Causes and Solutions for Wood Panel Cracking During Pressing

When pressing wood panels with a press machine, cracking issues may arise. This not only impairs product quality but also reduces production efficiency. Below are common causes and their corresponding solutions:
1. Uneven Glue Application
Cause: Uneven glue spreading leads to inconsistent pressure distribution during pressing, which triggers cracking.
Solution: Use a gluing machine to ensure uniform glue application, thereby improving bonding quality and eliminating pressure disparities.
2. Uneven Worktable
Cause: If the cold press machine is not properly leveled, the worktable becomes uneven, directly affecting pressing performance and uniformity.
Solution: Adjust the machine to achieve proper leveling. The worktable’s levelness is crucial for ensuring consistent and stable pressing results.
3. Irregular Wood Panels
Cause: Warped or uneven wood panels result in uneven pressure during pressing, leading to cracks.
Solution: Place soft cushioning materials (e.g., cardboard, cloth) under the uneven areas of the panels to balance pressure and minimize cracking risks.
4. Insufficient Pressing Pressure
Cause: Low pressure settings on the cold press machine lead to inadequate bonding force between wood layers, making panels prone to cracking.
Solution: Increase and adjust the machine’s pressure to ensure even, stable force during the pressing process, enhancing bonding firmness.
Conclusion
Wood panel cracking during pressing is mainly caused by uneven glue application, an unlevel worktable, irregular panels, or insufficient pressure. By using a gluing machine for uniform gluing, leveling the worktable, adding cushioning materials for irregular panels, and adjusting pressure appropriately, these issues can be effectively resolved. Proper operation of the cold press machine ensures better product quality and improved production efficiency.
