Product Overview
The DW-1650 is engineered for packaging plants that require more than standard lamination. It is specifically designed to handle multi-layer corrugated combination jobs, where conventional flute laminators struggle with stability, alignment, and thickness control.
This model is not just a laminator-it is a multi-layer combination system capable of building complex board structures efficiently and consistently.

1. Dual Bottom Feeders + Single Top Feeder Structure
- The core structure is fundamentally different from standard laminators.
- Two independent bottom feeders allow simultaneous feeding of two flute sheets
- One top feeder delivers litho or liner board
- Enables multi-layer combination in one pass
Key capability:
- Two single flutes → 4-ply board
- With top sheet → 5-ply structure
- Maximum up to 8 layers total combination
- This is a clear advantage over traditional single-bottom feeder machines.
2. Designed for Heavy and Multi-Layer Boards
The DW-1650 is built to process:
- A/B/C/E/F flute corrugated boards
- Single, 3-ply, and 5-ply sheets
- Grey board and thick substrates up to 10 mm
- The reinforced feeding and pressing system ensures stable transport even with thick, rigid, or large-format boards.
3. Stable Output at 5000 Sheets/Hour
With a production capacity of up to 5000 sheets/hour, the machine focuses on:
- Consistent output rather than peak speed fluctuation
- Stable performance for complex lamination jobs
- Reduced downtime when handling multi-layer materials
- This makes it suitable for factories prioritizing reliability over extreme speed.
4. Servo Alignment System for Multi-Layer Accuracy
A servo-controlled aligning unit ensures precise positioning between layers:
- Real-time correction between top and bottom sheets
- Maintains lamination accuracy within ±1.5–2 mm
- Minimizes misalignment even with uneven or warped materials
- Compared to mechanical alignment systems, this provides higher consistency across long runs.
5. Wide Material Compatibility
The machine supports a broad range of materials:
- Top sheet: 120–800 gsm
- Middle layer: 300–800 gsm flute
- Bottom/substrate: up to 10 mm thickness
- This flexibility allows production of:
- Heavy-duty cartons
- Industrial packaging boards
- Reinforced corrugated structures
6. Reinforced Mechanical Structure
To support multi-layer lamination, the machine adopts:
- Heavy-duty frame construction
- High-load transmission system
- Precision-machined components
- This ensures:
- Long-term durability
- Reduced vibration during operation
- Stable pressure across wide sheets
7. Optimized for Large Sheet Processing
With a maximum working size of 1650 × 1450 mm, the DW-1650 is suitable for:
- Large-format packaging
- Industrial carton production
- Bulk order processing
The feeding and alignment system is calibrated for wide-sheet stability, which is often a weak point in standard machines.
Working Principle
- Two bottom sheets are fed simultaneously through independent feeders
- Top sheet is delivered separately and synchronized with bottom layers
- Servo alignment system corrects positioning between all layers
- Adhesive is applied evenly across bonding surfaces
- Sheets are combined and pressed to form multi-layer structures
- Finished laminated boards are output for downstream processing
This process allows multi-layer construction in a single pass, significantly improving efficiency compared to step-by-step lamination.
Machine Advantages
1. Multi-Layer Combination in One Operation
Unlike standard flute laminators that handle only 2-layer bonding, this machine:
- Combines multiple layers simultaneously
- Reduces processing steps
- Improves overall production efficiency
01
2. Strong Capability for Thick Board Production
Designed for heavy-duty applications:
- Handles thick and rigid materials smoothly
- Maintains alignment under high load
- Suitable for industrial-grade packaging
02
3. Reduced Labor and Handling
By completing multi-layer lamination in one pass:
- Fewer operators required
- Less intermediate handling
- Lower risk of material damage
03
4. Consistent Quality Across Complex Jobs
The combination of servo alignment and stable feeding ensures:
- Uniform bonding
- Reduced waste
- Consistent finished board quality
04
5. Flexible Production Applications
The DW-1650 can function as:
- A multi-layer combination laminator
- A standard flute laminator for regular jobs
- This dual functionality increases machine utilization.

FAQ
Q1: What makes the DW-1650 fundamentally different from a standard flute laminator?
A: The DW-1650 uses a two bottom feeders + one top feeder configuration, allowing multi-layer combination in a single pass. Most standard laminators only bond two sheets; this machine builds 4-ply, 5-ply, and even up to 8-layer structures directly.
Q2: What kind of production capacity can users expect?
A: Stable output up to 5000 sheets per hour, optimized for multi-layer jobs where consistency is more critical than peak speed.
Q3: What types of boards can it process?
A: It handles A/B/C/E/F flute corrugated boards, grey board, and heavy paperboard up to 10 mm thickness, including single, 3-ply, and 5-ply materials.
Q4: How does it perform with thick or warped materials?
A: The dual bottom feeder system ensures independent and stable feeding, even for warped or heavy boards-something single feeder machines struggle with.
Q5: How accurate is the lamination?
A: Controlled by a servo aligning unit, maintaining accuracy within ±1.5–2 mm, even in multi-layer combinations.
Q6: What is the main advantage of the dual bottom feeder design?
A: It allows simultaneous feeding of two flute sheets, enabling direct formation of multi-layer boards without secondary processing.
Q7: How does this impact production efficiency?
A: It eliminates intermediate steps. Instead of laminating layer by layer, everything is combined in one continuous operation, reducing time and labor.
Q8: What is the working principle of the machine?
A:● Two bottom sheets are fed independently
● Top sheet is synchronized above
● Servo system aligns all layers in real time
● Glue is applied uniformly
● Layers are pressed and bonded in one pass
Q9: How does the machine ensure stable alignment across multiple layers?
A: Through servo-driven correction between layers, rather than relying on fixed mechanical positioning.
Q10: Is it suitable for large sheet sizes?
A: Yes, with a maximum size of 1650 × 1450 mm, designed for large-format packaging production.
Q11: What about long-term durability?
A: The machine features a reinforced heavy-duty frame and high-load transmission system, built for continuous industrial operation.
Q12: How does it compare to high-speed laminators like 12000 sheets/hour models?
A: High-speed models focus on volume. The DW-1650 focuses on multi-layer capability and structural lamination, which those machines cannot achieve.
Q13: What type of products is it best suited for?
A:● Heavy-duty export cartons
● Reinforced corrugated packaging
● Multi-layer industrial boards
● High-strength packaging structures
Q14: Can it also run standard lamination jobs?
A: Yes, it can operate as a regular flute laminator, offering flexibility when multi-layer production is not required.
Q15: How does it reduce labor cost?
A: By combining multiple layers in one pass, it reduces:
● Manual handling
● Re-feeding steps
● Operator dependency
Q16: What is the advantage in terms of material handling?
A: Fewer transfers between processes mean lower risk of board damage and deformation, especially for large sheets.
Q17: How stable is the machine during continuous production?
A: Designed for low vibration and consistent pressure, ensuring uniform bonding over long production runs.
