Setting up a pocket spring mattress production line that actually delivers ROI is harder than it looks. Most factories struggle with low output, inconsistent spring quality, and high labor costs. This guide walks through a real Vietnam factory case using IF-P180-2 and IF-T4 — and how they cut labor by 60% while doubling output.
A pocket spring mattress production line should be a money printer. Instead, most factories fight constant jams, uneven spring tension, and scrap waste. The root cause is almost always the same: mismatched machines not designed to work together.
When your spring coiling machine runs at 180 springs/min but your assembly machine handles only 120 units/hour, you have a bottleneck. This guide shows how to size each machine so the whole line flows smoothly.
We walk through a real Vietnam factory — 6 machines, 8 operators, 400 mattresses/day. By the end, you will know exactly what to buy and how to lay it out.
The IF-P180-2 is a high-speed pocket spring machine for continuous production. Key specs:
What makes IF-P180-2 special is the buffer conveyor. Spring strings accumulate on a powered conveyor so the assembly machine can pull at its own pace without stopping the coiler.
The IF-T4 spring assembly machine takes spring strings and assembles them into a complete spring unit. Key specs:
| Metric | IF-P180-2 + IF-T4 Line | Manual Assembly |
|---|---|---|
| Operators per 400 mattresses/day | 8 people | 20 people |
| Spring consistency (CV%) | < 3% | 15-25% |
| Setup change time | 15 minutes | 2-3 hours |
| Scrap rate | < 2% | 8-12% |
| Payback period | 14 months | N/A |
Good layout minimizes material handling. In the Vietnam factory, the layout is:
Total space: 35m x 15m. Power: 3-phase 380V, 60A.
Since 2009, Infinity has installed 500+ lines in 30+ countries.
Our engineers design your line based on your factory dimensions and output targets.
Technicians available for on-site installation in Asia, Middle East, South America, Africa.
Instant troubleshooting via WhatsApp + video call. Most issues resolved in <30 minutes.
The Vietnam factory installed a 6-machine line in March 2026:
The biggest mistake is sizing each machine in isolation. Design for flow: match each machine output to the slowest machine. Add buffer conveyors. Train operators on all machines.

Q: How long does installation take?
A: Typically 7-10 days for a complete 6-machine line, including training.
Q: What power supply is required?
A: 3-phase 380V, 60A main breaker. We can advise on electrical layout.
Q: Do you provide spare parts?
A: Yes, we recommend keeping a 3-month spare parts kit. We ship internationally.
Q: Can I add more machines later?
A: Yes, the layout is designed to be expandable. Just leave space for future machines.
