How Do You Ensure Quality Control in Mattress Spring Production?

Mattress complaints often start with the springs—noisy, uneven, or sagging. That’s not a sales problem. It’s a quality control issue.

We ensure quality in mattress spring production through raw material checks, machine calibration, in-process testing, and strict inspection protocols.

If you’re running a mattress factory or buying machines, these quality steps are non-negotiable.

Why Does Raw Material Inspection Matter So Much?

Quality starts at the coil.

Steel wire is the backbone of every mattress spring. If it’s too soft, too brittle, or inconsistent in diameter—you’ll face problems down the line.

Here’s what we check:

Property	Why It Matters	How We Test
Tensile strength	Prevents sagging or snapping	Pull testing (min 1700 MPa)
Diameter consistency	Ensures uniform coil dimensions	Laser micrometer
Surface condition	Avoids rust, noise, breakage	Visual and touch inspection

We reject any batch that doesn’t meet spec. You should too.

What Role Do Certified Suppliers Play?

Certified suppliers aren’t just “nice to have”—they’re your insurance policy.

We only buy wire from ISO 9001-certified factories. Why?

Because:

Their production is traceable
They can issue a material test report
Their quality systems are audited yearly

We also run quarterly audits on our suppliers. We visit, check their process, and verify that their test data matches our in-house results.

Don’t wait for customer complaints to find out you bought bad wire.

Can Machines Really Control Quality?

Yes—but only if you calibrate them properly.

Spring coiling machines must be accurate to ±0.5mm. Otherwise, your mattress will feel uneven or collapse early.

How we ensure precision:

Weekly coil diameter checks with digital calipers
Tension control sensors for wire feed
Software auto-calibration before every shift

Failed springs go to the scrap bin—not to your customers.

We also include a QC label with batch number, date, and inspector name inside each roll.

How Do You Use Customer Feedback to Improve?

You can’t improve what you don’t track.

Call key customers monthly for spring feedback
Collect failure returns and inspect root cause
Update SOPs when the same issue happens 3+ times

For example, after two clients flagged noisy coils, we found one wire supplier had microscopic surface rust. We switched immediately.

Real-world use is your best test lab.

Conclusion

Quality control in mattress spring production isn’t a one-time fix. It’s a system of materials, machines, people, and checks—working together every shift.

If you get it right, you’ll reduce returns, increase repeat customers, and protect your brand.

That’s what quality really delivers.
