HF solding machine.Solution to wrinkling of composite machine materials

　　Reducing the tension of the traction substrate: The film is stretched too much and not shaped enough, which can easily cause wrinkling of the composite film during cooling shrinkage. Properly reducing the operating tension of the substrate can reduce wrinkling. Adjusting the flatness of the substrate. If there is a parallelism error in the guide rollers assembled on the dry laminating machine, some plastic film substrates are prone to wrinkles on the guide rollers. During production, the flatness of the substrate can be adjusted by adjusting the position of the deflection roller.

　　Composite machines and all-in-one machines both belong to the MFP category. In the past, many people believed that speed was their intuitive difference, but this is not the main factor for the significant price difference between the two. To understand the significant differences between equipment and all-in-one machines, we first need to understand their development history. In fact, it is the digitization of copiers, while all-in-one machines are the integration of printers and scanners.

　　Composite PUR hot melt adhesive is a molecular structure that contains polar and chemically active amino ester groups (- NHCOO -) or isocyanate groups (- NCO). It has excellent adhesion with materials containing active hydrogen, such as porous materials such as wood, leather, fabrics, paper, ceramics, and surface smooth materials such as plastics, metals, glass, and rubber.
