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.
