Key Points for PET Board Edge Banding Process

1. Equipment & Tools
Use high-precision edge banding machines with pre-milling and tracking functions. Adopt sharp carbide cutters and replace them timely to prevent PET film chipping. Equip PUR glue tanks with constant temperature control (120–140℃).
2. Material Matching
Prioritize PUR hot melt adhesives (instead of EVA) for strong, water-resistant bonding. Select PET edge bands matching the board’s thermal expansion coefficient to avoid warping. Conduct batch-wise bonding tests before mass production.
3. Process Parameters
- Glue application: 180–220 g/m²
- Pressing pressure: 0.8–1.2 MPa
- Conveyor speed: 6–8 m/min
- Workshop environment: 20–25℃, 45–60% relative humidity; dust-free operation required.
4. Pretreatment & Quality Control
Lightly polish board edges to enhance glue adhesion; remove dust/debris with compressed air. Implement three-stage inspection: raw material check → in-process edge banding inspection → final quality check.
