Cold rolled sheet has become the main material for manufacturing sofa hinges. The material for sofa hinges is generally cold-rolled sheet, so why should we choose cold-rolled sheet first? Because the cold-rolled plate has a smooth surface and excellent craftsmanship. Has good stamping performance. At the same time, it has good durability, heat resistance, and heat reflectivity. This type of steel plate has a wide range of applications, such as aviation machinery manufacturing and precision instrument manufacturing. Often people write its name incorrectly, as' Cold Tie Plate '. When we manufacture sofa hinges, they require good cold bending and cup effect. Their main purpose is to combine sofa links and adjust the angles of various furniture. Depending on the gear, they are used for different positions of furniture, such as armrests, headrests, backrests, and other joint position adjustments. And cold-rolled sheets happen to have this property.

For sofa hinges, their models vary depending on the sofa, and even for the same model, there are different specifications, mainly reflected in its multiple gear specifications and starting angles. Its surface has undergone processing such as electroplating, powder coating, electrophoresis, etc., Exquisite workmanship. Here are two points to note for everyone:

1. Do not weld directly to inclined areas, as this may cause mechanical failure;

2. Be careful when welding pipes, do not weld to the plastic part inside. When releasing the gear lock, firmly place the rear seat forward, and then place it flat.
