Sofa Pocket Spring
1、Before packaging, the springs are compressed to about two-thirds of their initial length, effectively increasing the initial tension as well as providing a good resilient comfort that is steady over time.

2、The ultrasonic side-sealing technique does not fully compress springs, thereby ensuring their individual movement without interference.
3、High-density distribution makes it possible to transfer the load uniformly to a number of spring units. This way, they become perfect for the sofa cushions that are used most of the time. -
Hot
Zoned Independent Pocketed Coil
1. Double wire feeding zones are applied in the process with different wire diameters for clearly differentiated support zones.

2, Durability is improved by overall heat treatment, as the product is able to pass 100,000 cycles without any visible deformation.
3, The sewing of the fabrics to each other is achieved by ultrasound welding of the edges, which removes the ability to be torn by wear and aging of the cotton fabrics. -
Mini Independent Pocketed Coil
1、One of the main features of the pocket coil is the small diameter of the wire and close spacing. By installation 400-600 springs per square meter, this method achieves a very dense distribution of support points.

2、A wire diameter of 0.9mm-1.6mm is chosen in order to make the spring softer and more responsive. Such a spring is able to follow body shape and therefore is suitable for comfort layer of a mattress.
3、In most cases, they are working together with the main support springs to form a double-layered composite structure. -
Pocket Spring Unit
1、Each spring is individually wrapped with a nonwoven fabric pouch, allowing each spring to move freely and therefore the vibration transfer is effectively reduced.

2、These springs made of high-grade carbon-manganese steel wire last 2-3 times longer than regular steel springs and they are not easily deformed.
3、By employing high-precision automatic winding machines, the height and number of coils of the springs can be controlled within a tolerance of ±2mm to ensure consistent dimensions.
