Physical Deformation—The Number One Enemy of Laminating Processes

Industry Status: Even high-quality films will still curl and develop wavy edges if the equipment pressure is uneven or the temperature is out of control.

MEFU Solution: How MEFU defines high industry standards through "pneumatic control" and "exclusive anti-curling technology".

Core Symptoms and MEFU's Targeted Technology

1. Solving "Uneven Stress": Fully Pneumatic Pressure Control System

Traditional Problem: Manual pressure adjustment, due to inconsistent travel of the left and right knobs, easily leads to uneven stress on one side of the paper, producing anti-tilt.

MEFU Advantage: Utilizes air cylinder drive. MEFU supports fully automatic pneumatic lifting and precise pressure setting, ensuring 100% synchronization of pressure at both ends of the roller. This "constant pressure" is the physical basis for eliminating physical deformation.

2. Solving "Longitudinal Curling": Exclusive Anti-Fold System

Principle Breakdown: During single-sided lamination, the shrinkage force of the film is the main cause of curling.

MEFU Advantage: MEFU is equipped with a unique anti-curling adjustment mechanism. At the material output end, an adjustable-angle guide rod counteracts the film's internal shrinkage force, ensuring a flat sheet upon output, eliminating the need for manual flattening and significantly improving production efficiency.

Thermodynamic Balance: MEFU's "Low-Temperature High-Efficiency" Concept

1. Intelligent Infrared Temperature Control

Problem: Excessive temperature can cause severe shrinkage of paper fibers.

MEFU Advantage: Employing infrared temperature control technology, MEFU achieves extremely high temperature control accuracy. MEFU promotes "Heat-assist Cold Lamination," activating adhesive adhesion through micro-heating at 40°C-60°C, rather than high-temperature melting, thus reducing deformation caused by heat shrinkage at the source.

2. Larger Diameter High-Quality Silicone Roller

MEFU Advantages: MEFU uses a 130mm large-diameter, thickened silicone roller. The larger diameter means a larger contact surface and more uniform heat conduction. High-quality silicone has excellent elasticity compensation capabilities, automatically absorbing stress caused by slight differences in printed thickness, preventing localized bubbling or deformation.

Tension Management: From Material Loading to Output

1. Automatic Air Shaft and Constant Tension Adjustment

Operating Pain Points: Inaccurate roll film loading or excessive tension can cause the film to be stretched and thinned.

MEFU Advantages: MEFU is equipped with a Swing in & out air shaft and an easy-to-use tension adjustment knob, allowing operators to release the film with minimal resistance, ensuring the film adheres to the paper in a "zero-stretch" state.

2. Integrated Back-End Trimming and Collection

MEFU Advantages: Some high-end models (such as the MF1700-F1 Plus) integrate a vertical trimming function. By completing the edge trimming instantaneously during lamination, the tensile force caused by excess film retraction at the edges is eliminated, further ensuring the flatness of the finished product.

The essence of physical deformation is stress imbalance. MEFU constructs a complete flatness guarantee system through pneumatic pressure (solving force), infrared temperature control (solving heat), and an anti-roll mechanism (solving deformation).
