Positive & Negative Pressure Vacuum Membrane Press Machine

#

## Professional Product Introduction 

The **Positive & Negative Pressure Vacuum Membrane Press Machine** is a high-performance thermoforming & laminating equipment designed for high-grade furniture, cabinet doors, wardrobe panels, decorative moldings, and 3D profiled workpieces. By combining **bottom vacuum negative pressure** and **top pneumatic positive pressure** in a sealed heating chamber, it achieves bubble-free, tight, and long-lasting lamination on complex profiles, deep grooves, R-corners, and reverse structures that standard negative-pressure machines cannot handle.

### Core Working Principle

The machine creates a high vacuum (negative pressure up to **-0.098 MPa**) to tightly attach the film to the workpiece surface, while applying stable positive pressure (**0.3–0.6 MPa**) to enhance conformity and bonding strength. The precision temperature control system (**80–220°C**) softens the film evenly for optimal ductility, ensuring sharp edges, full corner coverage, zero blistering, and no edge lifting.

### Key Advantages

1. **Superior Lamination Quality**

   Perfect for high-gloss PVC, matte film, transfer foil, wood veneer, and leather. Delivers mirror-smooth surfaces, clear profiling, and consistent color without distortion.

2. **Wide Compatibility with Complex Profiles**

   Excels at deep grooves, raised panels, curved shapes, and undercut structures—ideal for high-end cabinet doors, flush doors, decorative wall panels, and custom moldings.

3. **High Efficiency & Low Energy Consumption**

   Dual-station / automatic loading-unloading models available; fast heating, short cycle, and low average power consumption (approx. 7–9 kW/h) reduce production cost.

4. **Stable & Durable Structure**

   Heavy-duty steel frame, imported vacuum pump, pneumatic components, and PLC touchscreen control ensure stable running, low failure rate, and long service life.

5. **Easy Operation & High Automation**

   Intuitive HMI, one-key recipes, automatic temperature/pressure/time control minimize manual intervention and improve yield.
