Stiffness Control Of Pocket Springs
1. The number of coils: the hardness of the spring is controlled by the number of coils of the spring, the general
number of independent pocket springs is 5.5-10 coils
2. Wire diameter: the thickness of the wire diameter also determines the hardness of the spring, upholstered
furniture commonly used pocket spring wire diameter of 1.0-2.3mm.
3. Degree of compression: The springs have a certain degree of compression when encapsulated in the bag;
the more compression, the higher the overall firmness of the spring. This method effectively reduces the overall
weight and cost of the mattress.
4. Overall density: The density of the spring arrangement also determines the overall hardness of the bed net,
the higher the density, the greater the hardness, the corresponding comfort is higher, the disadvantage is that
the weight is large, high cost.
5. Quality Impact:Heat treatment process: Heat treatment of springs affects spring performance and service life,
and precise control of temperature and cooling time during heat treatment is critical.
6. Steel wire quality: The specification, quality and strength of the steel wire directly affects the quality of the spring.
7. Fabric quality: The thickness of the non-woven fabric, grams per unit area, processing technology, raw materials,
etc. affect the service life of independent pocket springs.
8. Welding and bonding quality: the ultrasonic welding technology directly affects the strength of the weld and the
integrity of the package. The uniformity of the weld, the temperature of the adhesive and other factors affect the
bond, which directly affects the life of the entire pocket spring bed net.
