Product information
Products Description
SKYSEN industrial-grade vinyl door spring hinges adopt a four-layer composite structure: 80μm electrostatic spray outer layer, 30% glass fiber reinforced vinyl core, 304 stainless steel bearing system, and embedded torsion spring (torque adjustable 5-20N·m). The original 32.5mm three-dimensional adjustment slot automatically compensates for foundation settlement; the electrophoretic M6 anti-theft bolt resists 40kN shear force. Passed 7000 hours salt spray test (ASTM B117), and maintained elastic reset in extremely cold environment of -60℃. Suitable for security places with frequent switching. As an IATF 16949 certified manufacturer, we provide 200,000 switching life guarantee.
Products Description
-
Superior Weather ResistanceMade from high-quality vinyl, our spring hinges withstand extreme weather conditions. In tests simulating 1,000 hours of continuous exposure to sunlight, rain, and high and low temperature cycles, the vinyl material showed no signs of cracking, fading, or deformation. This ensures a service life of at least 15 years, much longer than traditional metal hinges in similar environments.
-
Adjustable Spring TensionThe spring tension of our hinges is adjustable from 3 - 10 Nm. This flexibility allows users to customize the closing force based on the weight and size of the door. For example, heavier vinyl doors can be set with a higher tension for a smooth and reliable close, while lighter doors can use a lower tension to prevent excessive force.
-
High Load-Bearing CapacityDespite being primarily made of vinyl, these hinges can withstand a maximum load of 100 pounds. The combination of vinyl and metal inserts evenly distributes the weight, ensuring that the hinges can withstand the stress of frequent opening and closing. After being tested for 100,000 opening and closing cycles under a 100-pound load, the hinges are still functioning normally without any noticeable wear or damage.
-
Quiet and Smooth OperationThe internal structure of the hinge is optimized for quiet and smooth operation. The spring mechanism is designed to reduce friction and the pivot points are well lubricated. During the opening and closing process, the noise level is kept below 30 decibels, creating a quiet environment. This is particularly suitable for residential areas where noise reduction is required.
-
Excellent Auto-Closing FunctionOur spring hinges are designed for precise auto-closing. The spring returns the door to the closed position smoothly, and the closing speed is adjustable to prevent slamming. In one test, the door closed gently within 3 - 5 seconds, ensuring safety and convenience.
-
Non-Corrosion PerformanceThese hinges are highly corrosion-resistant due to the use of vinyl material and corrosion-resistant metal inserts. In a salt spray test lasting 500 hours, no signs of rust or corrosion were detected on the hinge surface. This makes them ideal for use in coastal areas or areas with high humidity.
Product Testing
Weathering Test
The hinges are placed in a climate-controlled chamber that simulates real-world weather conditions, including sunlight, rain, and temperature fluctuations. They are continuously exposed to these conditions for 1,000 hours. After the test, the vinyl material is inspected for any signs of degradation, such as cracking, fading, or softening. The results show that our vinyl door spring hinges remain intact with no visible damage, proving their excellent weathering resistance.
Spring Tension Adjustment Test
The spring tension of the hinges is adjusted to different levels within a specified range (3 - 10 Nm). These hinges are then used to install a series of doors of different weights. The closing force and smoothness of each door are evaluated. The test shows that the hinges can effectively adjust the closing force according to the weight of the door, ensuring proper operation.
Load-bearing Test
A weight equivalent to 100 pounds is applied to the hinges, and the hinges are subjected to 100,000 opening and closing cycles. During the test, sensors are used to monitor the structural integrity of the hinges, such as whether there are signs of deformation or looseness. After the test, the hinges still operate smoothly with no obvious wear or damage, verifying their high load-bearing capacity.
Noise and smoothness test
The hinge was mounted on the door, and the noise generated during the door opening and closing process was measured using a sound level meter. At the same time, the smoothness of the operation was evaluated by observing the movement of the door. The test was conducted in a quiet environment to eliminate external interference. The results showed that the noise level was less than 30 decibels and the door moved smoothly, confirming the quiet and smooth operation of the hinge.
Automatic closing function test
The automatic closing function of the hinge was tested by mounting it on the door and observing the closing process. The closing speed was measured, and the accuracy of the closing position was evaluated. The test showed that the door closed smoothly within 3 - 5 seconds and reached the closed position accurately, demonstrating the excellent automatic closing function of the hinge.
Corrosion resistance test
The hinge was placed in a salt spray test chamber for 500 hours in accordance with the ASTM B117 standard. After the test, the hinge surface was checked for any signs of rust or corrosion. The results showed that there was no visible rust or corrosion, indicating that the hinge has high corrosion resistance.
Carbon steel analysis
Carbon steel is an iron-carbon alloy with an iron-based carbon content of 0.02% to 2.11%, and does not contain intentionally added alloying elements. Its performance varies significantly with the carbon content: low carbon steel (carbon content <0.25%) has good plasticity, is easy to weld, and is suitable for stamping; medium carbon steel (0.25% to 0.6%) has balanced strength and toughness and is often used for mechanical parts; high carbon steel (>0.6%) has high hardness and strong wear resistance and can be used to make knives or springs. The advantages are low cost, simple smelting process, and excellent processing performance. It is widely used in construction, machinery manufacturing and other fields, but the disadvantage is that it has poor corrosion resistance and is easy to rust, and needs to be protected by painting, galvanizing, etc.
