Common Problems & Solutions
Poor Adhesion:
• Cause: Insufficient heat (below 170°C), contaminated surface, inadequate pressure.
• Solution: Verify temperature with IR thermometer. Clean edges with denatured alcohol. Apply 3-5 kg/cm² pressure for 10-15 seconds.
Edge Lifting:
• Cause: Cooling too quickly, panel edge not flat, wrong adhesive.
• Solution: Allow gradual cooling. Sand edges flat (max 0.2mm deviation). Use PUR adhesive for problem materials.
Visible Glue Line:
• Cause: Excessive heat, too much adhesive, wrong banding thickness.
• Solution: Reduce temperature by 10-15°C. Match banding thickness to panel exactly. Use color-matched adhesive.
Chipping During Trimming:
• Cause: Dull blades, trimming too cold, wrong tool speed.
• Solution: Replace blades frequently. Trim while still slightly warm. Router speed 18,000-22,000 RPM for clean cuts.
