In modern ergonomic sleep systems, pocket spring cores have outpaced traditional Bonnell matrices due to superior motion isolation, body contouring, and multi-zone support. Producing millions of individually pocketed coil strings requires ultra-fast wire coiling, instant thermal tempering, continuous ultrasonic non-woven bag sealing, and high-speed adhesive matrix gluing without core deformation.
This comprehensive technical guide evaluates Infinity Machinery's high-efficiency pocket spring machinery suite. By deploying the IF-P180-1 Single Wire High-Speed Pocket Spring Machine, the IF-P130-2 Double Wire Pocket Spring Machine, and the IF-PPA Fully Automatic High-Speed Pocket Spring Assembly Line, mattress factories achieve production rates of up to 180 pocketed springs per minute with zero non-woven fabric tearing.
To satisfy global demand for pocket spring cores, traditional single-wire coiler speeds are no longer sufficient. The IF-P130-2 Double Wire Pocket Spring Machine doubles output capacity by running two independent coiling channels, heat treating stations, and ultrasonic non-woven fabric baggers simultaneously at 130 pcs/min.
Dual wire payoff reels feed 1.6 - 2.3 mm high-carbon wire through twin CNC coiling cams. Inline electric tempering units apply instantaneous heat treatment to eliminate internal coiling stress.
Continuous non-woven fabric (60-100 g/m²) is folded and ultrasonically seam-welded around each compressed coil. Ultrasonic horns form tight, noise-free fabric pockets without messy liquid adhesives.
For factories demanding maximum single-channel speed, rapid multi-zone spring pattern switching, and compact floor space utilization, the IF-P180-1 Single Wire High-Speed Pocket Spring Machine delivers an industry-leading coiling speed of up to 180 pcs/min.
Once individual pocket spring strings are produced by the coiler, they must be assembled into full mattress core units. The IF-PPA Fully Automatic High Speed Pocket Spring Assembly Machine feeds spring strings, applies hot-melt adhesive lines, compresses string rows together, and cuts finished core lengths automatically.
Precision PID-controlled hot-melt glue nozzles apply continuous or intermittent glue lines across non-woven pockets, bonding adjacent rows securely within 2 seconds.
Supports both linear parallel alignment and honeycomb nested row patterns for high coil-density luxury orthopaedic mattress cores.

The IF-P180-1 operates at a record-breaking 180 springs per minute on a single coiling channel, maximizing output per square meter of factory floor space while providing fast wire gauge changeovers.
Ultrasonic horn generators convert high-frequency electrical energy into localized mechanical vibrations (20 kHz). This melts non-woven thermoplastic fibers instantaneously at seam points without thermal burning or charring associated with heated sealing bars.
Yes. The IF-PPA controller syncs string intake from multiple coiler channels, automatically arranging firmer wire gauge strings (e.g. 2.0mm) in lumbar zones and softer wire gauge strings (e.g. 1.8mm) in shoulder zones.
