Relma (Phenolic Laminated Board)
Industrial Cutting Die Material

Relma is a reinforced phenolic composite material primarily used for manufacturing precision cutting die boards. Its unique mechanical and chemical properties make it ideal for demanding industrial applications.

Composition & Structure:

• Layered paper/fabric saturated with phenolic resin
• May contain fiberglass or carbon fiber reinforcements
• Features smooth or pre-grooved surfaces for blade mounting

Key Characteristics:
✔ Durability – Exceptional wear and fracture resistance
✔ Hardness Grades – Soft/Medium/Hard options available
✔ Thermal Stability – Withstands 120-150°C without deformation
✔ Dimensional Accuracy – ±0.1mm tolerance
✔ Lightweight – Easier handling than metal alternatives

Working Principle:

1. Mounted on 1mm steel backing plate
2. Laser-engraved with precise blade channels
3. Material (cardboard/leather/etc.) pressed through mounted blades

Industrial Applications:

• Carton box production
• Electronic circuit board insulation
• Precision leather/shoe component cutting
• Hydraulic/clicker press operations
• Laser cutting machine platforms
