When upgrading your post-press packaging line, selecting the right window patching machine is critical. At Fengchi, we offer three models: Model P, Model Q, and Model Y.
All three series are full-servo window patching machines built for folding carton and cardboard packaging production. How do you know which one is the perfect fit for your factory? Here is a quick guide.

Model P: The Flat Window Specialist
If your primary focus is high-volume, standard packaging, the Model P is your most cost-effective workhorse.
- Best For: Tissue boxes, bakery boxes, and standard retail cartons.
- Key Advantage: It is optimized for seamless flat patching. Its streamlined design means faster setup times and lower maintenance costs.
- Ideal Buyer: Factories looking for a dedicated, high-speed solution for flat window applications.

Model Q: Premium Creasing and V-Cut
Luxury packaging requires extra steps. The Model Q takes standard window patching to the next level by integrating creasing and V-cutting directly into the machine.
- Best For: Premium cosmetic boxes, high-end toy packaging, and complex die-cuts.
- Key Advantage: Eliminates the need for separate creasing machinery, saving floor space and reducing handling errors.
- Ideal Buyer: Printers and packaging manufacturers dealing with rigid boxes and premium retail goods.

Model Y: The Ultimate All-In-One Solution
Why choose one when you can have it all? The Model Y is our multi-functional powerhouse designed for maximum versatility.
- Best For: Contract packagers and factories with highly diverse, small-batch orders.
- Key Advantage: Combines flat window patching, V-cutting, and creasing in a single machine. Switch between jobs instantly via the touchscreen HMI.
- Ideal Buyer: Businesses that need to future-proof their production line and handle multiple SKUs without buying multiple machines.

The table is a decision shortcut, not a substitute for a technical comparison with your own job mix. A packaging plant running mostly simple tissue box windows will not use a Y machine the way a high-volume pharmaceutical carton printer will.
How to Choose the Right Window Patching Machine
Work through these six questions with your production manager and your current job mix instead of memorizing specification sheets.
What is the difference between Model P, Q and Y window patching machines?
Model P is built for high-speed flat windows and tissue boxes with one-touch setup. Model Q adds creasing and V-cut versatility with digital feed, glue, and film settings. Model Y is the all-in-one ultra-high-speed series with full-servo bus control and 3-zone paper feeding.
What windows do you actually run?
List the window styles from your last 12 months of orders. Flat windows and tissue boxes point to Model P. Creased or V-cut windows point to Model Q or Model Y. A mix of all three points to Model Y.
What is your sustained throughput?
Peak speed matters less than the speed you can hold all day. High sustained volume favors the Y series continuous rate and 3-zone feeding; shorter runs may favor setup speed and simplicity.
How often do you change jobs?
Changeover time is a hidden cost. One-touch setup helps on dedicated runs, digital presets help when recurring jobs come back, and full automation helps when the line must move through mixed formats.
What sheet sizes do you need?
Match machine width to your largest carton blank. The 760, 950, and 1100 mm versions cover most folding carton work, and the 1400P extends the range for larger sheets.
What is the total cost of ownership?
Compare purchase price, tooling, changeover waste, energy use, spare parts, and service.
