In modern factory, for the aspect of packaging production, efficiency, flexibility, and quality determine competitiveness. The MZH2509-D Flexible Carton Forming Machine from Hengda is designed to help manufacturers meet these goals — offering fully automated bottom box forming for single-cover (410) and top-bottom lid cartons (0300) with precision and speed.
What Is the MZH2509-D Flexible Carton Forming Machine?
The MZH2509-D is an automatic carton folding and forming machine developed for 0410 and 0300 box types, that is side-seal box and sky-and-earth lid box. It automatically folds, glues, and presses the four corners of corrugated sheets using EVA hot melt adhesive, forming strong and neatly shaped carton bases. Unlike manual folding, this system can operate continuously, achieving 5–10 times higher productivity while ensuring consistency across every box.

Key Features and Advantages
Automatic Feeding & Positioning
The machine is equipped with an automatic feeding unit that allows multiple corrugated sheets to be stacked and fed automatically. Its auto-correction mechanism ensures precise alignment before folding, improving accuracy and reducing waste.
High-Speed Servo Adjustment
With servo-controlled width positioning, the MZH2509-D supports fast size changeovers for various carton specifications — ideal for short-run or customized packaging orders.
EVA Hot Melt Gluing Technology
The machine uses EVA hot melt glue, which offers stronger adhesion and better sealing performance compared to traditional methods. It’s clean, environmentally friendly, and produces smooth, firm box bases.
Integrated Folding and Forming Design
All folding, gluing, and pressing operations are completed within a single unit, giving each carton a consistent cube-like shape with high visual quality.
Flexible Integration
