Why do cushioning hydraulic hinges quickly lose their cushioning effect? _Hinge knowledge 3

In recent times, there has been a surge of online inquiries directed towards our factory regarding hydraulic hinges. During these discussions, we have come across numerous customers who have experienced issues with the cushioning hydraulic hinges losing their effectiveness too quickly. They have sought information about the cushioning capabilities of the hinges produced by our factory. It's a problem that many people encounter. Some may have purchased expensive hinges, only to find that they offer the same, if not worse, damping effect compared to ordinary hinges. Hinges play a crucial role in furniture as they are opened and closed multiple times a day. The quality of hinges significantly impacts the overall furniture experience. Hydraulic hinges provide an automatic and silent door closing mechanism, enhancing the harmony and warmth of a space while adding a touch of sophistication to furniture and kitchen cabinets. With affordable prices, hydraulic hinges have become a popular choice. However, the increasing number of manufacturers entering the market has resulted in fierce competition, leading some to compromise on quality. This has resulted in issues with the hinges. Some manufacturers sell hydraulic hinges without even conducting quality inspections, which disappoints consumers and erodes their trust in this product. The lack of cushioning in hydraulic hinges is primarily caused by oil leakage in the hydraulic cylinder's seal ring, resulting in cylinder failure. Despite some manufacturers resorting to cost-cutting measures, there has been considerable improvement in the quality of hydraulic hinges over the years (excluding those produced by manufacturers cutting corners). The evolved hydraulic hinges offer superior functionality and durability. Therefore, choosing a reliable manufacturer of hydraulic hinges can significantly enhance the quality and aesthetics of furniture. But how can one ensure selecting the right hydraulic hinge and avoid unnecessary troubles? A buffer hydraulic hinge is designed to utilize liquid's buffering performance, offering an ideal cushioning effect. It consists of a piston rod, housing, and piston with through holes and openings. When the piston rod moves the piston, liquid flows from one side to the other through the through holes, buffering any impact. The buffer hydraulic hinge has gained popularity due to its human-centric approach, soft and silent operation, and the prevention of accidents caused by finger pinching. As the user base grows, so does the number of manufacturers, resulting in a flood of substandard products. Many consumers have reported that their hydraulic hinges lose their functionality shortly after purchase. Even expensive buffer hydraulic hinges fail to outlast ordinary hinges, leaving users feeling disheartened. This situation echoes what happened a few years ago with alloy hinges. Consumers turned a blind eye to alloy hinges due to their poor quality, preferring the sturdier iron hinges. Consequently, the market for alloy hinges diminished. Therefore, it is crucial for buffer hydraulic hinge manufacturers to prioritize consumer satisfaction over short-term gains. In an era of information asymmetry, where consumers struggle to differentiate between good and bad quality, manufacturers bear the responsibility of ensuring product quality, leading to a win-win situation for both the market and profits. The quality of a hydraulic hinge depends on the sealing of the piston, which is not easily discernible in the short term. To choose a high-quality buffer hydraulic hinge: 1. Pay attention to the appearance. Manufacturers with mature technology prioritize the appearance, ensuring well-handled lines and surfaces with minimal deep scratches. This is a hallmark of skilled manufacturers. 2. Check the consistency of door closing speed. Observe whether the buffer hydraulic hinge feels stuck or produces unusual sounds. A significant difference in closing speed should alert you to possible discrepancies in the hydraulic cylinder selection. 3. Assess the anti-rust capabilities. The rust resistance can be determined through salt spray testing, where high-quality hinges rarely exhibit signs of rust after 48 hours. However, be cautious of fraudulent claims that boast about passing extensive tests, such as opening and closing the hinge over 200,000 times or subjecting it to salt spray testing for 48 hours. Many profit-driven manufacturers release products to the market without conducting any tests at all. Consumers often encounter hinges that lose their cushioning functionality after minimal use. Therefore, beware of deception. Given the current technical level in the industry, achieving a fatigue test of 100,000 opening and closing cycles is unrealistic. Domestic manufacturers can realistically reach a fatigue test level of 30,000 cycles. Lastly, once you acquire a hydraulic hinge, you can forcefully accelerate the closing speed or install it on a cabinet door and close it forcefully instead of relying on automatic closure. Poor-quality cushioning hydraulic hinges tend to close quickly and may exhibit oil leakage or, in extreme cases, explode. If you encounter any of these issues, it's time to bid farewell to the problematic buffer hydraulic hinge.
