A pocket spring coiling machine like the IF-P130-1 automatically forms steel wire into individual pocket springs, wraps each spring in non-woven fabric, and heat-treats them for optimal elasticity. The machine produces 130 springs per minute, with each spring individually encased in its own fabric pocket.
Pocket spring machines (IF-P130-1, IF-P180-2) produce individually wrapped springs that move independently, providing better motion isolation and personalized support. Bonnell spring machines (IF-B90) produce hourglass-shaped springs that are interconnected, offering more traditional support at a lower cost.
| Feature | Pocket Spring | Bonnell Spring |
|---|---|---|
| Motion Isolation | Excellent | Moderate |
| Price Point | Higher | Lower |
| Target Market | Premium/Mid-range | Budget/Hotel |
The IF-P130-1 produces 130 pocket springs per minute, which translates to approximately 7,800 springs per hour. For an 8-hour shift, that's over 62,000 springs — enough to equip 75-100 queen-size mattresses daily. The IF-P180-2 double-wire model reaches 180 springs per minute.
Pocket spring machines (IF-P130-1, IF-P180-2) handle wire diameters from 1.6mm to 2.3mm. Bonnell spring machines (IF-B90) typically use 1.8mm to 2.4mm wire. The IF-P130-1 produces springs with a core diameter of 55-72mm and height range of 80-250mm.
The IF-P130-1 consumes an average of 22 KWH, while the IF-P180-2 uses 26 KWH. A key advantage of these machines is their full mechanical drive system — they require minimal air supply (0.02m³/min at 0.8MPa), eliminating the need for a dedicated air compressor. This reduces both electricity costs and maintenance requirements compared to pneumatic machines.
Pocket spring machines use non-woven fabric with a weight of 60-100 g/m². The fabric width ranges from 380-700mm for the IF-P130-1 and 300-700mm for the IF-P180-2. Higher quality non-woven (80-100 g/m²) produces more durable pockets that resist tearing during assembly and use.
For a factory producing 100 queen-size mattresses per day (700 springs each), switching from buying springs at $0.90/unit to in-house production at $0.30/unit saves approximately $42,000 per month in spring costs alone. After accounting for raw materials, labor, and maintenance, the typical payback period is 3-6 months.
| Cost Factor | Buying Springs | In-House (IF-P130-1) |
|---|---|---|
| Cost per Spring | $0.90 | $0.30 |
| Daily Springs (70,000) | $63,000 | $21,000 |
| Monthly Savings | — | $42,000 |
The IF-P130-1 requires 1-2 operators per shift. The machine's CNC control system and automatic error detection minimize manual intervention. For a complete pocket spring production line (coiling + assembly), you'll need 2-3 operators total. The IF-B90 Bonnell coiler also operates with 1-2 operators.
The IF-P130-1 measures 6000 × 1700 × 2200mm (approximately 10.2 m²). The IF-P180-2 is larger at 7000 × 2400 × 2200mm. Plan for a total area of 15-20 m² including raw material storage and finished spring output. The compact design of the IF-P130-1 makes it ideal for factories with limited space.
Choose the IF-P130-1 if you produce standard pocket spring mattresses and need a cost-effective, space-saving solution. Choose the IF-P180-2 if you need multi-zone mattress capability (different firmness levels in different areas) or higher production volumes (180 vs 130 springs/min).
| Feature | IF-P130-1 | IF-P180-2 |
|---|---|---|
| Wire Input | Single Wire | Double Wire |
| Speed | 130 pcs/min | 180 pcs/min |
| Multi-Zone | No | Yes |
| Power | 22 KWH | 26 KWH |
| Footprint | 6000×1700mm | 7000×2400mm |
Yes. A coiling machine (IF-P130-1) produces individual pocket springs, while an assembly machine (IF-PPA) takes those springs and assembles them into complete pocket spring units for mattresses. Together, they create a complete in-house production solution. The IF-PA is a semi-automatic option for smaller factories.
The IF-BA is a standalone Bonnell spring assembling machine that connects springs into units. The IF-BPL100 is a complete integrated production line that combines wire straightening, spring coiling, and unit assembly into one continuous flow. The BPL100 is ideal for high-volume production (60-80 springs/min), while the BA is better for smaller factories or as a supplement to existing equipment.
Infinity Machinery provides comprehensive installation and training support. The IF-P130-1 CNC control system is intuitive, and operators typically become proficient within 2-3 days of training. Pre-programmed parameters for common spring sizes make setup quick and consistent. Delivery time is 10-20 working days.
