The difference between primary force hinge and secondary force hinge is as follows:
1, structural material
The first stage hydraulic hinge adopts single-sided torsion spring, and the second stage hydraulic hinge adopts double-sided torsion spring and patented double bearing structure.
2. Influence
The force hinge is either completely closed or completely opened; The two-stage stressed hinge can be opened and closed freely, which can open the door panel 1 10. When closing the door, the door panel can stay at any angle within the range of110 to 45, and the front door panel will automatically close slowly after 45.
3. Persistence
A force hinge will have the problem of prying back and forth, and the number of opening and closing will be more, and the wooden screws will slip and loosen, which will affect the normal use of furniture and cabinets. It will also cause damage to furniture; The two-stage force hinge will not have the problem of prying back and forth, and it is durable and has low noise.
