The **Dongfang (often branded as "DF" or "Dong Fang")** four-color printer slotter die cutter is a classic workhorse in the corrugated box industry, particularly popular in Asia and emerging markets. Let's break down what this machine does and how it operates.

---

## **What is a Dongfang 4-Color Printer Slotter Die Cutter?**

It's a **highly versatile, semi-automatic to fully automatic machine** that combines three critical functions into one production line:
1. **Printing** (Flexographic, 4 colors)
2. **Slotting & Creasing** (for standard box shapes)
3. **Die-Cutting** (for custom shapes, using a **flatbed die**)

This "all-in-one" design makes it ideal for small to medium box factories that need to produce a wide variety of orders without changing machines.

## **How It Works In Action (Step-by-Step)**

Imagine a **60-100 foot long production line** with operators at key stations.

### **1. Feeding Station**
* An operator (**feeder**) places a stack of pre-cut corrugated sheets onto the feeding table.
* A **suction cup feeder** (automatic or manual-assisted) lifts one sheet at a time and places it onto the conveyor belt.
* **Visual:** Sheets are fed in rhythm, like a steady heartbeat.

### **2. Printing Unit (4 Colors)**
* The sheet travels through up to **4 consecutive flexographic printing stations**.
* Each station has:
* **Printing Cylinder:** Mounted with a flexible photopolymer printing plate.
* **Anilox Roll:** Transfers a precise amount of ink from the ink pan to the plate.
* **Impression Cylinder:** Presses the corrugated sheet against the inked plate.
* Colors are typically applied in sequence: **Cyan → Magenta → Yellow → Black** (CMYK process), or any spot colors.
* Between colors, **dryers** (hot air or IR) flash-dry the ink to prevent smearing.

### **3. Slotting & Creasing Unit**
* After printing, the sheet passes through the **slotting section**.
* **Rotary slotting knives** cut the flaps (the "slots").
* **Rotary creasing wheels** press the fold lines ("scores") into the board.
* This section can be adjusted for different box lengths.

### **4. The Critical Junction: Slotter OR Die-Cutter?**
* This is the machine's key feature. A **diverting mechanism** (like a switching gate) directs the sheet:
* **PATH A (Straight through):** For simple boxes. The sheet goes directly to the **folding and counting station** to become a standard slotted container (RSC).
* **PATH B (Upwards):** For custom shapes. The sheet is lifted into the...

### **5. Flatbed Die-Cutting Station**
* The sheet is precisely positioned on a moving **bed**.
* The bed slides under the **platen** (the head), which holds the custom **die**—a steel-rule cutter mounted on a thick plywood board.
* The **platen presses down with immense hydraulic or mechanical force** (typically 300-800 tons), stamping the shape, cuts, and scores in one "clunk" or "thump."
* The sheet returns, and the waste cardboard (the "matrix") is removed, often by **stripping pins** or a manual station.

### **6. Delivery & Stacking**
* The finished box blank (either slotted or die-cut) is conveyed out.
* It may pass through a **stripper** to remove any remaining waste.
* An automatic **counter-stacker** piles a set number of blanks and delivers the stack for bundling.
