Lum Dong(Corrugated cardboard production line/Corrugated box making machine)

In the global corrugated packaging industry, efficiency and precision are everything. Among the core components of a corrugated cardboard production line , the single facer machine plays one of the most decisive roles. It determines the stability, strength, and quality of the corrugated medium — the heart of every carton box. As carton manufacturers, corrugated board converters, and packaging machinery distributors increasingly seek high-speed, flexible production solutions, the single facer has become a critical investment for improving output and product diversity. What Is a Single Facer Machine? A single facer is the fundamental unit of a corrugated cardboard production line that bonds one liner paper and one corrugated medium to form a single-faced corrugated board . This intermediate product later becomes the core of double-wall or triple-wall boards after lamination. The single facer is responsible for: Forming the corrugation (fluting) through heated corrugating rolls ...

  When consumers face the decision of purchasing a corrugator , they often find themselves at a loss. After all, the market offers a vast array of corrugator models with varying configurations. Selecting equipment that aligns with specific needs requires a solid grasp of fundamental knowledge. As essential machinery in the packaging industry, corrugators primarily handle the production of corrugated cardboard. Production lines of different scales and requirements demand distinct corrugator types, necessitating a comprehensive evaluation of multiple factors during the selection process. Define your production requirements Before purchasing a corrugator, the primary task is to clearly define your production requirements. This encompasses key factors such as the types of corrugated board planned for production, average daily output, and facility conditions. For instance, if a company's operations primarily focus on producing Type B or Type C corrugated board with relatively low daily ...

  1. Board Warping Problem Description: After leaving the corrugated cardboard production line , the board is not flat but curves upward, downward, or to one side. Cause Analysis: Uneven moisture content: This is the core cause. Different parts of the cardboard (face paper, liner paper, core paper) have inconsistent moisture levels, leading to varying drying shrinkage rates. Upward Warping: Typically caused by excessively high moisture content in the face paper or overly dry liner paper. The face paper has a higher shrinkage rate than the liner paper. Downward Warping: Opposite of upward warping, caused by excessively high moisture content in the liner paper or overly dry face paper. The liner paper has a higher shrinkage rate than the face paper. S-curve warping: Lateral warping usually caused by uneven cross-directional temperature on the production line or inherent paper defects. Inappropriate base paper combination: Significant disparities in physical properties (basis weight,...
