How a Full Servo 3-Piece Baby Pull-Up Diaper Machine Helped a Factory Scale Production with Stability

A Practical Production Solution for High-Volume Baby Pants Manufacturing
As global demand for baby pull-up diapers continues to grow, manufacturers face a familiar challenge:
How do we increase output without sacrificing quality, stability, or operating cost control?
This case study introduces how a customer successfully upgraded their production capacity using Welldone’s Full Servo 3-Piece Baby Pull-Up Diaper Machine (WD-LLK-600-SV) — designed specifically for long-term, high-speed, stable manufacturing.

1️⃣ The Customer Challenge: Growth Pressure from the Market
The customer is a baby diaper manufacturer operating in an emerging market. With expanding distributor orders and retail demand, their existing production line could no longer keep up.
They faced three core problems:
Insufficient capacity to support annual volume growth
Unstable high-speed operation, causing frequent downtime
Material waste and quality fluctuation during long production runs
Their goal was clear:
Build a reliable, high-output pull-up diaper line that could run continuously, with predictable quality and cost control.
2️⃣ Why a 3-Piece Full Servo Pull-Up Diaper Machine?
After evaluating product structure and market positioning, the customer chose a 3-piece baby pull-up diaper design, which offers:
Better fit and comfort for premium baby pants
Strong acceptance in mid-to-high-end markets
Higher brand differentiation potential
To support this structure efficiently, the machine had to meet both speed and precision requirements — which led to the selection of a full servo solution.
3️⃣ The Solution: WD-LLK-600-SV Full Servo Baby Pull-Up Diaper Machine
Welldone supplied the WD-LLK-600-SV, a Full Servo 3-Piece Type Baby Pull-Up Diaper Machine, engineered for high-volume industrial production.
🔧 Key Production Capabilities
Designed Speed: up to 600 pcs/min
Stable Operating Speed: 450–550 pcs/min
Annual Output Capacity: 40–140 million pieces
Passing Rate: ≥ 98% (excluding glue applicator & auto splicing)
This allows the customer to maintain continuous high-speed output without sacrificing consistency.

4️⃣ Stability Comes from Structure, Not Just Speed
Many machines advertise high speed — but stability is what actually protects profits.
The WD-LLK-600-SV achieves this through:
⚙ Full Servo Drive System
Independent servo control for critical modules
Precise synchronization across forming, cutting, and folding units
Reduced mechanical stress during long production runs
🔌 Optimized Energy Design
Installed Power: 350 KW (including glue filter)
Actual Power Consumption: approx. 300 KW
Efficient airflow and power distribution reduce unnecessary energy loss
💨 Industrial Air Management
Air Pressure: 0.6–0.8 Mpa
Air Consumption: 4000 NL/min
Stable pneumatic performance even under continuous operation
5️⃣ Factory Layout & Installation Reality
For large-scale production, space planning matters as much as machine performance.
Machine Size: 35.0m × 2.30m × 3.5m (L × W × H)
Required Working Area: 39m × 9.0m × 5.0m
Total Line Weight: approx. 80 tons
Container Loading: 7 × 40HQ containers
The machine direction can be designed right-to-left or customized based on factory layout.
6️⃣ Production Environment & Operator-Friendly Design
To ensure long-term factory suitability:
Operating Temperature: 10–35°C
Humidity: 55% RH ±5
Noise Level: ≤87 dB (measured at 1 meter)
The machine is fully computerized, with a full servo automatic grade, enabling operators to manage production efficiently with reduced manual intervention.
7️⃣ Results After Commissioning
After installation and commissioning, the customer reported:
✔ More consistent product quality
✔ Significantly lower scrap rate
✔ Improved daily and monthly output stability
✔ Greater confidence in accepting long-term supply contracts
Instead of hiring more labor or running machines beyond safe limits, they scaled production by choosing the right equipment architecture.
8️⃣ More Than a Machine: What Welldone Delivers
Beyond equipment supply, Welldone provided:
Production line planning & layout guidance
Technical commissioning support
Long-term spare parts availability
Raw material compatibility consulting
Responsive after-sales communication
This approach helps customers build sustainable production capacity, not just short-term output.
