Full-Servo Sanitary Napkin Production Line (WD-KY-1000-SV)

A plain-English guide for first-time factories—what the specs mean and how to get started


Who this is for

If you’re building your first sanitary napkin plant, you need equipment that is fast and forgiving, with clear requirements and predictable costs. Below we translate the WD-KY-1000-SV specification into practical decisions you can act on—site prep, staffing, utilities, ramp-up, and ROI.


What the line actually does

WD-KY-1000-SV is a full-servo sanitary napkin line. “Full servo” means each critical station has its own servo motor and motion profile. In practice, you get:

  • Stable registration at speed (cuts visual defects).

  • Recipe-based changeovers (fewer manual tweaks, faster size change).

  • Better repeatability shift to shift (easier to train a new team).

It converts your raw materials—topsheet, pulp/SAP core or air-laid/SAP paper, backsheets, release papers, pouch film, easy tape—into finished pads, including fluff core, ultra-thin, and triple-type with leakage barriers, with or without wings and easy-pack presentation.wd-ky-1000-sv-full-servo-sanitary-napkin-production-line

Performance at a glance (what the numbers mean)

  • Design speed: 1,000 pcs/min (≈250 m/min)

  • Stable operating speed: ~800 pcs/min (reference 240 mm, ≈200 m/min)

  • Qualified pass rate: ≥97% (excludes external glue applicator & auto-splicing)

  • Annual volume: 90–240 million pads (depends on SKUs, shifts, and packaging)

Why it matters for a first plant:
Running 800 pcs/min at ≥97% means you turn more minutes into sellable pads and waste less material—especially important while your operators are still learning.


Utilities, footprint & logistics (so you can plan the site)

  • Power supply: 3-phase, 5-wire, 380 V / 50 Hz

  • Installed power: 450 kW (incl. glue filter) | Typical running load: ~400 kW

  • Main cables: 3×120 mm² + 1×50 mm² + 1×25 mm²

  • Compressed air: 0.6–0.8 MPa, demand ~4000 Nl/min

  • Machine body: 28.0 m × 2.5 m × 3.0 m (L×W×H)

  • Recommended working space: ≈40.08 m × 9.0 m × 5.0 m (includes aisles & service)

  • Line weight: ~50 tons (whole line)

  • Shipping: 4 × 40 HQ containers

  • Ambient conditions: 10–35 °C, 55% RH ± 5%, ≤87 dB at 1 m

What to do next: share your floor plan and power/air drawings; we’ll return a scaled layout with operator positions and material flow so construction and wiring can proceed without rework.


Product formats supported

  • Fluff core pads: topsheet, fluff core (with SAP), backsheet, back & wing release papers, pouch film, easy tape.

  • Ultra-thin pads: topsheet, air-laid, SAP paper, backsheet, release papers, pouch film, easy tape.

  • Triple-type / leakage-barrier pads: side barriers for better anti-leak performance.

  • Sizes: as required (we supply recipe templates for your target SKUs).


What the specs mean for your P&L (startup math)

Scenario (conservative):

  • Speed 800 pcs/min, pass rate 97%776 good pads/min.

  • Compared with a 95% pass rate, you save +16 pads/min960 pads/hour fewer rejects.

  • Multiply by your material cost per pad and daily hours; the weekly savings typically exceed the cost of several “optional” modules. In early months, this difference is often the gap between break-even and profit.


Why full-servo helps first-time teams

  1. Shorter learning curve – operators recall a recipe rather than “dial by feel.”

  2. Cleaner changeovers – less trim waste, quicker restarts, steadier OEE.

  3. Traceability-ready – stable motion makes it easier to tie lots/parameters in MES or a simple barcode log.

  4. Future-proof – servo stations can be tuned as raw materials or SKUs evolve.


Ramp plan you can hand to the floor (first 90 days)

Day 0–30 – Make it stable

  • Bring power/air online; verify ambient temp & humidity.

  • Run materials trials to lock CPPs (web tension, glue add-on, nip pressure, sealing temp/time, rotary phase).

  • Publish Recipe v1 and a first-article checklist; enable hourly SPC checks.

Day 31–60 – Make it repeatable

  • Hold ~800 pcs/min at ≥96–97% pass rate.

  • Train a second shift on recipes; start daily OEE and waste reviews.

  • Implement incoming AQL and batch barcodes for traceability.

Day 61–90 – Make it efficient

  • Trim changeover minutes and trim waste; push speed only inside guard bands.

  • Freeze SOPs, maintenance intervals, and critical spares list.

Staffing guideline: 4–6 people/line (line chief, 2–3 operators, QC, maintenance).


Commercial & delivery terms (clear expectations)

  • Origin: China | Trademark: WD Machinery

  • Model: WD-KY-1000-SV | Minimum order: 1 set

  • Automation level: Full Servo (computerized control)

  • Trade terms: FOB Xiamen Port

  • Payment: T/T

  • Delivery: 120 working days after receiving 30% deposit

  • Packing: Anti-rust oil + full PE film wrap + seaworthy wooden case

We confirm machine color and running direction (default Right→Left, customizable) before manufacturing. Product size range is built to your request.


Practical tips for new factories

  • Start with 2–3 SKUs. Fewer changeovers = faster learning, steadier cash flow.

  • Pick suppliers with matching specs. For nonwovens, align GSM / MD-CD tensile / softness to your pad tier; for SAP/air-laid, match absorbency targets to pad length and brand position.

  • Instrument the basics. A simple barcode log (lot + shift + recipe) is enough to start; you can scale to MES later.

  • Budget the utilities. 400 kW running load + 0.6–0.8 MPa compressed air are the two big numbers—size your power line and compressor accordingly.

  • Protect the work environment. Hold 10–35 °C, ~55% RH to keep paper and nonwovens stable; it directly improves pass rate.


Why this line fits a first plant

  • Speed headroom (design 1000) with a realistic stable point (≈800) to master operations before you chase records.

  • High pass-rate target (≥97%) so waste stays predictable.

  • Clear utilities & footprint to avoid “surprise” changes on site.

  • Shipping plan known (4×40HQ) and documents ready (CE/ISO, drawings, manuals, FAT/SAT checklists).

  • Customization on sizes, colors, and line direction so your brand look & workflow match.
