8.Is the cushioning system of the WNEE split-type damping hinge replaceable, and how about the after-sales cost?
Hello, the cushioning integrated damper of the WNEE split-type damping hinge is replaceable. Its springs and dampers are removable and replaceable, so the after-sales cost is low. While the universal hydraulic buffer system of the traditional one-piece hydraulic hinge is irreplaceable, and its power and cushioning systems are not removable, leading to high after-sales cost.
-
9.How does the WNEE split-type damping hinge perform in terms of oil leakage, and what's the difference compared to traditional hinges?
Hello, the WNEE split-type damping hinge adopts an oil-free power chamber, so there is no oil leakage. The traditional one-piece hydraulic hinge has an oil-filled power chamber, which has the risk of oil leakage.
-
10.Where is the low after-sales cost of your company's hinge reflected, and what's the difference from traditional hydraulic hinges?
Hello, when after-sales problems occur with traditional hydraulic hinges, professional technicians are required to repair them on-site or even replace the entire hinge, resulting in high costs. However, the split-type damping hinge of our company allows for easy disassembly and replacement of parts such as springs and dampers. Ordinary people can handle it quickly according to the process, without the need for professional technicians to come to the site or replace the entire hinge. Therefore, the after-sales cost is very low.
-
11.How to switch between the first and second stage forces of the hinge, and is the operation complicated?
Hello, you only need to adjust the amount of pre-pressing screws pressed in to switch freely between the first and second stage forces, and the operation is very simple.
-
12.What functions does this hinge have and what needs can it meet?
Hello, it is a four-in-one functional design, integrating the functions of a door closer, hinge, door stopper, and positioner. It can also freely switch between the first and second stage forces, enabling perfect movements such as door leaf buffering, positioning, and door closing, fully meeting the usage needs of doors.
