stress point occurred on the hinge shaft, close to the constraint end, with a value of 231MPa. The upper hinge shaft did not meet the strength requirements, and the lower hinge shaft was on the edge of failure.
To improve the strength of the hinge shaft, the structural size and material of the upper and lower hinge shafts were redesigned. The diameter of the hinge shaft was increased from 9.5mm to 15mm, and the shaft hole of the hinge was expanded accordingly. The strength of the hinge was verified through analysis, and it was found that the redesigned hinge shafts met the strength requirements.
In conclusion, through the analysis and optimization of the screen door structure, as well as the strengthening of the hinge and hinge shaft, the strength and reliability of the soundproof screen door have been improved. The redesigned hinge shafts effectively support the weight of the door and ensure long-term performance.

Expanding on the existing article, I will provide a more detailed analysis and explanation of the problem with ordinary sound-proof electromagnetic screen doors and the solutions that have been proposed.
Ordinary sound-proof electromagnetic screen doors are known to have a large self-weight and closing resistance. In addition, the hinges on these doors are easily deformed and damaged, which leads to unsatisfactory sound insulation and shielding performance. To address these issues, a comprehensive study was conducted on the screen door, hinges, and hinge shafts. Three-dimensional modeling and finite element analysis were employed to understand the distribution of stress, displacement, and safety factors of these components.
Through the analysis of the collected data and graphical parameters, the structure was redesigned and optimized to strengthen the strength of the hinges and hinge shafts. The strength of the hinge shaft was identified as particularly important for the overall performance of the door leaf applications.
Designing a soundproof screen door with weight reduction in mind was among the primary objectives. The frame of the door is typically made of rectangular steel pipe, using ordinary carbon steel, and filled with wooden boards for added insulation. To enhance the sound insulation effectiveness and reduce the weight of the door, thermal insulation cotton with a density of 30kg/m3 was used as filling, with a volume of 0.3m3.
After the initial production of the soundproof screen door, several issues were identified during inspection. Firstly, the hinges were difficult to turn and produced abnormal noises. Secondly, the door closing resistance was high and lasted for an extended period. To address these problems, a comprehensive analysis of the S81 and S201 hinges was conducted separately.
Under ideal conditions, motion analysis was performed on the S81 hinge. It was observed that when the door leaf and door frame formed an angle of approximately 25°, resistance started to appear during the closing action. As the door continued to close, a higher force was required to fully close it. When the S201 hinge was used instead of the S81 hinge, the problem was significantly improved. The S201 hinge was found to require less force and had a shorter duration of force application during the door closing process.
Based on these observations, it was concluded that the structure of the S201 hinge was more reasonable and better suited for workplaces requiring large door closing forces and superior sealing and sound insulation.
Subsequently, a detailed strength analysis was conducted on the S81 hinge structure. The 3D solid model of the hinge was created using SolidWorks software, and material properties were defined. Finite element analysis was performed on the hinge to understand its strength under various loads and working conditions.
The analysis showed that the maximum stress point occurred on the hinge shaft, close to the constraint end, reaching a value of 231MPa. This exceeded the allowable stress limit, indicating the need for material and structural redesign. The upper hinge shaft also had the minimum safety factor, indicating a need for improvement.
The upper and lower hinges were found to meet the strength requirements, while the hinge shafts required optimization. The upper hinge shaft was redesigned by increasing the diameter from 9.5mm to 15mm, resulting in a maximum stress point of 101MPa and a safety factor greater than 2. The lower hinge shaft was also thickened to 15mm and met the strength and safety requirements.
Verification of the hinge strength showed that both the upper and lower hinges met the actual needs, with maximum stress points of 29MPa and 22MPa, respectively.
In conclusion, this study successfully identified the issues with ordinary sound-proof electromagnetic screen doors and proposed solutions. Through comprehensive analysis, the strength and reliability of the hinges and hinge shafts were improved, meeting the required standards. These enhancements contribute to the overall performance and effectiveness of sound insulation and shielding in screen doors.
