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.
